自动调整大小无法以编程方式工作 [英] Autoresizing Not Working Programmatically

问题描述

我想创建一个UIView，它将根据iPhone屏幕尺寸调整其宽度，并且应将其保留在视图底部.

I want to create a UIView which will resize it's width according to iPhone Screen size and it should be remain at bottom of view.

我使用情节提要创建了一个新项目，并添加了以下代码.

I created fresh project with storyboard and add below code.

这是我的代码

-(void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:true];

    UIView *box = [[UIView alloc]initWithFrame:CGRectMake(0, 448, 320, 120)];
    [box setBackgroundColor:[UIColor redColor]];

    [box setAutoresizingMask:UIViewAutoresizingFlexibleHeight];
    [box setAutoresizingMask:UIViewAutoresizingFlexibleWidth];
    [box setAutoresizingMask:UIViewAutoresizingFlexibleTopMargin];
    [box setAutoresizingMask:UIViewAutoresizingFlexibleLeftMargin];
    [box setAutoresizingMask:UIViewAutoresizingFlexibleRightMargin];

    [self.view addSubview:box];
}

自动布局已关闭.

如果我通过应用界面生成器中的自动调整大小功能来做同样的事情，那么它工作得很好.

If I do same thing by apply autoresizing from interface builder then it's working perfectly.

我不明白为什么它不起作用.

I didn't understand any reason for why it's not working.

推荐答案

从我这边的小错误. 我的代码是正确的.

Little mistake from my side. My code is correct.

问题与xCode 6.1有关，在启动屏幕中，我们具有xCode 6中的xib文件，因此我必须从常规设置"->应用程序图标"和启动图像"中删除对它的引用，并使用断言目录而不是launchscreen.xib及其它开始工作....

The issue is related to xCode 6.1, in launch screen we have xib file from xCode 6 so i have to remove reference of it from General Setting-> App Icon and Launch Images and use Assert Catalog instead of launchscreen.xib and it start working....

无论如何，感谢您对我的问题的答复.
