cellForRowAtIndexPath is not be called - ios

Question

I have a viewcontroller called BNRItemViewcontroller
In the implementation:
- (instancetype)init{
self = [super initWithStyle:UITableViewStylePlain];
if (self) {
for (int i = 0; i < 5; i++) {
[[BNRItemStore sharedStore]createItem];
}
}
return self;
}
- (instancetype)initWithStyle:(UITableViewStyle)style{
return [self init];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [[[BNRItemStore sharedStore] allItems] count];
}
I add a breakpoint in the cellForRowAtIndexPath: method,but it didn't get in the method.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"UITableViewCell" forIndexPath:indexPath];
NSArray *items = [[BNRItemStore sharedStore] allItems];
BNRItem *item = items[indexPath.row];
cell.textLabel.text = [item description];
return cell;
}

Answer 1

Try this in cellForRowAtIndexPath to fix the crash issue and also check that the delegate properly set or not
static NSString *CellIdentifier = #"yourCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
Thank you

Answer 2

Please make sure you have followed these steps:
Step 1: Conform to UITableViewDataSourceDelegate and UITableViewDelegate
Step 2: Set self.tableView.delegate = self and self.tableView.datasource = self

Answer 3

Please check that you have properly connected "Data Source" and "Delegate" of the tableview to the View Controller either from Code or from storyboard.

Answer 4

Please confirm
add Protocols in your BNRItemViewcontroller just like this : #interface BNRItemViewcontroller() <UITableViewDelegate,UITableViewDataSource>
if you use Storyboard or xib, you should confirm dataSource & delegate with the outlets of Storyboard/xib or write self.tableview.dataSource = self & self.tableview.delegate = self instead.

Answer 5

there are 2 ways
1.Please check that you have properly connected "Data Source" and "Delegate" of tableview
2. self.tableView.delegate = self & self.tableView.datasource = self

Answer 6

Make sure numberOfRowsInSection is not return 0;
- (instancetype)init{
self = [super initWithStyle:UITableViewStylePlain];
if (self) {
self.tableView.dataSource = self;
self.tableView.delegate = self;
for (int i = 0; i < 5; i++) {
[[BNRItemStore sharedStore]createItem];
}
}
return self;
}
EDIT
write this line in init method.
[self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:#"UITableViewCell"];

Answer 7

There can be seven reasons:
Like in accepted answer
Controller needs to conform to UITableViewDataSourceDelegate and UITableViewDelegate
You must assign delegates self.tableView.delegate = self and self.tableView.datasource = self
Futhermore:
numberOfSectionsInTableView must return number > 0 (1 if you want to have one main section)
numberOfRowsInSection must return number > 0
UITableView needs different frame than CGRectZero. You should't create UITableView in that way: self.tableView = [[UITableView alloc] initWithFrame:CGRectZero style:UITableViewStyleGrouped];
heightForRowAtIndexPath must return number > 0
Some other controller (in inheritance) can take delegate methods. Only if you have one tableView for more than one controller.
