Question

我有一个可移动的按钮，并希望在用户点击该按钮时执行一个方法 - 这可能在ios中吗？

我编写了以下代码，但需要完成动画才能触发该功能：

[arrowButton addTarget:self action:@selector(presentMainWindow) forControlEvents:UIControlEventTouchUpInside];


[UIView animateWithDuration:kAnimationDuration
                          delay:.2f
                        options:UIViewAnimationOptionCurveEaseInOut 
                     animations:
     ^{
         [arrowButton setTransform:CGAffineTransformMakeTranslation(kButtonShift, 0)];
         [arrowButton setFrame:CGRectMake(arrowButton.frame.origin.x + kButtonShift, arrowButton.frame.origin.y, arrowButton.frame.size.width, arrowButton.frame.size.height);
     } 
                     completion:nil];

Answer 1

我发现您只需将 UIViewAnimationOptionAllowUserInteraction 选项添加到动画中即可处理动画和交互：

 [UIView animateWithDuration:kAnimationDuration
                          delay:.2f
                        options:UIViewAnimationOptionCurveEaseInOut | UIViewAnimationOptionAutoreverse | UIViewAnimationOptionAllowUserInteraction
                     animations:
     ^{
         [arrowButton setTransform:CGAffineTransformMakeTranslation(kButtonShift, 0)];
    } 
                     completion:nil];

只要动画只是你能看到的效果并且不能触摸你只能在制作动画时单击按钮，如果你自己制作这样的动画

我不知道这是否是最佳解决方案，但它是一种可行的解决方案。

- (IBAction)startanimation:(id)sender {

    old = CGPointMake(arrowButton.frame.origin.x,arrowButton.frame.origin.x);
    [self ani];


}
- (void)ani {
    NSLog(@"ani1");

    if (arrowButton.frame.origin.x < old.x + kButtonShift ) {

        NSTimer*myTimer;

        myTimer = [NSTimer scheduledTimerWithTimeInterval:kTimeInterval/kButtonShift*4 target:self selector:@selector(ani2) userInfo:nil repeats:NO];

}
}
- (void)ani2 {
    NSLog(@"ani2");

    arrowButton.frame = CGRectMake((arrowButton.frame.origin.x + 1), arrowButton.frame.origin.y, arrowButton.frame.size.width, arrowButton.frame.size.height);
    [self ani];

}
