touchesbegan和touchesmoved

Question

我的问题是，当我按下一个按钮时，它有一个声音，此时我触摸另一个手指的同一个按钮，它也有声音。当我已经按住同一个按钮上的手指时，我可以禁用另一个触摸吗？正如TouchesMoved一样。

int touchesCount;

- （void）touchesBegan：（NSSet *）触及withEvent：（UIEvent *）event {

UITouch *touch = [touches anyObject];

CGPoint touchLocation = [touch locationInView:self.view];

if(CGRectContainsPoint(img1.frame,touchLocation)){

    if (!img1.isHighlighted && touchesCount < 1){

        [img1 setHighlighted:YES];
        [img2 setHighlighted:NO];


        NSLog(@" Image 1");

        CFBundleRef mainBundle = CFBundleGetMainBundle();
        CFURLRef soundFileURLRef;
        soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"c", CFSTR ("mp3"), NULL);

        UInt32 soundID;
        AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
        AudioServicesPlaySystemSound(soundID);
    }
}else {
    [img1 setHighlighted:NO];

}if (CGRectContainsPoint(img2.frame,touchLocation)){

    if (!img2.isHighlighted && touchesCount < 1){

        [img2 setHighlighted:YES];
        [img1 setHighlighted:NO];

        NSLog(@" Image 2");

        CFBundleRef mainBundle = CFBundleGetMainBundle();
        CFURLRef soundFileURLRef;
        soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"d", CFSTR ("mp3"), NULL);

        UInt32 soundID;
        AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
        AudioServicesPlaySystemSound(soundID);
    }
}else {
    [img2 setHighlighted:NO];
}

}

- （void）touchesMoved：（NSSet *）触及withEvent：（UIEvent *）event {

UITouch *touch = [touches anyObject];

CGPoint touchLocation = [touch locationInView:self.view];

if(CGRectContainsPoint(img1.frame,touchLocation)){

    if (!img1.isHighlighted && touchesCount < 1){

        [img1 setHighlighted:YES];
        [img2 setHighlighted:NO];

        NSLog(@" Image 1");

    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef soundFileURLRef;
    soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"c", CFSTR ("mp3"), NULL);

    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);
    }
}else {
    [img1 setHighlighted:NO];

}if (CGRectContainsPoint(img2.frame,touchLocation)){

     if (!img2.isHighlighted && touchesCount < 1){

         [img2 setHighlighted:YES];
         [img1 setHighlighted:NO];

    NSLog(@" Image 2");

    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef soundFileURLRef;

    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);
     }
}else {
    [img2 setHighlighted:NO];
}

}

- （void）touchesEnded：（NSSet *）触及withEvent：（UIEvent *）事件{

[img1 setHighlighted:NO];
[img2 setHighlighted:NO];

}

• （void）touchesCancelled：（NSSet *）触及withEvent：（UIEvent *）event {     [self touchesEnded：touches withEvent：event]; }

由于您使用点击坐标检测“按钮”的触摸，因此您只需在touchesBegan中添加逻辑，以检查您的按钮是否已被点击。例如。将“BOOL button1Tapped”变量添加到类中。
