我正在制作一个简单的游戏应用程序,您可以在其中按下左/右按钮,然后 UIImageView 会移动和动画。这是问题所在 - 我希望 UIImageView 在触摸时停止移动
self.view.bounds.size.width
我该怎么做呢?
这是现有的代码:
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [[event allTouches] anyObject];
if([touch view] == rightbutton){
NSLog(@"touch rightbutton");
player.animationImages = [NSArray arrayWithObjects:
[UIImage imageNamed:@"linkr1.png"],
[UIImage imageNamed:@"linkr2.png"],
[UIImage imageNamed:@"linkr3.png"],
[UIImage imageNamed:@"linkr4.png"],
[UIImage imageNamed:@"linkr5.png"],
[UIImage imageNamed:@"linkr6.png"],
[UIImage imageNamed:@"linkr7.png"],
[UIImage imageNamed:@"linkr8.png"],
nil];
player.animationRepeatCount = 0;
[self.view addSubview:player];
[player startAnimating];
rightbuttontimer = [NSTimer scheduledTimerWithTimeInterval:0.01 target:self selector:@selector(rightrepeater) userInfo:nil repeats:YES];
}
if([touch view] == leftbutton){
NSLog(@"touch leftbutton");
player.animationImages = [NSArray arrayWithObjects:
[UIImage imageNamed:@"linkr1l.png"],
[UIImage imageNamed:@"linkr2l.png"],
[UIImage imageNamed:@"linkr3l.png"],
[UIImage imageNamed:@"linkr4l.png"],
[UIImage imageNamed:@"linkr5l.png"],
[UIImage imageNamed:@"linkr6l.png"],
[UIImage imageNamed:@"linkr7l.png"],
[UIImage imageNamed:@"linkr8l.png"],
nil];
player.animationRepeatCount = 0;
[self.view addSubview:player];
[player startAnimating];
leftbuttontimer = [NSTimer scheduledTimerWithTimeInterval:0.01 target:self selector:@selector(leftrepeater) userInfo:nil repeats:YES];
}
}
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [[event allTouches] anyObject];
if([touch view] == rightbutton){
NSLog(@"let go of rightbutton");
[rightbuttontimer invalidate];
[player stopAnimating];
}
if([touch view] == leftbutton){
NSLog(@"let go of leftbutton");
[leftbuttontimer invalidate];
[player stopAnimating];
}
}
- (void)rightrepeater {
CGPoint center = (CGPoint)[player center];
center.x += 10;
[player setCenter:center];
}
- (void)leftrepeater {
CGPoint center = (CGPoint)[player center];
center.x += -10;
[player setCenter:center];
}
任何帮助将不胜感激。谢谢!
