Question

我使用的是错误的类型吗？ CGFloat的？浮动？ int，都给我同样的问题。

我的方法wiggleImage需要帮助。我正在尝试设置一个方法，我可以传递对象，并有一个方法，我可以调用，动画许多不同的视图，并重用代码。但是当我在方法中硬编码anchorPointX和anchorPointY值时，它工作正常。当我使用传入的值时，它会进行一些奇怪的转换，正如您从日志输出中看到的那样，它会将值更改为我传入的内容之外的其他内容。

 - (void)viewDidLoad {

 [self wiggleImage:candleFlickerView 
               duration:.45  
               curve:UIViewAnimationCurveEaseInOut 
               x:10.0 
               y:10.0 
               rotation:1 
               anchorPointX:0.2 
               anchorPointY:0.2];   
       NSLog(@"VDL  AnimationViewController....\n "); 
     }



- (IBAction)wiggleImage:(UIImageView *)image duration:(NSTimeInterval)duration
              curve:(int)curve x:(CGFloat)x y:(CGFloat)y rotation:(CGFloat)rotation 
            anchorPointX:(CGFloat)anchorPointX anchorPointY:(CGFloat)anchorPointY
{
// UN HIDE THE VIEW
image.hidden = FALSE;

// Setup the animation
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:duration];
[UIView setAnimationCurve:curve];
[UIView setAnimationRepeatCount:FLT_MAX];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationRepeatAutoreverses:YES];
//image.layer.anchorPoint= CGPointMake(0.5,0);
image.layer.anchorPoint= CGPointMake(anchorPointX, anchorPointY);


// The transform matrix 
 CGAffineTransform transform = CGAffineTransformMakeRotation(-0.45);
image.transform = transform;
// Commit the changes
[UIView commitAnimations];
NSLog(@"VDL showing wiggleImage Animation with Values of....\n ");  
NSLog(@"\nX=[%f]", anchorPointX );
NSLog(@"\nY=[%f]", anchorPointY );
NSLog(@"\nRotation=[%f]", rotation );

}


console output.

Answer 1

在wiggleImage中使用viewDidLoad之前是否已声明？确保它出现在您的类的标题中，并且标题包含在实现文件中。

将对象传递给CGFloat类型的方法
