Please can someone tell me how to have the test harness not instantiate the whole app? My app is event driven, and it sends a bunch of events through when it starts up that mess with my tests. I use Xcode 4’s built-in testing. App instantiation may seem like a pain, but as I write … Read more
You can perform your own crash-logging with PLCrashReporter. Typically, you write the crash log to a file and then send it to a server the next time the app starts. In order to prevent an infinite crash-reporting loop (there was one in an early version), you want to do things in a specific order: Read … Read more

Assuming that MyRecorder is a struct, this sets every member to their respective representation of zero (0 for integers, NULL for pointers etc.). Actually this also works on all other datatypes like int, double, pointers, arrays, nested structures, …, everything you can imagine (thanks to pmg for pointing this out!) UPDATE: A quote extracted from … Read more
NSZone is Apple’s way of optimizing object allocation and freeing. NSZone is not an object; it is an opaque C-struct storing information about how memory should be handled for a set of objects. One rarely needs to worry about handling your own zones in applications; Cocoa handles it transparently. A default NSZone is created on … Read more
Yes, you can use the following: #if __has_feature(objc_arc) … #endif Even if you’re using the latest version of LLVM, this will only evaluate to true if you’re compiling with the -fobjc-arc option.
