简单的封装UIAlertController的两个常用样式

项目里面本来有弹框选项的工具,但是是用的UIAlertView,过期的产品总得慢慢淘汰,最近项目里面的功能经常要用到删除操作,和相片选取操作,所以得弄个选项框工具,方便开发,因为时间比较赶,所以随便先封装了两个最近特长用到的两个样式

1,一种是从底部弹出选项提示框,可以传入两个选项,其中默认有了"取消"一项,因为拍照是有"拍照"和'从相册选"两个选择,所以封装这个工具用就比较方便了

2,一种是从中间弹出的提示选框,用在是否确定删除的场景

代码比较简单,这里就不做解释了,直接复制黏贴了,以后慢慢封装,慢慢来补充,作为自己的笔记

    [alertVc addAction:actionCancel];

使用就超级简单了

[KToast showSheetActionWithViewController:self title:@"请选择拍照方式" action1Title:@"拍照" action2Title:@"从相册选" action1Handler:^(UIAlertAction *action){
        //拍照操作
        
    } action2Handler:^(UIAlertAction *action){
        //从相册选操作
        
    }];

[KToast showDeleteDecideWithController:self title:@"确定删除宝贝?" sureHandler:^(UIAlertAction *action) {
        //删除操作
    }];
