Objective c 自动调整面具是如何工作的?

Objective c 自动调整面具是如何工作的?,objective-c,ios,cocoa-touch,autoresizingmask,Objective C,Ios,Cocoa Touch,Autoresizingmask,我已经找到了很多关于自动调整大小的信息,但是没有一个能够解决我的问题。我有一个ViewController(RAViewController),它在loadView方法中调用视图,如下所示: - (void)loadView { // Set Navigation Bar Title self.navigationItem.title = @"RA"; // Add Background view self.view = [[UIView alloc] init

我已经找到了很多关于自动调整大小的信息,但是没有一个能够解决我的问题。我有一个ViewController(RAViewController),它在loadView方法中调用视图,如下所示:

- (void)loadView
{
    // Set Navigation Bar Title
    self.navigationItem.title = @"RA";

    // Add Background view
    self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    // Add RAView
    RAView *rAView = [[RAView alloc] initWithFrame:self.view.frame Controller:self];
    [self.view rAView];
}
它调用的视图(RAView)如下所示:

- (id)initWithFrame:(CGRect)frame Controller:(RAViewController *)Controller
{
    self = [super initWithFrame:frame];
    if (self) {
        // Initialization code
        self.autoresizesSubviews = YES;
        self.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
        self.backgroundColor = [[UIColor alloc] initWithRed:1.0 green:1.0 blue:1.0 alpha:1.0];

        controller = Controller;

        // Draw Architecture View
        [self drawArchitectureView];
    }
return self;
}

-(void)drawArchitectureView {
    UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(10, 10, self.frame.size.width - 20, 50);

    [button setBackgroundColor:[UIColor grayColor]];
    [button setTitle:@"Overview" forState:UIControlStateNormal];

    [self addSubview:button];
}

由于某些原因,当设备处于横向时,我无法使用自动调整大小掩码来调整按钮宽度。非常感谢您的帮助。

如果您希望它保持相同的高度,但只需保持完全居中,从左到右10.0,请尝试:

-(void)drawArchitectureView {
    UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(10, 10, self.frame.size.width - 20, 50);

    button.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleRightMargin;

    [button setBackgroundColor:[UIColor grayColor]];
    [button setTitle:@"Overview" forState:UIControlStateNormal];

    [self addSubview:button];
}

我相信你需要在UIButton上设置自动重设屏幕。试过了。按钮最终被从屏幕上移开,这不是我所期望的,这意味着我不太理解它是如何工作的。这也不是self.autoresizesSubviews=YES的要点所以我不必这样做?您尝试将按钮autoresizeMask设置为什么?您是否尝试过UIViewAutoResizingFlexibleLeLeftMargin | UIViewAutoresizingFlexibleRightMargin?此外,autoresizesSubviews属性默认为YES,因此无需像您一样进行设置。这允许子视图的autoresizingMask属性工作。如果不是,就不会调整大小。好吧,因为我把它拿出来了。是的,它使按钮居中,但没有我想要的那么长。由于某些原因,高度和宽度值没有交换。
