You should be able to use to use NSDateFormatter to format the style of time you want, then read in the string to the formatter and pull it back out in your desired format.

// Get your 24 hr time String format
NSString *timeString = [NSString stringWithFormat:@"%@",[[[arr valueForKey:@"data"] valueForKey:@"pickup_time"] objectAtIndex:indexPath.row]]; 

//Store your 24 hr time String format into string
        NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
        [dateFormatter setDateFormat:@"HH:mm:ss"];
        NSDate *time = [dateFormatter dateFromString:timeString];

// Convert time object into desired format
[dateFormatter setDateFormat:@"hh:mm.a"];
cell.lbl_BookingTm.text = [NSString stringWithFormat:@"%@",[dateFormatter stringFromDate:time]];    //Get your string into 12 hr time String format

Use NSDateFormatter to turn the string in a NSDate. Then use the dateformatter again to change the NSDate to a string.

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
dateFormatter.dateFormat = @"HH:mm";
NSDate *date = [dateFormatter dateFromString:@"15:15"];

dateFormatter.dateFormat = @"hh:mm a";
NSString *pmamDateString = [dateFormatter stringFromDate:date];

Code might contain some errors, written without compiling or testing.
