初始化的方法

 //一次性初始化多個control，items可以是圖片或者是文字array，系統(tǒng)會自動控制每個單元的大小
 //也可通過正常View的初始化進行
 - (instancetype)initWithItems:(NSArray *)items; 

事件添加

 //通過UIControl的方法來設(shè)置，當改變segments的時候通過事件UIControlEventValueChanged，
 //通過action來處理事件
 [self.mySegmentedControl addTarget:self
                     action:@selector(myAction:)
           forControlEvents:UIControlEventValueChanged];

Segmented Controls的內(nèi)容設(shè)置

 //通過索引設(shè)置以及獲取Title和Image          
 - (void)setTitle:(NSString *)title forSegmentAtIndex:(NSUInteger)segment;
 - (NSString *)titleForSegmentAtIndex:(NSUInteger)segment;
 - (void)setImage:(UIImage *)image forSegmentAtIndex:(NSUInteger)segment;
 - (UIImage *)imageForSegmentAtIndex:(NSUInteger)segment;

Segmented Controls Segments的設(shè)置

 //在索引點插入一個新的標題的segment
 - (void)insertSegmentWithTitle:(NSString *)title atIndex:(NSUInteger)segment animated:(BOOL)animated;
 //在索引點插入一個新的圖片的segment
 - (void)insertSegmentWithImage:(UIImage *)image  atIndex:(NSUInteger)segment animated:(BOOL)animated;
 - (void)removeSegmentAtIndex:(NSUInteger)segment animated:(BOOL)animated;
 - (void)removeAllSegmens;
 //Segment的數(shù)量
 @property(nonatomic,readonly) NSUInteger numberOfSegments;  
 //被選中的索引
 @property(nonatomic) NSInteger selectedSegmentIndex;

Segmented Controls顯示和行為設(shè)置

 //默認值為NO，即點擊后保持選中狀態(tài)，如果設(shè)置為YES則，只是短暫的顯示選中狀態(tài)
 @property(nonatomic,getter=isMomentary) BOOL momentary;
 //通過索引調(diào)整每個segment的width，如果設(shè)置為0.0則表示自動調(diào)整大小，默認為0.0
 - (void)setWidth:(CGFloat)width forSegmentAtIndex:(NSUInteger)segment;
 - (CGFloat)widthForSegmentAtIndex:(NSUInteger)segment;
 //通過索引調(diào)整文字或者圖片在segment的offset，默認為（0,0）
 - (void)setContentOffset:(CGSize)offset forSegmentAtIndex:(NSUInteger)segment;
 - (CGSize)contentOffsetForSegmentAtIndex:(NSUInteger)segment;
 //設(shè)置segment是否能選中
 - (void)setEnabled:(BOOL)enabled forSegmentAtIndex:(NSUInteger)segment;       
 - (BOOL)isEnabledForSegmentAtIndex:(NSUInteger)segment;
 //是否根據(jù)內(nèi)容的大小自動調(diào)整寬度
 @property(nonatomic) BOOL apportionsSegmentWidthsByContent NS_AVAILABLE_IOS(5_0);

自定義的外觀

 //設(shè)置UISegmentedControl的邊框，分隔線，文字，點擊后的顏色
 @property(nonatomic,retain) UIColor *tintColor;
 //獲取和設(shè)置背景圖片，通過UIControlState和barMetrics的進行設(shè)置和獲取，主要需要先設(shè)置
 //UIControlStateNormal才會有效果
 - (UIImage *)backgroundImageForState:(UIControlState)state barMetrics:(UIBarMetrics)barMetrics
 - (void)setBackgroundImage:(UIImage *)backgroundImage forState:(UIControlState)state barMetrics:(UIBarMetrics)barMetrics
 //設(shè)置分割線的圖片樣式，首先需要設(shè)置UIControlStateNormal不管左邊還是右邊，
 //設(shè)置完成后再調(diào)用設(shè)置方法，根據(jù)UIControlState顯示分割線
 - (void)setDividerImage:(UIImage *)dividerImage forLeftSegmentState:(UIControlState)leftState rightSegmentState:(UIControlState)rightState barMetrics:(UIBarMetrics)barMetrics
 - (UIImage *)dividerImageForLeftSegmentState:(UIControlState)leftState rightSegmentState:(UIControlState)rightState barMetrics:(UIBarMetrics)barMetric      //設(shè)置Title的樣式，包括 font, text color,  shadow。通過NSAttributedString.h里面的鍵值對
 - (void)setTitleTextAttributes:(NSDictionary *)attributes forState:(UIControlState)state NS_AVAILABLE_IOS(5_0) UI_APPEARANCE_SELECTOR;
 - (NSDictionary *)titleTextAttributesForState:(UIControlState)state NS_AVAILABLE_IOS(5_0) UI_APPEARANCE_SELECTOR;
 //調(diào)整title和image的位置，通過給定的segment 
 - (void)setContentPositionAdjustment:(UIOffset)adjustment forSegmentType:(UISegmentedControlSegment)leftCenterRightOrAlone barMetrics:(UIBarMetrics)barMetrics NS_AVAILABLE_IOS(5_0) UI_APPEARANCE_SELECTOR; 
 - (UIOffset)contentPositionAdjustmentForSegmentType:(UISegmentedControlSegment)leftCenterRightOrAlone barMetrics:(UIBarMetrics)barMetrics NS_AVAILABLE_IOS(5_0) UI_APPEARANCE_SELECTOR;
