So this is my Code:
TableViewController.h
#interface TableViewController : UITableViewController
#property (nonatomic, strong) NSArray *blogPosts;
#end
TableViewController.m
- (void)viewDidLoad
{
[super viewDidLoad];
NSURL *blogURL = [NSURL URLWithString:#"http://blog.teamtreehouse.com/api/get_recent_summary/"];
NSData *jsonData = [NSData dataWithContentsOfURL:blogURL];
NSError *error = nil;
NSDictionary *dataDictionary = [NSJSONSerialization JSONObjectWithData:jsonData
options:0 error:&error];
self.blogPosts = [dataDictionary objectForKey:#"posts"];
}
With this being displayed on the log
2014-04-15 20:21:48.884 BlogReader[772:60b] Cannot find executable for CFBundle 0xa181ef0 (not loaded)
I forgot to make sure that the Author and Title strings matched the same ones as the ones in the JSON
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
NSDictionary *blogPost = [self.blogPosts objectAtIndex:indexPath.row];
// Extracting 'Title' and 'Author' from dictionary to display in cell
cell.textLabel.text = [blogPost valueForKey:#"title"];
cell.detailTextLabel.text = [blogPost valueForKey:#"author"];
return cell;
}

I have viewController with tableView, tableView has two prototype cells, second cell has sno, date, amount 3 labels. I created TableViewCell class and i created 3 outlets for this 3 labels in this TableViewCell class. I am getting data from server and i want to assign that data to this 3 labels. How?
In tableViewCell.h
#property (weak, nonatomic) IBOutlet UILabel *serialNumber;
#property (weak, nonatomic) IBOutlet UILabel *dateLabel;
#property (weak, nonatomic) IBOutlet UILabel *amountLabel;

or change sequence

Use this code

Good afternoon,
I'm trying to use a NSMutableArray in my TableViewController from a JSON output and I'm a little bit lost because currently I can store my JSON data in a NSMutableArray, and I have checked with a NSLog that the content is OK, but now I have to show that data in my TableViewController and that's when I'm lost.
I'm using an another example of TableViewController using NSArray but now I have to modify it for a NSMutableArray. If you can help me with some code or show me some examples or tutorials I will be much appreciated.
I know in my code maybe I have something wrong because I'm using an old example using only NSArray but I'm showing you because that's what I don't know how to do, I need to work with NSMutableArray and that's why I'm asking for your help.
How can I show a NSMutableArray in my TableViewController?

Declare NSMutableArray *jsonArray ; as global
-(void)fetchJson {
dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
dispatch_async(queue, ^{
NSString * urlString = [NSString stringWithFormat:#"http://website.com/service.php"];
NSURL * url = [NSURL URLWithString:urlString];
NSData * data = [NSData dataWithContentsOfURL:url];
//NSError * error;
//NSMutableArray *json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
// I advice that you make your carModels mutable array and initialise it here,before start working with json
//self.carModels = [[NSMutableArray alloc] init];
#try
{
NSError *error;
[jsonArray removeAllObjects];
jsonArray = [NSJSONSerialization
JSONObjectWithData:data
options:NSJSONReadingMutableContainers|NSJSONReadingMutableLeaves
error:&error];
}
#catch (NSException * e)
{
NSLog(#"Exception: %#", e);
}
#finally
{
[self.tableView reloadData]
}
}
);
}
To Display The TableView Like This
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return [jsonArray count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"carTableCell";
CarTableViewCell *cell = [tableView
dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[CarTableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];
}
// Configure the cell...
cell.makeLabel.text = [[jsonArray objectAtIndex:indexPath.row] valueForKey:#"imagen"];
cell.modelLabel.text = [[jsonArray objectAtIndex:indexPath.row] valueForKey:#"user"];
UIImage *carPhoto = [[jsonArray objectAtIndex:indexPath.row] valueForKey:#"date"];
cell.carImage.image = carPhoto;
return cell;
}
Add
[self.tableView reloadData]
after you have fetched and parsed the JSON.
Whenever you change table datas from different array just add [self.tableView reloadData] in you method.
It will remove old data & shows new data into your tableview.
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 {

[questions addObject:question];
}

cell.textLabel.font=[UIFont fontWithName:#"Bold" size:12];
cell.backgroundColor=[UIColor grayColor];
return cell;
}

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 !
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"]);
Loading gifs into my UITableViewCell using SDWebImage. It's actually really fast, but the tableview doesn't seem to load up until the user actually scrolls the tableview.
Any suggestions for how to fix this issue?
This is my UITableView
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return self.gifArray.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *MyIdentifier = #"Cell";
RDGifGridTableViewCell *cell = (RDGifGridTableViewCell *)[tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"RDGifGridTableViewCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
cell.urlLabel.text = [self.gifArray objectAtIndex:indexPath.row];
cell.urlLabel.textColor = [UIColor clearColor];
[cell.imageView sd_setImageWithURL:[NSURL URLWithString:cell.urlLabel.text] placeholderImage:nil options:SDWebImageCacheMemoryOnly];
return cell;
}
This is how I add content to the array which occurs in viewDidLoad:
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlString]];
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
[NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
NSArray *idArray = [json objectForKey:#"data"];
for (NSDictionary *ids in idArray) {
NSDictionary *images = ids[#"images"];
NSDictionary *fixedHeightImage = images[#"fixed_width"];
self.gifURL = fixedHeightImage[#"url"];
[self.gifArray addObject:self.gifURL];
[self.tableView reloadData];
}
The following line might be the problem
static NSString *MyIdentifier = #"Cell";
When your cells are being reused you are using a different cellIdentfier RDGifGridTableViewCell.
It should be the same cell being reused.
So just fix this line and use that variable again when it's nil to avoid such mistake, oh and while you're at it, consider renaming your variable to first letter lowercase myIdentifier as Objective C naming convention suggests.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *MyIdentifier = #"RDGifGridTableViewCell";
RDGifGridTableViewCell *cell = (RDGifGridTableViewCell *)[tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"RDGifGridTableViewCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
cell.urlLabel.text = [self.gifArray objectAtIndex:indexPath.row];
cell.urlLabel.textColor = [UIColor clearColor];
[cell.imageView sd_setImageWithURL:[NSURL URLWithString:cell.urlLabel.text] placeholderImage:nil options:SDWebImageCacheMemoryOnly];
return cell;
}
