Man this cancel button does nothing at all other than dismissing action sheet. If you want to get rid of mail composer you have to press cancel at upper left corner which shows you an action sheet at the bottom with options Delete Draft, Save Draft and cancel. Delete draft and save draft will dismiss the mail composer and the delegate function will be called. Cancel button will actually dismiss action sheet in order to save the mail composer from dismissing in case if user accidentally clicked that cancel button at the top
I am trying to allow the player to share their score by SMS when the game is over.
I have imported the framework in to my project. Imported in the my viewController.h file.
here is my viewController.h file
#import <UIKit/UIKit.h>
#import <SpriteKit/SpriteKit.h>
#import <MessageUI/MessageUI.h>
#interface myViewController : UIViewController <MFMessageComposeViewControllerDelegate> {
}
#end
I also tried to import into MyScene.h like so:
#import <MessageUI/MessageUI.h>
#interface MyScene : SKScene <MFMessageComposeViewControllerDelegate> {
}
When I want to show the SMS share, I use this code in my MyScene.m file
MFMessageComposeViewController *textComposer = [[MFMessageComposeViewController alloc] init];
[textComposer setMessageComposeDelegate:self];
if ([MFMessageComposeViewController canSendText]) {
[textComposer setRecipients:[NSArray arrayWithObject:nil]];
[textComposer setBody:#"Happy Happy Joy Joy!"];
[self presentViewController:textComposer animated:YES completion:NULL];
} else {
NSLog(#"Cant send text!");
}
But on this line
[self presentViewController:textComposer animated:YES completion:NULL];
I get an "No visible #interface for 'MyScene' declares the selector 'presentViewController:animated:completion:'" error.
I have tried to search for the last couple hours. Try god knows how many variations and examples from other posts/tutorials(which was good to learn a few things unrelated to this). Nothing seems the work. I starting to run out of hair to pull out. So any help would be great. I am sure for some of you Gurus here this should be a walk in the park. Thanks.
EDIT: I am not using storyboard, or the view controller for buttons/menu/game play etc...hence why I am not able to call the function from within the viewController itself.
EDIT:
So I tried what Paulw11 suggested in his link. Now I have the following errors.
in myViewController
MyScene.MyViewController = self;
I get a "Property 'MyViewController' not found on object of type 'MyScene'" error
also in MyScene.m
- (void)sendToController
{
NSLog(#"ok");
// use the already-created spriteViewController
[_MyViewController sendSMS];
}
[_MyViewController sendSMS]; line I get an "No visible #interface for 'MyViewController' declares the selector 'SendSMS'"
EDIT 2: *EDIT 2:* EDIT 2: *EDIT 2:*
I got it to open up the SMS. Small problem, it does not allow me to dismiss it /cancel.
Here is my sendSMS code:
-(void) sendSMS {
MFMessageComposeViewController *textComposer = [[MFMessageComposeViewController alloc] init];
[textComposer setMessageComposeDelegate:self];
if ([MFMessageComposeViewController canSendText]) {
[textComposer setRecipients:[NSArray arrayWithObject:#" "]];
NSString *body = [NSString stringWithFormat:#"Happy Day!: %i. ", _score];
[textComposer setBody:body];
UIViewController *vc = self.view.window.rootViewController;
[vc presentViewController: textComposer animated: YES completion:nil];
} else {
NSLog(#"Cant send text!");
}
}
Here is my dismiss code:
-(void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result {
UIViewController *vc = self.view.window.rootViewController;
[vc dismissViewControllerAnimated:YES completion:NULL];
}
EDIT 3
The following code gives me the NSLog at the correct times, but does not dismiss the window.
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller
didFinishWithResult:(MessageComposeResult)result
{
UIViewController *vc = self.view.window.rootViewController;
// Notifies users about errors associated with the interface
switch (result)
{
case MessageComposeResultCancelled:
NSLog(#"Result: SMS sending canceled");
break;
case MessageComposeResultSent:
NSLog(#"Result: SMS sent");
break;
case MessageComposeResultFailed:
NSLog(#"Result: SMS sending failed");
break;
default:
NSLog(#"Result: SMS not sent");
break;
}
[vc dismissViewControllerAnimated:YES completion:NULL];
}
If you refer to the MFMessageComposeViewController Class Reference you will see that you need to present it modally using presentModalViewController:animated:. You are also responsible for dismissing it via your delegate object once you are done.
I suggest you have a look at the Message Composer sample code for an example of using the MFMessageComposeViewController class.
UPDATE
You can just dismiss the view controller that was passed to your delegate method -
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller
didFinishWithResult:(MessageComposeResult)result
{
// Notifies users about errors associated with the interface
switch (result)
{
case MessageComposeResultCancelled:
NSLog(#"Result: SMS sending canceled");
break;
case MessageComposeResultSent:
NSLog(#"Result: SMS sent");
break;
case MessageComposeResultFailed:
NSLog(#"Result: SMS sending failed");
break;
default:
NSLog(#"Result: SMS not sent");
break;
}
[controller dismissViewControllerAnimated:YES completion:NULL];
}
For my iPhone app I want to implement the option to upload files to Soundcloud by making use of the CocoaSoundCloudAPI. In the instructions "How to use the SoundCloud API directly" it is explained how to modally present a loginViewController:
- (void)login {
[SCSoundCloud requestAccessWithPreparedAuthorizationURLHandler:
^(NSURL *preparedURL){
SCLoginViewController *loginViewController;
loginViewController =
[SCLoginViewController loginViewControllerWithPreparedURL:preparedURL
completionHandler:^(NSError *error){
if (SC_CANCELED(error)) {
NSLog(#"Canceled!");
} else if (error) {
NSLog(#"Ooops, something went wrong: %#", [error localizedDescription]);
} else {
NSLog(#"Done!");
}
}];
[self presentModalViewController:loginViewController
animated:YES];
}];
}
Now I replaced
[self presentModalViewController:loginViewController
animated:YES];
with
[self presentViewController:loginViewController
animated:YES
completion:nil];
because the first method is deprecated in iOS 7.
But the problem is that the Soundcloud loginViewController overlaps the status bar when presented in this fashion. And since I don't want to change the Soundcloud API I do not have the option to customize the loginViewController accordingly e.g. in its - viewDidLoad method (as suggested in many other posts on Stackoverflow).
Unfortunately there is a toolbar with a button on top the loginViewController. How can I configure my loginViewController from inside my own (presenting) view controller so that it won't overlap with the status bar when presented?
As mentioned in my comment to the original question I did not find a neat solution for this problem. However I managed to implement a workaround that does the job:
The basic idea is to add the SCLoginViewController as a child view controller of another custom view controller that is not part of the Soundcloud framework and that you can customize to your needs. This is my new login method that presents the login view controller:
- (BOOL)loginToSoundcloud {
BOOL __block success = NO;
[SCSoundCloud requestAccessWithPreparedAuthorizationURLHandler:^(NSURL *preparedURL){
SCLoginViewController *loginViewController;
loginViewController =
[SCLoginViewController loginViewControllerWithPreparedURL:preparedURL
completionHandler:^(NSError *error){
if (SC_CANCELED(error)) {
NSLog(#"Canceled!");
} else if (error) {
NSLog(#"Ooops, something went wrong: %#", [error localizedDescription]);
} else {
NSLog(#"Done!");
success = YES;
}
}];
/* BEGIN workaround for iOS7 bug:
when modally presenting a view controller it overlaps the status bar */
CBContainerVCToFixStatusBarOverlap *containerVC = [[CBContainerVCToFixStatusBarOverlap alloc] init];
[containerVC addChildViewController:loginViewController];
containerVC.view.backgroundColor = [UIColor clearColor];
if ([CBAppDelegate iOSVersionIs7OrHigher]) {
loginViewController.view.frame =
CGRectMake(loginViewController.view.frame.origin.x,
loginViewController.view.frame.origin.y + 20,
containerVC.view.frame.size.width,
containerVC.view.frame.size.height - 20);
} else {
loginViewController.view.frame =
CGRectMake(loginViewController.view.frame.origin.x,
loginViewController.view.frame.origin.y,
containerVC.view.frame.size.width,
containerVC.view.frame.size.height);
}
[containerVC.view addSubview:loginViewController.view];
/* END workaround for iOS7 bug */
[self presentViewController:containerVC
animated:YES
completion:nil];
}];
return success;
}
To check for the iOS version I implemented the following method in my CBAppDelegate:
+ (BOOL)iOSVersionIs7OrHigher {
return floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1;
}
CBContainerVCToFixStatusBarOverlap is a simple view controller class with no additional methods and only one declared property. This is the content of CBContainerVCToFixStatusBarOverlap.h:
#interface CBContainerVCToFixStatusBarOverlap : UIViewController
#property (strong, nonatomic) IBOutlet UIView *containerView;
#end
I am using Google AdMobs DFP to serve up mediation banners from other networks. I have added Millennial and InMobi fine but now I need to add a network (YOC group) that does not have an adapter for DFP so I need to implement 'custom event banners'. I have read the guides and technical documents on implementing unsupported mediator networks with custom events but still cannot understand how it hooks up the two SDKs (Google AdMobs SDK and the mediator network's SDK).
The network that doesn't have an adapter (YOC) works if I hard-code the yoc ad id (of the format '9A9A9AA99999999A999AA9A99AA99AAAA999A9AA') to a sample ad and send off the request. The banner comes back fine and uses the YOC SDK to show an interactive/rich media advert.
However in my app I only have a Google DFP account id (of the format '/9999/company.app/channel') which I send off a request for using Google AdMobs SDK to DFP. The request then returns a response with the specific mediator ad network to try and request a banner advert from. My current setup is that YOC serves 100% of ads in DFP.
Problem: I get a banner advert returned from the YOC ad network and it displays on screen. It registers page impressions (with DFP) but there is no response to a touch/press event the way it works as if I hard-code the initialisation parameters of the yoc ad view. I can't however hard-code the yoc ad id (when initialising) because it would only work for one banner advert and I need different banners for each specific advert in each channel.
Below is the sample code I am trying to implement using just NSLogs in the methods to log to the console and show that the methods are being called. It is a very basic app and puts all the code in one place for ease of reading.

Please can someone help give me things to try out and find out how to get the advert banner view returned from Google DFP responding to click events!?
There is a guide here on how to develop custom events.
If you're using AdMob SDK Mediation with ad unit /9999/company.app/channel, then this ad unit should be an SDK Mediation creative within DFP. One of your networks should be a Custom Event with the following settings:
Parameter: 9A9A9AA99999999A999AA9A99AA99AAAA999A9AA (or whatever your YOC tag is)
Label: YOC Group (This is just a label so you remember what this custom event is for)
Class Name: AppDelegate (You should really implement the custom event in it's own
class, and replace the class name with that class)
Then when implementing the custom event, you can reference serverParameter as the YOCTag like you already have.
You don't want to implement GADCustomEventBannerDelegate yourself. By your class implementing GADCustomEventBanner, and adding:
#synthesize delegate
at the top of your implementation, you have access to an instance of this object via:
self.delegate
You'll want to use that delegate to tell the custom event (and thereby AdMob Mediation) that YOC returned or failed to return an ad. Based on the YOC delegate, your mapping might look something like this:
- (UIViewController *)viewControllerForPresentingYOCAdView {
NSLog(#" viewControllerForPresentingYOCAdView ");
return self.root;
}
- (void)yocAdViewDidInitialize:(YOCAdView *)yocAdView {
NSLog(#" yocAdViewDidInitialize ");
// Assuming this means the yocAdView was received.
[self.delegate customEventBanner:self didReceiveAd:yocAdView];
}
- (void)yocAdView:(YOCAdView *)yocAdView didFailWithError:(NSError *)error {
NSLog(#" didFailWithError: %# ", error);
[self.delegate customEventBanner:self didFailAd:error];
}
- (void)yocAdViewDidHide:(YOCAdView *)yocAdView {
NSLog(#" yocAdViewDidHide ");
}
- (void)yocAdViewDidReload:(YOCAdView *)yocAdView {
NSLog(#" yocAdViewDidReload ");
[self.delegate customEventBanner:self didReceiveAd:yocAdView];
}
- (void)yocAdViewWillPresentModalViewController:(YOCAdView *)yocAdView {
NSLog(#" yocAdViewWillPresentModalViewController ");
[self.delegate customEventBanner:self clickDidOccurInAd:yocAdView];
[self.delegate customEventBannerWillPresentModal:self];
[self.delegate customEventBannerWillLeaveApplication:self];
}
- (void)yocAdViewWillDismissModalViewController:(YOCAdView *)yocAdView {
NSLog(#" yocAdViewWillDismissModalViewController ");
[self.delegate customEventBannerWillDismissModal:self];
}
Finally, you don't want to invoke GADCustomEventBannerDelegate methods in your GADBannerViewDelegate callback methods. These are invoked by AdMob telling you that mediation came back with an ad. The GADBannerViewDelegate implementation is part of your main app, and should stay out of your custom event class's implementation.
I know the guide invokes the custom event delegate methods in its GADBannerViewDelegate implementation. The difference is the guide is writing a custom event to implement AdMob, so in the context of the guide, the GADBannerViewDelegate is behaving like the YOCAdViewDelegate in your example.
I have a problem with the integration of game center in my app' which use iOS 6 SDK.
In fact I use the sample code from Apple, but it looks like incomplete :
I have tried this code :
-(void) authenticateLocalPlayer {
GKLocalPlayer* localPlayer =
[GKLocalPlayer localPlayer];
localPlayer.authenticateHandler =
^(UIViewController *loginVC,
NSError *error) {
[self setLastError:error];
if ([GKLocalPlayer localPlayer].authenticated)
{
// authentication successful
[self enableGameCenterForPlayer:[GKLocalPlayer localPlayer]];
}
else if (loginVC)
{
// player not logged in yet, present the vc
[self pauseGame];
[self presentLoginVC:loginVC];
}
else
{
// authentication failed, provide graceful fallback
[self disableGameCenter];
}
};
}
But the problem is that enableGameCenterForPlayer, pauseGame, presentLoginVC, disableGameCenter are not implemented methods, and it returns :
Instance method '-enableGameCenterForPlayer:' not found (return type defaults to 'id')
How can I fix this problem ?
Thanks
I use the method [self presentLoginVC:VC] to pass my UITabViewController or UINavigationController the viewController because the block below is not on the main thread.
localPlayer.authenticateHandler = ^(UIViewController *loginVC, NSError *error) {
When you are in a block you should be sure not to change UI elements because you really don't know when it will complete or where you will be in your app. There are probably many ways to do this, but this is my solution.
Below is my UITabBarController 'category' .m file (additions of methods for a class without subclassing) I create the method presentLoginVC and just have it call 'showGameCenterViewController' through my UITabBarController:
#import "UITabBarController+GameKitAdditions.h"
#implementation UITabBarController (GameKitAdditions)
-(void) showGameCenterViewController: (UIViewController *)VC {
[self presentViewController:VC animated:NO completion:nil];
}
-(void)dismissGameCenterViewController:(UIViewController *)VC {
[self dismissViewControllerAnimated:YES completion:nil];
}
#end
As to the other functions:
-(void) enableGameCenterForPlayer:(GKLocalPlayer *) localPlayer;
-(void) disableGameCenter;
-(void) pauseGame;
They could be as simple as just setting a BOOL called enableGameCenter to YES or NO. To get around errors you can just add these prototypes to your .h file and then write the functions just to output something to NSLog() or something.
