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
KToast.h

KToast.m

[viewController dismissViewControllerAnimated:YES completion:^{ }]; }]]; [actionSheet addAction:[UIAlertAction actionWithTitle:title1 style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) { !handler1 ? : handler1(action); }]]; [actionSheet addAction:[UIAlertAction actionWithTitle:title2 style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) { !handler2 ? : handler2(action); }]]; [viewController presentViewController:actionSheet animated:YES completion:nil]; } //MARK: 是否删除 中间弹框 + (void)showDeleteDecideWithController:(UIViewController *)viewController title:(NSString *)title sureHandler:(KAlertHandler)sureHandler { [[KToast alloc] initWithDeleteDecideWithController:viewController title:title sureHandler:sureHandler]; } - (void)initWithDeleteDecideWithController:(UIViewController *)viewController title:(NSString *)title sureHandler:(KAlertHandler)sureHandler { UIAlertController *alertVc = [UIAlertController alertControllerWithTitle:title message:nil preferredStyle:UIAlertControllerStyleAlert]; UIAlertAction *actionDone = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDestructive handler:^(UIAlertAction * _Nonnull action) { //删除 !sureHandler ? : sureHandler(action); }]; UIAlertAction *actionCancel = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) { }]; [alertVc addAction:actionDone]; [alertVc addAction:actionCancel]; [viewController presentViewController:alertVc animated:YES completion:^{ }]; } @end
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 }];
