在iOS中更改个人资料图片按钮

Question

I want to create change profile picture button like the image below. I'm a newbie in ios, I have an idea of create a view with those button and make the background opacity to 50. I'm just wondering if xcode or ios has a default function same as the shown image below.

Answer 1

Use this code:

  UIActionSheet *action=[[UIActionSheet alloc]initWithTitle:@"Change Profile Picture" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Remove Current Photo" otherButtonTitles:@"Import From Facebook",@"Import From Twitter",@"Take Photo",@"Choose From Library", nil];

 [action showInView:self.view]; 

And use below code for actionsheet button click action.

 - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
    if (buttonIndex==0)
    {
    }
    else if (buttonIndex==1) 
    {
    }
    ...
}
