Question

我是Objective-C语言的新手。我需要实现的只是我的应用程序上的推送通知位。我使用javapns库在XCode 6和Java服务器端编写了客户端。现在，当服务器设法发送通知（我收到确认消息）时，我的设备上没有收到任何内容，无论是应用程序处于活动状态还是在后台运行。

有人可以指导我朝正确的方向前进吗？谢谢！

#import "AppDelegate.h"

@interface AppDelegate ()

@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert |UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
[[UIApplication sharedApplication] registerForRemoteNotifications];

return YES;
}

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)newDeviceToken{
//Store the Device Token
NSLog(@"%@", newDeviceToken);
}

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error{
NSLog(@"Failed to register with error: %@", error);
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
NSLog(@"Push received: %@", userInfo);
}

服务器端：

public class PushServer {
public static void main(String[] args) {
    try {
        BasicConfigurator.configure();
        Push.alert("Message!", "***.p12", "***", false,
                "92ab*************91af4");
    } catch (CommunicationException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (KeystoreException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

}

这是我尝试发送通知时收到的输出：

感谢任何帮助。

您偶然会使用Xcode 7构建并定位到iOS 9吗？

如果是这样，您可能会遇到新的安全默认设置，需要安全地访问网址，如下所述：

Disabling ATS for an in-app browser in iOS 9?

此外，您似乎将旧方法与新方法混合在一起。

registerUserNotificationSettings是一个取代了registerForRemoteNotificationTypes的iOS 8方法。

所以，只使用前者，看起来你只针对iOS 8及更高版本。

但是你使用didReceiveRemoteNotification：这是该方法的旧版本，对应于registerForRemoteNotificationTypes。但是，由于您使用的是较新的版本，因此您应该使用它 didReceiveRemoteNotification：fetchCompletionHandler

您需要将NSData转换为字符串，并通过在您的方法中实施以下更改来获取实际的设备令牌。

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    NSString *myToken = [[[[deviceToken description] stringByReplacingOccurrencesOfString: @"<" withString: @""]
                              stringByReplacingOccurrencesOfString: @">" withString: @""]
                             stringByReplacingOccurrencesOfString: @" " withString: @""];
    // *** Now user `myToken` to send notification ***
    NSLog(@"%@",myToken);
}

除此之外，您还需要确保运行的应用程序具有相同的临时配置文件（开发人员/分发），用于在服务器端发送推送通知。两者都应该是一样的。我希望你能清楚。
