Question

我有一个动画熊的代码，但我需要检查它的动画和常规UIImageView之间的碰撞。有什么建议？我查看了其他答案但我的代码却不一样。这是我到目前为止所拥有的。或者我应该使用SpriteKit。我宁愿不要。

- (void)viewDidLoad {

NSArray *imageNames = @[@"bear1.gif", @"bear2.gif", @"bear3.gif", @"bear4.gif",
                        @"bear5.gif", @"bear6.gif"];

NSMutableArray *images = [[NSMutableArray alloc] init];
for (int i = 0; i < imageNames.count; i++) {
    [images addObject:[UIImage imageNamed:[imageNames objectAtIndex:i]]];
}

// Normal Animation
UIImageView *animationImageView = [[UIImageView alloc] initWithFrame:CGRectMake(768, 800, 169, 217)];
animationImageView.animationImages = images;
animationImageView.animationDuration = 0.5;


[self.view addSubview:animationImageView];
[animationImageView startAnimating];


[UIView animateWithDuration:7 delay:1 options:UIViewAnimationOptionRepeat animations:^{
    [UIView setAnimationRepeatCount:INFINITY];
    animationImageView.frame = CGRectMake(-10, 800, 169, 217);
} completion:^(BOOL finished) {
    animationImageView.hidden = YES;
}];

[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.

}

在动画块中，您可以查看动画视图的帧何时越过或即将穿过UIImageView的帧。满足此条件时，您将停止动画

在动画数组和UIImages应用程序开发之间创建碰撞
