我正在发送一个帖子请求但是当我从jsonDict中提取值时，我得到一个额外的括号，因此设置为我的标签的值没有被设置，因为这个额外的括号“（”
下面是我的帖子方法
NSString *post = [NSString stringWithFormat:@"store_id=%@",self.str];
NSLog(@"DATA sending details :%@",self.str);
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
//Next up, we read the postData's length, so we can pass it along in the request.
NSString *postLength = [NSString stringWithFormat:@"%lu", (unsigned long)[postData length]];
// Now that we have what we'd like to post, we can create an NSMutableURLRequest, and include our postData
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:@"http://riterp.com/all_product.php"]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody:postData];
NSLog(@"the data Details is %@", post);
// And finally, we can send our request, and read the reply by creating a new NSURLSession:
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession* sharedSessionMainQueue = [NSURLSession sessionWithConfiguration:configuration delegate:nil delegateQueue:[NSOperationQueue mainQueue]];
NSLog(@"Request = %@", request);
[[sharedSessionMainQueue dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSString *requestReply = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding]; // this is json st
NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error]; // you need to convert to dictionary object
//NSDictionary *temp=jsonDict;
NSLog(@"Req cust 3:%@",requestReply);
NSLog(@"requestReply cust liqour categoryn= 3: %@", jsonDict);
NSLog(@"liq new val %@",[[[jsonDict valueForKey:@"items"] objectAtIndex:0]mutableCopy]);
_itemss=[[[jsonDict valueForKey:@"items"]objectAtIndex:0]mutableCopy];
NSLog(@"------------------%@",_itemss);
_nametb=[_itemss valueForKey:@"liquor_name"];
NSLog(@"name tb -------%@",_nametb);
_regtb=[_itemss valueForKey:@"base_price_old"];
NSLog(@"regular tb -------%@",_regtb);
_buytb=[_itemss valueForKey:@"bidacceptance_price"];
NSLog(@"buy tb -------%@",_buytb);
_lowesttb=[_itemss valueForKey:@"min_price"];
NSLog(@"lowest tb -------%@",_lowesttb);
}] resume];
以及我从服务器获取的数据
