NSDictionary+JKSafeAccess have a bug

- (NSDate *)jk_dateForKey:(id)key dateFormat:(NSString *)dateFormat{
    NSDateFormatter *formater = [[NSDateFormatter alloc]init];
    formater.dateFormat = dateFormat;
    id value = [self objectForKey:key];
    
    if (value == nil || value == [NSNull null])
    {
        return nil;
    }
    
    if ([value isKindOfClass:[NSString class]] && ![value isEqualToString:@""] && !dateFormat) {
        return [formater dateFromString:value];
    }
    return nil; 
}

!dateFormat
