如何将我的设备令牌（NSData）转换为NSString？ [英] How can I convert my device token (NSData) into an NSString?

问题描述

我正在实施推送通知。我想将我的APNS令牌保存为字符串。

I am implementing push notifications. I'd like to save my APNS Token as a String.

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

第一行代码打印null。第二个打印令牌。如何将我的newDeviceToken作为NSString？

The first line of code prints null. the second prints the token. How can I get my newDeviceToken as an NSString?

推荐答案

使用：

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

NSLog(@"The generated device token string is : %@",deviceTokenString);
