Scans for an unsigned value from a hexadecimal representation, returning a found value by reference.
Mac Catalyst 13.0+
Upon return, contains the scanned value. Contains UINT_MAX on overflow.
Returns YES if the receiver finds a valid hexadecimal integer representation, otherwise NO. Overflow is considered a valid hexadecimal integer representation.
The hexadecimal integer representation may optionally be preceded by 0x or 0X. Skips past excess digits in the case of overflow, so the receiver’s position is past the entire hexadecimal representation.
Invoke this method with NULL as intValue to simply scan past a hexadecimal integer representation.
