Ios 错误:您必须初始化PFFacebookUtils
当我在我的应用程序中调用以下目标C代码时,我得到一个异常Ios 错误:您必须初始化PFFacebookUtils,ios,iphone,xcode,facebook,parse-platform,Ios,Iphone,Xcode,Facebook,Parse Platform,当我在我的应用程序中调用以下目标C代码时,我得到一个异常 [PFFacebookUtils logInInBackgroundWithReadPermissions:permissions block:^(PFUser *user, NSError *error) { if (!user) { NSLog(@"Uh oh. The user cancelled the Facebook login."); UIAlertView *alert =
[PFFacebookUtils logInInBackgroundWithReadPermissions:permissions block:^(PFUser *user, NSError *error) {
if (!user) {
NSLog(@"Uh oh. The user cancelled the Facebook login.");
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Login Failed"

otherButtonTitles:nil];
[alert show];
} else if (user.isNew) {
NSLog(@"User signed up and logged in through Facebook!");
[self performSegueWithIdentifier:@"logInSegue" sender:sender];
} else {
NSLog(@"User logged in through Facebook!");
[self performSegueWithIdentifier:@"logInSegue" sender:sender];
}
}];
由于未捕获的异常“NSInternalInconsistencyException”而终止应用程序,原因是:“您必须通过调用+initializeFacebookWithApplicationLaunchOptions来初始化PFFacebookUtils”
下面是用Swift编写的AppDelegate代码,我不太确定如何初始化Swift错误中的内容?我正在使用最新版本的Parse,并且在我的pod文件中,我有以下pod‘ParseFacebookUtilsV4’?你知道怎么解决这个问题吗
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool {
// Enable storing and querying data from Local Datastore.
// Remove this line if you don't want to use Local Datastore features or want to use cachePolicy.
Parse.enableLocalDatastore()
Parse.setApplicationId(appID, clientKey: clientKey)
PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)
let granted: Bool = AppDelegate.IsNotificationPermissionGranted()
if (granted) {
AppDelegate.registerNotification()
}
//code block from starter project
PFUser.enableAutomaticUser()
let defaultACL = PFACL();
// If you would like all objects to be private by default, remove this line.
//defaultACL.setPublicReadAccess(true)
PFACL.setDefaultACL(defaultACL, withAccessForCurrentUser:true)
if application.applicationState != UIApplicationState.Background {
// Track an app open here if we launch with a push, unless
// "content_available" was used to trigger a background push (introduced in iOS 7).
// In that case, we skip tracking here to avoid double counting the app-open.
let preBackgroundPush = !application.respondsToSelector("backgroundRefreshStatus")
let oldPushHandlerOnly = !self.respondsToSelector("application:didReceiveRemoteNotification:fetchCompletionHandler:")
var noPushPayload = false;
if let options = launchOptions {
noPushPayload = options[UIApplicationLaunchOptionsRemoteNotificationKey] != nil;
}
if (preBackgroundPush || oldPushHandlerOnly || noPushPayload) {
PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)
}
}
return true
}
将以下代码添加到didFinishLaunchingWithOptions方法中的AppDelegate类
PFFacebookUtils.initializeFacebookWithApplicationLaunchOptions(launchOptions)
请注意,您可能需要先导入ParseFacebookUtilsV4。谢谢您,Ivan,我已经尝试过了,但后来删除了那行代码,因为它无法识别PFFaceBookUtil,因为我忘了导入ParseFacebookUtilsV4
