Fill a tableview with content of array NOT working - ios

Question

Basically what i want to do is i want to fill a table view with strings from an array. I've made a second UIviewcontroller and a custom cell with that show an image and two other labels. But when i run the code, there is no error messages but the tableview is blank, almost like its not recognizing the code at all. I have declared a delegate and datasource for it in the .h file.
#import "ViewController4.h"
#import "Cell.h"
#import "XMLparse.h"
#interface ViewController4 ()
#end
#implementation ViewController4
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
-(NSMutableArray *)objects {
if (!Datarray) {
Datarray = [[NSMutableArray alloc]init];
}
return Datarray;
}
- (void)viewDidLoad
{
[super viewDidLoad];
Datarray = [[NSMutableArray alloc]initWithObjects:#"USD",#"EUR",#"JPY",#"BGN",#"CZK",#"DKK",#"GBP",#"HUF",#"LTL",#"PLN",#"RON",#"SEK",#"CHF",#"NOK",#"HRK",#"RUB",#"TRY",#"AUD",#"BRL",#"CAD",#"CNY",#"HKD",#"IDR",#"ILS",#"INR",#"KRW",#"MXN",#"MYR",#"NZD",#"PHP",#"SGD",#"THB",#"ZAR", nil];
Tableview.delegate = self;
XMLparse *datee = [[XMLparse alloc]init];
[datee loadDataFromXML];
Date.text = [NSString stringWithFormat:#"Last updated: %#",[datee tid]];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (NSInteger)numberOfSectionsInTableview:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableview numberOfRowsInSection:(NSInteger)section {
return [Datarray count];
}
- (CGFloat)tableView:(UITableView *)tableview heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 78;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"Cell";
Cell *cell = (Cell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"Cell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
// cell.ratename.text = [tableData objectAtIndex:indexPath.row];
// cell.thumbnailImageView.image = [UIImage imageNamed:[thumbnails objectAtIndex:indexPath.row]];
cell.currencyname.text = [Datarray objectAtIndex:indexPath.row];
return cell;
}

You have to set self to datasource property of UITableView. I suggest you the following code edited.
- (void)viewDidLoad
{
[super viewDidLoad];
Datarray = [[NSMutableArray alloc]initWithObjects:#"USD",#"EUR",#"JPY",#"BGN",#"CZK",#"DKK",#"GBP",#"HUF",#"LTL",#"PLN",#"RON",#"SEK",#"CHF",#"NOK",#"HRK",#"RUB",#"TRY",#"AUD",#"BRL",#"CAD",#"CNY",#"HKD",#"IDR",#"ILS",#"INR",#"KRW",#"MXN",#"MYR",#"NZD",#"PHP",#"SGD",#"THB",#"ZAR", nil];
Tableview.delegate = self;
Tableview.dataSource = self; // <---- added code for setting datasource.
XMLparse *datee = [[XMLparse alloc]init];
[datee loadDataFromXML];
Date.text = [NSString stringWithFormat:#"Last updated: %#",[datee tid]];
}
