JSON Data in UITableViewCell - ios

Question

Hi I am developing one quizz app and the issue is, I have the following JSON Data, which is a respond from my WebService.
[
{
"id": "3",
"question": "tes!2t",
"option1": "test",
"option2": "test",
"option3": "test",
"option4": "test",
"correct_answer": "test",
"explanation": "test",
"image": "test",
"created_at": "2014-09-23 02:00:00",
"updated_at": "2014-09-09 06:19:28"
}
]
How can I display the Data option1,option2,option3 and option4 in a TableViewCell.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 4;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:#"MyCell"];
if (cell==nil)
{
cell=[[UITableViewCell alloc]initWithFrame:CGRectZero];
}
NSString *urlString = #"http://localhost/quiz/public/questions";
NSData *JSONData = [NSData dataWithContentsOfFile:urlString:NSDataReadingMappedIfSafe error:nil];
NSDictionary *jsonObject = [NSJSONSerialization JSONObjectWithData:JSONData options:NSJSONReadingMutableContainers error:nil];
NSArray *array = [jsonObject objectForKey:#"questions"];
questions = [[NSMutableArray alloc] initWithCapacity:[array count]];
//choices = [[NSArray alloc] init];
for (NSDictionary *dict in array) {
question = [[Questions alloc] initWithObject:dict];
[questions addObject:question];
}
cell.textLabel.text = [choices objectAtIndex:indexPath.row];
cell.textLabel.font=[UIFont fontWithName:#"Bold" size:12];
cell.backgroundColor=[UIColor grayColor];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
int selectedRow = indexPath.row;
NSString *filePathChoices = [[NSBundle mainBundle] pathForResource:#"questions" ofType:#"json"];
NSData *JSONDataChoices = [NSData dataWithContentsOfFile:urlString
:NSDataReadingMappedIfSafe error:nil];
NSMutableDictionary *jsonObjectChoices = [NSJSONSerialization JSONObjectWithData:JSONDataChoices options:NSJSONReadingMutableContainers error:nil];
Any help would be appreciated. Thanks in advance !

Answer 1

Try this hopefully it will works:
NSString *urlString = #"your URL";
NSURL *url = [NSURL URLWithString:urlString];
NSData *data = [NSData dataWithContentsOfURL:url];
NSError *error;
jsonObject = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error];
jsonDict11 = [jsonObject valueForKey:#"question"];
NSLog(#"array %#",jsonDict11);
NSLog(#"Count : %d", [jsonDict11 count]);
Questionscount=[jsonDict11 count];
self.QuestionsText.text=[jsonDict11 objectAtIndex:ii];
In TableView:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:#"MyCell"];
if (cell==nil)
{
cell=[[UITableViewCell alloc]initWithFrame:CGRectZero];
}
NSArray *jsonDict1=[jsonObject valueForKey:#"option1"];
NSArray *jsonDict2=[jsonObject valueForKey:#"option2"];
NSArray *jsonDict3=[jsonObject valueForKey:#"option3"];
NSArray *jsonDict4=[jsonObject valueForKey:#"option4"];
NSString *str1=[jsonDict1 objectAtIndex:ii];
NSString *str2=[jsonDict2 objectAtIndex:ii];
NSString *str3=[jsonDict3 objectAtIndex:ii];
NSString *str4=[jsonDict4 objectAtIndex:ii];
nameArr = [NSArray arrayWithObjects:str1,str2,str3,str4,nil];
cell.textLabel.text = [nameArr objectAtIndex:indexPath.row];
return cell;
}

Try this:
NSString *jsonString = #"[{\"id\":\"3\",\"question\":\"tes!2t\",\"option1\":\"test\",\"option2\":\"test\",\"option3\":\"test\",\"option4\":\"test\",\"correct_answer\":\"test\",\"explanation\":\"test\",\"image\":\"test\",\"created_at\":\"2014-09-23 02:00:00\",\"updated_at\":\"2014-09-09 06:19:28\"}]";
Pass your json string ("jsonString")
NSData *aDataJson = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSError *aError = nil;
NSArray *aArrJson = [NSJSONSerialization JSONObjectWithData:aDataJson options:NSJSONReadingMutableContainers error: &aError];
NSLog(#"%#",aArrJson);
NSLog(#"%#",[[aArrJson objectAtIndex:0] objectForKey:#"question"]);
