==============非主线程
[self performSelectorOnMainThread:@selector(onResp*****eInMainThread) withObject:nil waitUntilDone:YES];============= 主线程-(void)onResp*****eInMainThread{ [waitingBackView removeFromSuperview]; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"title" message:@"message !" delegate:nil cancelButtonTitle:@"Done" otherButtonTitles:nil]; [alert show]; [alert release];
只有UIAlertView才会引起这个错误吗?我的程序中没有用到UIAlertView的接口,而且在界面更新的时候也没有涉及到多线程,但还是出现了这个错误提示.....
我现在一个app,全屏幕的起始界面,然后在controller里设置 [[UIApplication sharedApplication] setStatusBarHidden:NO]; 显示状态栏,就会有这个情况
