didUpdatePushCredentials在ios 10.2中永远不会被调用

Question

所以我打电话给：

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

它适用于ios 9,10.0.2和10.3。 didUpdatePushCredentials被调用，一切正常。但是，对于ios 10.2，它永远不会被调用，并且整个voip功能不起作用。你能告诉我它有什么问题吗？

PS：IP语音和远程通知功能已设置。

参考 ObjectiveC 代码进行推广套件集成

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
