UILocalNotification計劃每天直到日期

Question

我已經安排每日通知，與此代碼：

NSCalendar *calendar = [NSCalendar currentCalendar]; 
NSDateComponents *components = [[NSDateComponents alloc] init]; 
[components setDay:7]; 
[components setMonth:3]; 
[components setYear:2014]; 
[components setHour:9]; 
NSInteger minute = arc4random() % 59; 
[components setMinute:minute]; 
[components setSecond:0]; 
[calendar setTimeZone:[NSTimeZone defaultTimeZone]]; 
NSDate *dateToFire = [calendar dateFromComponents:components]; 

UILocalNotification *localNotification = [[UILocalNotification alloc] init]; 
localNotification.userInfo = @{@"uid": DailyNotificationUid}; 
localNotification.fireDate= dateToFire; 
localNotification.timeZone = [NSTimeZone defaultTimeZone]; 

NSString *body = NSLocalizedString(@"Local Notification Alert Body", nil); 
localNotification.alertBody = body; 
localNotification.alertAction = NSLocalizedString(@"Local Notification Alert Action", nil); 
localNotification.soundName = UILocalNotificationDefaultSoundName; 
localNotification.applicationIconBadgeNumber = 1; 
localNotification.repeatInterval = NSCalendarUnitDay; 

[[UIApplication sharedApplication] scheduleLocalNotification:localNotification]; 

但我錯過到期日期。通知應在聖誕節結束，而用戶不必啓動應用程序。這可能嗎？

您不能在UILocalNotification中指定到期日期。相反，你需要創建UILocalNotification直到聖誕節。但是也存在64 UILocalNotification的限制。
