计算解雇方法

Question

我有一个下载图像的对象...当完成图像时，会调用一个方法finishLoad来保存这个图像...我在我的UIViewController中有一个这个对象的列表，我想知道有多少调用此方法的次数，当此count = 10时，我将调用另一种方法。我怎么能这样做？

@implementation DownloaderImage
{
    - (void)finishLoad {
//:: hide default image ::
[self setImage:nil];

//:: fade in in loaded picture ::
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
CGAffineTransform myTransform = CGAffineTransformMakeTranslation(0, 0);
[finalImage setTransform:myTransform];
finalImage.alpha = 1.0;

UIImage *scaledImage = [finalImage.image scaleToSize:CGSizeMake(320.0f, 345.0f)];
finalImage.image = scaledImage;

//:: fade out background picture ::
[backgroundImage setTransform:myTransform];
backgroundImage.alpha = 0.0;

[UIView commitAnimations];
 }
}

您可以使用静态变量：

static int myCount = 0;

- (void)finishLoad
{
    // ...
    myCount++;
    if (myCount == 10)
        // call your method
}
