Ios 弹出视图以选择图像

我想创建一个如下图所示的示例，但可以从照片库中选择一张图片，或者用相机拍照（如facebook应用程序）。此视图是内置的还是需要创建自定义视图

那么你想要一份UIActionSheet

这样做：

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];

然后在ClickedButtonIndex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];
}

你想要一份行动表

这样做：

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];

然后在ClickedButtonIndex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];
}
