NSArray First Element

Probably one of the most useful methods to have in a category on an NSArray is this method. It allows you easily and safely grab the first element of the array. This makes for a great counterpart to the already existing method -[someArray lastObject];

- (id)firstObject {

if (self.count > 0) {

return self[0];

}

return nil;

}
