I’m trying to use objc_msgSend_stret to call -bounds on a UIScreen. I have the following code:
> SEL bounds = NSSelectorFromString(@"bounds"); > CGRect screenBounds; > objc_msgSend_stret((void *)&screenBounds, screen, bounds); The declaration of objc_msgSend_stret in the Xcode code sense pop-up is as follows: > void objc_msgSend_stret(void * stretAddr, id self, SEL op, ...); But that’s not what message.h would leave me to believe (with some unrelated lines removed): > #if defined(__OBJC2__) > OBJC_EXPORT void objc_msgSend_stret(id self, SEL op, ...); > #else > /* For compatibility with old objc-runtime.h header */ > OBJC_EXPORT void objc_msgSend_stret(void * stretAddr, id self, SEL op, ...); > #endif So, if the declaration is actually the first (I’m compiling for iOS 4.2, so I’m pretty sure __OBJC2__ is defined), how do you use it and get the return value of the function?
