How do I temporary disable warnings in my objective c source file?

Question

One project I work on has a build system that enforces no warnings.

But I have some code that needs warnings to work. Here is an example

NSString* title = @"";
if ([view respondsToSelector:@selector(title)]) {
  title = [view title];
}

After some googling I tried disable warnings for the code block by wrapping that code area with

#pragma warning disable
// my code
#pragma warning restore

Didn't work :(

Anyone know how to do this in Xcode?

Any help is appreciated.

Answer 1

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wshadow-ivar"
// your code
#pragma GCC diagnostic pop

You can learn about GCC pragma here and to get the warning code of a warning go to the Log Navigator (Command+7), select the topmost build, expand the log (the '=' button on the right), and scroll to the bottom and there your warning code is within square brackets like this [-Wshadow-ivar]

Edit

For clang you can use

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wshadow-ivar"
// your code
#pragma clang diagnostic pop
