This article will explain in detail how to set the appearance of the button in the iOS11 application view beautification button. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

To put it bluntly, to beautify the button is to set the properties of the button. There are two ways to set the properties of the button: one is to use the property inspector in the editing interface; the other is to use the code to set it. The following will mainly explain how to use code to set up buttons.

1. Set the appearance of the button

Setting the appearance of the button is actually setting the button's title, image, and so on. Table 2-1 lists some of the properties commonly used to set the appearance of buttons.

[example 2 # 2] A button will be added to the main view below. The title of this button is I am button, and the color of the title is black. The code is as follows:

Import UIKit

Class ViewController: UIViewController {

Override func viewDidLoad () {

Super.viewDidLoad ()

/ / Do any additional setup after loading the view, typically from a nib.

/ / add button object

Let button=UIButton (frame: CGRect (x: 135, y: 241, width: 97, height: 30))

Button.setTitle ("I am Button", for: UIControlState.normal) / / set the title

Button.setTitleColor (UIColor.black, for: UIControlState.normal) / / sets the color of the title

Self.view.addSubview (button)

}

……

}

When you run the program at this point, you will see the effect shown in figure 2.3.
