关于iOS 13 获取Token

//获取DeviceToken成功
- (void)application:(UIApplication *)application
didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    //Xcode11打的包，iOS13获取Token有变化
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 13) {
        if (![deviceToken isKindOfClass:[NSData class]]) {
            //记录获取token失败的描述
            return;
        }
        const unsigned *tokenBytes = (const unsigned *)[deviceToken bytes];
        NSString *strToken = [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(@"deviceToken1:%@", strToken);
        return;
    } else {
        NSString *token = [NSString
                       stringWithFormat:@"%@",deviceToken];
        token = [token stringByReplacingOccurrencesOfString:@"<" withString:@""];
        token = [token stringByReplacingOccurrencesOfString:@">" withString:@""];
        token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
        NSLog(@"deviceToken2 is: %@", token);
    }
}

xcode 11下，你打印deviceToken 是这样的格式
,而实际我们需要获取的是这样的：xxxxxxxxxxxxxxxxxxxxx

处理

NSString *token = [NSString stringWithFormat:@"%@", deviceToken];
[self formatToken: token];
//去掉两边尖括号和中间空格
-(NSString *)formatToken:(NSString *)token {
    
    NSString *t = [[token substringWithRange:NSMakeRange(0, 72)] substringWithRange:NSMakeRange(1, 71)];
    t = [t stringByReplacingOccurrencesOfString:@" " withString:@""];
    return t;
}
