iphone - How to replace OpenGL ES 1.1 EAGLLayer view with OpenGL view from GLKit? -


i have simple game uses eagllayer directly. had set runloop , opengl es boilerplate. game crashes because of opengl backgrounding problems. heard glkit has robust boilerplate opengl view takes care of opengl initialize , suspension.

is possible set glkit view opengl 1.1 , start?

this rather open-ended question, it's best start getting background glkit , ask more questions if have specific issues.

take @ code when creating new xcode project using "opengl game" template -- sets glkview , glkviewcontroller you. there's description of how these classes work , how use them in apple's opengl es programming guide.

the overall gist of it: glkview of framebuffer, renderbuffer, , viewport setup , presentation basic opengl es drawing (including framebuffer juggling multisampling if want that) have issue drawing commands. glkviewcontroller owns glkview , runs animation timer calls drawing code -- default, makes sure not call drawing code when app in background.

if you're using glkviewcontroller , making opengl es calls glkview (subclass or delegate) drawing method, shouldn't have worry crashing due gpu use in background. if seeing such crashes (with gpus_returnnotpermittedkillclient in stack trace), can try forcing gl complete processing before going background -- call glfinish() in applicationwillresignactive:.

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
