Pushed view controller does not cover entire screen - ios

Question

I have created a application which displays the contacts in my device in a table view and when i click a row it will display the details of that contact on another view. This is how the storyboard looks like:
In my didSelectRowAtIndexPath i have this code:
NewViewController *WVC = [self.storyboard instantiateViewControllerWithIdentifier:#"NewViewController"];
[self.navigationController pushViewController:WVC animated:YES];
When i run the application, the app looks like:
However when i click on a row the details are displayed, but like this:
Can someone let me know where i am going wrong, thanks in advance.
Code in NewViewController.m
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.view.backgroundColor = [UIColor whiteColor];
nameLabel = [[UILabel alloc]initWithFrame:CGRectMake(10, 100, 300, 20)];
mylabel = [[UILabel alloc]initWithFrame:CGRectMake(10, 125, 300 , 20)];
[nameLabel setText:#"Name :"];
[mylabel setText:_LabelText];
[self.view addSubview:nameLabel];
[self.view addSubview:mylabel];
myPhonelabel = [[UILabel alloc]initWithFrame:CGRectMake(10, 175, 300, 20)];
[myPhonelabel setText:#"Contact Number :"];
PhoneLabel = [[UILabel alloc]initWithFrame:CGRectMake(10, 200, 300, 20)];
[PhoneLabel setText:_phoneNumber];
[self.view addSubview:myPhonelabel];
[self.view addSubview:PhoneLabel];
myEmailLabel = [[UILabel alloc]initWithFrame:CGRectMake(10, 240, 300, 20)];
[myEmailLabel setText:#"Email ID :"];
EmailLabel = [[UILabel alloc]initWithFrame:CGRectMake(10, 265, 300, 20)];
[EmailLabel setText:_emailId];
[self.view addSubview:myEmailLabel];
[self.view addSubview:EmailLabel];
myBdayLabel =[[UILabel alloc]initWithFrame:CGRectMake(10, 315, 300, 20)];
[myBdayLabel setText:#"Date Of Birth :"];
BdayLabel = [[UILabel alloc]initWithFrame:CGRectMake(10, 335, 300, 20)];
[BdayLabel setText:_birthDate];
[self.view addSubview:myBdayLabel];
[self.view addSubview:BdayLabel];
myButton = [[UIButton alloc]initWithFrame:CGRectMake(10, 30, 300, 30)];
[myButton setTitle:#"Contact Details" forState:UIControlStateNormal];
[myButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
myButton.backgroundColor = [UIColor colorWithRed:0xBD/255.0 green:0xBE/255.0 blue:0xC2/255.0 alpha:1];
myButton.layer.cornerRadius = 10;
myButton.clipsToBounds = YES;
[self.view addSubview:myButton];
}
EDIT: (ANSWER)
After a lot of head banging and hair pulling, the problem was solved by replacing
NewViewController *WVC = [self.storyboard instantiateViewControllerWithIdentifier:#"NewViewController"];
with
NewViewController *WVC = [[NewViewController alloc] init];
Honestly i don't know why the previous one didn't work.

If you don't need navigation bar, use to hide it
[self.navigationController setNavigationBarHidden:YES];
