我已经阅读了一些如何使用UILocalNotification的指南.所以自从我第一次尝试以来,我已经尝试过并且没有成功.要在AppDelegate.m中注册通知,我使用:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
...
//if it is iOS 8
if ([application respondsToSelector:@selector(registerUserNotificationSettings:)])
{
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge|UIUserNotificationTypeAlert|UIUserNotificationTypeSound) categories:nil];
[application registerUserNotificationSettings:settings];
}
else // if iOS 7
{
UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
[application registerForRemoteNotificationTypes:myTypes];
}
UILocalNotification *locationNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (locationNotification) {
// Set icon badge number to zero
application.applicationIconBadgeNumber = 0;
}
return YES;
}

并在应用程序运行时收到通知:
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
NSLog(@"notification recieved %@",notification.alertBody);
// NSLog(@"notification userinfo %@",notification.userInfo);
UIApplicationState state = [application applicationState];
if (state == UIApplicationStateActive) {
NSLog(@"notification fired in foreground");
UIAlertView *message = [[UIAlertView alloc] initWithTitle:@"Notification!"
message:notification.alertBody
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[message show];
} else if (state == UIApplicationStateInactive){
NSLog(@"notification fired in inactive");
} else if (state == UIApplicationStateBackground){
NSLog(@"notification fired in background");
}
}

一切都在模拟器和设备上都可以 - 当应用程序运行时,我得到了我的重复通知.但我需要在应用程序未运行时收到通知,即应用程序处于非活动状态时(主页按下一次)
问题是,如果我按下按钮按下我的通知,例如,我会毫无问题地得到它,它将显示在通知中心,徽章将添加到我想要的应用程序图标上.但我希望只在我的AFNetworking任务结束时收到通知.
要设置通知,我使用以下方法:
-(void)getProgress{
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSString *token = [defaults objectForKey:@"token"];
NSString *header = [NSString stringWithFormat:@"Bearer %@",token];
NSDictionary *params = @{@"lang": @"en",@"project":projId};
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager.requestSerializer setValue:header forHTTPHeaderField:@"Authorization"];
[manager POST:@"http://example.com/api/get-progress" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
if ([[responseObject objectForKey:@"result"]isEqualToString:@"success"]){
progCreate = [responseObject objectForKey:@"progress"];
if ([progCreate intValue]==100){
//shedule notification for immediately showing
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:0];
localNotification.alertBody = [NSString stringWithFormat:@"Notification text!"];
localNotification.alertAction = @"Show";
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
[localNotification setSoundName:UILocalNotificationDefaultSoundName];
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
// [[UIApplication sharedApplication]presentLocalNotificationNow:localNotification]; the same result as above
}
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];
NSLog(@"Error: %@", error);
}];
}

主要问题是这种方法仅适用于iOS版本8.0的模拟器,并且不适用于iOS 7.1.1的iPhone 4和iOS 8.1的iPhone 5c,它也不适用于iOS 7.1的模拟器.在使用iOS 7.1+的真实设备和模拟器上,我从来没有注意到在后台接收通知,只有在我打开应用程序时才能获得它(然后它在我设置时显示警报AppDelegate.m)我会很高兴任何建议和任何帮助.
我看到你正在使用Objective-C.考虑到一年前问过这个问题,你可能要么想出这个问题,要么你现在正在使用Swift 2.0.我有同样的问题,我可以通过添加以下代码解决它与Swift 2.0.
AppDelegate.swift:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil))
application.beginBackgroundTaskWithName("showNotification", expirationHandler: nil)
return true
}
