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
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor whiteColor];
// 加载底部视图
[self setUpBottomView];
}

}
// 文字改变事件
- (void)textChangeAction:(NSString *)str
{
NSLog(@"代理文字正在改变:%@",str);
}
// 键盘完成事件
- (void)clickKeyBordCompleteAction:(NSString *)str
{

}
//点击关闭事件
- (void)closeButtonAction
