爲的UIImageView旋轉動畫旋轉別的

Question

到目前爲止我的代碼是

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，我用它來啓動旋轉按鈕後，我按下按鈕，而不是ImageView的，我希望它是旋轉對象旋轉。我該如何使imageView旋轉？

Answer 1

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

您設置的@selector（rotateImageView：學位：InTimePeriod :)作爲button.The按鈕的作用自送他作爲第一個參數是@selector（rotateImageView：Degrees：InTimePeriod :)作爲默認值，實際上，當函數運行時，* imageView指向按鈕，這就是按鈕旋轉的原因，但是按照aeubanks的說法，imageView.Do。

Answer 2

變化

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

到

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