  • 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。
