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);
}
