iOS - UIView 无法横向调整大小

一些非常奇怪的事情发生在我身上(至少对我来说很奇怪) 我有一个视图控制器(fileManagerViewController),它的 UI 基本上是一个空视图 顶部有一个工具栏。我用 IB 制作了这个 UI。在工具栏上我有一些按钮,其中两个按钮用于在两个视图之间切换。我必须切换的两个视图的 UI 是由代码编写的。

  • 在 FileManagerViewController 的 viewDidLoad 中,我写了这

-(void) viewDidLoad {
  [super viewDidLoad];
  fileManagerTableView = [[FileManagerTableView alloc] init];
  fileManagerGridView  = [[FileManagerGridView alloc] init];
  self.view.autoresizingMask = UIViewAutoresizingFlexibleHeight
                              |UIViewAutoresizingFlexibleWidth;
  self.view.autoresizesSubviews=YES;
  self.view addSubview:fileManagerTableView.view];
  [self.view addSubview:fileManagerGridView.view];
  [fileManagerTableView.view setHidden:YES];
}
  • 两个 loadView 方法,

    -(void) loadView {
        CGRect fileGridViewFrame  = CGRectMake(0.0, 50.0, 1024,768);
 fileGridView = [[[AQGridView alloc] 
                              initWithFrame:fileGridViewFrame] 
                               autorelease];  

 fileGridView.dataSource=self;
 fileGridView.delegate=self;
 fileGridView.autoresizingMask=UIViewAutoresizingFlexibleWidth|
                                       UIViewAutoresizingFlexibleHeight
 fileGridView.autoresizesSubviews=YES;
 fileGridView.bounces;
 fileGridView.backgroundColor = [[UIColor colorWithPatternImage:
                                        [UIImage imageNamed:@"bg.png"]]];
 [self.fileGridView reloadData];
 self.view = fileGridView;
}

    -(void) loadView {
        CGRect fileTableViewFrame  = CGRectMake(0.0, 44.0, 1024,768);
 fileGridView = [[[UITableView alloc] 
                              initWithFrame:fileTableViewFrame] 
                               autorelease];  

 fileGridView.dataSource=self;
 fileGridView.delegate=self;
 fileGridView.autoresizingMask=UIViewAutoresizingFlexibleWidth|
                                       UIViewAutoresizingFlexibleHeight
 fileGridView.autoresizesSubviews=YES;
 fileGridView.bounces;
 fileGridView.backgroundColor = [[UIColor colorWithPatternImage:
                                        [UIImage imageNamed:@"bg.png"]]];
 [self.fileGridView reloadData];
 self.view = fileGridView;
}

结果是,正如我所说,奇怪的是,如果应用程序以纵向模式启动,那么所有的工作都如我所期望的那样,这两个视图在纵向和横向模式下渲染得很好。如果应用程序在设备横向启动时,视图不会填满整个屏幕。看看这个 屏幕截图

something really weird it's happening to me (at least weird for me)
I have a view controller (fileManagerViewController) the UI of this is basically an empty view
with a toolbar on top. I made this UI with IB. on the toolbar i have some buttons, two of those buttons are used to switch between two views. The UI for the two views that I've to switch was made by code.

  • Inside the viewDidLoad of FileManagerViewController I wrote this

-(void) viewDidLoad {
  [super viewDidLoad];
  fileManagerTableView = [[FileManagerTableView alloc] init];
  fileManagerGridView  = [[FileManagerGridView alloc] init];
  self.view.autoresizingMask = UIViewAutoresizingFlexibleHeight
                              |UIViewAutoresizingFlexibleWidth;
  self.view.autoresizesSubviews=YES;
  self.view addSubview:fileManagerTableView.view];
  [self.view addSubview:fileManagerGridView.view];
  [fileManagerTableView.view setHidden:YES];
}
  • those are the two loadView methods

    -(void) loadView {
        CGRect fileGridViewFrame  = CGRectMake(0.0, 50.0, 1024,768);
 fileGridView = [[[AQGridView alloc] 
                              initWithFrame:fileGridViewFrame] 
                               autorelease];  

 fileGridView.dataSource=self;
 fileGridView.delegate=self;
 fileGridView.autoresizingMask=UIViewAutoresizingFlexibleWidth|
                                       UIViewAutoresizingFlexibleHeight
 fileGridView.autoresizesSubviews=YES;
 fileGridView.bounces;
 fileGridView.backgroundColor = [[UIColor colorWithPatternImage:
                                        [UIImage imageNamed:@"bg.png"]]];
 [self.fileGridView reloadData];
 self.view = fileGridView;
}

    -(void) loadView {
        CGRect fileTableViewFrame  = CGRectMake(0.0, 44.0, 1024,768);
 fileGridView = [[[UITableView alloc] 
                              initWithFrame:fileTableViewFrame] 
                               autorelease];  

 fileGridView.dataSource=self;
 fileGridView.delegate=self;
 fileGridView.autoresizingMask=UIViewAutoresizingFlexibleWidth|
                                       UIViewAutoresizingFlexibleHeight
 fileGridView.autoresizesSubviews=YES;
 fileGridView.bounces;
 fileGridView.backgroundColor = [[UIColor colorWithPatternImage:
                                        [UIImage imageNamed:@"bg.png"]]];
 [self.fileGridView reloadData];
 self.view = fileGridView;
}

the result is, as i said weird, if the app start in portrait mode all works as I expect the two view s are rendered well in portrait and landscape mode. If the app is started with the device in landscape orientation the views don't fill the entire screen. Have a look a this

在 IB 内部的布局控件中,使用调整大小控件。要访问上述控件,请打开检查器中的第三个选项卡 (Cmd+3)

另外,在 viewWillAppear 方法内部,在视图上调用 setNeedsDisplay。

Inside of IB, in the layout controls, play with the resize controls. To access the said controls, open the third tab in inspector (Cmd+3)

Also, inside of your viewWillAppear method, call setNeedsDisplay on your view.
