Instance Method

scanInteger:

Scans for an NSInteger value from a decimal representation, returning a found value by reference

Declaration

- (BOOL)scanInteger:(NSInteger *)result;

Parameters

value

Upon return, contains the scanned value. Contains INT_MAX or INT_MIN on overflow.

Return Value

YES if the receiver finds a valid integer representation, otherwise NO. Overflow is considered a valid integer representation.

Discussion

Skips past excess digits in the case of overflow, so the receiver’s position is past the entire integer representation.

Invoke this method with NULL as value to simply scan past a decimal integer representation.
