that is now available in cocos2d 0.99.5
I mentioned in a forum post about how cool it is not that we have an actual view controller available to us to hang stuff off of. A few people have asked about what I was referring to, so here's a sample project.
This is just the cocos2d base template with the MessageUI framework added (required for in-app email) and a few bits of code.
First we'll add a menu to "Hello World", add this in the layer init;
CCMenuItem *emailItem = [CCMenuItemFont itemFromString: @"Email" target:self selector:@selector(emailCallback)];
CCMenu *menu = [CCMenu menuWithItems: emailItem, nil];
menu.position = ccp(50,50);
[self addChild:menu];
Now add the emailCallback method;
-(void) emailCallback
{
[(BaseEmailAppDelegate*)[[UIApplication sharedApplication] delegate] sendEmail];
}
In our app delegate we need to create our sendEmail method;
In the .h file
-(void)sendEmail;
In the .m file
-(void)sendEmail
{
[viewController displayComposer];
}
In our RootViewController we need to create our displayComposer method;
In the .h file
Import the MessageUI header
#import <MessageUI/MessageUI.h>
and add MFMailComposeViewControllerDelegate
@interface RootViewController : UIViewController <MFMailComposeViewControllerDelegate>
{
}
-(void)displayComposer;
@end
In the .m file
@implementation RootViewController
#pragma mark -
#pragma mark Setup Mail Alert
- (void)setUpMailAccount {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"System Error"
message:@"Please setup a mail account first."
delegate:self
cancelButtonTitle:@"Dismiss"
otherButtonTitles:nil];
[alert show];
[alert release];
}
#pragma mark -
#pragma mark Compose Mail
// Displays an email composition interface inside the application. Populates all the Mail fields.
-(void)displayComposerSheet {
if(![MFMailComposeViewController canSendMail]) {
[self setUpMailAccount];
return;
}
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
[self presentModalViewController:picker animated:YES];
[picker release];
}
-(void)displayComposer {
NSLog(@"pop-up email here");
[self displayComposerSheet];
}
// Dismisses the email composition interface when users tap Cancel or Send. Proceeds to update the message field with the result of the operation.
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
// Notifies users about errors associated with the interface
switch (result)
{
case MFMailComposeResultCancelled:
break;
case MFMailComposeResultSaved:
break;
case MFMailComposeResultSent:
break;
case MFMailComposeResultFailed:
break;
default:
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Email" message:@"Sending Failed - Unknown Error :-("
delegate:self cancelButtonTitle:@"OK"
otherButtonTitles: nil];
[alert show];
[alert release];
}
break;
}
[self dismissModalViewControllerAnimated:YES];
}
Here is the
LINK to the sample project.
