Json字符串从IOS发送到PHP服务器？

Question

当我尝试将 JSON 字符串发送到服务器时，结果似乎是这样的

  

＆＃34; [＆＃34; sudheer@gmail.com"，＆＃34; venkat@gmail.com"]＆＃34;

如何删除开始和结束双引号响应。

我在做什么错，为什么会这样？

我想输出

  

[＆＃34; sudheer@gmail.com"，＆＃34; venkat@gmail.com"]

AppDelegate *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];


NSString *url = [NSString stringWithFormat:@"http://myurl........."];
NSArray *arrayOfStrings = @[@"sudheer@gmail.com", @"venkat@gmail.com"];
NSError *error = nil;
NSData *json;
NSString *jsonString;

if ([NSJSONSerialization isValidJSONObject:arrayOfStrings])
{
    // Serialize the dictionary
    json = [NSJSONSerialization dataWithJSONObject:arrayOfStrings options:NSJSONWritingPrettyPrinted error:&error];

    // If no errors, let's view the JSON
    if (json != nil && error == nil)
    {
        jsonString = [[NSString alloc] initWithData:json encoding:NSUTF8StringEncoding];

        NSLog(@"JSON: %@", jsonString);

        //NSString *cleanedString=[jsonString stringByReplacingOccurrencesOfString:@"/"" withString:@""];

    }
}

//NSString *emails = [addSponsorEmailStringInModel componentsJoinedByString:@","];
