我已经将iPhone 6 plus更新到iOS 9测试版,并试图执行Facebook登录,但每次使用Facebook登录表单呈现UIWebView.

我有Facebook sdk

FB_IOS_SDK_VERSION_STRING @"3.24.0"
FB_IOS_SDK_TARGET_PLATFORM_VERSION @"v2.2"

我正在使用以下方法来执行Facebook登录

    NSArray *permissions = @[@"email",@"user_birthday",@"public_profile"];


     FBSessionStateHandler completionHandler = ^(FBSession *session, FBSessionState status, NSError *error) {
         [self sessionStateChanged:session state:status error:error];
     };

     if ([FBSession activeSession].state == FBSessionStateCreatedTokenLoaded) {
     // we have a cached token, so open the session
         [[FBSession activeSession]openWithBehavior:FBSessionLoginBehaviorUseSystemAccountIfPresent
                                 fromViewController:nil
                                  completionHandler:completionHandler];
     } else {

     [self clearAllUserInfo];
    [[NSURLCache sharedURLCache] removeAllCachedResponses];

     // create a new facebook session
     FBSession *fbSession = [[FBSession alloc] initWithPermissions:permissions];
     [FBSession setActiveSession:fbSession];
     [fbSession openWithBehavior:FBSessionLoginBehaviorUseSystemAccountIfPresent
              fromViewController:nil
               completionHandler:completionHandler];
     }

我在plist文件下面进行了以下设置

    <key>LSApplicationQueriesSchemes</key>
    <array> …

甚至我的应用程序都在后台注册位置更新.

在我的代码中:

self.locationManager.desiredAccuracy = kCLLocationAccuracyThreeKilometers;
self.locationManager.distanceFilter = 2500;

我没有搬到任何地方.因此,在控制台日志中完成15分钟后,我收到此消息"位置图标现在应处于"非活动状态".从这一点开始,我的应用程序不在后台运行.

它只在iPhone 5中发生.

@更新

这是我的代码

self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
[self.locationManager setPurpose:@"Enable Location service for \"My App\" to track your"];
self.locationManager.desiredAccuracy = kCLLocationAccuracyThreeKilometers;

/* Notify changes when device has moved x meters.
 * Default value is kCLDistanceFilterNone: all movements are reported.
 */
self.locationManager.distanceFilter = 2500;
[self.locationManager startUpdatingLocation];

在阅读了一些关于它的其他猜测后,我尝试过:
在ViewController.m上

DelegateScrollView ScrollView;

-(void)viewDidLoad
{

    [super viewDidLoad];
    ScrollView = [[DelegateScrollView alloc] initWithFrame:CGRectMake(0,-   self.view.frame.size.height, self.view.frame.size.width, self.view.frame.size.height)];
    ScrollView.delegate = ScrollView;
    ScrollView.scrollEnabled = YES;
    ScrollView.backgroundColor = [UIColor blackColor ];
    ScrollView.maximumZoomScale = 5.0f;
    ScrollView.minimumZoomScale = 1.0f;
    [self.view addSubview:ScrollView];
    [ScrollView setZoomScale:2 animated:YES];

     }

DelegateScrollView.h:

@interface ChildDelegateScrollView : UIScrollView <UIScrollViewDelegate>

@end 

并且zoom也永远不会发生我也在ViewController.h中试过这个:@interface ViewController : UIViewController <UIScrollViewDelegate> 然后像这样设置委托ScrollView.delegate = self;而不起作用,如何正确设置ScrollView的委托？
