Turn Deprecation Warnings Back On - objective-c

Question

After creating a new target in an iOS project, there are tons of deprecation warnings. I want to see these in the other targets, too.
I've searched my whole project for deprecated (as this answer would indicate) and I've also looked for -W (as mentioned here), and found that I did do this:
#pragma clang diagnostic ignored "-Warc-performSelector-leaks"
in one or two places, but that's not it. I've looked at most answers regarding suppressing warnings, but I haven't found where I shut this off.
Where else might deprecation warnings been shut off? I would like to turn my warnings back on.
Example
This should result in a warning:
self.numericLabel.lineBreakMode = UILineBreakModeClip;// NSLineBreakByClipping;

Answer 1

Because comments are folded up by default and sometimes get missed, I am elaborating on Greg's comment with an example.
Deprecation warnings are only printed if your Deployment Target is newer than the first deprecation of the API.
Example 1:
Using: [TWTweetComposeViewController canSendTweet]
Deprecation in Apple's document:NS_DEPRECATED(NA, NA, 5_0, 6_0)
Deployment Target: iOS 5.0
iOS SDK: 6.1
Warning: No
Example 2:
Using: [TWTweetComposeViewController canSendTweet]
Deprecation in Apple's document:NS_DEPRECATED(NA, NA, 5_0, 6_0)
Deployment Target: iOS 6.1
iOS SDK: 6.1
Warning: Yes
In Example1, the apple's deprecation document states that the api was introduced in iOS 5.0 and deprecated in iOS 6.0. So although my iOS SDK(xcode) was 6.1, I was not getting any warning since my deployment target was iOS 5.0 which would need that api.
In Example2, I changed my deployment target to iOS 6.1 and the warning started appearing.
Conclusion: Deployment target is generally the lowest iOS version that you want your app to support. If you set that to a version that's subsequent to the deprecation of an API, the warnings start showing up in Xcode
