Learn iOS global horse-drawn

This article shares the method of making iOS global marionettes for your reference. The specific content is as follows

Ideas:

1. Create a single case

+ (instancetype)shareManager {
 static CCPaomaView *pModel = nil;
 static dispatch_once_t once;
 dispatch_once(&once, ^{
  pModel = [[CCPaomaView alloc]initWithFrame:CGRectMake(0, 0, KScreenWidth, 0.0468 *KScreenHeight)];
 });
 return pModel;
}

2. The received data is stored in the local plist, which is not suitable for a large amount of data. Each time the first data is read, the entire plist is deleted after reading, and the rest is re-stored into the plist.

3. According to the animation agent, the monitoring animation execution is completed and the animation instance is set to nil

- (void)animationDidStop:(CAAnimation *)anim finished:(BOOL)flag{
 NSLog(@"%@",[ animationForKey:@"paoMaDeng"]);
 if ([ animationForKey:@"paoMaDeng"] == anim) {
  //Remove the first set of data  [_array removeObjectAtIndex:0];
  
  //Remove the entire plist  [CCPaomaModel removePaomaPlist];
  
  //Rewrite  [_array writeToFile:[CCPaomaModel filename] atomically:YES];
  
  //After the animation stops, set the instance to nil  _pmAniamtion = nil;
  
  //Remove the horse-drawn after the array is empty  if (_array.count &gt; 0) {
   [self showPaomaView:];
  }else{
    = YES;
   [self removeFromSuperview];
  }
  NSLog(@"%@",);
 }
}

4. Determine whether the animation instance is empty, so that the interface is switched, the marquee continues, rather than starting again

- (void)paomaAniamtion:(CGFloat)count{
 //Judge whether the animation instance exists or not, it will continue, and if it does not exist, it will be created if (_pmAniamtion == nil) {
  _pmAniamtion = [CABasicAnimation animation];
  _pmAniamtion.keyPath = @"";
  CGFloat W = CGRectGetWidth(_paomaLabel.bounds);
  _pmAniamtion.fromValue = @(W);
  _pmAniamtion.toValue = @(-W);
  _pmAniamtion.duration = _aniTime;
  _pmAniamtion.repeatCount = count;
  _pmAniamtion.removedOnCompletion = NO;  //The animation ends without removal  _pmAniamtion.fillMode = kCAFillModeForwards; //The end of the animation will remain in the end state  _pmAniamtion.delegate = self;    //Set the proxy  [_paomaLabel.layer addAnimation:_pmAniamtion forKey:@"paoMaDeng"];
 }else{
  _pmAniamtion.repeatCount = count;
 }
}

5. Switch the interface, pause and restore animation

#pragma mark -- The interface appears and disappears, create, restore, and pause animations- (void)viewWillAppear:(BOOL)animated {
 [_paomaView showPaomaView:];
 [_paomaView resumeAnimation];
}

- (void)viewWillDisappear:(BOOL)animated {
 [_paomaView pauseAniamtion];
}
