i am using the following code for the mail composer sheet in iPad application. I used the same code for iPhone. It worked.
I am writing the game in iPad using cocos2d. The game is in landScape mode. The control in EmailScene is stopping at [picker presentModalViewController:picker animated:YES]; It is not giving any error. Should I change my code for iPad ?
#interface EmailScene : CCScene <MFMailComposeViewControllerDelegate>
{
MFMailComposeViewController *picker;
}
-(void)displayComposerSheet;
#end
#implementation EmailScene
- (id) init {
self = [super init];
if (self != nil) {
[self displayComposerSheet];
}
return self;
}
// Displays an email composition interface inside the application. Populates all the Mail fields.
-(void)displayComposerSheet
{
[[CCDirector sharedDirector] pause];
picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
//Fill in the email as you see fit
NSArray *toRecipients = [NSArray arrayWithObject:#"srikanth.rongali786#gmail.com"];
[picker setToRecipients:toRecipients];
//display the view
[[[CCDirector sharedDirector] openGLView] addSubview:picker.view];
[[CCDirector sharedDirector] stopAnimation];
//When I commented the following two lines the mail page is opening.
//[picker presentModalViewController:picker animated:YES];
//[picker release];
}
But, the problem is my game is in landscape mode and the mail sheet is displayed in portrait mode.
Thank you.
You are using -presentModalViewController:… wrongly. This method should be called on the topmost view controller before the "picker" is presented.
[topmostViewController presentModalViewController:picker animated:YES];
(You shouldn't add picker.view as a subview of the -openGLView either.)

On iOS 7 only, the navigation bar in my app does not respond to any touches after a UIImagePickerController is used and then dismissed (whether a pic has been selected or not). The screen below the navigation bar functions as normal, but it is now impossible to navigate Back in the app; the user is stuck on this screen.
I am launching the UIImagePickerController from code, though the rest of the app is laid out in storyboards.
UIImagePickerController *mediaUI = [[UIImagePickerController alloc] init];
mediaUI.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
mediaUI.mediaTypes = [NSArray arrayWithObject:(NSString *) kUTTypeImage];
mediaUI.allowsEditing = NO;
mediaUI.delegate = self;
[controller presentModalViewController: mediaUI animated: YES];
Thanks in advance for any help.
I hope you are performing these steps correctly!
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[picker dismissViewControllerAnimated:YES completion:NULL];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:NULL];
}
And when you are calling
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:NULL];
Cheers!
I noticed that the log was showing "Unbalanced calls to begin/end appearance transitions for" the launching controller. I was launching the image picker controller immediately from another controller when it appeared. This works OK on iOS 8 but there needs to be a delay on iOS 7. I fixed it by calling my method after a brief delay:
[self performSelector:#selector(takePicture) withObject:nil afterDelay:.1];
I am developing multiplayer for my game and I have encountered following issue
I am using Cocos 2d 2.1 , iOS 6 and following code to show matchmaker (Landscape orientation)
AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];
[[GCHelper sharedInstance] findMatchWithMinPlayers:2 maxPlayers:4 viewController:[app navController] delegate:self];
And thats how it appears
Following code is used for that function
- (void)findMatchWithMinPlayers:(int)minPlayers maxPlayers:(int)maxPlayers
viewController:(UIViewController *)viewController
delegate:(id<GCHelperDelegate>)theDelegate {
if (!gameCenterAvailable) return;
matchStarted = NO;
self.match = nil;
self.presentingViewController = viewController;
delegate = theDelegate;
[presentingViewController dismissModalViewControllerAnimated:NO];
GKMatchRequest *request = [[[GKMatchRequest alloc] init] autorelease];
request.minPlayers = minPlayers;
request.maxPlayers = maxPlayers;
GKMatchmakerViewController *mmvc =
[[[GKMatchmakerViewController alloc] initWithMatchRequest:request] autorelease];
mmvc.matchmakerDelegate = self;
[presentingViewController presentViewController:mmvc animated:YES completion:nil];
}
is this code in HelloWorldLayer? if so is that the first layer that the director calls? I have the same problem but it's fixes if I follow strictly the cocos2d template that was created for me. Meaning that I use the IntroLayer as the initial layer and from there it transitions into the HelloWorldLayer where I have the game center code. I think it has something to do with the director being loaded too late but I'm not sure
This happens when you try to push on a UIViewController, but you only have a UIView in your app, and no UIViewController. Let me guess, you do not have a rootViewController.
If you are working from the EAGLView template, you must declare a UIViewController for the UIView. This can be as simple as,
- (void) applicationDidFinishLaunching:(UIApplication *)application
{
window.rootViewController = [[UIViewController alloc] init];
window.rootViewController.view = glView; // MUST SET THIS UP,
// NOW THE EAGLView HAS A UIViewController.
[glView startAnimation];
}
Then, anytime you want to push on one of those GameKit UIViewControllers, use the presentViewController method of your Window object's rootViewController
For example:
[self.window.rootViewController presentViewController:vc animated:TRUE completion:^(void){puts("DONE");} ] ;
The bugginess will go away and the window will be correctly formed.
Here is the set up of my view:
When the UIBarButtonItem is clicked, it should bring up a UIImagePickerController. I have to do this using a UIPopoverController, which is invoked by clicking on the "reset" button, because it is necessary on the iPad. Here is my code:
-(IBAction) btnReset:(id)sender {
[self chooseImage];
}
-(void) chooseImage {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
imagepicker = [[UIImagePickerController alloc] init];
imagepicker.allowsEditing = NO;
imagepicker.delegate = self;
imagepicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagepicker.navigationBar.opaque = true;
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
popoverController = [[UIPopoverController alloc] initWithContentViewController:imagepicker];
[popoverController presentPopoverFromBarButtonItem:reset permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];
} else {
[self presentModalViewController:imagepicker animated:YES];
}
}
}
However, when this is called, the view crashes with the error:
'NSInvalidArgumentException', reason: '-[UIPopoverController presentPopoverFromRect:inView:permittedArrowDirections:animated:]: Popovers cannot be presented from a view which does not have a window.'
What am I doing wrong? Thank you in advance.
It looks like you are trying to create a popover on an item which is not on the view hierarchy. If this method is being invoked by your button then change the method header to -(void) chooseImage:(id)sender and try presenting the popover from the UIBarButton you have on your toolbar.
Also if you are using ARC (which it looks like you are) you have to hold on to your UIPopover otherwise it will be released when it is still required see this stack overflow post. You may already be doing this but I thought I would raise it as a I can't see if/how you have specified your popoverController.
I am writing a game in cocos2d. I want to add MFMailComposeViewController to the scene.
So, when I touch a CcLabel in the scene the mail sheet is opened.
#interface EmailScene : CCScene <MFMailComposeViewControllerDelegate>
{
MFMailComposeViewController *picker;
}
-(void)displayComposerSheet;
#end
#implementation EmailScene
- (id) init {
self = [super init];
if (self != nil) {
[self displayComposerSheet];
}
return self;
}
-(void)displayComposerSheet
{
[[CCDirector sharedDirector] pause];
picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
NSArray *toRecipients = [NSArray arrayWithObject:#"srikanth.rongali786#gmail.com"];
[picker setToRecipients:toRecipients];
[[[CCDirector sharedDirector] openGLView] addSubview:picker.view];
[[CCDirector sharedDirector] stopAnimation];
}
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
[[CCDirector sharedDirector] resume];
CCScene *Scene = [CCScene node];
CCLayer *Layer = [GameWinScreen node];
[Scene addChild:Layer];
[picker.view removeFromSuperview];
[[CCDirector sharedDirector] startAnimation];
[picker dismissModalViewControllerAnimated:YES];
[[CCDirector sharedDirector] replaceScene:Scene];
}
#end

But, the problem is my game is in landscape mode. So, I need the mail sheet to display in landscape mode. But, here the mail sheet is displayed in portrait mode. And the keyboard is appearing in landscape mode. But, the mail composure sheet is in portrait mode.
And how can we change the "sent from my iPhone" to "Sent From My iPad"
Thank you.

You can try to manually rotate view...:
CGAffineTransform landscapeTransform = CGAffineTransformMakeRotation(degreesToRadian(90));
[picker.view setTransform:landscapeTransform];
You can make your own mailcomposer that is derived from MFMailComposeViewController and you can overwrite only the function shouldAutorotateToInterfaceorientation.
I didn't try this, just give you an idea.
Who is managing your EmailScene object? If you have followed the MVC pattern, try present the MFMailComposeViewController object using the viewController of EmailScene view. This will work provided you have supported all orientations in the view controller.
Use:
-(void)presentModalViewController:(UIViewController *)modalViewController animated:(BOOL)animated
Instead of adding the MFMailComposeViewController's view as a subview.
Edit: Try to present the MFMailComposeViewController using the root view controller.
I want to present a modal mail dialogue like so in the iPad app:
MFMailComposeViewController* picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
[picker setSubject:title];
[picker setMessageBody:[NSString stringWithFormat:[self emailBody], title, [link absoluteString]] isHTML:YES];
[self.viewController presentModalViewController:picker animated:YES];
The following delegate is called when the user sends/cancels:
- (void) mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
[self.viewController dismissModalViewControllerAnimated:YES];
}
This works great in portrait mode. In landscape mode the right hand pane of the UISplitViewController completely disappears.
You can only present these from the primary view of your application. In this case, presenting from the UISplitViewController works.
