相亲神器记录Swift1.2

这个简单APP是用swfit1.2写的，主要重点是:1.点击键盘return键可退出键盘。 2.各个控件值的传递。

Storyboard界面设计：

View代码：

 1 import UIKit
 2
 3 class ViewController: UIViewController ,UITextFieldDelegate{
 4
 5     @IBOutlet weak var name: UITextField!
 6     @IBOutlet weak var gender: UISegmentedControl!
 7     @IBOutlet weak var birthday: UIDatePicker!
 8     @IBOutlet weak var heightNumber: UISlider!
 9     @IBOutlet weak var height: UILabel!
10     @IBOutlet weak var hasProperty: UISwitch!
11     @IBOutlet weak var result: UITextView!
12
13     override func viewDidLoad() {
14         super.viewDidLoad()
15         name.delegate = self//点击return退出键盘
16     }
17     override func didReceiveMemoryWarning() {
18         super.didReceiveMemoryWarning()
19         // Dispose of any resources that can be recreated.
20     }
21
22     @IBAction func heightChanged(sender: AnyObject) {
23         var slider = sender as! UISlider
24         var i = Int(slider.value)   //Float转换为Int
25         slider.value = Float(i)     //转换操作
26         height.text = "\(i)厘米"    //随着滑块改变label的值
27     }
28
29     @IBAction func okTapped(sender: AnyObject) {
30         let genderText = gender.selectedSegmentIndex==0 ? "高富帅" : "白富美"
31         let gregorian = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)
32         let now = NSDate()
33         birthday.maximumDate = NSDate()//防止年龄为负数
34         let components = gregorian?.components(NSCalendarUnit.CalendarUnitYear, fromDate: birthday.date, toDate: now, options: NSCalendarOptions(0))//计算年龄
35
36         let age = components!.year//得到年龄
37         let hasPropertyText = hasProperty.on ? "有房":"没房"  //switch值的数据
38
39         result.text = "\(name.text),\(age)岁,\(genderText),身高\(height.text!),\(hasPropertyText),求交往!"
40
41     }
42
43     //UITextFiledDelegate,点击return使键盘退出
44     func textFieldShouldReturn(textField: UITextField) -> Bool{
45         textField.resignFirstResponder()
46         return true
47     }
48 }

在这代码里需要注意的是,由于swift语言的改变，需要在age和height.text的赋值或显示中在其后加上！，否则会报错。
