I’ve been racking my brain on how to select a specific iOS emulator device model to test my Ionic project in. Then I stumbled onto this very useful StackOverflow post, and I am just linking to it here as (a) a service for everyone else, and also (b) so I have a bookmark that I can revisit during my next testing session.
StackOverflow thread: http://stackoverflow.com/questions/22310526/cordova-start-specific-ios-emulator-image
Basically, to get a list of available device images on your system that you can test against, run:
$ ./platforms/ios/cordova/lib/list-emulator-images
On my system, this is the list I get:
iPhone-4s
iPhone-5
iPhone-5s
iPhone-6-Plus
iPhone-6
iPad-2
iPad-Retina
iPad-Air
Resizable-iPhone
Resizable-iPad
$
Now, if I wanted to test again, say the iPhone 6, I would type in:
$ ionic emulate ios --target="iPhone-6"
Similarly, if I wanted to test in an older iPad emulator, I would type in:
$ ionic emulate ios --target="iPad-2"
I find the emulators very useful for creating the screen shots to be uploaded to the app store. I run up my app on each device model and use [Command-S] to save the screen shots to a folder and then upload to the App Store and they are perfect dimensions.
Hope this helps others too.
