这两个用法比较简单:
具体代码如下:
一、UISegmentedControl
1、UISegmentedControl的声明
var segment = UISegmentedControl()
2、UISegmentedControl的创建
func initSegment() {
segment = UISegmentedControl(items:["one", "two", "three", "four"])
segment.frame = CGRect(x:10.0, y:100.0, width:SCREEN_WIDTH - 20.0, height:30.0)
segment.isMomentary = true
segment.selectedSegmentIndex = 0 //设置选中的是第一个选项
segment.addTarget(self, action: action: #selector(segClick(segTapped:)), forControlEvents: .touchUpInside)
self.view.addSubview(segment)
}
3、响应方法的实现
func segClick(segTapped:UISegmentedControl) {
print("index is \(sender.selectedSegmentIndex)")
}
UIWebView
1、声明
var webView = UIWebView()
2、创建
func initWebView() {
webView.frame = CGRect(x:0, y:220, width:SCREEN_WIDTH, height:SCREEN_HEIGHT - 220)
webView.backgroundColor = UIColor.blue
let url = NSURL(string: "https://www.baidu.com/")
let request = NSURLRequest(URL: url! as URL)
webView.loadRequest(request)
self.view.addSubview(webView)
}
3、webview响应的代理方法
这里就不一一列举,可以自己点进去看看,常用的就是那几个监听的方法,如下:
func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool
func webViewDidStartLoad(webView: UIWebView)
func webViewDidFinishLoad(webView: UIWebView)
func webView(webView: UIWebView, didFailLoadWithError error: NSError?)
