Probably Approximately Correct Location for iOS

If you’re writing an iOS app and you need to know the user’s current location, the answer is straightforward: use Core Location. That fires up device GPS (when available). Apple’s A-GPS combines this with things like local Wifi networks and IP addresses to work out the device’s location. All of this, of course, assuming that […]

Mark Dalrymple on the Objective-C Run Time

Over at the Big Nerd Ranch blog, my friend Mark Dalrymple continues his “Inside the Bracket” series with an article on practical uses of Objective-C’s run time introspection. Last time you saw the parts of the Objective-C runtime API that let you query a bunch of the metadata the compiler keeps around once it’s done […]

Dropbox Datastore, the iCloud Killer? (updated)

iCloud Complications, Part 3: I’m Waiting…

In today’s installment of my continuing series on using iCloud with Core Data I’m going to discuss how factors beyond your control may render iCloud unusable, even if everything is working normally. Even if everything is working correctly, the current API can still require complex workarounds to get decent app performance. Through this, keep in […]

Introducing momcom

From the README on github: momcom is a command-line tool for Mac OS X that takes an uncompiled Core Data model created with Xcode and compiles it to produce a compiled .mom or .momd suitable for use at run time. Please note that momcom is experimental. Although it is intended to be at least as […]

Introducing momdec

From the README on github: momdec is a command-line tool for Mac OS X that takes a compiled Core Data model and decompiles it to produce an equivalent xcdatamodel or xcdatamodeld suitable for use in Xcode. The resulting model file can also be used with mogenerator to produce source code files for Core Data entities […]
