Ios6 support for cocos2d-iphone 2.x screen orientation

========================================================== =============================== Original blog, reprinted please declare the source of Electronic coffee (original id blue rock) ========================================================== ================================

In cocos2d1. X, we set the direction of ctor:

[[Director sharedDirector] setDeviceOrientation (ccDeviceOrientation)orientation];

In cocos2d 2.x, setdeviceorientation is no longer in use. Instead, use the following method:

* In didfinishlaunchingwitexceptions of appdelegate, set delegate to self and override the following method:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{   //do something you need   [director setDelegate:self];}//support device orientation- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{    return UIInterfaceOrientationIsLandscape(interfaceOrientation);}

Shouldautorotatetointerfaceorientation is not used in ios6 and later versions, but is replaced by the following two methods:

// Determine whether the UI will rotate with the device. Execute-(bool) shouldautorotate {return no;} before supportedinterfaceorientations. // set the device direction supported by the UI, which must be info. plist's target settings are the same. // execute-(nsuinteger) supportedinterfaceorientations {// return values; return uiinterfaceorientationmaskall;} Only when shouldautorotate returns yes ;}

Therefore, we need to make corresponding modifications,
1. Add the ccdirectordelegate method to ccprotocols. h:

@ Protocol ccdirectordelegate <nsobject> @ optional/** called by ccdirector when the porjection is updated, and "Custom" projection is used */-(void) updateprojection; # ifdef _ cc_platform_ios/** returns a Boolean value indicating whether the ccdirector suppsupports the specified orientation. default value is yes (supports all possible orientations) */-(bool) shouldautorotatetointerfaceorientation :( uiinterfaceorientation) interfaceorientation;/** for iOS 6 + Add two methods here */-(bool) shouldautorotate;-(nsuinteger) supportedinterfaceorientations;

2. Override the above two methods in ccdirectorios. M:

-(BOOL)shouldAutorotate{    BOOL ret =YES;if( [delegate_ respondsToSelector:_cmd] )ret = (BOOL) [delegate_ shouldAutorotate];    return ret;}-(NSUInteger)supportedInterfaceOrientations{    int ret =UIInterfaceOrientationMaskAll;if( [delegate_ respondsToSelector:_cmd] )ret = (int) [delegate_ supportedInterfaceOrientations];    return ret;}

3. Finally, rewrite in appdelegate:

//support ios 6+-(BOOL)shouldAutorotate{    NSLog(@"AppDelegate--------shouldAutorotate");    return NO;}- (NSUInteger)supportedInterfaceOrientations {    NSLog(@"AppDelegate--------supportedInterfaceOrientations");    return UIInterfaceOrientationMaskLandscapeLeft;}

4. The appdelegate rootview will be modified.

[window_ setRootViewController:navController_];

OK. modification is complete.
