Twitter登录-线程1应用程序委派和应用程序崩溃中的Sigabrt错误

Question

我正在尝试创建一个简单的解析日志，该日志集成了Twitter和Facebook作为iOS9中的登录选项。Facebook登录工作正常，但Twitter登录一直崩溃，不知道为什么？崩溃导致AppDelegate.swift表示存在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

当我在应用程序中实现多个url方案时，我也面临着同样的问题。崩溃的原因是Spotify正在处理应用程序中的推特url方案（_app:UIApplication，open url:url）

我能够通过检查即将到来的url方案的类型来解决这个问题。对于twitter，我使用

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