如何在ios中为可调整大小的图像设置缩放属性的值?

- (IBAction)changeToLdpi:(id)sender
{


    myImage= [myImage resizableImageWithCapInsets:UIEdgeInsetsMake(50, 150,50,150) resizingMode:UIImageResizingModeStretch];
    //self.scale=2.0;
   CIImage *scaledImg=[[CIImage alloc]initWithImage:myImage];


   myImage=[UIImage imageWithCIImage:scaledImg scale:2.0 orientation:UIImageOrientationLeft];


    [self->imageView setImage:myImage];



//[_view addSubview:imageView];
}

我使用过这段代码。 但规模:2.0不起作用。 建议我怎么做?

使用此方法可行

 myImage= [myImage resizableImageWithCapInsets:UIEdgeInsetsMake(50, 150,50,150)];

  UIImage *picture = [UIImage imageWithCGImage:[myImage CGImage] scale:2.0 orientation:UIImageOrientationLeft];
