How to parse nsmutabledictionary time in iOS?

Question

I have parsed the Json using following code

- (void) getWorkingCalendar:(NSData *)dataForParse{

    NSMutableArray *locations = [[NSMutableArray alloc] init];

    NSString* myString;
    myString = [[NSString alloc] initWithData:dataForParse encoding:NSASCIIStringEncoding];

    NSLog(@"data is %@", myString);

    NSArray * parsedData = [NSJSONSerialization JSONObjectWithData:dataForParse options:kNilOptions error:nil];

    NSLog(@"parser data %@", parsedData);


    for (NSDictionary *dict in parsedData) {


        NSLog(@"Value is %@", dict);

    }

    [delegate array:locations];


}

Output as below

2014-04-30 12:44:41.828 Testing[827:60b] parser data (
    "/Date(1399016682788+0400)/",

How can I get time slot in NSString from NSDictionary?

Thanks in Advance.

wow... what kind of date is "`14014353123412341234431+0800`"? — Michael Dautermann, Apr 30 '14 at 07:57

your service is returning wrong format of date.. Service side is sending directly date object without converting that into date string.. — Salman Zaidi, Apr 30 '14 at 08:01
these are mili seconds, but i dont' know how to code them in IOS? — Chatar Veer Suthar, Apr 30 '14 at 08:01
I think I need to convert this miliseconds value into date, but I dont' know how to do so :( — Chatar Veer Suthar, Apr 30 '14 at 08:02
(long long)([[NSDate date] timeIntervalSince1970] * 1000.0)???? I saw on that website, but query is , how to fetch value from such NSDictionary? — Chatar Veer Suthar, Apr 30 '14 at 08:10

You might need to tweak this a bit, but this is what I've used with these kind of dates:

Header File

@interface NSDate (JSON)

+ (NSDate *)dateFromJSON:(NSString *)dateString;

@end

Implementation

#import "NSDate+JSON.h"

@implementation NSDate (JSON)

+ (NSDate *)dateFromJSON:(NSString *)dateString {

    if (dateString == nil || [dateString isKindOfClass:[NSNull class]]) {
        return nil;
    }

    NSString *header = @"/Date(";
    NSRange headerRange = [dateString rangeOfString:header];
    if (headerRange.location != 0) {
        return nil;
    }

    NSString *footer = @")/";
    NSRange footerRange = [dateString rangeOfString:footer options:NSBackwardsSearch];
    if (footerRange.location == NSNotFound || footerRange.location + footerRange.length != dateString.length) {
        return nil;
    }

    NSString *timestampString = [dateString substringWithRange:NSMakeRange(headerRange.length, footerRange.location - headerRange.length)];

    NSTimeInterval interval = [timestampString doubleValue] * 0.001;
    return [NSDate dateWithTimeIntervalSince1970:interval];
}

@end

This example does not include the time zone that is in your date, so you might want to add that.

Then use it like:

for (NSString *dateValue in parsedData) {
     NSDate *date = [NSDate dateFromJSON:dateValue];
}
