It looks like you're adding an NSDate
or an NSURL
object into your dictionary to be converted to JSON. The problem is that JSON doesn't have a "Date" or a "URL" data type. So you need to convert the date / URL into a string (NSString
) and add that instead.

質問
I am trying to convert NSDictionary to JSON object to send it over network. But I am getting an error in converting dictionarty to NSData. Here is my code:
NSError *error=nil;
NSDictionary *loginfbDictionary = [NSDictionary dictionaryWithObjects:objects forKeys:keys];
NSData *d=[NSJSONSerialization dataWithJSONObject:loginfbDictionary options:NSJSONWritingPrettyPrinted error:&error];
NSLog(@"error===>%@",error);
BOOL f=[NSJSONSerialization isValidJSONObject:d];
When I log my dictionary befor converting it into NSData I got it printed. But When I wrote that code after converting dictionary into data I got nothing. I put Debug point after NSData *d... But my code is not executing after that line. I am writing this code in appdelegate file.
Object Contain:
NSArray *keys = [NSArray arrayWithObjects:
@"loginVia",
@"userName",
// @"password",
@"firstName",
@"lastName",
@"gender",
@"dob",
@"email",
@"fb_url",
nil];
NSArray *objects = [NSArray arrayWithObjects:
@"facebook",
[[NSUserDefaults standardUserDefaults] objectForKey:@"username"],
// [[NSUserDefaults standardUserDefaults] objectForKey:@"password"],
[FBUserProfileData objectForKey:@"first_name"],
[FBUserProfileData objectForKey:@"last_name"],
[FBUserProfileData objectForKey:@"gender"],
ds,
[FBUserProfileData objectForKey:@"email"],
fb_url,
nil];
