- Xcode 10 (already supported) - merged the framework targets into multi-platform ones - using xcconfig for most of the configurations (Lumberjack.xcodeproj + Tests.xcodeproj + Demos) - only adding setting in xcodeproj where they are not valid for all the other targets - set deployment target to iOS8 and Mac OS 10.10 - also cleaned up some branched code for the earlier versions - updated Travis scripts

Automatically use different log levels per xcode configuration.
|
|
|
|
# Xcode 4+
|
|
|
|
Starting with Xcode 4, the `DEBUG` preprocessor macro is automatically set when building for debug (as opposed to release). So you can use this to automatically get different log levels depending upon your current build configuration.
|
|
|
|
```objc
|
|
#ifdef DEBUG
|
|
static const DDLogLevel ddLogLevel = DDLogLevelVerbose;
|
|
#else
|
|
static const DDLogLevel ddLogLevel = DDLogLevelWarning;
|
|
#endif
|
|
```
|
|
|
|
Nothing else is needed. (No changes required of your xcode project.) If the DEBUG macro isn't set in your project, it likely means you originally created the project with Xcode 3 (or before the DEBUG macro became standard). In that case, read on.

# Xcode 3
|
|
|
|
Xcode has powerful configuration tools that we can tap into to automatically use different log levels depending on whether we're compiling in Debug vs Release mode.
|
|
|
|
When we're done we'll be able to have code like this:
|
|
|
|
```objc
|
|
#ifdef CONFIGURATION_DEBUG
|
|
static const DDLogLevel ddLogLevel = DDLogLevelVerbose;
|
|
#else
|
|
static const DDLogLevel ddLogLevel = DDLogLevelWarning;
|
|
#endif
|
|
```
|
|
|
|
### Details
|
|
|
|
Open your Xcode project and go to:
|
|
|
|
Project -\> Edit **Project** Settings
|
|
|
|
Now change the configuration to **Debug Configuration**.
|
|
|
|
Filter on "preprocessor" so you can find the **Preprocessor Macros Not Used In Precompilation** setting.
|
|
|
|
Now add a **CONFIGURATION\_DEBUG** value to this setting.
|
|
|
|
Your project settings should look like this:

|
|
|
|
Next, switch the configuration to **Release Configuration**.
|
|
|
|
Now add a **CONFIGURATION\_RELEASE** to the **Preprocessor Macros Not Used In Precompilation** setting.
|
|
|
|
Your project settings should look like this:
|
|
|
|
<a href="http://www.flickr.com/photos/100714763@N06/9575920131/" title="CocoaLumberjack_xcode2 by robbiehanson, on Flickr"><img src="http://farm4.staticflickr.com/3808/9575920131_52625d8f01_o.png" width="653" height="673" alt="CocoaLumberjack_xcode2"></a>
|
|
|
|
And that's all there is to it. You're done!
|
|
|
|
And this isn't limited to just logging.
|
|
You can use the `#ifdef CONFIGURATION_DEBUG` anywhere you want in your project if you feel the need to differentiate something between your debug and release builds.
