Installing DJI-SDK-iOS (4.16)
Installing DJI-UXSDK-iOS (4.16)
Installing DJIWidget (1.6.6)
Installing DJIFlySafeDatabaseResource (01.00.01.18)
Generating Pods project
Integrating client project

[!] Please close any current Xcode sessions and use `UXSDKOCSample.xcworkspace` for this project from now on.
Pod installation complete! There is 1 dependency from the Podfile and 1 total pod
installed.

Note: If you saw "Unable to satisfy the following requirements" issue during pod install, please run the following commands to update your pod repo and install the pod again:

pod repo update
pod install

Run Sample Code

Developers will need to setup the App Key by editing the sample code's info.plist, after generating their unique App Key.

For the Objective-C sample app, the key value DJISDKAppKey should to be added to "Info.plist" with your unique app key as a string.

For the Swift sample app, the DJISDKAppKey is present in the "Info.plist" - developers just need to add their unique key. In both cases developers will still need to update the Bundle Identifier .

One of DJI's aircraft or handheld cameras will be required to run the sample application.

DJIWidget Integration

Starting from DJI iOS SDK 4.7, we have replaced the VideoPreviewer with DJIWidget for video decoding. Please add the following line to your Podfile to install it to your Xcode project:

pod 'DJIWidget', '~> 1.6.6'

Note: Remember to add the use_frameworks! in the pod file.

How Translate the Labels from UILibrary

Hi Everyone,

I am developing a App using the UILibrary in my country (Brazil) and I need to translate each text to Portuguese (PT).

Is there a way to make the Localization easier in that Library ?

Thanks.

DUXStatusBarView Mavic Air, Preflight remains on Pending...

SDK 4.5.1
Mavic AIR latest firmware
Tested with your swift code example.

DUXDefaultLayoutView and DUXStatusBarView remains on Pending... and does not switch to Ready to Fly

Set "App Output Mode" with HDMI

iOS UXSDK 4.5.1
iOS SDK 4.5.2
iPad mini 4
M600 Pro
Lightbridge 2

I want to know how to set "App Output Mode" with HDMI.

In DJIGo4 app, I can see video preview with "EXT port disabled" and "App Output Mode == HDMI" configuration.
But I can't see video preview with Mobile-UXSDK-iOS sample code.

I found a trick that is..

1. Open the sample app. and click in to the "DefaultLayoutView".
   I can't see video preview at this point!
2. Open the DJI Go App. and change the "EXT port disabled" and "App Output Mode == HDMI"
   (bandwidth is also set HDMI 100%)
3. Switch back to the sample app.
   then I can see the video preview!.

So, I want to know,

1. How to set the App Output mode with HDMI.
2. Is there UX lib. for configuring Lightbride2 like DJIGo app. has.

How can I turn on the focus peaking and over exposure warning function?

I can not found those to switchers in DUXCameraSettingsController. Dose DJI UXSDK provides those two functions to developers? How can I turn on them?

DUXStatusBarViewController remaining time setting 00:00 when grounded

DJI go 4 app shows remaining time as --:-- when drone grounded.

But when I use DUXStatusBarViewController, it shows 00:00 which is incorrect.

Is there anyway to set remaining fly time as --:-- when drone grounded just like DJI go 4 app ?

Any help would be appreciated.
Thanks

DULExposureSettingsController crash with DJI SDK 4.1

Am curious if the current UI library (4.0.1.1.0.0) is compatible with SDK 4.1. Most of the widgets work but when using the DULExposureSettingsController we get the following error:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[DJICameraCapabilities sharedInstance]: unrecognized selector sent to class 0x107bd2578'

To verify this all I did was update the UI Lib swift project podfile to this:

#platform :ios, '9.0'

target 'UILib Sample' do
pod 'DJI-SDK-iOS', '~ > 4.1'
pod 'DJI-UILibrary-iOS', '~ > 4.0.1.1.0.0'
end

Whenever trying to access the "Panels and Collections" view it immediately crashes with the error above.

Do we need to wait for an update to the UI library or is there a workaround in the interim?

Thank you.

IB Designables: Failed to render and update auto layout status for ViewController

We are seeing the following error in Xcode 9.1, but not in Xcode 9.0:

/Base.lproj/Main.storyboard: error: IB Designables: Failed to render and update auto layout status for ViewController (BYZ-38-t0r): dlopen(DJIUILibrary.framework, 1): Library not loaded: @rpath/DJISDK.framework/DJISDK
Referenced from: DJIUILibrary.framework
Reason: image not found

This error prevents our view controller in the storyboard from updating. All we see are white boxes as shown in the image below:

This makes it very difficult to do layout since we have no preview. It's not the end of the world and we can work around it, but appears to be an imcompatibility with Xcode 9.1. We can still build and run our project.

Here is the error from the issue navigator:

We've been trying to find a workaround but no luck yet. Does anyone have any ideas on how to resolve this?

OSMO PRO support

SDK 4.5.2

DUXDefaultLayoutViewController
DUXExposureSettingsMenu
DUXCameraSettingsMenu

The camera and menu settings doesn't work when I connect an OSMO PRO X5 device.
The X5 camera and menu settings works perfect when I connect an Inspire 1 with X5.

OSMO PRO and X5 on the latest FW

The Status Bar remains on CAN NOT TAKE OFF
This could be fixed to READY TO SHOOT when an OSMO device is connected.

DUXExposureSettingsMenu is not working

DUXExposureSettingsMenu is not working

1. DUXExposureSettingsMenu widget is not working as a standalone widget when adding it from the code (addWidget()) or interface builder.
2. iOS UXSDK 4.6
3. DJI Phantom 4
4. It's not working on the ios versions starting from the ios 10 (this is what we tried)
5. We are testing this on iPhone 6s
6. Xcode 9.4.1
7. We tried to check the functionality of this widget in the provided sample code - UXSDKDemo, but that widget is only working when using the DUXDefaultLayoutViewController and not as the standalone widget added in the interface builder or in the code.

DUXCameraConfigStorageWidget autolayout errors

Using DUXCameraConfigStorageWidget with auto-layout constraints and without causes constant autolayout errors when capturing photos or video. This widget should automatically size correctly without triggering auto layout errors.

Steps to reproduce
In an Xcode storyboard, place a UIView and give it the custom class DUXCameraConfigStorageWidget. Run the application and have the aircraft record video or photo, and observe the autolayout errors printing in the log and hanging the debugger (if you have a breakpoint set).

[LayoutConstraints] Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)
(
"<NSAutoresizingMaskLayoutConstraint:0x1c829fd10 h=&-- v=&-- DUXCameraConfigStorageWidget:0x11be8fd40.width == 197 (active)>",
"<NSLayoutConstraint:0x1c8489ab0 DUXCameraConfigStorageWidget:0x11be8fd40.width == 149 (active)>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x1c8489ab0 DUXCameraConfigStorageWidget:0x11be8fd40.width == 149 (active)>

Environment

• DJI UX SDK 4.6
• DJI UI SDK 4.6.1
• Xcode 9 or 10
• Any Device
• Any iOS

SDK 4.8 is broken - does not connect to aircraft at all

DJI UX SDK 4.8 seems to be broken.

Working on an app that uses SDK v 4.7.1 (installed as recommended, using Cocoapods) to perform some readings from the Vision and ultrasonic sensors, while using UX SDK 4.7.1 and DJIWidget 1.1 to provide FPV & configuration & status to the app, by using DUXDefaultLayoutViewController as a child of a Container View. Works fine, as expected, while connected to a Phantom 4 Pro v2, by using an iPad Air with iOS 12.1 . The project itself is built using Xcode 10.1 .

Upon migrating to (UX) SDK v 4.8, as well as DJIWidget 1.2, the app suddenly stops working - no FPV, sensors are no longer giving any output - the red indicator that signals that there is no Vision sensor output is always on - , and there is a permanent red triangle shown on at the top right side of the screen. The menu at the checklist does not report anything wrong. When running DJI Go 4, the app doesn't report anything wrong with the aircraft, either.

Went back to (UX) SDK v 4.7.1, while keeping DJIWidget 1.2, and the app starts working again as expected.

If required, I can provide a minimal build of my app to reproduce the issue.

Menu button is now gone with version 4.3

Hi,
In version 4.2 we used to have a Menu button that would allow us to format the SD Card and other things, now it is gone, how can I show it again?

Black Screen using iOS 11 and iPhone 6-7

Hi,

After updating our iPhones (iPhone 6 and 7 so far) to iOS 11, and using the SDK version 4.3 and 4.3.1, when we connect the drone to the phone, we get a black image for around 40 seconds or a minute before we can actually see what the drone is seeing.
Please let me know if you need more info.

Thanks

VideoPreviewer instance used in FPVView is different from VideoPreviewer.instance

I noticed that the instance of VideoPreviewer class in FPVView is different from the instance obtained by calling VideoPreviewer.instance. Can you expose more details such as how to obtain, how to call its methods about the VideoPreviewer instance used in FPVView?

Request for Add/Remove Widget Example for Demo Project

DJI Team, thank you for the Mobile UILibrary on iOS. I really appreciate this open source project.

I do have a question. I would like to use the DULDefaultLayoutViewController and customise it by adding or removing widgets. How can I do that without having to create my own view and subclassing the widget elements?

[MAJOR BUG] Camera snap sound repeats (retain cycle?)

Hi DJI, this is a major bug and I hope we can resolve this issue asap.
To recreate this problem, simply run the demo project of Mobile-UILibrary-iOS. Of course, make sure you are registered with the DJISDKAppKey and match it with the Bundle ID. Oh and make sure the drone is connected to the Drone remote controller. And make sure the Drone remote controller to connected to the Device (iPhone, iPad).

After the App registered successfully, go into any camera view take a photo. Press back. Then go into any camera view again, then take a photo. There you go. The issue. You can hear two camera shutter sound.

To make this problem more clear, press back, go into any camera view take a photo. Then you should hear three camera shutter sound playing almost concurrently one after another.

To make this problem even clearer, press back, go into any camera view take a photo. Then you should hear four camera shutter sound player playing almost concurrently one after another.

Please kindly help us fix this major issue.
Thank you.

Does DULRemainingFlightTimeWidget Work?

We are trying to get DULRemainingFlightTimeWidget working in our app and it doesn't seem to render anything. We are currently using a UIView with a custom class of DULRemainingFlightTimeWidget but whenever testing either bridged or connected directly to the aircraft it doesn't render anything. We are using UILibrary 4.0.1.1.0.0 with Phantom 4 and Mavic Pro. iOS devices we've tested with are iPhone 6 and iPad Mini as well as simulated versions. Other widgets work just fine in our app. Any thoughts would be appreciated.

Thanks.

[UI BUG] Please Fix UILibrary Orientation UI Bug

Hi DJI,
I found found this bug? I am not sure if this is a bug but when the device is in the portrait orientation the collection looks unpleasant because all the text are squished together. I think it should look like the one when the device is in the portrait orientation.

Is this a bug? If not, how can I make it so that the camera view looks like the one during portrait orientation when I am in the landscape orientation?

Landscape

Portrait

Thanks to the DJI Team for the support as always [:

Finally, the UILibrary. However i encounter this issue when trying to build "dyld: Symbol not found: _DJISupportedCameraPhotoShootModeRange". I added the Library using cocoapod, I'm writing my app in Objective-C, any idea how to solve this? Thank you.

DULAircraftBatteryTemperatureChecklistItem Issues

First of all, the header file for this DULAircraftBatteryTemperatureChecklistItem CheckListItem is missing in the library.

To solve it, I added the following header in the library : DULAircraftBatteryTemperatureChecklistItem.h
`
#import "DULPreflightChecklistItem.h"

@interface DULAircraftBatteryTemperatureChecklistItem : DULPreflightChecklistItem

@EnD
`

Furthermore, if we try to remove this item from the DefaultCheckList, the application crashes.
This issue is really annoying for people using A3+LB2 without DJI batteries because if we don't remove this CheckListItem, the item remains in PendingState and, the complete PreflightCheckList remains also in Pending State.

This is only valid for this item. Others items can be removed from the DefaultCheckList without problem. It seems that some Listeners are not properly removed from the component when the component itself is removed from the list.

This is the code crashing the app.
if (item is DULAircraftBatteryTemperatureChecklistItem) { item.stopChecking() DULPreflightChecklistManager.default().remove(item) }
Could you please provide us a fix or provide us the library code to fix this issue ourself?

Can't get Mobile-UXSDK-iOS to build in non bitcode and framework environment

I'm trying to get an FPV view, but the SDKs confound me at every step.

We're running in a cocoapods environment, ultimately the SDKs will be dependents of another cocoapod.
We do not use Bitcode.
We use use_frameworks! for dynamic frameworks and we're in a dual Swift/Obj-c environment.
I've tried using DJIWidget but we can't get that to load either (I'll make a seperate issue).

So, 1st Problem, I created a empty demo project here : https://github.com/valentary/DJISDKTest
It's a default single view swift project, all I did was to configure the podfile and run pod install.
If we try and build we get a link error :
ld: '<home_dir>/DJISDKTest/DJISDKTest/Pods/DJI-SDK-iOS/iOS_Mobile_SDK/DJISDK.framework/DJISDK' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. file '<home_dir>/DJISDKTest/DJISDKTest/Pods/DJI-SDK-iOS/iOS_Mobile_SDK/DJISDK.framework/DJISDK' for architecture arm64

This only happens if I include the DJI-UXSDK-iOS pod. We don't want bitcode anyway, so I'm a bit unclear why it's asking for it.

Incorrect license comments in VideoPreviewer/VideoFrameExtractor.h and .m ?

The LICENSE.txt file states that Sample code is offered under MIT License, however the sample VideoPreviewer's VideoFrameExtractor.h and .m files contain comments that it is LGPL code from iFrameExtractor.

However, based on a diff of these files against the iFrameExtractor files it appears VideoFrameExtractor is completely different from iFrameExtractor, so unless iFrameExtractor is being linked in via .a files, which I don't see, the comments in your source code may be incorrect.

Please delete the incorrect comments or update your license file.

This is important for anyone wanting to use this sample code in a published app as we need to correctly attribute any open source that we use in our own licenses.
