UITableView datasource methods not called on reloadData in IOS - ios

Question

I am stucked in this problem for many hours and have n't found any solution on SO...
I have got a table as a subview in UIViewController. When view loads, all datasource methods are called for tableview, but as I receive data from server and call [someTable reloadData], none of the data source methods are called. I have confirmed through breakpoints that my array do contains 100 objects. Also both delegate and datasource are bind to File owner in IB.
What can be possibly missing ? Please help me... Thanks :(
OutLogController.h
#interface OutLogController : UIViewController<UITableViewDataSource,UITableViewDelegate,ASIHTTPRequestDelegate>
{
NSMutableArray *outstandingKeys;
}
#property (strong, nonatomic) IBOutlet UITableView *someTable;
#end
OutLogController.m
#interface OutLogController ()
#end
#implementation OutLogController
#synthesize someTable;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
outstandingKeys = [[NSMutableArray alloc] init];
someTable = [[UITableView alloc] initWithFrame:self.view.frame style:UITableViewStylePlain];
someTable.rowHeight = 85;
[self retrieveOutstandingLogFromServer];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return outstandingKeys.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// Configure the cell...
LogUnit *unit = [outstandingKeys objectAtIndex:indexPath.row];
cell.textLabel.text = unit.symbol;
return cell;
}
-(CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 85;
}
-(void) requestFinished:(ASIHTTPRequest *)request
{
NSLog(#"%#",request.responseString);
NSArray *list = [request.responseString JSONValue];//contains 100 objects
for (int i = 0; i < list.count; i++) {
NSArray *singleTrade = [[list objectAtIndex:i] JSONValue];
LogUnit *unit = [[LogUnit alloc] init];
unit.symbol = [singleTrade objectAtIndex:0];
unit.type = [singleTrade objectAtIndex:1];
unit.price = [singleTrade objectAtIndex:2];
unit.remaining = [singleTrade objectAtIndex:3];
unit.order = [singleTrade objectAtIndex:4];
unit.time = [singleTrade objectAtIndex:5];
[outstandingKeys addObject:unit];
}
if(outstandingKeys.count > 0)
{
[someTable reloadData];//does reload table
}
}
EDIT
After removing line:
someTable = [[UITableView alloc] initWithFrame:self.view.frame style:UITableViewStylePlain];
Datasource methods are called except cellForRowAtIndexPath and table disappears from view since this method is not called. Any idea why it can't get called?
Note: I have confirmed that I have count = 100 after response from server.

Answer 1

someTable = [[UITableView alloc] initWithFrame:self.view.frame style:UITableViewStylePlain];
You have already bind your UITableView from nib/storyboard. In this case you did not have to alloc again the tableview. Removing this line will do the work

Answer 2

someTable = [[UITableView alloc] initWithFrame:self.view.frame style:UITableViewStylePlain];
You create new tableView and it doesn't add to current view.

Answer 3

check your outstandingKeys Count may it zero count

Answer 4

Try to reload data by performing it on main thread..
dispatch_async(dispatch_get_main_queue(), ^{
[self.tableRating reloadData];
});
This will solve your problem. Happy Coding..
