Infer reports these warnings in Objective-C when a boxed primitive type such as
|
||
|
|
`NSNumber *` is coerced to a boolean in a comparison. For example, consider the
|
||
|
|
code
|
||
|
|
|
||
|
|
```objectivec
|
||
|
|
void foo(NSNumber * n) {
|
||
|
|
if (n) ...
|
||
|
|
```
|
||
|
|
|
||
|
|
The branch in the above code will be taken when the pointer `n` is non-`nil`,
|
||
|
|
but the programmer might have actually wanted the branch to be taken when the
|
||
|
|
integer pointed to by `n` is nonzero (e.g., she may have meant to call an
|
||
|
|
accessor like `[n intValue]` instead). Infer will ask the programmer explicitly
|
||
|
|
compare `n` to `nil` or call an accessor to clarify her intention.
