ios - 弹出 View 以选择图像

我想创建一个类似于下图的示例，但可以从“照片库”中选择图像或使用相机拍摄照片（例如facebook应用）。该视图是内置视图还是我需要创建自定义视图？

最佳答案

所以你想要一个UIActionSheet吗？

做这个：

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];

然后在clickedButtonAtIndex中执行以下操作：

- (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];
}
