1诗轻、UILable
(1)常用屬性
open var text: String? // default is nil
open var font: UIFont! // default is nil (system font 17 plain)
open var textColor: UIColor! // default is labelColor
open var textAlignment: NSTextAlignment
2遥诉、UIImageView
public init(image: UIImage?, highlightedImage: UIImage?)
3董虱、UIButton
(1)常用屬性
var backgroudColor:UIColor
(2)常用方法
open func setTitle(_ title: String?, for state: UIControl.State)
open func setTitleColor(_ color: UIColor?, for state: UIControl.State)
open func setImage(_ image: UIImage?, for state: UIControl.State)
open func setBackgroundImage(_ image: UIImage?, for state: UIControl.State)
func addTarget(self,action:#selector(yourfunc),for:UIControlEvent)
4舔示、UITextField—>UITextFieldDelegate
(1)常用屬性
open var text: String?
open var textColor: UIColor?
open var font: UIFont?
open var textAlignment: NSTextAlignment
open var borderStyle: UITextField.BorderStyle
open var placeholder: String?
open var leftView: UIView?
open var rightView: UIView?
weak open var delegate: UITextFieldDelegate?
(2)代理方法
func textFieldShouldBeginEditing(_ textField: UITextField) -> Bool
func textFieldDidBeginEditing(_ textField: UITextField)
func textFieldShouldEndEditing(_ textField: UITextField) -> Bool
func textFieldDidEndEditing(_ textField: UITextField)
func textFieldDidEndEditing(_ textField: UITextField, reason: UITextField.DidEndEditingReason)
//文本發(fā)生變化時調(diào)用
func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool
func textFieldDidChangeSelection(_ textField: UITextField)
func textFieldShouldClear(_ textField: UITextField) -> Bool
func textFieldShouldReturn(_ textField: UITextField) -> Bool
5锥腻、UISwitch
(1)常用屬性
//開啟狀態(tài)的顏色
open var onTintColor: UIColor?
//正常（未開啟）狀態(tài)的顏色
open var TintColor: UIColor?
//開關(guān)的滑塊顏色
open var thumbTintColor: UIColor?
open var onImage: UIImage?
open var offImage: UIImage?
//當(dāng)前狀態(tài)
open var isOn: Bool
(2)常用方法
func addTarget(self,#selector(youract),for:UIControlEvent)
6企量、UIPageControl
(1)常用屬性
open var numberOfPages: Int
open var currentPage: Int
//其他未選中的頁碼點(diǎn)的顏色
open var pageIndicatorTintColor: UIColor?
//當(dāng)前選中的頁碼點(diǎn)的顏色
open var currentPageIndicatorTintColor: UIColor?
(2)常用方法
func addTarget(self,#selector(youract),for:UIControlEvent)
?
7和簸、UISegmentedController
(1)常用屬性
open var isMomentary: Bool // if set, then we don't keep showing selected state after tracking ends. default is NO
open var selectedSegmentIndex: Int
@available(iOS 13.0, *)
open var selectedSegmentTintColor: UIColor?
(2)常用方法
//構(gòu)造方法指定每個segment顯示的對象凳枝，創(chuàng)建的時候必須指定
public init(items: [Any]?)
func addTarget(self,#selector(youract),for:UIControlEvent)
//title
open func setTitle(_ title: String?, forSegmentAt segment: Int)
open func titleForSegment(at segment: Int) -> String?
//Image
open func setImage(_ image: UIImage?, forSegmentAt segment: Int)
open func imageForSegment(at segment: Int) -> UIImage?
//width
open func setWidth(_ width: CGFloat, forSegmentAt segment: Int)
open func widthForSegment(at segment: Int) -> CGFloat
//CGSize
open func setContentOffset(_ offset: CGSize, forSegmentAt segment: Int)
open func contentOffsetForSegment(at segment: Int) -> CGSize
open func setEnabled(_ enabled: Bool, forSegmentAt segment: Int)
open func isEnabledForSegment(at segment: Int) -> Bool
//remove and insert
open func insertSegment(withTitle title: String?, at segment: Int, animated: Bool)
open func insertSegment(with image: UIImage?, at segment: Int, animated: Bool)
open func removeSegment(at segment: Int, animated: Bool)
open func removeAllSegments()
