彈出式視圖選擇圖像

Question

我想創建一個像下面的圖像的例子，而是從圖片庫中選擇圖像或使用相機拍攝圖片（如facebook應用程序）。這個視圖是內置的還是我需要創建一個自定義視圖？

Answer 1

所以，你要一個UIActionSheet？

這樣做：

UIActionSheet *actionSheet = [[UIActionSheet alloc] 
            initWithTitle:@"What do you want to do?" 
            delegate:self 
            cancelButtonTitle:@"Cancel" 
            destructiveButtonTitle:nil 
            otherButtonTitles:@"Camera", @"Photos", nil]; 
    [actionSheet showInView:self.view]; 
    [actionSheet release]; 

然後在clickedButtonAtIndex做這樣的事情：

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { 
    UIImagePickerController *picker = [[UIImagePickerController alloc] init]; 
    picker.delegate = self; 

    if ([[actionSheet buttonTitleAtIndex:buttonIndex] isEqualToString:@"Camera"]) { 
     picker.sourceType = UIImagePickerControllerSourceTypeCamera; 
    } 
    else if ([[actionSheet buttonTitleAtIndex:buttonIndex] isEqualToString:@"Photos"]) { 
     picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
    } 
    [self presentModalViewController:picker animated:YES]; 
    [picker release]; 
}
