ios - Twitter 登录 - App Delegate 中的线程 1 Sigabrt 错误和应用程序崩溃

Question

我正在尝试创建一个简单的解析日志，将 Twitter 和 Facebook 集成为 iOS9 中的登录选项。 Facebook 登录正常，但 Twitter 登录一直崩溃，不知道为什么？崩溃导致 AppDelegate.swift 说有一个 Sigabrt error "thread 1 signal sigabrt"

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.
    Parse.setApplicationId("<MY ID>", clientKey:"<MY CLIENT KEY>")
    PFTwitterUtils.initializeWithConsumerKey("<CONSUMER KEY>", consumerSecret:"<CONSUMER SECRET>")
    PFFacebookUtils.initializeFacebookWithApplicationLaunchOptions(launchOptions);

Answer 1

当我在我的应用程序中实现多个 url 方案时，我遇到了同样的问题。 崩溃的原因是 Spotify 正在处理 application(_ app: UIApplication, open url: URL) 中的 twitter url schemes

我能够通过检查即将到来的 url 方案的类型来解决问题。 对于我使用的推特

if url.scheme != nil && url.scheme!.hasPrefix("twitterkit"){ //Twitter SDK
        return TWTRTwitter.sharedInstance().application(app, open: url, options: options)
}  else{ //Other SDK's  }
