iPhone - UILocalNotification作爲鬧鐘

Question

即使我的iPhone應用程序在後臺，我如何使用UILocalNotification在每天晚上8點顯示我的阿拉姆？

Answer 1

設置fireDate至晚上8時，設置repeatInterval到NSDayCalendarUnit和安排與[[UIApplication sharedApplication] scheduleLocalNotification: myNotification];

Answer 2

dasdom答案警告是正確的。只是想增加它，如果您的設備處於靜音模式，鬧鐘不會發出聲音。這是Apple對UILocalNotification的限制。

Answer 3

UILocalNotification *localNotification =[[UILocalNotification alloc]init]; 

NSCalendar *calendar=[NSCalendar currentCalendar]; 
    [calendar setTimeZone:[NSTimeZone defaultTimeZone]]; 

    unsigned currentFlag=NSDayCalendarUnit|NSMonthCalendarUnit|NSYearCalendarUnit|NSWeekdayCalendarUnit; 

    NSDateComponents *comp=[calendar components:currentFlag fromDate:[NSDate date]]; 

    comp.hour=8; 
    comp.minute=0; 
    comp.second=0; 

    NSDate *date=[[calendar dateFromComponents:comp]dateByAddingTimeInterval:0]; 

    if (localNotification==nil) { 
     return; 
    } 

    localNotification.fireDate=date; 
    localNotification.timeZone=[NSTimeZone defaultTimeZone]; 
    localNotification.repeatCalendar=[NSCalendar currentCalendar]; 

    localNotification.alertBody=@"Good Morning dude..!"; 

    localNotification.alertAction=@"Snooze"; 

    localNotification.repeatInterval=NSDayCalendarUnit; 

    localNotification.soundName=@"goodmorning.caf"; 

[[UIApplication sharedApplication]scheduleLocalNotification:localNotification]; 

我希望這將幫助你......！
