# numberOfArguments

The number of arguments recorded in the receiver.

## Declaration

```occ
@property (readonly) NSUInteger numberOfArguments;
```

## Discussion

Discussion There are always at least two arguments, because an NSMethodSignature object includes the implicit arguments self and _cmd, which are the first two arguments passed to every method implementation.
