you need to convert dateFormat as per date is coming and after convert it as you want.

Try this below code..

NSString *dateTime = @"Thu Jan 25 10:38:11 2018";
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"EEE MMM dd HH:mm:ss yyyy"];
    NSDate *dateFromString = [dateFormatter dateFromString:dateTime];
    NSLog(@"Date is %@", dateTime);
    // Convert to new Date Format
    [dateFormatter setDateFormat:@"HH:mm:ss"];
    NSString *result = [dateFormatter stringFromDate:dateFromString];
    NSLog(@"result %@",result);

@ishant you can get 10:38:11 in string format in result string – Nirav Kotecha Jan 25 '18 at 05:57
@ishant means you need this same output in `NSDate` format ? – Nirav Kotecha Jan 25 '18 at 08:12

Split the time in date components and use that components as a time.

Check below code.

NSString *aStrTime = @"10:27:43";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"HH:mm:ss"];
NSDate *date = [dateFormatter dateFromString:aStrTime];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components = [calendar components:(NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond) fromDate:date];
NSInteger hour = [components hour];
NSInteger minute = [components minute];
NSInteger sec = [components second];

NSLog(@"%d:%d:%d", hour, minute, sec);

Note: change aStrTime and dateFormatPattern according to your need.

i need to use in local notiifcation. how can i use integer format. – ishant Jan 25 '18 at 05:45
@ishant For local notification, along with the time you have to specify the date (as NSDate) to `fireDate`. – dahiya_boy Jan 25 '18 at 06:04
No but i need on time. on local notification. if i will set with time it will show on selected day only. but i need everyday on same time. – ishant Jan 25 '18 at 06:34
@ishant for that you need to set `repeatInterval`. – dahiya_boy Jan 25 '18 at 06:51

You can try the following code:-

For e.g:- if you are getting the date in 10-02-2017 12:30:50 format

NSString *strDate = @"10-02-2017 12:30:50";
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init]; 
[dateFormat setDateFormat:@"dd-mm-yyyy HH:mm:ss"];
NSDate *date = [dateFormatter dateFromString:strDate];
NSLog(@"The Date is: %@", date);

// By this code you will get the date in NSDate form. Now you can change the format to get the time

[dateFormat setDateFormat:@"HH:mm:ss"];
NSString *strFinalTime = [dateFormatter stringFromDate:strDate];
NSLog(@"strFinalTime: %@",strFinalTime);

i need to convert time to date format
