小控件的简单使用
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
//Segmented Control
let title = ["xx", "ss", "qq"]
let seg = UISegmentedControl(items: title)
seg.frame = CGRect(x: 100, y: 100, width: 300, height: 100)
seg.addTarget(self, action: #selector(didchoose(_:)), forControlEvents: .ValueChanged)
// seg.momentary = true
self.view.addSubview(seg)
//Slider
let slider = UISlider(frame: CGRect(x: 300, y: 300, width: 100, height: 100))
slider.continuous = false//设置为拖动不计算滑动条的值
slider.maximumValue = 100
slider.minimumValue = 0
slider.addTarget(self, action: #selector(didslider(_:)), forControlEvents: .ValueChanged)
self.view.addSubview(slider)
//Switch
let swi = UISwitch(frame: CGRect(x: 200, y: 400, width: 100, height: 100))
swi.onTintColor = UIColor.redColor()
swi.thumbTintColor = UIColor.greenColor()
swi.tintColor = UIColor.brownColor()
swi.addTarget(self, action: #selector(didswitch(_:)), forControlEvents: .ValueChanged)
self.view.addSubview(swi)
//Page Control
let page = UIPageControl(frame: CGRect(x: 200, y: 300, width: 100, height: 100))
page.addTarget(self, action: #selector(didpage(_:)), forControlEvents: .ValueChanged)
page.currentPageIndicatorTintColor = UIColor.redColor()
page.pageIndicatorTintColor = UIColor.cyanColor()
page.numberOfPages = 4
self.view.addSubview(page)
//Stepper
let ste = UIStepper(frame: CGRect(x: 300, y: 500, width: 100, height: 100))
ste.maximumValue = 100.00
ste.minimumValue = 20.00
ste.addTarget(self, action: #selector(didstep(_:)), forControlEvents: .ValueChanged)
self.view.addSubview(ste)
// webView
let url = NSURL(string: "http://www.baidu.com")
let webview = UIWebView(frame: self.view.bounds)
let request = NSURLRequest(URL: url!)
webview.loadRequest(request)
self.view.addSubview(webview)
}
//小控件触发的方法
func didchoose(sender: UISegmentedControl){
print(sender.selectedSegmentIndex)
}
func didslider(sender: UISlider){
print(sender.value)
}
func didswitch(sender:UISwitch){
print(sender.on)
}
func didpage(sender: UIPageControl){
print(sender.currentPage)
}
func didstep(sender: UIStepper){
print(sender.value)
}
}
pickerView
import UIKit
class ViewController: UIViewController,UIPickerViewDelegate,UIPickerViewDataSource {
override func viewDidLoad() {
super.viewDidLoad()
//创建pike对象，调用协议并显示
let pike = UIPickerView(frame: CGRect(x: 0, y: 0, width: self.view.bounds.size.width, height: 200))
pike.dataSource = self
pike.delegate = self
self.view.addSubview(pike)
//与pike像，但是其左右为显示当前时间
let date = UIDatePicker(frame: CGRect(x: 0, y: 300, width: self.view.frame.size.width, height: 200))
self.view.addSubview(date)
}
//实现协议方法，4列
func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return 4
}
//3行
func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int {
return 3
}
//拖动选择时输出列号，行号
func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
print(component,row)
}
//设置每一个的内容
func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return "ss"
}
//重用，如果为空则创建
func pickerView(pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusingView view: UIView?) -> UIView {
if let v1 = view{
v1.backgroundColor = UIColor.redColor()
return v1
}else{
let v2 = UIView()
v2.backgroundColor = UIColor.brownColor()
return v2
}
}
}
UIGestureRecognizer／PKHUD插件
import UIKit
import PKHUD//在一些需要等待的时候显示（显示完隐藏）提醒，或是警告
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
//单点触碰手势
let gestrue = UITapGestureRecognizer(target: self, action: #selector(didgesture(_:)))
HUD.show(.Label("请稍等"))//在显示之前会有提示
HUD.hide(afterDelay: 3)//在3秒后隐藏
self.view.addGestureRecognizer(gestrue)
//滑动手势，上下左右
let left = UISwipeGestureRecognizer(target: self, action: #selector(didswipe(_:)))
left.direction = .Left
self.view.addGestureRecognizer(left)
let right = UISwipeGestureRecognizer(target: self, action: #selector(didswipe1(_:)))
right.direction = .Right
self.view.addGestureRecognizer(right)
let up = UISwipeGestureRecognizer(target: self, action: #selector(didswipe3(_:)))
up.direction = .Up
self.view.addGestureRecognizer(up)
let down = UISwipeGestureRecognizer(target: self, action: #selector(didswipe2(_:)))
down.direction = .Down
self.view.addGestureRecognizer(down)
}
//单点触碰手势触发方法
func didgesture (sender: UIGestureRecognizer){
//触碰位置
let location = sender.locationInView(self.view)
print(location)
//设置提示类对象，并设置类型／标题／信息
let alercrl = UIAlertController(title: "瞅啥瞅", message: "你丑", preferredStyle: .Alert)
//设置提示的文本框与键盘类型
alercrl.addTextFieldWithConfigurationHandler { (textfile) in
textfile.placeholder = "bingo"
textfile.keyboardType = .Default
}
//设置点击动作
let action = UIAlertAction(title: "ok", style: .Default) { (action) in
print("ok")
let a = alercrl.textFields![0]
print(a.text!)
}
let action1 = UIAlertAction(title: "cancel", style: .Cancel) { (action1) in
print("cancel")
}
//在提示控制器中添加点击动作
alercrl.addAction(action)
alercrl.addAction(action1)
self.presentViewController(alercrl, animated: true, completion: nil)
}
//上下左右触发的事件
func didswipe(sender: UISwipeGestureRecognizer){
print("left")
}
func didswipe1(sender: UISwipeGestureRecognizer){
print("right")
}
func didswipe2(sender: UISwipeGestureRecognizer){
print("down")
}
func didswipe3(sender: UISwipeGestureRecognizer){
print("up")
}
}
