Question

我有一个问题..我在我的xcode项目中得到了这个：

#import

int main(int argc, char *argv[]) {
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
int retVal = UIApplicationMain(argc, argv, nil, nil);  -> Thread 1: Signal SIGABRT
[pool release];
return retVal;

}

而且我真的不知道如何解决这个问题。请帮助我P !! ...

有时会出现此错误，因为已将IBOutlet连接到IB，然后删除了该ivar。检查所有IBOutlet是否正确连接。

然后检查您的viewcontroller的viewDidLoad，viewWillAppear或viewDidAppear方法中是否有任何错误代码。
