将uiview作为子视图添加到主视图中 [英] adding uiview as a subview to the main view

问题描述

我想为小尺寸添加 UIView 作为现有视图的子视图。

i want to add an UIView for small size as a subview to existing view.

我有一个 UIViewController 用一个nib名称推送，这是主视图，我试图创建一个 UIView 的对象并分配它视图控制器的 viewDidLoad 方法中具有以下代码的维度

i have a UIViewController pushed with a nib name which is the main view, i am trying to create an object of UIView and alloc it with dimension with the following code in the viewcontroller's viewDidLoad methoad

UIView *view = [[UIView alloc] init];

但想法并不是建议 UIView 如果我强行键入并运行则抛出错误

but the idea is not suggesting the alloc on UIView and throwing an error if i forcefully type and run

请帮我解决这个问题

推荐答案

在上面的答案中添加一些内容（相当重要）;

To add something (rather important) to the answers above;

CGRect frame = CGRectMake(x, y, width, height); // Replacing with your dimensions
UIView *view = [[UIView alloc] initWithFrame:frame];

然后，你想要实际将它添加到superview（假设视图是self.view）

Then, you want to actually add it to the superview (assuming the view is self.view)

[self.view addSubview:view];
