UTF 8 string(russian encoding) errors, iphone

English text displays normal, but russian not.How to fix it? I thinked that the problem in UTF8, but I change encoding to UTF8 and no changes.

When you do this:

NSLog(@"%@", list_names);

it calls the -description method for list_names. For an NSArray, this prints the array out as it would appear in an old text plist. The %@ format specifier is normally used for debugging purposes when it's not being used for strings.

The code converts to UTF-8 and then back to an NSString. This round trip operation serves no purpose.

The code uses [NSString stringWithFormat:@"%@", obj]. This is equivalent to calling [obj description].

The code iterates with a variable that is not used in the loop body.

Here is a quick suggestion:

for (NSDictionary *response in [status objectForKey:@"response"]) {
    NSString *firstName = [response objectForKey:@"first_name"];
    NSString *lastName = [response objectForKey:@"last_name"];
    [list_names addObject:[NSString stringWithFormat:@"%@, %@", last_name, first_name]];
}
NSLog(@"%@", list_names);
