Which delegate function of UIDocumentInteractionControllerDelegate is called when document is completely loaded on the preview?
Just to share, I have already tried :
- (void)documentInteractionControllerDidEndPreview:(UIDocumentInteractionController *)controller
And this is called when we close the preview.
This is a bit of a work around as there doesn't appear to be a completion handler for this in the documentation, as far as I can tell.
-(void)presentDocument:(NSURL*)url{
UIDocumentInteractionController *docInteration = [UIDocumentInteractionController interactionControllerWithURL:url];
docInteration.UTI = #"com.adobe.pdf";
docInteration.delegate = self;
[docInteration presentPreviewAnimated:YES];
}
-(void)documentInteractionControllerDidEndPreview: (UIDocumentInteractionController *)controller{
[self.navigationController dismissViewControllerAnimated:NO completion:nil];
}
- (UIViewController *)documentInteractionControllerViewControllerForPreview:(UIDocumentInteractionController *)controller{
UIViewController * vc = [[UIViewController alloc]init];
[self.navigationController presentViewController:vc
animated:YES
completion:^{
//This is ran once the document animation has completed
}];
return vc;
}
Hope this helps.

I have a UIAlertView that launches an email and a messages screen. When a user clicks on the Alert's button, both views open, however, they do not close.
I have a tried adding:
-(void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
[self dismissModalViewControllerAnimated:YES];
}
to the body of the class, however, it did not help.
Here is how the email is presented:
[viewController presentViewController:email animated:YES completion:nil];
Edit Here is the entire code I am using to present the email:
//send email...
-(void)sendEmail{
//mail composer
Class mailClass = (NSClassFromString(#"MFMailComposeViewController"));
if(mailClass != nil){
if([mailClass canSendMail]){
//get the current view controller from the App Delegate
apptester_appDelegate *appDelegate = (apptester_appDelegate *)[[UIApplication sharedApplication] delegate];
UIViewController *viewController = [appDelegate getViewController];
MFMailComposeViewController *email = [[MFMailComposeViewController alloc] init];
email.mailComposeDelegate = self;
//navigation bar color depends on iOS7 or lower...
if(floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1){
[[email navigationBar] setTintColor:[UIColor blackColor];
}else{
[[email navigationBar] setBarTintColor:[UIColor blackColor]];
}
//show the model view...
[viewController presentViewController:email animated:YES completion:nil];
}
}
}
Has anyone else experienced this error?
This may not be relevant, but this app has a tab bar.
Make sure you have set delegate for mail controller
mail.mailComposeDelegate = viewController;
Also try this as well,
[viewController.tabBarController presentViewController:email animated:YES completion:nil];
Have you try this method and pass "controller" instead of self:
-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
[controller dismissViewControllerAnimated:YES completion:nil];
}
Thanks!
It is the responsibility of presenting controller to dismiss the modal view. Make sure you implement the delegate of the modal in the presenting controller.
Two things:
1) Make sure you set the mailComposeDelegate on the MFMailComposeViewController before you present it.
2) In your mailComposeController:didFinishWithResult:error: method, you should do:
[controller dismissModalViewControllerAnimated:YES];
I'm a bit confused, this isn't a question on how to dismiss a UIImagePickerController, it's more of a "why did that work" type of question. I am working in iOS7.
Looking online at the apple documentation (this link: https://developer.apple.com/library/ios/documentation/AudioVideo/Conceptual/CameraAndPhotoLib_TopicsForIOS/Articles/TakingPicturesAndMovies.html#//apple_ref/doc/uid/TP40010406-SW6), I came across the following code for dismissing a UIImagePickerController:
[[picker parentViewController] dismissModalViewControllerAnimated: YES];
Edit: I know that that method was deprecated, so instead I tried the following, and that did not work either:
[[picker parentViewController] dismissViewControllerAnimated:YES completion:NULL];
Those didn't work for me. This however did work:
[picker dismissViewControllerAnimated:YES completion:NULL];
Is the apple documentation wrong? or just outdated?
Why does the second bit of code work, because from my understanding, its the parent view controllers job to dismiss something like a popover or in this case a UIImagePickerController
Thank you.
Edit: This is how I am presenting the UIImagePickerController, the UITapGestureRecognizer calls the first method which then calls the second.
- (IBAction)captureMoment:(UITapGestureRecognizer *)sender {
[self startCameraCaptureFromViewController:self usingDelegate:self];
}
- (BOOL)startCameraCaptureFromViewController:(UIViewController *)controller
usingDelegate:(id <UIImagePickerControllerDelegate, UINavigationControllerDelegate>)delegate {
if (delegate == nil || controller == nil || [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] == NO) {
return NO;
}
UIImagePickerController *camera = [[UIImagePickerController alloc] init];
camera.sourceType = UIImagePickerControllerSourceTypeCamera;
camera.allowsEditing = NO;
camera.delegate = delegate;
[controller presentViewController:camera animated:YES completion:NULL];
return YES;
}
There are 2 methods that worked for me
Use picker.presentingViewController instead of picker.parentViewController, answer by rmaddy
Use the following code in the imagePickerControllerDidCancel:, [picker dismissViewControllerAnimated:YES completion:NULL];
Here is the code in its entirety, this is placed in the UIViewController that presents the UIImagePickerController:
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker.presentingViewController dismissViewControllerAnimated:YES completion:NULL];
}
The method dismissModalViewControllerAnimated has been deprecated since iOS6. The new method you are using is the correct one.
This worked in iOS6, so not sure what the issue is.
inside my UINavigationController (ioNavController) I present the UIImagePickerController with the Following:
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.modalInPopover = YES;
imagePicker.modalPresentationStyle = UIModalPresentationCurrentContext;
[self presentViewController:imagePicker animated:NO completion:^{ }];
in my UIImagePickerControllerDelegate (which does get called)I have the Following:
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
//This does not work
[ioNavController dismissViewControllerAnimated:YES completion:^{ /* Cleanup if Needed */ }];
//This does not work
[[picker parentViewController] dismissViewControllerAnimated:YES completion:^{ /* Cleanup if Needed */ }];
//This does not work
[picker removeFromParentViewController];
// This presents a new view on the Nav Controller. It shows the new view ontop of the ImagePicker. Image Picker View does not repond to touches.
[ioNavController pageToSelect:0];
}
Your delegate it's in the same controller that called the imagepicker? The same controller that called presentViewController should call the line below, and the imagepicker will be removed correctly.
[self dismissViewControllerAnimated:YES completion:nil]; //self here it's the same reference that called presentViewController
let me know if worked or helped.
The UIImagePickerController will remove itself when you use this code:
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)pPicker {
[pPicker dismissViewControllerAnimated:YES completition:NULL]; }
I'm fairly new to this, so bear with me. I have 2 errors left to fix in my code. In both cases my instance methods are not found:
-(IBAction)goFlipSide {
NSLog(#"goFlipSide has been called:");
FlipsideViewController *controller = [[FlipsideViewController alloc] initWithNibName:#"FlipsideViewController" bundle:nil];
controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentViewController:controller animated:YES];
[controller release];
}
- (void)flipsideViewControllerDidFinish:(FlipsideViewController *)controller {
[self dismissViewControllerAnimated:YES];
//This method gets fired when the user clicks done on the modal FlipsideViewController. This is different
//than the viewWillAppear.
self.navigationController.navigationBarHidden = TRUE;
/*
if (self.goViewSuccess == TRUE) {
//if the goViewSuccess boolean is set to YES - then we can load the load the goViewController
NSLog(#"goViewSuccess is YES");
[self loadGoViewController];
}
*/
}
Both instance methods not found are: presentViewController: and dismissViewControllerAnimated:.
What class is self? Those methods are only found on UIViewController. The full selectors are:
presentViewController:animated:completion:
dismissViewControllerAnimated:completion:
Try adding the completion block argument.
The code is supposed to be this
[self dismissViewControllerAnimated:YES completion:nil];
or if you want something when its done,
[self dismissViewControllerAnimated:YES completion:^{
//do stuff
}];
And for the other one
[self presentViewController:controller animated:YES completion:nil];
I have a View Controller which displays a table view. The VC calls another VC to display the send SMS view to the user, the code for this SMS VC is:
- (void) sendSMSWithBody: (NSString*) body andRecipients: (NSArray*) recipients
{
MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
if ([MFMessageComposeViewController canSendText])
{
controller.messageComposeDelegate = self;
controller.body = body;
controller.recipients = recipients;
[[UIApplication sharedApplication].delegate.window.rootViewController addChildViewController:self];
[self presentModalViewController:controller animated:YES];
}
}
- (void) messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
[self dismissModalViewControllerAnimated:YES];
[[UIApplication sharedApplication].delegate.window.rootViewController removeFromParentViewController];
}
(I know the call to sharedApplication is a bit hacky, but it will suffice for now. the rootViewController is a UINavigationController which has its root controller set to the table view controller)
I am invoking the SMS VC from the table VC like so:
- (void ) viewDidAppear:(BOOL)animated
{
static BOOL presentedSMSVC = NO;
if (!presentedSMSVC)
{
SendSMSController *sendSMS = [[SendSMSController alloc] init];
[sendSMS sendSMSWithBody:#"body"
andRecipients:[NSArray arrayWithObject:#"123456789"]];
presentedRegisterVC = YES;
}
}
The problem is that after the user sends the SMS the table view cells are not displaying.
I thought maybe I need to refresh the view/table so I added a protocol callback from the 2nd VC to the first which gets invoked when the user sends the SMS, and then within the callback call [self.tableView reloadData] But it made no difference.
So I got rid of the intermediary class and edited the table view to display the SMS view directly like this:
- (void ) viewDidAppear:(BOOL)animated
{
static BOOL presentedRegisterVC = NO;
if (!presentedRegisterVC)
{
MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
if ([MFMessageComposeViewController canSendText])
{
controller.messageComposeDelegate = self;
controller.body = #"body";
controller.recipients = [NSArray arrayWithObject:#"12345678"];
[self presentModalViewController:controller animated:NO];
}
}
}
- (void) messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
[self dismissModalViewControllerAnimated:NO];
}
But now the MFMessageComposeViewController doesn't dismiss (although messageComposeViewController:didFinishWithResult: does get called)
What is the problem with both approaches? Thanks
For the second variant, I changed to:
[self presentViewController: controller animated: YES completion:nil];
[self dismissViewControllerAnimated:YES completion:nil];
And that worked, haven't tried applying to the first method.
I faced a similar UI issue.
My case was: The controller, let's say controller A, in which I had written the code to present and dismiss the MFMessageComposeController, was not being used directly as the active controller rather I was using A.view as a subview over another controller, say controller B. So writing the following was distorting the view:
[self presentViewController:composeVC animated:YES completion:nil];
But then writing the following solved my issue:
[self.customTabbarNavigation presentViewController:composeVC animated:YES completion:nil];
The customTabbarNavigation, was the controller B, ans was actually the navigation controller which was active when controller A's view was visible.
Same change had to be made for dismissing the composeVC.
