How to draw a simple line without using Interface Builder in iphone sdk?

Question

我想在视图控制器中绘制一个简单的行，而不使用“接口”构建器。

Answer 1

If you only want to draw horizontal or vertical line, you can just use UIView.

UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(<startingX>, <startingY>, <width>, <height>)];
lineView.backgroundColor = <desiredColor>;

//assume self is UIViewController or its sublcass
[self.view addSubview:lineView];
[lineView release];

Answer 2

Try this question . I know this references InterfaceBuilder, but you can dynamically add your custom view using Obj-C like mentioned here .
