Question

大家好我一直在尝试开发一个可以在UIImageView中为图像设置动画的cydia，我认为我的代码都很好但是由于某些原因，应用程序每次执行任务时都会崩溃。我已经读到这可能是导致一次加载太多图像的原因，但我只是尝试加载2个小png图像，所以我不认为这可能是原因。请让我知道你的想法！

%hook UISaveToCameraRollActivity
-(void)performActivity {
%orig;
NSBundle *bundle = [[NSBundle alloc] initWithPath:kBundlePath];
NSString *imagePath = [bundle pathForResource:@"hand" ofType:@"png"];
NSString *imagePath1 = [bundle pathForResource:@"floppy" ofType:@"png"];
UIWindow *statusWindow = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen]
bounds]];
statusWindow.windowLevel = UIWindowLevelStatusBar;
statusWindow.hidden = NO;
statusWindow.backgroundColor = [UIColor colorWithWhite:0.0 alpha:0.7];
UIImageView *pic = [[UIImageView alloc] initWithFrame:CGRectMake (0, 0, 69, 69)];
pic.animationImages = [NSArray arrayWithObjects:
[UIImage imageNamed:@"hand.png"],
[UIImage imageNamed:@"floppy.png"], nil];
pic.animationDuration = 1.0f;
[pic startAnimating];
pic.animationRepeatCount = 0;
[pic release];
pic.center = statusWindow.center;
pic.image = [UIImage imageWithContentsOfFile:imagePath];
pic.image = [UIImage imageWithContentsOfFile:imagePath1];
[statusWindow addSubview:pic];
[statusWindow makeKeyAndVisible];

}
%end

移动：

[pic release];

到你方法的结尾。一旦释放对象，就不应该与对象进行交互，这几乎是保证应用程序崩溃的有效方法。

如果你不想手动管理内存，你应该试试ARC：
