首先当然是引入该文件 再初始化一下嘛
#import "TestView.h"
@property (nonatomic, strong) TestView *TestView;
在需要的view上面直接使用 需要传入几个值
/**
一些需要的值
@param titles 标题数组
@param Ncolor 正常背景色
@param Scolor 隐藏背景色
@param Lcolor 滚动线背景色
@param index 默认位置
*/
_TestView = [[TestView alloc]initWithFrame:CGRectMake(0, 550, SCREEN_WIDTH, 48)];
NSArray *title = @[@"豆奶",@"饼干",@"冰糖",@"豆浆",@"饼干",@"冰糖",@"豆浆"];
[_TestView MakesegTitle:title titlenormalColcor:[UIColor grayColor] titleseletedColor:[UIColor orangeColor] lineColor:[UIColor orangeColor] selectedSegmentIndex:3];
_TestView.Block = ^(NSString *itemname, NSInteger index) {
NSLog(@"%@--%ld",itemname,index);
};
[self.view addSubview:_TestView];
Block回调返回点击位置做其他事件处理
这里还有一个方法是外部控件 比如配合使用的UIscrollowView 可以在适当地方调用该方法改变UISegmentedControl显示位置
[_TestView selectedSegmentIndex:seg.selectedSegmentIndex];
看看方法吧:.h文件
#import <UIKit/UIKit.h>
#import "UIView+Extension.h"//扩展文件
typedef void (^clickblock)(NSString *itemname,NSInteger index);
@interface TestView : UIView
@property(nonatomic, copy)clickblock Block;
/**
一些需要的值
@param titles 标题数组
@param Ncolor 正常背景色
@param Scolor 隐藏背景色
@param Lcolor 滚动线背景色
@param index 默认位置
*/
-(void)MakesegTitle:(NSArray*)titles titlenormalColcor:(UIColor *)Ncolor titleseletedColor:(UIColor*)Scolor lineColor:(UIColor*)Lcolor selectedSegmentIndex:(NSInteger)index;
//外部控件调用这个控制位置
-(void)selectedSegmentIndex:(NSInteger )index;
@end
.m文件
