Question

I have lunched the Static analyzer in my app and i have some warnings (errors) and i don’t know how to avoid theme, the warnings are :

Dead store ....

the code line is :

NSArray *listHighlights = [NSArray array];
 listHighlights = [jsonParser objectWithString:highlightText error:&error];
....

I think that i can do like this, but the object listHighlights is not allocate ??

NSArray *listHighlights = [jsonParser objectWithString:highlightText error:&error];

Answer 1

This…

NSArray *listHighlights = [NSArray array];

…makes your variable point to an autoreleased array, and you then immediately overwrite the address of that object with whatever is returned from objectWithString:…presumably another array that it has created. Because of the autorelease, it’s not actually a leak but it’s certainly a waste of effort.
