Which GLSL ES extensions are available on various iOS devices?

问题

I'm looking for a list of all extensions available on any iOS devices (and which are available on which device). I haven't found the right page in the apple docs despite a lot of searching, but I'm sure it's there somewhere. Any pointers?

回答1:

This code should print out all extensions:

NSString *extensionString = [NSString stringWithUTF8String:(char *)glGetString(GL_EXTENSIONS)];
NSArray *extensions = [extensionString componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
for (NSString *oneExtension in extensions)
    NSLog(@"%@", oneExtension);

Apple maintains a list of GPUs used in its devices and which extensions are supported on each in its iOS Device Compatibility Reference.
