ios - ios6&ios7中4寸屏和3.5寸屏UIButton和UITableview的显示方法

Question

我正在开发一个应用程序。在应用程序中，我为 ios7 和 ios6 编写了 3.5 英寸屏幕和 4 英寸屏幕的代码。我拿了一个 View Controller ；在这个 View Controller 中，我想显示两个图像，一个用于顶部，另一个用于底部。还显示登录和注销按钮以及登录 Tableview。在ios7&ios6 3.5寸屏幕和4寸屏幕上显示Top image和Bottom image两张图没有问题。这两个图像显示正确。但是没有显示按钮和 UITableview。我不明白显示 UIButton 和 UITableview 的问题在哪里。请给我想法，任何人。我是编程新手。提前致谢。

下面是我的代码。

Viewcontroller.m(适用于 ios7 和 ios6 的 3.5 英寸和 4 英寸屏幕)。

 if ([[UIScreen mainScreen] bounds].size.height == 568)  
  {

   if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7)
    {

     imgLogo=[[UIImageView alloc]initWithFrame:CGRectMake(75, 65, 162, 57)];

     imgBuilding=[[UIImageView alloc]initWithFrame:CGRectMake(8, 415, 300, 153 )];

     // Button Login for ios7 4-inches screen.

     btnLogin.frame = CGRectMake(20, 230, 127, 32);

     // Create Login for UITableview

     tableVw=[[UITableView alloc] initWithFrame:CGRectMake(0, 80, 320, 123) style:UITableViewStyleGrouped];

  }

  else
   {

   imgLogo=[[UIImageView alloc]initWithFrame:CGRectMake(75, 45, 162, 57)];

   imgBuilding=[[UIImageView alloc]initWithFrame:CGRectMake(8, 395, 300, 153 )];

   // Button Login for ios6 4-inches screen.

   btnLogin.frame = CGRectMake(20, 230, 127, 32);

   tableVw=[[UITableView alloc] initWithFrame:CGRectMake(0, 80, 320, 123) style:UITableViewStyleGrouped];

    }

   imgLogo.image=[UIImage imageNamed:@"Logo-01.png"];

   [self.view addSubview:imgLogo];

   imgBuilding.image=[UIImage imageNamed:@"image-02.png"];

   imgBuilding.alpha=0.4;      

   [self.view addSubview:imgBuilding];

   btnLogin = [UIButton buttonWithType:UIButtonTypeRoundedRect];

   [btnLogin addTarget:self action:@selector(login) forControlEvents:UIControlEventTouchDown];

   [btnLogin setBackgroundImage:[UIImage imageNamed:@"Sign-in-button.png"] forState:UIControlStateNormal];

   [self.view addSubview:btnLogin];

   // create Login tableview properties

   tableVw.dataSource = self;       
   tableVw.delegate = self;

   tableVw.backgroundColor=[UIColor clearColor];

   tableVw.scrollEnabled=NO;

   tableVw.scrollsToTop=NO;

   [self.view addSubview:tableVw];

 }

试试这个代码。我对您的代码进行了更改。

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    if ([self respondsToSelector:@selector(edgesForExtendedLayout)])
        self.edgesForExtendedLayout = UIRectEdgeNone;

    UIImageView *imgLogo;
    UIImageView *imgBuilding;
    UIButton *btnLogin = [UIButton buttonWithType:UIButtonTypeCustom];
    UITableView *tableVw;
    if ([[UIScreen mainScreen] bounds].size.height == 568){

        if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7){

            imgLogo=[[UIImageView alloc]initWithFrame:CGRectMake(75, 65, 162, 57)];
            imgBuilding=[[UIImageView alloc]initWithFrame:CGRectMake(8, 415, 300, 153 )];

            btnLogin.frame = CGRectMake(20, 230, 127, 32);

            tableVw=[[UITableView alloc] initWithFrame:CGRectMake(0, 123, 320, 100) style:UITableViewStylePlain];
        }else{
