前提：使用的iOS16系统测试
1.需要引入PushKit和CallKit，两个都需要
#import <PushKit/PushKit.h>
#import <CallKit/CallKit.h>
如果没有用CallKit，会存在推送成功，但是手机上app不在前台收不到回调的情况（后台或者杀死app情况，不会唤起app）
2.注册pushkit
PKPushRegistry *pushRegistry = [[PKPushRegistry alloc] initWithQueue:dispatch_get_main_queue()];
pushRegistry.delegate=self;
pushRegistry.desiredPushTypes = [NSSet setWithObject:PKPushTypeVoIP];
3.上报token
#pragma mark PKPushRegistryDelegate
- (void)pushRegistry:(PKPushRegistry*)registrydidUpdatePushCredentials:(PKPushCredentials*)credentialsforType:(NSString*)type
{
if ([type isEqualToString:PKPushTypeVoIP])
{
constunsigned*tokenBytes = (constunsigned*)[credentials.tokenbytes];
NSString *result = [NSString stringWithFormat:@"%08x%08x%08x%08x%08x%08x%08x%08x",
ntohl(tokenBytes[0]),ntohl(tokenBytes[1]),
ntohl(tokenBytes[2]),ntohl(tokenBytes[3]),
ntohl(tokenBytes[4]),ntohl(tokenBytes[5]),
ntohl(tokenBytes[6]),ntohl(tokenBytes[7])];
NSLog(@"pk token str = [%@]",result);
}
}
4.收到pushkit推送触发的回调
- (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload forType:(NSString *)type withCompletionHandler:(nonnull void (^)(void))completion
{
NSLog(@"receive payload %@ type %@", payload.dictionaryPayload,type);
NSNumber*badge = payload.dictionaryPayload[@"aps"][@"badge"];
badge =@99;
if([badgeisKindOfClass:[NSNumberclass]])
{
[UIApplication sharedApplication].applicationIconBadgeNumber = [badge integerValue];
}
CXHandle *callHandle = [[CXHandle alloc] initWithType:CXHandleTypePhoneNumber value:@"123"];
CXCallUpdate*callUpdate = [[CXCallUpdatealloc]init];
callUpdate.remoteHandle= callHandle;
callUpdate.localizedCallerName=@"John Smith";
callUpdate.supportsHolding=NO;
callUpdate.supportsGrouping=NO;
callUpdate.supportsUngrouping=NO;
callUpdate.hasVideo=NO;
CXProviderConfiguration *config = [[CXProviderConfiguration alloc] initWithLocalizedName:@"My App"];
config.maximumCallsPerCallGroup = 1;
config.supportsVideo=NO;
CXProvider*provider = [[CXProvideralloc]initWithConfiguration:config];
[providerreportNewIncomingCallWithUUID:[NSUUID UUID] update:callUpdate completion:^(NSError * _Nullable error) {
completion();
}];
}
这个里面要处理使用CallKit来reportNewIncomingCallWithUUID。不然在后台虽然走了这个回调，会crash，Killing app because it never posted an incoming call to the system after receiving a PushKit VoIP push。表示您的应用程序在接收到VoIP推送后未能将来电事件通知系统导致crash。
5.要添加xcode项目配置
