一、简介
<<分段控件提供一栏按钮（有时称为按钮栏），但只能激活其中一个按钮。分段控件会导致用户在屏幕上看到的内容发生变化。它们常用于在不同类别的信息之间选择，或在不同的应用屏幕之间切换

<<继承关系：UISegmentedControl-->UIControl-->UIView-->UIResponder-->NSObject

格式为

1-->初始化（作用）

@property(nonatomic) UISegmentedControlStyle segmentedControlStyle NS_DEPRECATED_IOS(2_0, 7_0, "The segmentedControlStyle property no longer has any effect") __TVOS_PROHIBITED;//废弃属性（这是说明）

二、UISegmentedControl的属性(属性的顺序与苹果API一致)

1--> 初始化方法

-(instancetype)initWithItems:(nullable NSArray *)items; // items 可以是 NSStrings or UIImages. 控件的大小会自动调整为适合的内容。

2-->设置UISegmentedControl的风格

@property(nonatomic) UISegmentedControlStyle segmentedControlStyle NS_DEPRECATED_IOS(2_0, 7_0, "The segmentedControlStyle property no longer has any effect") __TVOS_PROHIBITED;//废弃属性

3-->设置在点击后是否恢复原样

@property(nonatomic,getter=isMomentary) BOOL momentary;          //如果设置，则在跟踪结束后，我们不会继续显示选定的状态。默认是 NO

4-->获取总选项数

@property(nonatomic,readonly) NSUInteger numberOfSegments;

5-->是否根据segment的内容改变segment的宽度

@property(nonatomic) BOOL apportionsSegmentWidthsByContent NS_AVAILABLE_IOS(5_0);

6-->在指定索引插入一个选项并设置题目

-(void)insertSegmentWithTitle:(nullable NSString *)title atIndex:(NSUInteger)segment animated:(BOOL)animated;

7-->在指定索引插入一个选项并设置图片

-(void)insertSegmentWithImage:(nullable UIImage *)image  atIndex:(NSUInteger)segment animated:(BOOL)animated;

8-->移除指定索引的选项

-(void)removeSegmentAtIndex:(NSUInteger)segment animated:(BOOL)animated;

9-->移出所有segment

-(void)removeAllSegments;

10-->设置指定索引的题目

-(void)setTitle:(nullable NSString *)title forSegmentAtIndex:(NSUInteger)segment;

11-->获取指定索引选项的标题

-(nullable NSString *)titleForSegmentAtIndex:(NSUInteger)segment;
12-->设置指定索引的图片

-(void)setImage:(nullable UIImage *)image forSegmentAtIndex:(NSUInteger)segment;

13-->获取指定索引选项的图片

-(nullable UIImage *)imageForSegmentAtIndex:(NSUInteger)segment;
14-->设置Item的宽度

-(void)setWidth:(CGFloat)width forSegmentAtIndex:(NSUInteger)segment;
15-->获取指定索引选项的宽度

-(CGFloat)widthForSegmentAtIndex:(NSUInteger)segment;
16-->设置内容偏移

-(void)setContentOffset:(CGSize)offset forSegmentAtIndex:(NSUInteger)segment;
17-->获取内容偏移

-(CGSize)contentOffsetForSegmentAtIndex:(NSUInteger)segment;
18-->设置segment是否可用

-(void)setEnabled:(BOOL)enabled forSegmentAtIndex:(NSUInteger)segment;       // default is YES

19-->判断指定索引选项是否可选

-(BOOL)isEnabledForSegmentAtIndex:(NSUInteger)segment;

20-->设置默认选择项索引

@property(nonatomic) NSInteger selectedSegmentIndex;

21-->设置segments的颜色

@property(null_resettable,nonatomic,strong) UIColor *tintColor;
22-->设置背景图

-(void)setBackgroundImage:(nullable UIImage *)backgroundImage forState:(UIControlState)state barMetrics:(UIBarMetrics)barMetrics NS_AVAILABLE_IOS(5_0) UI_APPEARANCE_SELECTOR;

23-->获取背景图

-(nullable UIImage *)backgroundImageForState:(UIControlState)state barMetrics:(UIBarMetrics)barMetrics NS_AVAILABLE_IOS(5_0) UI_APPEARANCE_SELECTOR;
24-->设置标签之间分割线的图案

-(void)setDividerImage:(nullable UIImage *)dividerImage forLeftSegmentState:(UIControlState)leftState rightSegmentState:(UIControlState)rightState barMetrics:(UIBarMetrics)barMetrics NS_AVAILABLE_IOS(5_0) UI_APPEARANCE_SELECTOR;

25-->获取标签之间分割线的图案

-(nullable UIImage *)dividerImageForLeftSegmentState:(UIControlState)leftState rightSegmentState:(UIControlState)rightState barMetrics:(UIBarMetrics)barMetrics  NS_AVAILABLE_IOS(5_0) UI_APPEARANCE_SELECTOR;
26-->通过Attribute字符串属性字典设置标签标题

-(void)setTitleTextAttributes:(nullable NSDictionary *)attributes forState:(UIControlState)state NS_AVAILABLE_IOS(5_0) UI_APPEARANCE_SELECTOR;
27-->获取Attribute字符串属性字典

-(nullable NSDictionary *)titleTextAttributesForState:(UIControlState)state NS_AVAILABLE_IOS(5_0) UI_APPEARANCE_SELECTOR;

28-->设置标签内容的偏移量

-(void)setContentPositionAdjustment:(UIOffset)adjustment forSegmentType:(UISegmentedControlSegment)leftCenterRightOrAlone barMetrics:(UIBarMetrics)barMetrics NS_AVAILABLE_IOS(5_0) UI_APPEARANCE_SELECTOR;
29-->获取自定义偏移量

-(UIOffset)contentPositionAdjustmentForSegmentType:(UISegmentedControlSegment)leftCenterRightOrAlone barMetrics:(UIBarMetrics)barMetrics NS_AVAILABLE_IOS(5_0) UI_APPEARANCE_SELECTOR;
