我在AppDelegate.swift文件中发现此错误,它出现在AppDidFinishLaunchingWithOptions函数中。它正在提高来自Parse框架的一行代码的错误。
PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)
错误出现在launchOptions
参数上。我将发布整个函数以表明它应该是正确的。此外,当我注释掉代码行时,错误消失了,但我仍然真的希望能够使用该功能并跟踪分析。这是整个功能:
func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: AnyObject!) -> Bool
{
// Override point for customization after app launches
Parse.setApplicationId("removed on purpose", clientKey: "removed on purpose")
PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)
PFFacebookUtils.initializeFacebook()
return true
}
我似乎无法找到与此错误相关的任何内容。如果有人有一些见解我会非常感激!

自Xcode 6 beta 7起,当您想要致电application:didFinishLaunchingWithOptions:
时,您必须更换:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
/* ... */
}
使用以下代码:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
/* ... */
}
此方法的最后一个参数不再是NSDictionary,而是类型为[NSObject: AnyObject]?
的词典。因此,您必须更新代码(包括trackAppOpenedWithLaunchOptions:
参数类型)。

launchOptions
参数应声明为NSDictionary!
而不是AnyObject!
:
func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {
// ...
}
