Objective c 旋转UIImageView的动画会旋转其他对象

到目前为止，我的代码是

rotateButton = [UIButton new];
    rotateButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [rotateButton setFrame:CGRectMake(334, 80, 100, 20)];
    [rotateButton addTarget:self action:@selector(rotateImageView:Degrees:InTimePeriod:) forControlEvents:UIControlEventTouchUpInside];
    [rotateButton setTitle:@"Rotate" forState:UIControlStateNormal];
    [self.view addSubview:rotateButton];

-(void)rotateImageView
{
    [self rotateImageView:imageView Degrees:90 InTimePeriod:1.5];
}

-(void)rotateImageView:(UIImageView*)imageView Degrees:(NSInteger)degrees InTimePeriod:(float)time
{
    CABasicAnimation *rotate;
    rotate = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];
    rotate.fromValue = [NSNumber numberWithFloat:0];
    rotate.toValue = [NSNumber numberWithFloat:DEGREES_TO_RADIANS(degrees)];
    rotate.duration = time;
    rotate.repeatCount = 1;
    [imageView.layer addAnimation:rotate forKey:@"Rotate"];
}

但是，我用来开始旋转的按钮是我按下按钮后旋转的对象，而不是我希望它旋转的imageView。如何使imageView旋转？

更改

    [rotateButton addTarget:self action:@selector(rotateImageView:Degrees:InTimePeriod:) forControlEvents:UIControlEventTouchUpInside];

您将@selector（rotateImageView:Degrees:InTimePeriod:）设置为按钮的操作。按钮将其自身作为@selector（rotateImageView:Degrees:InTimePeriod:）的第一个参数发送给默认值@selector（rotateImageView:Degrees:InTimePeriod:），事实上，当函数运行时，*imageView指向按钮，这就是为什么按钮会旋转，但图像视图会显示。按照aeubanks的说法执行。

如果是这样，您的某个地方会出现错误。您可能不应该直接访问imageView，而是这样做：[self rotateImageView:self.imageView Degrees:90 InTimePeriod:1.5]；

    [rotateButton addTarget:self action:@selector(rotateImageView) forControlEvents:UIControlEventTouchUpInside];

 [rotateButton addTarget:self action:@selector(rotateImageView:Degrees:InTimePeriod:) forControlEvents:UIControlEventTouchUpInside];
