WCSession激活Session exc_bad_access崩溃

Question

我的WCSession activateSession有问题。我在viewDidLoad方法中添加了这段代码，它在activateSession调用时崩溃了。sendMessage也崩溃了。

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

我认为这个问题是线程的问题，但我在主线程上调试它和这些调用。

知道问题出在哪里吗？

这是崩溃日志：

Answer 1

我的应用程序中有Critterism框架。一旦我在我的应用程序委托方法中评论了这一行，一切都很好。

[Crittercism enableWithAppID:CRITTERCISM_APP_ID];

如果你在应用程序中使用Circtterism，请确保在Critterism之前写下这行[[WCSession defaultSession] activateSession]。似乎他们支持watch2.0，这就是冲突的原因。

Answer 2

您的代码必须在之前调用

[Crittercism enableWithAppID:].
