本文详细介绍了从MBProgressHUD中摘取的释放代码段，包括属性的释放和非ARC环境下的保留方式，确保资源的有效管理和内存泄漏的预防。

从MBProgressHUD里面摘出来的

#if !__has_feature(objc_arc)
- (void)dealloc {
    [indicator release];
    [label release];
    [detailsLabel release];
    [labelText release];
    [detailsLabelText release];
	[graceTimer release];
	[minShowTimer release];
	[showStarted release];
	[customView release];
    [super dealloc];
}
#endif

#if __has_feature(objc_arc_weak)
@property (weak) id<MBProgressHUDDelegate> delegate;
#elif __has_feature(objc_arc)
@property (unsafe_unretained) id<MBProgressHUDDelegate> delegate;
#else
@property (assign) id<MBProgressHUDDelegate> delegate;
#endif
