大佬教程收集整理的这篇文章主要介绍了ios – 在动画制作时更新视图的帧，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
CAKeyframeAnimation *animation = [CAKeyframeAnimation animationWithKeyPath:@"position"];
animation.duration = 100.0;
animation.path = self.animationPath.CGPath;
[view.layer addAnimation:animation forKey:@"animation"];
工作正常,但是,当尝试检测在屏幕上移动的对象上的触摸时,现在会失败：
- (BOOL)poinTinside:(CGPo@R_674_10185@point withEvent:(UIEvent *)event { for (UIView* subview in self.subviews ) { if ( [subview hitTest:[self convertPoint:point toView:subview] withEvent:event] != nil ) { [self handleTap]; return YES; } } return NO; }
它失败了,因为视图的帧不再与它在动画时在屏幕上的明显位置相同.如何让poinTinside与正在设置动画的视图一起使用？
#import "ViewController.h" @interface ViewController () @property (weak,nonatomiC) IBOutlet AnimatableView *animableView; @end @implementation ViewController - (void)animateAlongPath { UIBezierPath * path = [UIBezierPath bezierPathWithRect:self.view.frame]; CAKeyframeAnimation *animation = [CAKeyframeAnimation animationWithKeyPath:@"position"]; animation.duration = 10; animation.path = path.CGPath; animation.removedOnCompletion = NO; animation.fillmode = @"kCAFillmodeForWARDs"; [self.animableView.layer addAnimation:animation forKey:@"animation"]; } - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view,typically from a nib. } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } - (IBACtion)animate:(id)sender { [self animateAlongPath]; } -(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint LOCATIOn = [touch LOCATIOnInView: [touch view]]; CALayer * SELEctedlayer = (CALayer*)[self.animableView.layer.presentationLayer hitTest:LOCATIOn]; if(SELEctedlayer != nil) NSLog(@"touched"); else NSLog(@"dont touched"); } @end
我希望这可以帮助你
