推动的视图控制器不会覆盖整个屏幕

Question

我创建了一个应用程序，它在表格视图中显示设备中的联系人，当我单击一行时，它将在另一个视图上显示该联系人的详细信息。这就是故事板的样子：

在我的didSelectRowAtIndexPath中，我有这段代码：

NewViewController *WVC = [self.storyboard instantiateViewControllerWithIdentifier:@"NewViewController"];
[self.navigationController pushViewController:WVC animated:YES];

当我运行应用程序时，该应用程序看起来像：

然而，当我点击一行时，会显示详细信息，但是这样：

有人可以让我知道我哪里出错了，先谢谢。

NewViewController.m中的代码

- (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];
}

编辑:(答案） 经过大量的头部撞击和拔毛后，问题通过更换

解决了

NewViewController *WVC = [self.storyboard instantiateViewControllerWithIdentifier:@"NewViewController"];

与

NewViewController *WVC = [[NewViewController alloc] init];

老实说，我不知道为什么前一个不起作用。

如果您不需要导航栏，请使用隐藏它

[self.navigationController setNavigationBarHidden:YES];
