range(of:)
Finds and returns the range of the first occurrence of a given string within the string.
Declaration
func range(of searchString: String) -> NSRangeParameters
- searchString:
The string to search for.
Return Value
An NSRange structure giving the location and length in the receiver of the first occurrence of searchString. Returns {``NSNotFound``, 0} if searchString is not found or is empty ("").
Discussion
Invokes range(of:options:) with no options.
NSString objects are compared by checking the Unicode canonical equivalence of their code point sequences. The length of the returned range and that of searchString may differ if equivalent composed character sequences are matched.
