 Add the `DCIntrospect` class files to your project, add the QuartzCore framework if needed.  To start:
 
-    [window makeKeyAndDisplay]
-    
-    // always call after makeKeyAndDisplay.
-    #if TARGET_IPHONE_SIMULATOR
-        [[DCIntrospect sharedIntrospector] start];

+// always call after makeKeyAndDisplay.
+#if TARGET_IPHONE_SIMULATOR
+    [[DCIntrospect sharedIntrospector] start];
+#endif

 The `#if` to target the simulator is not required but is a good idea to further prevent leaving it on in production code.
