ios - GPPSignIn 共享实例 -> EXC_BAD_ACCESS(代码 = EXC_I386_GPFLT)

似乎很长一段时间一切都很好,昨天没有任何明显的原因我开始出错

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,因为即使这一行在 viewDidLoad 中只有一行,并且它是应用程序中的第一个 View Controller ,我也会一次又一次地出错(~每 3-4 个应用程序启动)。我没有对应用配置进行任何更改。

如有任何帮助,我将不胜感激。谢谢!

更新:libobjc.A.dylib 发生错误

如我所见。

最佳答案

这是一个需要追踪的奇怪问题。 [CFString retain]: 我一直遇到同样的问题,只在模拟器中崩溃(在设备上运行良好),但是当我尝试在 Instruments 中运行 Zombies 时,它永远不会显示僵尸。

CFString retain issue on iOS simulator

经过大量搜索后,您的问题让我使用 backtrace 命令查明问题是由 Google+ SDK 引起的。

虽然这只是 Google 解决问题之前的一种解决方法,但您可以通过将 GPPSignIn 包装在预编译器指令中来检查您是否在模拟器中运行,从而让您的应用程序在模拟器上运行:

#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,当在模拟器上运行时,这会搞砸您的应用程序中的 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。
