swift实现简易计算器项目
<p>本文实例为大家分享了swift实现简易计算器的具体代码，供大家参考，具体内容如下</p><p>首先在storyboard中搭建出界面</p>

<p>接着上viewcontroller代码</p>
<div class="jb51code"><pre class="brush:cpp;">import UIKit
class ViewController: UIViewController {
@IBOutlet weak var result: UILabel!
var n1: String = ""
var n2: String = ""
var n3: String = ""
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
@IBAction func didClick(sender: UIButton) {
let temp = sender.currentTitle
if temp == "AC" {
n1 = ""
n2 = ""
result.text = "0"
return
}
else if temp == "+" || temp == "-" || temp == "*" || temp == "/" {
n1 = result.text!
n2 = ""
n3 = temp!
return
}
else if temp == "=" {
var result1: Double = 0
println("n1:"+n1+" n2:"+n2)
switch n3 {
case "+":
result1 = (n1 as NSString).doubleValue + (n2 as NSString).doubleValue
case "-":
result1 = (n1 as NSString).doubleValue - (n2 as NSString).doubleValue
case "*":
result1 = (n1 as NSString).doubleValue * (n2 as NSString).doubleValue
case "/":
result1 = (n1 as NSString).doubleValue / (n2 as NSString).doubleValue
default:
result1 = 0
}
result.text = "\(result1)"
n3 = ""
return
}
if n3 != "" {
n2 = n2 + temp!
result.text = n2
}else {
n1 = n1 + temp!
result.text = n1
}
}
}</pre></div>
<p>最后效果图</p>
