Yosemite中的Xcode 6 iOS SDK 8.0给出了OpenGL ES2代码的错误,它在Xcode 5下编译得很好

GLuint depthStencilRenderbuffer;
glBindRenderbufferOES(GL_RENDERBUFFER_OES, depthStencilRenderbuffer);
glRenderbufferStorageOES(GL_RENDERBUFFER_OES,
                         GL_DEPTH24_STENCIL8_OES,
                         self.view.bounds.size.width,
                         self.view.bounds.size.height);

生成错误:

第2行:

"glBindRenderBufferOES"的冲突类型

使用未声明的标识符'GL_RENDERBUFFER_OES'

第3行:

包含'glBindRenderBufferOES'的隐式声明在C99中无效

编辑:好的,我可以通过替换来重新开始工作:

GLuint depthStencilRenderbuffer;
glBindRenderbuffer(GL_RENDERBUFFER, depthStencilRenderbuffer);
glRenderbufferStorage(GL_RENDERBUFFER,
                      GL_STENCIL_INDEX8,
                      self.view.bounds.size.width,
                      self.view.bounds.size.height);

仍然 - 我不知道为什么需要这种改变,我很欣赏一些关于这里发生了什么的进一步见解.

在iOS8上,我正在使用UIActivityViewController与Facebook/Twitter等共享UIImage.它似乎工作正常,但今天它在我的iPad上运行代码时突然崩溃了.但是,它仍然可以在模拟器中按预期工作.

我的代码:

UIActivityViewController *controller =
[[UIActivityViewController alloc]
 initWithActivityItems:@[text, url, myImage]
 applicationActivities:nil];

[self presentViewController:controller animated:YES completion:nil];

崩溃后,Xcode吐出:
