我正在使用
Xcode 4.3.2,如何在每天早上6点设置本地通知“dateToFire”？
-(void)notification
{
UILocalNotification *localNotification = [[[UILocalNotification alloc] init] autorelease];
if (!localNotification)
return;
// Current date
NSDate *date = [NSDate date];
NSDate *dateToFire = //Everyday: 6AM;
// Set the fire date/time
[localNotification setFireDate:dateToFire];
[localNotification setTimeZone:[NSTimeZone defaultTimeZone]];
[localNotification setAlertBody:@"Notification" ];
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}
- (void)viewDidLoad
{
[super viewDidLoad];
[self notification];
}
解决方法
使用CalendarComponents将小时设置为6,并将localNotification.repeatInterval设置为NSDayCalendarUnit
NSCalendar *calendar = [NSCalendar currentCalendar]; // gets default calendar NSDateComponents *components = [calendar components:(NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit) fromDate:[NSDate date]]; // gets the year,month,day,hour and minutesfor today's date [components setHour:18]; [components setMinute:0]; localNotification.fireDate = [calendar dateFromComponents:components];
