Error with scrolling custom table cells in a tableview - ios

Question

Hi I'm a newbie to iOS development I'm facing a problem regarding scrolling of custom cells in a tableview. My table view has around 7 cells but once I scroll the view after running I will be getting only first 5 cells like the below but even tough the rest of the cells are being displayed we can't completely scroll to have a look at those cell.
Here's my viewController.m code
#import "ViewController.h"
#import "MobileTableCell.h"
#interface ViewController ()
{
NSArray *tableData;
NSArray *thumbnails;
}
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
tableData = [NSArray arrayWithObjects:#"Iphone 5s",#"Google Nexus 5", #"Samsung Galaxy S4",#"HTC one", #"LG G2", #"Moto X", #"Micromax Turbo", nil];
thumbnails = [NSArray arrayWithObjects:#"iphone5.jpg",#"nexus5.png",#"galaxys4.jpg",#"htcone.jpg",#"lgg2.jpg",#"motox.png",#"micromaxcanvasturbo2.jpg", nil];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [tableData count];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
//#warning Potentially incomplete method implementation.
// Return the number of sections.
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"MyMobileTableCell";
MobileTableCell *cell = (MobileTableCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
//NSLog(#"%#",cell);
if (cell == nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"MobileTableCell" owner:self options:Nil];
cell = [nib objectAtIndex:0];
}
// cell.layer.shouldRasterize = YES;
cell.nameLabel.text = [tableData objectAtIndex:indexPath.row];
cell.thumbnailImageView.image = [UIImage imageNamed:[thumbnails objectAtIndex:indexPath.row]];
return cell;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 78;
}
#end
Please lemme know where I have gone wrong. Thanks in advance.

You are using a UIViewController to render the UITable because you have: #interface ViewController : UIViewController <UItableViewDelegate , UITableViewDataSource>. Better to directly use the UITableViewController provided #interface ViewController : UITableViewController. If you have a valid reason for using a UIView then you need to set the delegate and dataSource to self:
tableView.delegate = self;
tableView.dataSource = self;
You also need to make sure there isn't anything else that is scrollable on the UIView that makes the table view scroll out of the page like a UIScrollView or something like that. You can use auto layout to help keep your stuff in view.
Last point, your issue might be the result of a UINavigationController covering parts of the table. If you are using a UIView you need to add content margin to the UITable to make sure the navigationController does not hide rows.
