Objective - C - UITableView cellForRowAtIndexPath never called - ios

Question

I know that this question have been asked so many times but unfortunately non of the solutions in those questions worked for me.
Here are some of the things I tried:
making sure that numberOfSectionsInTableView is not returning 0
making sure that numberOfRowsInSection is not returning 0.
insuring that reloadData is being called on the main thread by using performSelectorOnMainThread as shown below:
[self.tableView performSelectorOnMainThread:#selector(reloadData) withObject:nil waitUntilDone:NO]
setting the delegate :
self.tableView.dataSource = self; self.tableView.delegate = self;
making sure that tableview background color was changed.
making sure that tableview frame was adjustable.
But cellForRowAtIndexPath method never called
Please find the code:
UITableView *tableView;
- (void)viewDidLoad {
[super viewDidLoad];
self.tableView = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, 320,480) style:UITableViewStylePlain];
self.tableView.delegate = self;
self.tableView.dataSource = self;
[self.view addSubview:self.tableView]
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 3;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
cell.textLabel.text = "test";
return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
return 44;
}
If you have any idea what to do, please let me know.
Thanks

Answer 1

You created the tableView added it as subView to your ViewController's view in ViewDidLoad() which is fine :) But where are you calling reload Data on tableView buddy :)
Add
- (void)viewDidLoad {
[super viewDidLoad];
self.tableView = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, 320,480) style:UITableViewStylePlain];
self.tableView.delegate = self;
self.tableView.dataSource = self;
[self.view addSubview:self.tableView]
[self.tableView reloadData];
}
It will work like a charm :)

Answer 2

just uninstall app from simulator and run again. sometimes its not work.

Answer 3

you have to delegate and datasource Protocol to view controller
#interface ViewController ()<UITableViewDelegate,UITableViewDataSource>

Answer 4

First
#interface yourController ()<UITableViewDelegate,UITableViewDataSource>
Second
-(void)viewDidLoad {
[super viewDidLoad];
self.tableView = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, 320,480) style:UITableViewStylePlain];
[self reloadData]; //call your webservice here
self.tableView.delegate = self;
self.tableView.dataSource = self;
[self.view addSubview:self.tableView]
[self.tableView reloadData]; //most imp
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return yourArray.count; //your array which is get from webservice
}
