As part of the Objective-C Hackathon I thought I'd take a shot at building a button to display progress, much like the progress button in the new iOS 7 version of the App Store. This progress button is inspired as a blend of UIButton and UIProgressView with a few other things tossed in. Maybe it will be useful, maybe it will just be fun. You decide.
- Do better testing with AutoLayout.
- Add support for better end state buttons.
- Refactor out the stupid.
- Properly handle -tintColor for the future.
- (void)viewDidLoad
{
[super viewDidLoad];
self.progressButton.delegate = self;
self.progressButton.tintColor = [UIColor blueColor];
self.progressButton.startButtonImage = [UIImage imageNamed:@"download-image"];
self.progressButton.endButtonImage = [UIImage imageNamed:@"action-image"];
}
- (void)progressButtonStartButtonTapped:(JNJProgressButton *)button
{
// Begin doing the download action or whatever asyncronous thing you need to do. Then start updating the progress progerty on the button.
}
- (void)progressButtonEndButtonTapped:(JNJProgressButton *)button
{
// The button has reached the end of the progress and the user can now do whatever the action needed.
}
- (void)progressButtonDidCancelProgress:(JNJProgressButton *)button
{
// The user has canceled the progress
}
