UILocalNotification在應用程序啓動時被重複調用

我不知道這裏有什麼問題，但是每次運行我的應用程序時，本地通知都會調用重複顯示的fireDate作爲NULL.I正試圖從過去5小時了。我需要幫助！UILocalNotification在應用程序啓動時被重複調用

"<UIConcreteLocalNotification: 0x7f872ead7630>{fire date = (null), time zone = (null), repeat interval = NSCalendarUnitDay, repeat count = UILocalNotificationInfiniteRepeatCount, next fire date = Monday, 7 September 2015 5:32:44 pm India Standard Time, user info = (null)}",

我已經做了足夠的UILocalNotification的研究開始使用它，但我仍然面臨着這個問題。

-(void)setDate:(NSDate*)myfireDate andTime1InString:  (NSString*)time1Str andTime2InString:(NSString*)time2Str andTime3InString:(NSString*)time3Str{ 

    //concatenate myFireDate with all three times one by one 
NSString *myFireDateInString = [dateFormatter stringFromDate:myfireDate]; 
myFireDateInString = [myFireDateInString stringByAppendingString:@" "]; 
NSString *dateWithTime1InString = [myFireDateInString stringByAppendingString:time1Str]; 
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"]; 
NSDate *dateWithTime1 = [dateFormatter dateFromString:dateWithTime1InString]; 

NSString *mySecondFireDateInString; 
NSString *dateWithTime2InString; 
NSDate *dateWithTime2; 
if ([time2Str length] !=0){ 
    [dateFormatter setDateFormat:@"yyyy-MM-dd"]; 
    mySecondFireDateInString = [dateFormatter stringFromDate:myfireDate]; 
    mySecondFireDateInString = [mySecondFireDateInString stringByAppendingString:@" "]; 
    dateWithTime2InString = [mySecondFireDateInString stringByAppendingString:time2Str]; 
    [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"]; 
    dateWithTime2 = [dateFormatter dateFromString:dateWithTime2InString]; 
} 

NSString *myThirdFireDateInString; 
NSString *dateWithTime3InString; 
NSDate *dateWithTime3; 
if ([time3Str length]!=0){ 
    [dateFormatter setDateFormat:@"yyyy-MM-dd"]; 
    myThirdFireDateInString = [dateFormatter stringFromDate:myfireDate]; 
    myThirdFireDateInString = [myThirdFireDateInString stringByAppendingString:@" "]; 
    dateWithTime3InString = [myThirdFireDateInString stringByAppendingString:time3Str]; 
    [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"]; 
    dateWithTime3 = [dateFormatter dateFromString:dateWithTime3InString]; 
} 

NSLog(@"%@",dateWithTime3); 
NSLog(@"%@",dateWithTime2); 
    //block starts here 
    void(^notificationBlock)(void) = ^{

，你必須設置通知 – baydi

錯誤可能發生在這裏的代碼粘貼重複計數爲UILocalNotificationInfiniteRepeatCount檢查一次你的UILocalNotification –

的計數這裏是我的代碼.. ... – Reckoner

這是發生怎麼一回事，因爲您要設置

appDelegate.localNotification.repeatInterval = someUnit;

嘗試通過檢查repeatCount是否爲0或不按repeatInterval值設置爲1。

您只能設置repeatInterval屬性的預定義枚舉。 – Reckoner

是的，我讀了這個。設置0作爲一個值可以防止無限重複計數，但它不起作用。 – Reckoner

我得到了解決方案。在該方法中，didReceiveLocalNotification：，我將通知對象添加到'scheduledNotifications'數組。每次安排通知時，同一個對象被添加到'scheduledNotifications'數組中那一次又一次地被解僱了。

[UIApplication sharedApplication]scheduledNotifications = notification;

注：忽略didReceiveLocalNotification這一說法：
