Swift - UIView,UILabel,UIButton,UIImageView

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。
