Common Save Patterns

Standard background save

Assuming that you don't care which NSManagedObjectContext is used, and you just want to make some changes and save them in the background, use the following method. 90% of the time, this is what you'll want.

NSManagedObjectSubclass *myObject = [NSManagedObjectSubclass MR_findFirst];

[MagicalRecord saveWithBlock:^(NSManagedObjectContext *localContext) {

Generate the list yourself:

$ cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS*.sdk/System/Library/Frameworks/UIKit.framework/Headers
$ grep -H UI_APPEARANCE_SELECTOR ./* | sed 's/ __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_5_0) UI_APPEARANCE_SELECTOR;//'

Triggering a Cron Job manually on Kubernetes

So you've defined a cronjob.yaml manifest, but it doesn't run until midnight and you want to test it now? Simply replace the variables, and run the following command to create a job from the cronjob.

kubectl create job --from=cronjob/{{ cron_job_name }} {{ the-name-of-this-one-off-job }}

This will create a one-off job in your cluster based on your cronjob.yaml manifest, which might look something like this.

	// info.plist from Test 5
	// Open your info.plist and look for CFBundleURLSchemes
	// this is the string that you will use to open that app
	// You can also copy the info.plist to the root of your app and edit it.
	// You can even have multiple schemes that you can use to launch it.
	// Here I can launch the app using either 'test5://' or 'pedro://'
	// Be SURE to do a clean build
