Question

I upgraded my Xcode to Version 4.5.1 and suddenly previous app development had ‘potentially insecure’ during build.

it generally applies to declaring this type of construct:

NSString *userChoice = [NSString stringWithFormat:label1a.text]; //Warning at pulling string from label1a.text
[usrAnswer setObject:userChoice forKey:@"1"];

is this a serious warning? How do i rectify this?

Answer 1

You are not using a format string. Just do this:

NSString *userChoice = label1a.text;

I see a lot of people create strings with stringWithFormat:. Only use that when you are actually creating a string with format specifiers.
