似乎很长一段时间一切都很好,昨天没有任何可见的原因我开始出错
EXC_BAD_ACCESS (code = EXC_I386_GPFLT)
在模拟器的下一行(在真实设备上一切正常):
GPPSignIn *signIn = [GPPSignIn sharedInstance];
启用NSZombie消息后更改为
exc_breakpoint (code=exc_i386_bpt subcode=0x0)
。
这很奇怪,因为即使这行只是viewDidLoad中的一行而且它是应用程序中的第一个视图控制器,我一次又一次地得到错误(〜每3-4个应用程序启动)。我没有对应用配置进行任何更改。
我将不胜感激任何帮助。谢谢!

我可以看到。

追踪这是一个奇怪的问题。我只是在模拟器中遇到了[CFString retain]:
崩溃的同样问题(在设备上运行正常),但是当我试图在仪器中运行Zombies时,它永远不会显示僵尸。
经过大量搜索后,您的问题引导我使用backtrace命令查明Google+ SDK导致此问题。
虽然这只是一个解决方法,直到谷歌解决了这个问题,你可以让你的应用程序在模拟器上运行,将GPPSignIn
包装在预编译器指令中,检查你是否在模拟器中运行:
#if !(TARGET_IPHONE_SIMULATOR)
- (GPPSignIn *) googlePlusSession {
NSLog(@"Not running on simulator");
if(_googlePlusSession == nil) {
_googlePlusSession = [GPPSignIn sharedInstance];
_googlePlusSession.clientID = kGoogleClientId;
_googlePlusSession.scopes = [NSArray arrayWithObjects:kGTLAuthScopePlusLogin,nil];
_googlePlusSession.delegate = self;
[_googlePlusSession trySilentAuthentication];
}
return _googlePlusSession;
}
#endif
显然,在模拟器上运行时,这会破坏应用中的Google+功能,但在我的情况下,这比根本无法启动要好得多。希望这会有所帮助。
