【问题描述】:
我想为一周中的选定日期设置闹钟。
可能是工作日(周一、周二、周三、周四或周五)、周末(周六、周日)或每天。
如何使用本地通知来做到这一点?

检查this 和Local Notification Tutorial。还要检查这个Apple Document。

如果你有时间每天都必须触发通知,你应该这样做
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *components = [[NSDateComponents alloc] init];
for (NSMutableArray * arrDay in self.namaztimes) {
NSLog(@"Alarm Array: %@", arrDay);
int count=[arrDay count];
if(!count){
continue;
}
int day =0;
int month=0;
int year=0;
int hour =0;
int minutes=0;
// NSArray *arrDates=[[NSMutableArray alloc] initWithCapacity:1];
for ( int i=0;i<3;i++) {
NSString * dayTime=[arrDay objectAtIndex:i ];
if (i==0) {
day = [dayTime intValue];
}else if(i==1){
month = [dayTime intValue];
}else if(i==2){
year = [dayTime intValue];
}
}
for ( int i=3;i<count;i++) {
NSString * dayTime=[arrDay objectAtIndex:i ];
hour = [[dayTime substringToIndex:2] intValue];
minutes = [[dayTime substringFromIndex:3] intValue];
[components setDay:day];
[components setMonth:month];
[components setYear:year];
[components setMinute:minutes];
[components setHour:hour];
NSDate *myNewDate = [calendar dateFromComponents:components];
[self scheduleNotificationForDate:myNewDate];
}
}
[components release];
[calendar release];
然后从这里连接到主通知触发方法[self scheduleNotificationForDate:myNewDate];
-(void) scheduleNotificationForDate: (NSDate*)date {
/* Here we cancel all previously scheduled notifications */
[[UIApplication sharedApplication] cancelAllLocalNotifications];
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = date;
NSLog(@"Notification will be shown on: %@ ",localNotification.fireDate);
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.alertBody = @"Your Notification Text"; //[NSString stringWithFormat:@"%@",date];
localNotification.alertAction = NSLocalizedString(@"View details", nil);
/* Here we set notification sound and badge on the app's icon "-1"
means that number indicator on the badge will be decreased by one
- so there will be no badge on the icon */
localNotification.repeatInterval = NSDayCalendarUnit;
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.applicationIconBadgeNumber = -1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}

我知道这个问题是很久以前提出的,我添加这个是因为它会对某些人有所帮助。
如果您想在选定日期通知,请关注此tutorial。会有帮助的。
