ios - Facebook SDK [FBAppEvents activateApp]随机崩溃

Question

我使用Facebook SDK v3.14。而且我发现方法[FBAppEvents activateApp]随机崩溃。因为[FBAppEvents activateApp]应该写在- (void)applicationDidBecomeActive:(UIApplication *)application中

我们的applicationDidBecomeActive应该每天调用约100M，约10天[FBAppEvents activateApp]崩溃约1000次。

崩溃日志在这里，任何人都可以帮助我，谢谢。

我已经下载了Facebook SDK源代码， [FBUtility attributionID]在这里:

+ (NSString *)attributionID {
    return [[UIPasteboard pasteboardWithName:@"fb_app_attribution" create:NO] string];
}

而且我找到了一些文档，没有文档告诉我 pasteboardWithName或 [UIPasteboard string]会导致崩溃

我已通过使用方法刷新来保护崩溃，以与自定义方法交换方法(+[FBUtility attributionID])

像这样的代码:

用Appdelegate.m

Method leftMethod = class_getClassMethod(NSClassFromString(@"FBUtility"), NSSelectorFromString(@"attributionID"));
Method rightMethod = class_getClassMethod(NSClassFromString(@"MyHackFBUtility"), NSSelectorFromString(@"attributionID"));
method_exchangeImplementations(leftMethod, rightMethod);

用 MyHackFBUtility.m

+ (NSString *)attributionID {

    return nil;
}

它可以运行几个月
