iOS-日期选择控件(可单独选年/年月/年月日)
说明
iOS系统提供的UIDatePicker 只能用于选择年月日,通过借鉴stackoverflow上的思路对月日图层的隐藏来达到显示年/ 年月的效果
效果展示
通过分段控制器 选择年 弹出仅有年份选择的datePicker
通过分段控制器 选择月 弹出仅有年月选择的datePicker
通过分段控制器 选择日 弹出有年月日选择的datePicker
实现的主要代码
override func layoutSubviews() {
super.layoutSubviews()
guard datePickerView.subviews.first?.subviews.first?.subviews.count == 3 else {
return
}
datePickerView.subviews.first?.subviews.first?.subviews[1].frame.origin.x = 0
datePickerView.subviews.first?.subviews.first?.subviews[0].frame.origin.x = 0
if type == .month {
datePickerView.subviews.first?.subviews.first?.subviews[0].isHidden = false
datePickerView.subviews.first?.subviews.first?.subviews[1].isHidden = false
datePickerView.subviews.first?.subviews.first?.subviews[2].isHidden = true
datePickerView.subviews.first?.subviews.first?.subviews[1].frame.origin.x += 100
} else if type == .year {
datePickerView.subviews.first?.subviews.first?.subviews[0].isHidden = false
datePickerView.subviews.first?.subviews.first?.subviews[1].isHidden = true
datePickerView.subviews.first?.subviews.first?.subviews[2].isHidden = true
datePickerView.subviews.first?.subviews.first?.subviews[0].frame.origin.x += 70
} else {
datePickerView.subviews.first?.subviews.first?.subviews[0].isHidden = false
datePickerView.subviews.first?.subviews.first?.subviews[1].isHidden = false
datePickerView.subviews.first?.subviews.first?.subviews[2].isHidden = false
}
}
