我已经阅读了一些关于如何使用 UILocalNotification
的指南。因此,自从我第一次尝试以来,我已经尝试过但没有成功。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接收通知:
- (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");
}
}
模拟器和设备上的一切都正常 - 当应用程序运行时,我收到预定的通知。但是我需要在应用程序未运行时接收通知,即当应用程序处于非事件状态时(按一次主页)
问题是,例如,如果我在按下按钮时安排我的通知,我会毫无问题地收到它,它会显示在通知中心,并且角标(Badge)会根据需要添加到我的应用程序图标上。但我只想在我的 AFNetworking
任务结束时收到通知。
我使用以下方法设置通知:
-(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);
}];
}
主要问题是此方法仅适用于 iOS 8.0 版本的模拟器,不适用于装有 iOS 7.1.1 的 iPhone 4 和装有 iOS 8.1.2 的 iPhone 5c 它也不起作用在 iOS 7.1 的模拟器上工作。
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收到通知,只有在我打开应用程序时才能收到通知(然后它会显示我在 AppDelegate.m
中设置的警报>)
我很乐意提供任何建议和帮助。
最佳答案
我看到您正在使用 Objective-C。考虑到这个问题是一年前提出的,您可能已经解决了这个问题,或者您现在正在使用 Swift 2.0。我遇到了同样的问题,我能够通过添加以下代码使用 Swift 2.0 解决它。
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
}
