如何进行类似"Whatsapp"的半透明模态搜索?-“拍照/选择现有照片"； [英] How to do a semi-transparent modal segue like "Whatsapp" - "Take Photo/ Choose Existing Photo"

问题描述

我的想法是创建一个类似于whatsapp的半透明视图.

My idea is to create a semi-transparent view like whatsapp does.

1)我在图像视图上有一个轻击手势.

1) I have a tap gesture on image view.

2)当我点击图像视图时，将出现一层透明的视图，如whatsapp

2) When I tap on the image view, one layer of transparent view like whatsapp will appear

3)然后，我有三个按钮-选择新按钮，选择现有按钮或取消按钮.

3) I then have three button - take new, choose existing or cancel.

如何从这里继续?当我按取消"时，它应该会弹出半透明的ui视图.

How do I continue from here? When I press cancel it should pop away the semi-transparent ui view..

推荐答案

为什么不使用UIActionSheet....尝试类似...

why dont you use UIActionSheet....try something like...

UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil
                                                      delegate:self
                                             cancelButtonTitle:@"Cancel"
                                        destructiveButtonTitle:nil
                                             otherButtonTitles:@"Take photo",@"Choose existing", nil];



            actionSheet.actionSheetStyle=UIActionSheetStyleBlackTranslucent;

           [actionSheet showFromRect:[sender frame] inView:self.view animated:YES];

还可以在委托方法中实现该动作.....

also implement the action in the delegate method.....

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
    // create an image picker controller
    UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
     imagePickerController.delegate = self;

    if(buttonIndex==0)
    {
    //create image picker with source camera blah blah
    }
else if(buttonIndex==1)
    {
    //choose existing... 
    }
}
