请参阅下面的帖子

我使用UITouch移动两个图像视图。当我在imageview1中移动并释放imageview1时，它会保持在该位置，但是当我开始移动imageview2时，imageview1会跳回到开始位置。如果我先移动imageview2，会发生同样的事情。我想要的是图像视图保持在释放位置，而不是跳回到开始位置。我在另一个旧的xcode projekt中使用相同的代码，它在那里工作。

以下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 {

                         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)) {

                             NSURL *musicFile;
                             musicFile = [NSURL fileURLWithPath:

                                           pathForResource:@"knapp"
                                           ofType:@"mp3"]];
                             audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:musicFile error:nil];
                             [audioPlayer play];

                         }
                         completion:^(BOOL finished){
                             //NSLog(@"Jump back");
                             NSLog(@"%ld", (long)imageView2.tag);
                         }];


    }

  }

}

我感谢任何帮助。

我解决了这个问题

我添加了一个隐藏的UIImageView，我把它放在正确的位置。

在if语句中我添加了：

completion:^(BOOL finished){
                             NSLog(@"Auto position!");
                             imageView1x.hidden = NO;
                             imageView1.hidden = YES;
                         }];

移动多个图像视图不起作用，跳回到开始位置
