iOS 13 DeviceToken获取发生变化

问题描述：

iOS 13 通过[deviceToken description]获取到的内容已经变了，这段代码运行在 iOS 13 上已经无法获取到准确的DeviceToken字符串了，

NSString *dt = [deviceToken description]; dt = [dt stringByReplacingOccurrencesOfString: @"<" withString: @""]; dt = [dt stringByReplacingOccurrencesOfString: @">" withString: @""]; dt = [dt stringByReplacingOccurrencesOfString: @" " withString: @""]; 

解决方案：

(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { if (![deviceToken isKindOfClass:[NSData class]]) return; const unsigned *tokenBytes = [deviceToken bytes]; NSString *hexToken = [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(@"deviceToken:%@",hexToken); }
