Returns a range from a textual representation.
SWIFT
Returns a range from a textual representation.
Declaration
SWIFT
func NSRangeFromString(_ aString : String) -> NSRange
OBJECTIVE-C NSRange NSRangeFromString ( NSString *aString );
Discussion
Scans aString for two integers which are used as the location and length values, in that order, to create an NSRange struct. If aString only contains a single integer, it is used as the location value. If aString does not contain any integers, this function returns an NSRange struct whose location and length values are both 0.
Availability
Available in iOS 2.0 and later.
