UIDatePicker
//UIDatePicker属于UIContrl 类似于UIButton 可以运用于12306时间限制
let date = UIDatePicker(frame:CGRect(x: 50, y: 400, width: 400, height: 200))
date.datePickerMode = .Time
self.view.addSubview(date)
date.addTarget(self, action: #selector(change(_:)), forControlEvents: .ValueChanged)
func change(da:UIDatePicker){
print(da.date)
}
UIPickerView
思路 几列 每列里面包含了几行 每行里面的数据
//UIPickerView属于UIView 类似UITableView 用协议UIPickerViewDataSource,UIPickerViewDelegate实现数据和触发事件
let picker = UIPickerView(frame: CGRect(x: 50, y: 100, width: 300, height: 200))
picker.dataSource = self
picker.delegate = self
self.view.addSubview(picker)
实现协议
func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int {
return 3
}
func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return 8
}
func pickerView(pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusingView view: UIView?) -> UIView {
if component == 0{
let brownView = UIImageView()
brownView.image = UIImage(named: "图")
return brownView
}
else if component == 1{
let redView = UIView()
redView.backgroundColor = UIColor.redColor()
return redView
}
else{
let yellowiew = UIView()
yellowiew.backgroundColor = UIColor.yellowColor()
return yellowiew
}
}
func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
print("\(component):","\(row)")
}
