使用转换时的内存泄漏

Question

当使用这个转换超过7-8次时，我得到了内存泄漏和崩溃：

-(IBAction)pan1:(id)sender{

    CATransition *transition = [CATransition animation];
    transition.duration = 0.50;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    NSString *types[4] = {kCATransitionFade};
    int rnd = random() % 4;
    transition.type = types[rnd];
    transitioning = YES;
    transition.delegate = self;
    UIImage *image4 = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"pan_01_cross_0.png" ofType:nil]];
    pan_cross_0 = [[UIImageView alloc] initWithImage:image4];
    [panView.layer addAnimation:transition forKey:nil];
    [panView addSubview:pan_cross_0]; 
}

Answer 1

如果您多次运行pan方法，我可以在pan_cross_0中看到至少1个内存泄漏。

pan_cross_0 = [[UIImageView alloc] initWithImage:image4];

您将新的图像视图分配到pan_cross_0中，但没有从上次释放它。我不确定是什么导致了崩溃。我至少需要更多细节
