推送通知警告？

发布于 2024-10-17 10:45:27 字数 674 浏览 3 评论 0原文

我正在我的应用程序中处理推送通知。但我收到这个警告：不兼容的 Objective-C 类型分配“struct NSString *”，期望“struct NSData *”，

其收到警告的代码是：

  - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
// Here you send the deviceToken to your server.. 
deviceToken = [[[[deviceToken description]
                 stringByReplacingOccurrencesOfString: @"<" withString: @""]
                stringByReplacingOccurrencesOfString: @">" withString: @""]
               stringByReplacingOccurrencesOfString: @" " withString: @""];

NSLog(@"Device Token: %@",deviceToken);
}

任何人都可以告诉我为什么收到该警告。

谢谢

I am working with push notifications in my app. but I am getting this warning:
Incompatible Objective-C types assigning 'struct NSString *', expected 'struct NSData *'

the code where its getting warning is:

  - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
// Here you send the deviceToken to your server.. 
deviceToken = [[[[deviceToken description]
                 stringByReplacingOccurrencesOfString: @"<" withString: @""]
                stringByReplacingOccurrencesOfString: @">" withString: @""]
               stringByReplacingOccurrencesOfString: @" " withString: @""];

为什么不创建一个名为 deviceTokenStr 的单独 NSString 因为 deviceToken 本身是一个 NSData 对象并且它导致了错误

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

    NSLog(@"Device Token: %@",deviceTokenStr);

Why don't you create a separate NSString called deviceTokenStr as deviceToken itself is an NSData object and it is causing the error

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

    NSLog(@"Device Token: %@",deviceTokenStr);
