1.使用方法

1.导入头文件:#import "GFChooseView.h"
2.遵守代理 <GFChooseViewDelegate>
3.创建

 self.chooseView = [[GFChooseView alloc]initWithFrame:CGRectMake(0, kScreenH, kScreenW, kScreenH)];
    _chooseView.delegate = self;
    
    [self.view addSubview:_chooseView];

4.GFChooseViewDelegate代理方法

• 4.1点击加号事件
• -(void)clickAddButtonAction:(NSString *)str;
• 4.2点击减号事件
• (void)clickReduceButtonAction:(NSString *)str;
• 4.3 文字改变事件
• (void)textChangeAction:(NSString *)str;
• 4.4 键盘完成事件
• (void)clickKeyBordCompleteAction:(NSString *)str;
• 4.5点击关闭事件
• (void)closeButtonAction;
• 4.6 点击确定事件
• (void)confirmButtonAction;
• 4.7 规格参数
• 4.8(void)clickBtnIndexWithTag:(NSInteger)index;

2.代码
