NSInvalidArgumentException, reason: 'Invalid type in JSON write (__NSDate)'

Question

I\'m getting this exception when I try to JSON encode NSDate object.I believe NSDate is not compatible for JSON encoding. but I must encode the date.Any solutions?

Answer 1

Convert NSDate to NSString and try to encode.

- (NSString *) changeDateToDateString :(NSDate *) date {

    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setTimeZone:[NSTimeZone localTimeZone]];
    NSLocale *locale = [NSLocale currentLocale];
    NSString *dateFormat = [NSDateFormatter dateFormatFromTemplate:@"hh mm" options:0 locale:locale];
    [dateFormatter setDateFormat:dateFormat];
    [dateFormatter setLocale:locale];
    NSString *dateString = [dateFormatter stringFromDate:date];
    return dateString;
}
