项目中一个UIViewController内使用异步线程，异步线程未执行完时pop退出此画面，程序crash。控制台打出错误如下：
Tried to obtain the web lock from a thread other than the main thread...
经调查，发现是由于UIViewController的release方法没有在主线程中调用造成的crash，修改方法如下：
- (oneway void) release {
if (![NSThread isMainThread]) {
[self performSelectorOnMainThread:@selector(release) withObject:nil waitUntilDone:NO];
} else {
[super release];
}
}
添加以上代码到UIViewController中，当不在主线程中执行release时，强行回到主线程中执行。
