JSON from PHP to Objective C

Question

I have problem with UTF-8 symbols. I send data from PHP server to my app.

PHP code:

$json = json_encode ($array, JSON_UNESCAPED_UNICODE); echo $json;

Objective C code:

- (void)connectionDidFinishLoading:(NSURLConnection *)connection { NSString *response = [[NSString alloc] initWithData:_mutableData encoding:NSUTF8StringEncoding]; NSLog(@"%@", response); NSError * error=nil; NSDictionary * parsedData = [NSJSONSerialization JSONObjectWithData:_mutableData options:kNilOptions error:&error]; NSLog(@"%@", parsedData); }

Objective C code will output:

{"name":"1sФ 女"}

And for second NSLog:

{ name = "1s\U0424 \U5973"; }

If I remove JSON_UNESCAPED_UNICODE option from PHP code I get this output:

{"name":"1s\u0424 \u5973"}

And for second NSLog:

{ name = "1s\U0424 \U5973"; }

So, nothing really changed for me. How to get properly encoded string ("1sФ 女") in NSDictionary?

Take a look at this article.

NSLog uses the description method for printing NSDictionary, and that prints all non-ASCII characters in the escaped form. NSLog is used mainly for debug so this should not be a problem as the NSDictionary contains the wanted unicode characters.

You are totally right. String is properly encoded when you output NSString object or put it in UILabel. Thanks.
