Ionic - app hangs on splash screen

问题

My ionic app is hanging on the splash screen - it was working fine and then I added some code, and went to test, and it's getting stuck.

It gets to this point:

The deviceready message never comes.

One thing I did that is kind of relevant is, when I was building or something ionic asked me to upgrade ios-deploy from 1.9.1 to 1.9.2. I think this started happening after I did that. I try to revert back to 1.9.1 but it won't let me:

ld: framework not found MobileDevice
clang: error: linker command failed with exit code 1 (use -v to see invocation)

That might not be the problem. I could really use some help I'm close to a deadline.

UPDATE

When I try to run in xcode the same thing happens, but xcode gives these errors:

2017-10-10 15:49:17.417901-0400 myApp[8476:3520766] Resetting plugins due to page load.
2017-10-10 15:49:38.433127-0400 myApp[8476:3520766] Failed to load webpage with error: The request timed out.

UPDATE

I figured out what was causing this - it's livereload - if I run it without that its fine...but I kind of need it to work to develop.

回答1:

I didn't have my wifi enabled on my phone so it couldn't connect to ionic.

回答2:

From my experience we have the same issue deviceready is never shown in our console log, the most possible case would be inconsistency of the Cordova Plugin one thing that you could do is to reinstall the plugins and try to delete your platform folder and make a clean build with npm cache clean .

Update:

Based on your update , how are you running your ios app ?

Are you running your app using the -l -c commands like below:

ionic run ios -l -c

if that is the case you may be noticed that this command changes a line in the config.xml file:

// from <content src="index.html"/>

// to <content src="localhost//192.1.168.0:8000" original-src="index.html"/>

So Changing it back to <content src="index.html"/> might fixes the issue.

Solution 2:

You probably need to whitelist the localhost in the following way:

<allow-navigation href="http://localhost:8100/*"/>

回答3:

My best guess is that your iPhone did not yet prepare the debugger for iOS11. It does so when running your app the first time on an new iOS version. You have to open and run your project once using XCode then you should be fine. Please also make sure you have the most recent version of cordova-ios which is 4.5.1 (check the <engine name=ios"> tag in your config.xml).
