iPhone:我的程序可以使用imagepicker API访问摄像头吗?

你用 UIImagePickerController 直接:

UIImagePickerController *thePicker = [[UIImagePickerController alloc] init];
thePicker.delegate = thePickerDelegate;
thePicker.sourceType = UIImagePickerControllerSourceTypeCamera;

//Here you would present thePicker modally, and release it after this
//It will be deallocated when you remove it from screen
[anotherViewController presentModalViewController: thePicker animated:NO];
[thePicker release];

在 thePickerDelegate ,实施

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo;

这个 image UIImagePickerController 要在拍摄一张照片后消失,您可以在此处触发此操作,并在上面的模式示例中通过调用

[thePicker dismissModalViewControllerAnimated: NO];
