1、代码集合中涉及的控件有：

按钮、操作表、图像控件UIImageView、文本框UITextField、 警告框UIAlertView、 选择控件UISegmentControl、开关按钮 UISwitch、进度条UIProgressView、滑块UiSlider、选择框UI。

2、 关于其他控件的用法，后续更新......

3、 若查阅， windows OS，请在本页面按键control + F， 输入查找内容，MAC os,按键 command + F，输入查找内容。

4、源码如下：

    }
    
    
    
    
    
    
    
    
    
    
    
    ///----选择控件

    func segcChanged(segc: UISegmentedControl)
    {
        print("选择的文字为");
        print(segc.titleForSegmentAtIndex(segc.selectedSegmentIndex))
    }
    
    
    
    
    /*下面的控件有：button，textview， textfieled，*/
    
    func UI_TextField()
    {

        ///---设置清除按钮
        textField.clearButtonMode = UITextFieldviewmode.Always;
        
        self.view.addSubview(textField);
    }
    
    func UI_TextView()
    {
        ///---设置位置
        var cgr = CGRect(x:10,width: 300,height: 100);
        var textView = UITextView(frame:cgr);
        textView.layer.borderWidth = 1;
        textView.layer.borderColor = UIColor.grayColor().CGColor;
        
        textView.editable = true;
        textView.textColor = UIColor.greenColor();
        textView.font = UIFont(name: "Zapfino",size: 10);
        
        textView.dataDetectorTypes = UIDataDetectorTypes.PhoneNumber;
        
        
        self.view.addSubview(textView);
    }
    
    
    func UI_Switch()
    {
        var cgr = CGRect(x:10,height: 100);
        var m_switch = UISwitch(frame:cgr);
        m_switch.on = true;
        m_switch.addTarget(self,action: Selector("m_switchChanged"),forControlEvents: UIControlEvents.ValueChanged);
        
        
        
        self.view.addSubview(m_switch);
    }
    func m_switchChanged()
    {
        print("这里是开关的选择事件");
    }
    
    /*  图像控件 UIImageView    */
    func UI_ImageView()
    {
        ///--设置图像
        let imageView = UIImageView(image: UIImage(named: "image"));
        ///--设置位置
        imageView.frame = CGRectMake(10,10,100,100);
        <pre name="code" class="plain">import UIKit

class ImageViewAnimat:UIViewController
{
    var imageView:UIImageView!
    
    override func viewWillAppear(animated: Bool) {
        super.viewWillAppear(animated);
        imageView.startAnimating();
    }
    override func viewWillDisappear(animated: Bool) {
        super.viewWillAppear(animated);
        imageView.stopAnimating();
    }
    override func viewDidLoad() {
        super.viewDidLoad();
        imageView = UIImageView();
        imageView.frame = CGRectMake(10,100);
        ///---设置动画图片
        imageView.animationImages = [UIImage(named: "image1")!,UIImage(named:"image2")!];
        ///---设置切换速率,1s 一次
        imageView.animationDuration = 1;
        self.view.addSubview(imageView);
    }
    
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
}
     

5、补上 关于使用 控件 UIImageView实现动画的代码：

import UIKit

class ImageViewAnimat:UIViewController
{
    var imageView:UIImageView!
    
    override func viewWillAppear(animated: Bool) {
        super.viewWillAppear(animated);
        imageView.startAnimating();
    }
    override func viewWillDisappear(animated: Bool) {
        super.viewWillAppear(animated);
        imageView.stopAnimating();
    }
    override func viewDidLoad() {
        super.viewDidLoad();
        imageView = UIImageView();
        imageView.frame = CGRectMake(10,1s 一次
        imageView.animationDuration = 1;
        self.view.addSubview(imageView);
    }
    
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
 }

6、微调器 UIStepper

代码如下：

import UIKit

class ViewController: UIViewController {

    ///---新增代码
    var stepper:UIStepper!;
    var label:UILabel!;
    
    
    override func viewDidLoad() {
        super.viewDidLoad()
        /*  微调器 */
        super.viewDidLoad();
        stepper = UIStepper();
        stepper.center = self.view.center;
        ///设置范围与初始值
        stepper.maximumValue = 100;
        stepper.minimumValue = 1;
        stepper.value = 11;
        ///--设置每次 增减的值
        stepper.stepValue = 1;
        ///---设置stepper可以按住不放来连续更改值
        stepper.continuous = true;
        ///---设置stepper是否循环（到最大值时在增加数值从最小值开始）
        stepper.wraps = true;
        
        ///---设置stepper的事件
        stepper.addTarget(self,action: "StepperClicked",forControlEvents: .ValueChanged);
        ///---显示控件
        self.view.addSubview(stepper);
        
        
        ///----设置label的位置
        label = UILabel(frame: CGRectMake(100,190,300,30));
        ///---设置label的值
        label.text = "当前值为:" + String(stepper.value);
        ///--显示控件
        self.view.addSubview(label);
        
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
    
    ///---stepper 事件函数
    func StepperClicked()
    {
        label.text = "当前值为:\(stepper.value)";
    }

}

7、滚动视图的创建

在图片大道屏幕容纳不下的时候，UIKit框架中提供了UIScrollView类实现滚动视图，可以使用手指滚动屏幕来方便浏览整个页面。代码如下：

 ///---自定义代码开始----
        var scrollView = UIScrollView();
        scrollView.frame = self.view.bounds;
        var imageview = UIImageView(image: UIImage(named: "host"));
        scrollView.contentSize = imageview.bounds.size;
        scrollView.addSubview(imageview);
        self.view.addSubview(scrollView);
        ///---自定义代码结束----

滚动条的风格可以由属性indicatorStyle指定，indicatorStyle值如下：

UIScrollViewIndicaStyle.Default 默认滚动样式，为白色

UIScrollViewIndicaStyle.Black 黑色样式的滚动

UIScrollViewIndicaStyle.White 白色样式的滚动
