Swift - UIView,UILabel,UIButton,
学习Swift没少查资料，但是发现网上都是对一些基础语法的介绍，还有些看不明白的，博主觉得么，没必要看的那么详细，等使用中自然就会懂了。但是使用的时候，我们最常用的UIView,UILabel,UIButton,UIImageView却没有说怎么用，今天博主就来介绍这些我们常用的控件怎么用，有了这些控件的使用方法，普通界面我们已经能够随手搭出来了
代码统一放，博主简单写了个工程
import UIKit
class ViewController: UIViewController {
var myView = UIView()
var myLabel = UILabel()
var myButton = UIButton()
var myImageView = UIImageView()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.toCreatAUIView()
self.toCreatAUILabel()
self.toCreatAUIButton()
self.creatAUIImageView()
}
/**
toCreatAUIView
*/
func toCreatAUIView () {
myView.frame = CGRectMake(0, 0, 320, 568)
myView.backgroundColor = UIColor.blueColor()
self.view.addSubview(myView)
}
/**
toCreatAUILabel
*/
func toCreatAUILabel() {
myLabel.frame=CGRectMake(10, 20, 300, 60);
myLabel.text = "This is a UILabel!"
myLabel.backgroundColor = UIColor.redColor()
myLabel.textColor = UIColor.whiteColor()
myLabel.textAlignment = NSTextAlignment.Center
myLabel.layer.borderWidth = 1
myView.addSubview(myLabel)
}
/**
toCreatAUIButton
*/
func toCreatAUIButton() {
myButton.frame = CGRectMake(10, 100, 300, 60);
myButton.setTitle("This is a UIButton", forState: .Normal)
myButton.setTitleColor(UIColor.whiteColor(), forState: .Normal)
myButton.setImage(UIImage.init(named: ""), forState: .Normal)
myButton.layer.borderWidth = 1
myButton.layer.cornerRadius = 5
myButton.layer.borderColor = UIColor.blackColor().CGColor
myButton.addTarget(self, action: #selector(self.myButtonAction(_:)), forControlEvents: .TouchUpInside)
myView.addSubview(myButton)
}
/**
myButtonAction
- parameter btn: An AlertView
*/
func myButtonAction(btn:UIButton) {
let myAlertView = UIAlertView()
myAlertView.title = "alertView"
myAlertView.message = "This is a UIAlertView"
myAlertView.addButtonWithTitle("Cancel")
myAlertView.addButtonWithTitle("Ok")
myAlertView.cancelButtonIndex = 0
myAlertView.show()
}
/**
creatAUIImageView
*/
func creatAUIImageView() {
myImageView.frame = CGRectMake(10, 200, 300, 300);
myImageView.image = UIImage.init(named: "fire.jpg")
myImageView.userInteractionEnabled = true
myView.addSubview(myImageView)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
打完收工，想学到更多的Swift相关的知识，欢迎关注，博主比较懒，重实用，比较难理解的概念暂时都会放放，先达到能做项目的程度。
