iPad2相机代码和iPhone4一样吗?
我正在为 iPad 制作一个应用程序,并且希望能够使用 iPad 2 摄像头(如果可用)。加载iPad相机的代码与iPhone 4的代码相同吗?我在这个应用程序的 iPhone 版本上运行了相同的代码,但没有 iPad 2 来测试,并且模拟器无法帮助我使用相机。下面是我必须确定相机是否可用,然后在弹出窗口中加载相机或加载库
基本上我只需要知道 iPad 2 相机是否支持下面的行,或者我需要使用其他东西吗?
[self presentModalViewController:imagePickerController animated:YES];
我希望相机是全屏而不是弹出窗口。
- (IBAction) takePhoto:(id)sender {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
imagePickerController = [[UIImagePickerController alloc] init];
[imagePickerController setDelegate:self];
[imagePickerController setSourceType:UIImagePickerControllerSourceTypeCamera];
imageView.contentMode = UIViewContentModeScaleAspectFit;
[self presentModalViewController:imagePickerController animated:YES];
} else {
imagePickerController = [[UIImagePickerController alloc] init];
[imagePickerController setDelegate:self];
[imagePickerController setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
imageView.contentMode = UIViewContentModeScaleAspectFit;
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:imagePickerController];
[popover setDelegate:self];
[popover presentPopoverFromBarButtonItem:sender
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
}
}
I am making an app for the iPad and want to be able to use the iPad 2 camera if available. Is the code to load the iPad camera the same as for the iPhone 4? I have this same code working on the iPhone version of this app, but do not have an iPad 2 to test with and simulator can't help me with the camera. Below is what I have to determine if camera is available and then to load camera or load library in popup
Basically I just need to know if the line below is supported by the iPad 2 camera or do I need to use something else?
[self presentModalViewController:imagePickerController animated:YES];
I want camera to be full screen and not in a popup.
- (IBAction) takePhoto:(id)sender {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
imagePickerController = [[UIImagePickerController alloc] init];
[imagePickerController setDelegate:self];
[imagePickerController setSourceType:UIImagePickerControllerSourceTypeCamera];
imageView.contentMode = UIViewContentModeScaleAspectFit;
[self presentModalViewController:imagePickerController animated:YES];
} else {
imagePickerController = [[UIImagePickerController alloc] init];
[imagePickerController setDelegate:self];
[imagePickerController setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
imageView.contentMode = UIViewContentModeScaleAspectFit;
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:imagePickerController];
[popover setDelegate:self];
[popover presentPopoverFromBarButtonItem:sender
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
}
}

是的,如果
self
是 UINavigationController,那么这确实有效。我知道这一点是因为我在我的应用程序中也做了同样的事情。我不确定其他 UIViewControllers,但按理说它也能工作。Yes this works, for sure if
self
is a UINavigationController. I know this because I do the same in my app. I'm not sure for other UIViewControllers, but it stands to reason that it will also work.
