Usage

Set Duration

[self.navigationController showSGProgress];	//defaults to 3 seconds
[self.navigationController showSGProgressWithDuration:3];  //uses the navbar tint color
[self.navigationController showSGProgressWithDuration:3 andTintColor:[UIColor blueColor];
[self.navigationController showSGProgressWithDuration:3 andTintColor:[UIColor blueColor] andTitle:@"Sending..."];
[self.navigationController showSGProgressWithMaskAndDuration:3];
[self.navigationController showSGProgressWithMaskAndDuration:3 andTitle:@"Sending..."];

[self.navigationController finishSGProgress]; //finish animation early

Custom Percentage

- (void)setSGProgressPercentage:(float)percentage;
- (void)setSGProgressPercentage:(float)percentage andTitle:(NSString *)title;
- (void)setSGProgressPercentage:(float)percentage andTintColor:(UIColor *)tintColor;
- (void)setSGProgressMaskWithPercentage:(float)percentage;
- (void)setSGProgressMaskWithPercentage:(float)percentage andTitle:(NSString *)title;

sgnavigationprogress's Issues

Why is not support iOS 6 in Cocoapods?

My heart is hurt...

Height isn't equal to iOS 7 Safari progress bar

The height of the progress bar isn't equal to the iOS 7 Safari. Safari uses 2.5 points height and this project uses just 1 point.

Fixing this is a character-change and not a big deal but it is a big deal when it comes to coherent design / interfaces. People will recognizes it better and know more what it is.
Plus I found it harder to see the bar with just 1 point in height but with 2.5 points you can see it better

Where to place [self.navigationController showSGProgressWithDuration:ellapsedSeconds]; in a UIWebView

Thank you for your sample! I'm leveraging it in my app, but have some questions.

1. which methods to place [self.navigationController showSGProgressWithDuration:ellapsedSeconds]; - (void)webViewDidFinishLoad:(UIWebView *)webView or - (void)webViewDidStartLoad:(UIWebView *)webView ?
2. How about ellapsedSeconds, where to place?

NSDate * endDate    = [NSDate date];
ellapsedSeconds     = [endDate timeIntervalSinceDate:startDate];

Thank you!

CALayer position contains NaN: [nan 43.5]

Any idea?

Cancel option should be added

On the progress in iOS 7 Safari there is also an animation for canceling the current progress. At the moment in this project we just have the option to finish the progress bar.

Finishing a progress bar even on failure can lead to weird expectations. It would be more coherent and a better UX to have a cancel animation like Safari in iOS 7.

The cancel-animation is simple and just fades the current progress bar out of the navigation bar (for a example: open web page in iOS 7 Safari and cancel loading).

What do you think? I can add it and create a pull request.

Rotating while showing progress

If you rotate the device while it is showing the progress, the progress bar is in the wrong spot

how to change mask size

Is there any chance to change the mask size (or frame) when showing progress?

Now it looks a full screen mask that stops user interaction available with UI elements (like refresh, cancel...) during download web page

changeSGProgressWithTitle restores the wrong navigation view controller title

if a modal view controller with a title is presented from a main view controller, and then changeSGProgressWithTitle is called on the main view controller, the title of the presented view controller is restored instead of the title of the main controller.

either finishSGProgress or cancelSGProgress will cause that
