iOS 無限添加的標題滑塊

標籤：control   turn      com   添加   selector   WAD   字型   分享   

先上個

 

 

 

自己寫了無限滑塊的類 繼承UIView 

直接使用 init 方法 可以定義每個標題 的顏色 底線 顏色 選中的顏色 和frame 標題的font

 

直接上代碼：

EJ_sliderHeader.h 

#import <UIKit/UIKit.h>

 

@interface EJ_sliderHeader : UIView

 

-(instancetype)initWithArray:(NSArray*)Data WithSliderColor:(UIColor*)slidercolor WithTitleColor:(UIColor*)titleColor WithtitleFont:(UIFont*)font WithBlock:(void(^)(NSInteger))Block;

 

/**

 無限延伸的滑塊標題

 

 @param frame 整個空間frame

 @param Data string數組

 @param slidercolor 底線和選中標題顏色

 @param titleColor 標題顏色

 @param font 標題字型

 @param Block 回調方法

 @return 執行個體

 */

-(instancetype)initWithFrame:(CGRect)frame WithArray:(NSArray*)Data WithSliderColor:(UIColor*)slidercolor WithTitleColor:(UIColor*)titleColor WithtitleFont:(UIFont*)font WithBlock:(void(^)(NSInteger))Block;

 

 

 

@property(nonatomic,copy) void(^clickToSendBack)(NSInteger index) ;

 

 

/**

 跳轉到指定位置

 

 @param index 下標代表要選中的標題

 */

-(void)changeIndex:(NSInteger)index ;

-(void)indexPathRowAdd ;

-(void)indexPathRowCut ;
