Orientation always in Portrait iOS6

Right had to do a bit of research for this one, here is the fix I found that works from Natalie London

In your APP DELEGATE.m

NSString *reqSysVer = @"6.0";
NSString *currSysVer = [[UIDevice currentDevice] systemVersion];

if ([currSysVer compare:reqSysVer options:NSNumericSearch] != NSOrderedAscending){
[window setRootViewController:viewController]; // This is for IOS6.....
}else{
[window addSubview: viewController.view]; //This is for < IOS6....... (the old way)
}

In your ROOTVIEWCONTROLLER.m //will only be compiled for IOS6

FOR LANDSCAPE USE THIS


- (NSUInteger) supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscape;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
return UIInterfaceOrientationLandscapeRight;
}

- (BOOL) shouldAutorotate {
return YES;
}

FOR PORTRAIT USE THIS


- (NSUInteger) supportedInterfaceOrientations {
return  UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
return UIInterfaceOrientationPortrait;
}

- (BOOL) shouldAutorotate {
return YES;
}

Project Code for Universal App Creation

Step 1

In your Target Info set the Targeted Device Family to “iPhone/iPad”

Step 2

In your appDelegate.m put this bit of code


- (BOOL) isIpad {
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 30200
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
return YES;

} else {
return NO;
}
#else
return NO;
#endif
}

To reference it in your other classes do this

in class.h


@interface YourLayerClass : CCLayer {

YourAppDelegate *theDelegate;
Boolean *isIpad;
}

in class.m in your init method


-(id) init
{
if( (self=[super init] )) {

//DEFINE iPad or iPhone
theDelegate = (YourAppDelegate*)[[UIApplication sharedApplication] delegate];
isIpad = [theDelegate isIpad];

}
}

And you can use it in your class thusly


if(isIpad == NO){
bg = [CCSprite spriteWithFile:@"xx_iphone.png"];
}else {
bg = [CCSprite spriteWithFile:@"xx_ipad.png"];
}

simple cocos2d animation using .png sequence

Right, so I do a lot of animation in my apps, so here is the most simple creation of it

yourfile.h

@private CCSprite *youranimref;
@private CCAnimation *animation;

yourfile.m

-(id) init
{
if( (self=[super init] )) {

self.isTouchEnabled = YES;

size = [[CCDirector sharedDirector] winSize];

// DECLARE ANIMATION
animation = [[CCAnimation alloc] initWithName:@"youranimref" delay:1/24.0];
youranimref = [CCSprite spriteWithFile:@"yourFirstAnimGrfx.png"];
[animation addFrameWithFilename: @"yourSecondAnimGrfx.png"];
[animation addFrameWithFilename: @"yourThirdAnimGrfx.png"];
[animation addFrameWithFilename: @"yourFourthAnimGrfx.png"];

// ADD ANIMATION
youranimref.position = ccp( 512, 435 );
[self addChild:youranimref z:5];

}
return self;
}

- (void) dealloc
{

// !!!!! VERY IMPORTANT - REMOVE TEXTURES AND RELEASE REFERENCE TO THE ANIMATION

[[CCTextureCache sharedTextureCache] removeUnusedTextures];
[[CCSpriteFrameCache sharedSpriteFrameCache] removeUnusedSpriteFrames];

// RELEASE RETAINED OBJECTS
[animation release];

[super dealloc];
}

- (void) runAnimation
{

// RUN THE ANIMATION

CCAnimate* action = [CCAnimate actionWithAnimation:animation];
[youranimref runAction:action];

}

Code for multitouch

In my latest app Loopy Tunes, I needed to add multitouch functionality to a keyboard. I use Cocos2D, so if you’re like me, then just do the following.

In your delegate.m class, add this line

[glView setMultipleTouchEnabled:YES];

right after this one.

[director setOpenGLView:glView];

Then in your class.m where you are testing for multitouch, up in your init method, add the following line

self.isTouchEnabled = YES;

And then add your touch method somewhere down under the init method, just update the values of the areaToCheck


- (void)ccTouchesBegan:(NSSet*)touches withEvent:(UIEvent*)event
{
NSSet *allTouches = [event allTouches];
for (UITouch* touch in allTouches) {

CGPoint location = [touch locationInView:[touch view]];
location = [[CCDirector sharedDirector] convertToGL:location];

CGRect areaToCheck = CGRectMake(100,100,100,100);
if(CGRectContainsPoint(areaToCheck, location)) {
// whatever you want to happen here
}
}
}

Icons required for a universal app

When preparing my universal app for iTunes I was having trouble with getting the icon.png file the right size. When I saved a 57×57 pixel icon iTunes complained about needing a 72×72 pixel icon for the iPad an vice versa for the iPhone. So I googled and found there are a couple of things you need to do.

STEP 1

Create all the icons listed in here under Table 3: Universal apps icon requirements. Then add them to your project in xcode. (you know, drag em into your resources folder)

http://developer.apple.com/library/ios/#qa/qa1686/_index.html

STEP 2

On that same page down the bottom are the instructions for how to enter these to your info.plist. Follow them, or just add this to your info.plist if it isn’t in there already.  (I prefer to edit the info.plist myself in textEdit) If you are using a cocos project, especially 0.99.5 or newer, it should already be in there.


Icon files

Icon.png
Icon@2x.png
Icon-72.png
Icon-Small-50.png
Icon-Small.png
Icon-Small@2x.png

STEP 3

If you have the following in your info.plist,


CFBundleIconFile

replace it with

CFBundleIconFiles

Icon.png
Icon-72.png

Code – link from your app to the app store

A good way to get people to review your app easily is to put a link to the review page in your app. Easy to do, just add this


[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://itunes.apple.com/us/app/a-fine-musician/id406573790?mt=8"]];

and replace “a-fine-musician” with your app name, and “406573790” with your app id.
