CTGetCoreTextVersion()

Declaration

func CTGetCoreTextVersion() -> UInt32

Return Value

The version number. This value is for comparison with the constants listed in Core Text Framework Version Numbers.

Discussion

This function returns a number indicating the version of the Core Text framework. Note that framework version is not always an accurate indicator of feature availability. The recommended way to use this function is first to check that the function pointer is non-null, followed by calling it and comparing its result to a defined constant (or constants). For example, to determine whether the CoreText API is available:

if (&CTGetCoreTextVersion != NULL && CTGetCoreTextVersion() >= kCTVersionNumber10_5) {
 // CoreText API is available
}
