This warning is popping up a bunch in some third party libraries.
Is there a way to handle it without modifying the code (e.g. ignore the warning)?
If I have to modify the code to fix it how do I do it?
Here's one of the code blocks that's causing a warning:
BOOL FBIsDeviceIPad() { #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 30200 if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { return YES; } #endif return NO; }
Usually with warnings like this you can just define a function prototype at the top of your file, for instance:
BOOL FBIsDeviceIPad();
But in C a method with nothing between the braces, i.e. ()
actually implies there are an arbitrary number of parameters. Instead the definition should become (void)
to denote no parameters:
BOOL FBIsDeviceIPad(void); ... BOOL FBIsDeviceIPad(void) { #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 30200 if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { return YES; } #endif return NO; }
