问题 My Xcode started to behave very heavily from yesterday when working on medium size project (around 200 source files). Project compiles correctly and runs in both simulator and device. I do not use any 3rd party libraries, except few widely used includes (like JSON or facebook ios sdk). It constantly uses CPU(s) at full speed, even if it is in idle state (no indexing, no compiling, no editing). The usage of RAM is relatively normal (300-50MB). My machine uses: Core 2 Duo 3.04Ghz CPU, 8GB of

问题 Does anybody know why there are in XCode templates (at least in XCode 4.3.2) prefixed some ivars with two underscore and some with only one? For example the Master-Detail application template contains file MasterViewController.m, where one can find: @synthesize detailViewController = _detailViewController; @synthesize fetchedResultsController = __fetchedResultsController; @synthesize managedObjectContext = __managedObjectContext; Thanks. 回答1: It's a small can of worms.
