有人知道如何在相机模式下启用UIImagePickerController上的相册按钮吗?就像iphone上的相机应用程序如何在图像和视频拍摄之间切换一样,还有按钮来查看照片库?

这可以通过以下几行完成:
- (void) navigationController: (UINavigationController *) navigationController willShowViewController: (UIViewController *) viewController animated: (BOOL) animated {
if (imagePickerController.sourceType == UIImagePickerControllerSourceTypePhotoLibrary) {
UIBarButtonItem* button = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera target:self action:@selector(showCamera:)];
viewController.navigationItem.rightBarButtonItems = [NSArray arrayWithObject:button];
} else {
UIBarButtonItem* button = [[UIBarButtonItem alloc] initWithTitle:@"Library" style:UIBarButtonItemStylePlain target:self action:@selector(showLibrary:)];
viewController.navigationItem.leftBarButtonItems = [NSArray arrayWithObject:button];
viewController.navigationItem.title = @"Take Photo";
viewController.navigationController.navigationBarHidden = NO; // important
}
}
- (void) showCamera: (id) sender {
imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
}
- (void) showLibrary: (id) sender {
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}

我担心这不能以那么简单的方式完成(只需启用或禁用某些魔术功能)。对于一些简单的要求,您可以使用cameraOverlayView和showsCameraControls来实现。
如果您想在照片/视频模式之间切换,我想您可以查看此演示:http://developer.apple.com/library/ios/#samplecode/AVCam/Introduction/Intro.html

这是一个示例应用程序和非常简单的库,可让您像Facebook一样获取“拍照”或“从库中选择”。 https://github.com/fulldecent/FDTake
