[英]Local notification repeatInterval
我的应用程序要显示学生时间表,我想添加一个本地通知repeatInterval
。
我打算为此使用开关按钮。
我尝试了这段代码,但现在无法正常工作:
-(IBAction)theSwitch:(id)sender{
if (switcher.on) {
NSCalendar *gregCalendar = [[NSCalendar alloc]initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *dateComponent = [gregCalendar components:NSYearCalendarUnit | NSWeekCalendarUnit fromDate:[NSDate date]];
[dateComponent setWeekday:3]; // For tuesday
[dateComponent setHour:13];
[dateComponent setMinute:41];
NSDate *fireDate = [gregCalendar dateFromComponents:dateComponent];
UILocalNotification *notification = [[UILocalNotification alloc]init];
[notification setAlertBody:@"ALARM!"];
[notification setFireDate:fireDate];
notification.repeatInterval = NSWeekCalendarUnit;
[notification setTimeZone:[NSTimeZone defaultTimeZone]];
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
}
else {UIApplication *app=[UIApplication sharedApplication];
[app scheduleLocalNotification:nil];
}
}
因此,我在此需要更多指导,以及有关如何实现此目标的一些建议。
如果您无法获得本地通知,请检查以下代码。
在AppDelegate.m文件中添加代码
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Handle launching from a notification
UILocalNotification *localNotification =
[launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (localNotification) {
NSLog(@"Recieved Notification %@", localNotification);
}
return YES;
}
添加方法来处理本地通知
- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notification {
// Handle the notificaton when the app is running
NSLog(@"Recieved Notification %@", notification);
}
