iOS how to display dictionary keys into table cells - ios

Question

I have a dictionary declared as "res". This "res" contains response of JSON data.
I did a valueforkey = "id" to retrieve out the list of id.
When I want to display each id into the tableview it turns out it only displays the same id repetively.
Here is my tableview:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [res count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableViews dequeueReusableCellWithIdentifier:#"cell"];
cell.textLabel.lineBreakMode = NSLineBreakByWordWrapping;
cell.textLabel.numberOfLines = 0;
cell.textLabel.textColor =[UIColor blackColor];
cell.textLabel.font = [UIFont systemFontOfSize:17.0];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
for(int i = 0; i<res.count; i++)
cell.textLabel.text = [NSString stringWithFormat:#"ID: %#",[res valueForKey:#"id"]];
return cell;
}
- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{
UIView *view = [[UIView alloc] init];
return view;
}
When i NSLOG out the res with value "id" :
icon = [res valueForKey:#"id"];
NSLog(#"icon: %#", icon);
it shows:
icon: (
300122,
300228,
300235,
300272,
300265,
300242,
300198,
300135,
300282,
300255,
300245,
300248,
300185,
300118,
300275,
300295,
300005,
300062,

300055,

300018,

300038,
300105,
300002,
300072,
300022,
300025,
300028,
300035,
300258,
300088,
300262,
300128,
300215,
300142,
300078,

300238,
300302,
300232,
300285,
300132,
300102
)
Question is how do i display each id on each cell in the tableview?

Answer 1

Set an array of allKeys
NSArray *array = [NSArray arrayWithArray:[yourDictionary allKeys]];'
then just set your tableView dataSource using this array.
e.g
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableViews dequeueReusableCellWithIdentifier:#"cell"];
cell.textLabel.lineBreakMode = NSLineBreakByWordWrapping;
cell.textLabel.numberOfLines = 0;
cell.textLabel.textColor =[UIColor blackColor];
cell.textLabel.font = [UIFont systemFontOfSize:17.0];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
cell.textLabel.text = [NSString stringWithFormat:#"ID: %#",[array objectAtIndex:indexPath.row]];
return cell;
}

Answer 2

Replace numberOfRowsInSection with:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
NSArray *arrIds = (NSArray *)[res valueForKey:#"id"];
return arrIds.count;
}
And replace
for(int i = 0; i<res.count; i++)
cell.textLabel.text = [NSString stringWithFormat:#"ID: %#",[res valueForKey:#"id"]];
with
NSArray *arrIds = (NSArray *)[res valueForKey:#"id"];
cell.textLabel.text = [NSString stringWithFormat:#"ID: %#",[arrIds objectAtIndex:indexPath.row]];

Answer 3

Store your #"id" values in one array as follows;
NSArray *icon = [res valueForKey:#"id"];
NSLog(#"icon: %#", icon);
Then use that array to display values in TableView cell as follows;
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableViews dequeueReusableCellWithIdentifier:#"cell"];
cell.textLabel.text = [NSString stringWithFormat:#"ID: %#",[icon objectAtIndex:indexPath.row]];
return cell;
}

Answer 4

Replace line below
for(int i = 0; i<res.count; i++)
cell.textLabel.text = [NSString stringWithFormat:#"ID: %#",[res valueForKey:#"id"]];
with line
cell.textLabel.text = [NSString stringWithFormat:#"ID: %#",[[res valueForKey:#"id"] objectAtIndex:indexPath.row]];
your for loop logic is not correct to achieve the goal. We have tableView's default indexPath object to fetch current row in tableview, so fetch the value from your at the tableview's indexPath from your array.

Answer 5

in
ViewDidload{
NSArray * iconArray = [res allKeys];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableViews dequeueReusableCellWithIdentifier:#"cell"];
cell.textLabel.lineBreakMode = NSLineBreakByWordWrapping;
cell.textLabel.numberOfLines = 0;
cell.textLabel.textColor =[UIColor blackColor];
cell.textLabel.font = [UIFont systemFontOfSize:17.0];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
cell.textLabel.text = [NSString stringWithFormat:#"ID: %#",[iconArray objectAtIndex:indexPath.row]];
return cell;
}
