如何獲取推送通知的iPhone設備令牌？

Question

我正在嘗試在我的應用程序中使用遠程推送通知，我試圖在我的應用程序中進行此測試，但在我開始點擊“允許”后我無法重置警報彈出窗口。

所以我的問題是：

即使用戶在警告彈出窗口中點擊“不允許”，我仍然可以獲得設備令牌嗎？

Answer 1

使用appDelegate方法

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
    {
        self.mDeviceToken = deviceToken;

        //Removing the brackets from the device token
        NSString *tokenString = [[deviceToken description] stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];

        NSLog(@"Push Notification tokenstring is %@",tokenString);

    }   

以防萬一

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{

    NSString* s=[[NSString alloc] initWithFormat:@"%@",error];
    UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"Error" message:s delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alert show];
    [alert release];
    [s release];
// lert because your device will not show log
}

Answer 2

使用以下代理方法...

-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{

    NSLog(@">>%@",deviceToken);// this will give  you token
}

-(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error{

    NSLog(@">>%@",error); // this will gave you error msg with description.

}

希望這個能對您有所幫助..
