CFStringCreateByCombiningStrings(_:_:_:)

Creates a single string from the individual CFString objects that comprise the elements of an array.

Declaration

func CFStringCreateByCombiningStrings(_ alloc: CFAllocator!, _ theArray: CFArray!, _ separatorString: CFString!) -> CFString!

Parameters

  • alloc:

    The allocator to use to allocate memory for the new string. Pass NULL or Kcfallocatordefault to use the current default allocator.

  • theArray:

    An array of CFString objects to concatenate. This value should not be NULL.

  • separatorString:

    The string to insert between the substrings in the returned string. This value is commonly a whitespace character such as a tab or a newline (carriage return). If this value is not a valid CFString object, an assertion is raised.

Return Value

A string that contains a concatenation of the strings in theArray separated by separatorString. The order of the substrings in the string is identical to the order of the elements in theArray.

Discussion

If theArray is empty, returns an empty CFString object; if theArray contains one CFString object, that object is returned (without the separator string). Returns NULL if there was a problem in creating the string. Ownership follows the The Create Rule.
