推送通知委托方法问题 [英] Push notification delegate method issue

问题描述

我是 Objective C 的新手.在我的应用程序中，我需要实现推送通知，我已经创建了新的应用程序 ID，并且还创建了新的配置文件.我已经完成了这个 link

我已经在我的 appDelegate .m 文件中声明了这个委托函数.

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {NSString *deviceTokens = [[deviceToken description] stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];deviceTokens = [deviceTokens stringByReplacingOccurrencesOfString:@" " withString:@""];NSLog(@"注册的设备令牌%@", deviceTokens);self.deviceToken = deviceTokens;}- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err {NSString *str = [NSString stringWithFormat: @"Error: %@", err];NSLog(@"字符串 %@",str);}- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {for(userInfo 中的 id 键){NSLog(@"key: %@, value: %@", key, [userInfo objectForKey:key]);}}

但是这个委托函数没有被调用.请帮我解决这个问题.

解决方案

在你的 AppDelegated didfinishLaunching with options 中写下一行

[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];

I am new to Objective C. In my app i need to implement push notification, i have created new app ID and i have created new provisioning profile also. i have finished all the steps mentioned in this link

i have declared this delegate function in my appDelegate .m file.

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

        NSString *deviceTokens = [[deviceToken description] stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];
        deviceTokens = [deviceTokens stringByReplacingOccurrencesOfString:@" " withString:@""];
        NSLog(@"registered device token %@", deviceTokens);
        self.deviceToken = deviceTokens; 
}

- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err { 

    NSString *str = [NSString stringWithFormat: @"Error: %@", err];
    NSLog(@"String %@",str);    

}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {

    for (id key in userInfo) {
        NSLog(@"key: %@, value: %@", key, [userInfo objectForKey:key]);
    }    

}

But this delegate functions are not called. please help me to fix this issue.

解决方案

In your AppDelegated didfinishLaunching with options write the following line

[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];
