didUpdatePushCredentials從未被稱爲在IOS 10.2

Question

因此，我呼籲：

self.pushRegistry.desiredPushTypes = [NSSet setWithObject:PKPushTypeVoIP];

它適用於iOS 9，10.0.2和10.3。 didUpdatePushCredentials被調用並且一切正常。然而，對於ios 10.2，它永遠不會被調用，並且整個voip功能不起作用。你能不能告訴它有什麼問題？

PS：設置IP語音和遠程通知功能。

參考的ObjectiveC代碼pushkit整合

AppDelegate.h

#import <UIKit/UIKit.h> 
#import <PushKit/PushKit.h> 

@interface AppDelegate : UIResponder <UIApplicationDelegate,PKPushRegistryDelegate> 
{ 
    PKPushRegistry *pushRegistry; 
} 

@property (strong, nonatomic) UIWindow *window; 

@end 

AppDelegate.m

#import "AppDelegate.h" 

@interface AppDelegate() 

@end 

@implementation AppDelegate 


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 


    pushRegistry = [[PKPushRegistry alloc] initWithQueue:dispatch_get_main_queue()]; 
    pushRegistry.delegate = self; 
    pushRegistry.desiredPushTypes = [NSSet setWithObject:PKPushTypeVoIP]; 

    return YES; 
} 

#define PushKit Delegate Methods 

- (void)pushRegistry:(PKPushRegistry *)registry didUpdatePushCredentials:(PKPushCredentials *)credentials forType:(NSString *)type{ 
    if([credentials.token length] == 0) { 
     NSLog(@"voip token NULL"); 
     return; 
    } 

    NSLog(@"PushCredentials: %@", credentials.token); 
} 

- (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload forType:(NSString *)type 
{ 
    NSLog(@"didReceiveIncomingPushWithPayload"); 
} 
@end
