Ios 如何将我的设备令牌 (NSData) 转换为 NSString

发布于02月21日

我正在实施推送通知.我想将我的APNS令牌保存为字符串.

- (void)application:(UIApplication *)application
didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)newDeviceToken
{
    NSString *tokenString = [NSString stringWithUTF8String:[newDeviceToken bytes]]; //[[NSString alloc]initWithData:newDeviceToken encoding:NSUTF8StringEncoding];
    NSLog(@"%@", tokenString);
    NSLog(@"%@", newDeviceToken);
}

代码的第一行打印空.第二个命令打印令牌.如何将newDeviceToken作为NSString获取？

推荐答案

Note - This will not work when compiling with the iOS 13 or later SDK个

使用以下命令:

NSString * deviceTokenString = [[[[deviceToken description]
                         stringByReplacingOccurrencesOfString: @"<" withString: @""] 
                        stringByReplacingOccurrencesOfString: @">" withString: @""] 
                       stringByReplacingOccurrencesOfString: @" " withString: @""];
        
NSLog(@"The generated device token string is : %@",deviceTokenString);
