在解析ios中更新安装表中的设备令牌 [英] Update device token in installation table in parse ios

问题描述

我想使用iOS在解析时更新安装表中的设备令牌. 要保存设备令牌，我做了:

I want to update device token in installation table on parse using iOS. To save a device token I did:

PFInstallation *currentInstallation = [PFInstallation currentInstallation];
[currentInstallation setDeviceTokenFromData:(NSData*)[AppHelper userDefaultsForKey:@"token"]];
[currentInstallation setObject:[PFUser currentUser].objectId forKey:@"user"];
NSArray *channels = [NSArray arrayWithObjects:@"AnyString",nil];
currentInstallation.channels=channels;
[currentInstallation saveInBackground];

我想更新此设备令牌.我知道要更新令牌，我必须使用rest API，即 https://api.parse.com/1/installations .如何更新该行，因为我也没有安装ID.

I want to update this device token. I know to update token I have to use rest API i.e. https://api.parse.com/1/installations. How to update the row as I also don't have installation id.

请提供正确的语法.

推荐答案

在AppDelegate的didRegisterForRemoteNotificationsWithDeviceToken方法中编写以下代码.

Write below code in didRegisterForRemoteNotificationsWithDeviceToken method in AppDelegate .

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    PFInstallation *currnentInstallation = [PFInstallation currentInstallation];
    [currnentInstallation setDeviceTokenFromData:deviceToken];
    [currnentInstallation saveInBackground];
}

对于频道中的注册用户，请在登录屏幕中使用以下代码

For Register user in channels use below code in Login Screen

PFInstallation *currentInstallation = [PFInstallation currentInstallation];
if ([PFUser currentUser].objectId)
{
    currentInstallation[@"user"] = [PFUser currentUser];

    currentInstallation.channels = @[[NSString stringWithFormat:@"user_%@",[PFUser currentUser].objectId]];
    NSLog(@"Saving Installation channel = %@",currentInstallation.channels);

    [currentInstallation saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error)
    {
           NSLog(@"Current installation updated: Error: %@",error);
    }];
}
