DZNPhotoPickerController

A photo search/picker for iOS using popular providers like 500px, Flickr, Instagram, Google, Bing & Getty Images. This control tries to mimic as close as possible UIKit's UIImagePickerController in terms of features, appearance and behaviour.

Features

Search photos on mutiple service providers (500px, Flickr, Instagram, Google, Bing & Getty Images)
Auto-completed typing for easier search (using Flickr's API as a common denominator).
Present the photo picker with a pre-defined search term to automatically start searching.
Exact same UI layouts and behaviours than UIImagePickerController.
Edit photo selections with cropping guides : square, circular (like the Contacts app) and custom size.
Circular cropping mode for using with UIImagePickerController (check on UIImagePickerController+Edit).
Creative Commons licences optional filtering.
App Store safe. Innapropriate content disabled for all services.
Option for disabling full sized photo download and retrieving metadata only.
iPhone (3.5" & 4") and iPad support.
ARC & 64bits support.
Localization support (UI strings use NSLocalizedString but it's up to you to localize them on your app)

How to use

For complete documentation, visit CocoaPods' auto-generated doc

Step 1

Import "DZNPhotoPickerController.h"

Step 2

Before even creating a new instance of DZNPhotoPickerController, it is recommended that you register to the photo services APIs your will need, on your UIViewController's class method +initialize, like so:

+ (void)initialize
{
    [DZNPhotoPickerController registerService:DZNPhotoPickerControllerService500px
                                  consumerKey:YOUR_500px_KEY
                               consumerSecret:YOUR_500px_SECRET
                                 subscription:DZNPhotoPickerControllerSubscriptionFree];
    
    [DZNPhotoPickerController registerService:DZNPhotoPickerControllerServiceFlickr
                                  consumerKey:YOUR_Flickr_KEY
                               consumerSecret:YOUR_Flickr_SECRET
                                 subscription:DZNPhotoPickerControllerSubscriptionFree];
}

Step 3

Creating a new instance of DZNPhotoPickerController is very similar to what you would do with UIImagePickerController:

DZNPhotoPickerController *picker = [[DZNPhotoPickerController alloc] init];
picker.supportedServices = DZNPhotoPickerControllerService500px | DZNPhotoPickerControllerServiceFlickr;
picker.allowsEditing = YES;
picker.delegate = self;
    
[self presentViewController:picker animated:YES completion:NO];

You can additionally set more properties:

picker.initialSearchTerm = @"Surf";
picker.cropMode = DZNPhotoEditorViewControllerCropModeCircular;
picker.enablePhotoDownload = YES;
picker.supportedLicenses = DZNPhotoPickerControllerCCLicenseBY_ALL;
picker.allowAutoCompletedSearch = YES;

You can opt-in for block methods instead of using the delegate's methods:

picker.finalizationBlock = ^(DZNPhotoPickerController *picker, NSDictionary *info) {
    //Your implementation here
};
    
picker.failureBlock = ^(DZNPhotoPickerController *picker, NSError *error) {
    //Your implementation here
};
    
picker.cancellationBlock = ^(DZNPhotoPickerController *picker) {
    //Your implementation here
};

Standalone Image Editor

You can install it as a subspec (if you're not using DZNPhotoPickerController)

pod 'DZNPhotoPickerController/Editor'

If you already have an image to edit, simply do:

DZNPhotoEditorViewController *editor = [[DZNPhotoEditorViewController alloc] initWithImage:self.myImage];
editor.cropMode = DZNPhotoEditorViewControllerCropModeCustom;
editor.cropSize = CGSizeMake(CGRectGetWidth(self.view.frame), 200.0);

[editor setAcceptBlock:^(DZNPhotoEditorViewController *editor, NSDictionary *userInfo){
        
    //Your implementation here
}];
    
[editor setCancelBlock:^(DZNPhotoEditorViewController *editor){
        
    //Your implementation here
}];

// The view controller requieres to be nested in a navigation controller
UINavigationController *controller = [[UINavigationController alloc] initWithRootViewController:navigation];
[self presentViewController:controller animated:YES completion:NULL];

Circular and Custom Edition

Another great feature of DZNPhotoPickerController is to allow circular edit mode when using UIImagePickerController, just like the Contact app when editing a user's avatar image. Please note that the circular mode still exports a squared image since it's sole purpose is for croping alignment. If you need to present a circular image in your app, you will need to implement it yourself.

Its use is really straightforward:

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
picker.delegate = self;
picker.cropMode = DZNPhotoEditorViewControllerCropModeCircular;
    
[self presentViewController:picker animated:YES completion:NULL];

Block Support

There is also block support for UIImagePickerController! It replaces the 2 traditional delegate methods with 2 block properties instead:

picker.finalizationBlock = ^(UIImagePickerController *picker, NSDictionary *info) {
    //Your implementation here
};
    
picker.cancellationBlock = ^(UIImagePickerController *picker) {
     //Your implementation here
};

Take a look into the sample project. Everything is there.
The pod dependencies are not being versioned, so before running the project be sure to call:

pod install
