RNBlurModal adds depth to the traditional modal/alert view. Calling the view is incredibly similar to setting up and showing a UIAlertView. You can also setup your own custom views and display them with a blurry background. The goal is to truly draw the user's focus directly to your alert using natural effects. This project works on all iOS devices at all orientations with ARC.
Super simple. Just drag & drop RNBlurModalView.h/.m into your project. In your Project, find the Build Phases tab and expand Link Binary With Libraries. Add the following frameworks to your project:
- QuartzCore.framework
- Accelerate.framework
Additionally in your project, under the Build Phases tab, expand Compile Sources and add RNBlurModalView.m.
The simplest way to get up and running with RNBlurModalView is to display a default view. Inside of your view controller, write the following code:
RNBlurModalView *modal = [[RNBlurModalView alloc] initWithViewController:self title:@"Hello world!" message:@"Pur your message here."];
[modal show];You can also create a modal view with your own custom UIViews:
RNBlurModalView *modal = [[RNBlurModalView alloc] initWithViewController:self view:view];
[modal show];The only thing I'll warn users about is that animations beneath the modal will be "paused". When it comes down to it, I am overlaying a UIImage on top of your controller. I've tried messing with some hacky CADisplayLink methods, but I can't seem to get a screenshot of the present state of the controller, just the configuration.
Set a couple of different properties of your modal view to change how it appears:
@property (assign) CGFloat animationDuration;
@property (assign) CGFloat animationDelay;
@property (assign) UIViewAnimationOptions animationOptions;For brevity, you can instead set these properties in the show: and hide: methods.
// show
- (void)show;
- (void)showWithDuration:(CGFloat)duration delay:(NSTimeInterval)delay options:(UIViewAnimationOptions)options completion:(void (^)(void))completion;
// hide
- (void)hide;
- (void)hideWithDuration:(CGFloat)duration delay:(NSTimeInterval)delay options:(UIViewAnimationOptions)options completion:(void (^)(void))completion;As always, I try to include some helpers in case there are other objects that need to be notified of custom events.
extern NSString * const kRNBlurDidShowNotification;
extern NSString * const kRNBlurDidHidewNotification;@property (assign, readonly) BOOL isVisible;The drawing for the dismiss button comes from David Keegan's awesome KGModal project.
The blurring algorithm is applied from this awesome blog post.
