WCSession activateSession exc_bad_access崩溃

我遇到WCSession activateSession的问题。 我在viewDidLoad方法中添加了此代码,并且在activateSession调用时崩溃了。 sendMessage也崩溃了。

if ([WCSession isSupported]) {
    [WCSession defaultSession].delegate = self;
    [[WCSession defaultSession] activateSession];
}

我虽然遇到了这个问题,但我调试它并在主线程上调用这些问题。

任何想法可能是什么问题?

这是崩溃日志:

我的应用程序中有Crittercism框架。一旦我在我的app delegate方法中注释了这一行,一切正常。

[Crittercism enableWithAppID:CRITTERCISM_APP_ID];

如果您在应用中使用Cirttercism,请务必在Crittercism之前写下此行[[WCSession defaultSession] activateSession]。 似乎他们有2.0支持,这就是冲突的原因。

您的代码必须在

之前调用
[Crittercism enableWithAppID:].
