JPPopSequenceAnimation

Runs POP Animations sequentially, one after another.

Installation

Cocoapods

Edit Podfile and add JPPopSequenceAnimation:

pod 'JPPopSequenceAnimation'

Manual

Clone the repository:

$ git clone https://github.com/Juanpe/JPPopSequenceAnimation.git

Drag and drop JPPopSequenceAnimationClasses folder into your project. Add #import "JPPopSequenceAnimation.h" to all view controllers that need to use it.

Requirements

  • iOS 7.0 or higher
  • ARC

Parameters

You can easily set the number of repetitions of sequence and set start index:

@property (nonatomic) NSInteger beginIndex;
@property (nonatomic) NSInteger numRepeats;

sequenceAnimation.numRepeats = 2;
sequenceAnimation.numRepeats = JPPopSequenceRepeatForever; // Forever

sequenceAnimation.beginIndex = 1;

If you want to get animations callbacks, you must implement protocol named ```JPPopSequenceAnimationDelegate```. 
@optional
- (void) sequenceDidStart:(JPPopSequenceAnimation *) sequence;
- (void) sequenceDidResume:(JPPopSequenceAnimation *) sequence;
- (void) sequenceDidStop:(JPPopSequenceAnimation *) sequence;
- (void) sequenceDidPause:(JPPopSequenceAnimation *) sequence;
- (void) sequenceDidNextAnimation:(JPPopSequenceAnimation *) sequence
                          atIndex:(NSInteger) index;


- (void) sequence:(JPPopSequenceAnimation *) sequence
animationDidStart:(POPAnimation *) anim
          atIndex:(NSInteger) index;

- (void) sequence:(JPPopSequenceAnimation *) sequence
 animationDidStop:(POPAnimation *) anim
          atIndex:(NSInteger) index
         finished:(BOOL) finished;

Sample Usage

POPBasicAnimation *anim = [POPBasicAnimation animationWithPropertyNamed:kPOPViewAlpha];
anim.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
anim.fromValue = @(1.0);
anim.toValue = @(0.0);
anim.name = @"fadeOut";

POPBasicAnimation *anim1 = [POPBasicAnimation animationWithPropertyNamed:kPOPViewAlpha];
anim1.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
anim1.fromValue = @(0.0);
anim1.toValue = @(1.0);
anim.name = @"fadeIn";

JPPopSequenceAnimation * sequenceAnimation = [[JPPopSequenceAnimation alloc] initWithAnimations:@[anim, anim1]];

sequenceAnimation.delegate = self;

[self.squareView addSequenceAnimation:sequenceAnimation
                               forKey:@"sequence_1"];
