解决方案
请参阅下面的帖子
我使用 UITouch 移动两个图像视图。当我在 imageview1 周围移动并释放 imageview1 时，它会停留在该位置，但是当我开始移动 imageview2 时，imageview1 会跳回起始位置。如果我先移动 imageview2，也会发生同样的事情。我想要的是图像视图保持在释放位置，而不是跳回起始位置。我在另一个旧的 xcode projekt 中使用了相同的代码，它在那里工作得很好。
这是我正在使用的代码-
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
// get touch event
UITouch *touch = [[event allTouches] anyObject];
CGPoint touchLocation = [touch locationInView:self.view];
if ([touch view] == imageView1 && imageView1.tag == 0) { // If touched view is imageView1 , then assign it its new location
imageView1.center = touchLocation;
[self.view bringSubviewToFront:imageView1];
}
if ([touch view] == imageView2 && imageView2.tag == 0) { // If touched view is imageView2, then assign it its new location
imageView2.center = touchLocation;
[self.view bringSubviewToFront:imageView2];
[imageView2 setFrame:CGRectMake(imageView2.frame.origin.x,
imageView2.frame.origin.y,68,138)];
}
}
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
UITouch *touch = [[event allTouches] anyObject];
CGPoint touchLocation = [touch locationInView:self.view];
NSLog(@"%@", NSStringFromCGPoint(touchLocation));
if ([touch view] == imageView1 && imageView1.tag == 0) {
if ((touchLocation.x >= 289 && touchLocation.x <= 381) && (touchLocation.y >= 99 && touchLocation.y <= 135)) {
//NSLog(@"imageView1");
imageView1.tag=1;
[UIView animateWithDuration:0.35
delay:0.0
options: UIViewAnimationOptionAllowAnimatedContent
animations:^{
imageView1.frame = CGRectMake(244.0, 64.0, 112, 97);
NSURL *musicFile;
musicFile = [NSURL fileURLWithPath:
[[NSBundle mainBundle]
pathForResource:@"knapp"
ofType:@"mp3"]];
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:musicFile error:nil];
[audioPlayer play];
audioPlayer.delegate = self;
}
completion:^(BOOL finished){
NSLog(@"Auto adjust!");
}];
}
else {
[UIView animateWithDuration:0.35
delay:0.0
options: UIViewAnimationOptionAllowAnimatedContent
animations:^{
imageView1.frame = CGRectMake(50, 626, 112, 97);
}
completion:^(BOOL finished){
NSLog(@"imageView1!");
//NSLog(@"Jump back!");
NSLog(@"%ld", (long)imageView1.tag);
}];
}
}
if ([touch view] == imageView2 && imageView2.tag == 0) {
if ((touchLocation.x >= 426 && touchLocation.x <= 450) && (touchLocation.y >= 210 && touchLocation.y <= 240)) {
//NSLog(@"imageView2");
imageView2.tag=1;
[UIView animateWithDuration:0.35
delay:0.0
options: UIViewAnimationOptionAllowAnimatedContent
animations:^{
imageView2.frame = CGRectMake(408.0, 152.0, 68, 138);
NSURL *musicFile;
musicFile = [NSURL fileURLWithPath:
[[NSBundle mainBundle]
pathForResource:@"knapp"
ofType:@"mp3"]];
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:musicFile error:nil];
[audioPlayer play];
audioPlayer.delegate = self;
}
completion:^(BOOL finished){
NSLog(@"Auto adjust!");
}];
}
else {
[UIView animateWithDuration:0.35
delay:0.0
options: UIViewAnimationOptionAllowAnimatedContent
animations:^{
imageView2.frame = CGRectMake(82, 519, 49, 99);
}
completion:^(BOOL finished){
//NSLog(@"Jump back");
NSLog(@"%ld", (long)imageView2.tag);
}];
}
}
}
我很感谢任何帮助。
