在iOS 10.2中從未調用didUpdatePushCredentials

Question

所以我打電話給：

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

它適用於ios 9、10.0.2和10.3。 didUpdatePushCredentials被調用，一切正常。 但是，對於ios 10.2，它永遠不會被調用，並且整個voip功能都無法使用。 您能告訴我這是怎么回事嗎？

PS：設置了IP語音和遠程通知功能。

請參閱ObjectiveC代碼以實現Pushkit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
