Removing NSLogs for distributionGuides | Tutorial By b2cloud 5 years ago
When developing an iOS or Mac app, NSLogs are very handy during development. These are quite useless for an app on an end users phone or computer, so removing every log is often a good idea, especially if you like to log a lot of information. This might sound like a pain, commenting out every NSLog whenever you build for the AppStore? But no, there’s a much simpler solution, coming from our friend the preprocessor macro.
Using ScriptingBridgeGuides | Tutorial By b2cloud 5 years ago
When interacting with other applications on the Mac, AppleScript is the main option to use. Writing AppleScript to run within an application can be pretty annoying, and there’s no syntax checking unless you write it in AppleScript Editor first and then bring over the code.

Of course your target application must support Applescript, just as if you were writing the script manually.

As of June 1st this year all newly submitted apps and versions on the Mac Appstore require sandboxing. Sandboxing means that each app is run inside it’s own quarantined space to make sure the app doesn’t do anything malicious. For a lot of apps this will be sufficient, but for apps that let you do really special stuff this is the thing that kills them.
Disabling document locks in OS X LionGuides By b2cloud 5 years ago
In OS X Lion Apple introduced the concept of document versions, the ability to go back in time on documents and view or restore a version from the past.
