Cordova-sqlite-storage: -[__NSDictionaryM length]: unrecognized selector

[prevostc]

I recently updated to 10.10.3 and xcode 6.3.1 and I can't use this plugin anymore. The app freezes after ~0.5s and disabling the plugin seems to solve the issue. I don't know ObjectiveC but I'll be happy to help you solve this problem.

Here is the stack trace I got from ionic run:

Looks like the same cause as was reported in litehelpers/Cordova-sqlcipher-adapter#5.

The example in the document at http://ngcordova.com/docs/plugins/sqlite/ tells you pass an object in the first argument, but looking in the code at https://github.com/driftyco/ng-cordova/blob/master/src/plugins/sqlite.js it really expects a string with the name of your database file.

I was able to reproduce your error with the following code in my sample app:

    var a1 = { name: 'aaa', location: 1};
    window.sqlitePlugin.openDatabase({name: a1}, function(db) { alert('ok')}, function(err) {alert('error')});

Please double-check your code and try it again.

I will add a check that the database name must be a string.

That solved the issue, thanks a lot! I was using ngCordova the wrong way.

$cordovaSQLite.openDB({ name: SQL_DB_NAME + '.db' }); // NOPE
$cordovaSQLite.openDB(SQL_DB_NAME + '.db') // YUP

FYI I just updated the Javascript to make sure the database name is given as a string, and throw an exception if not. Will add a test when I get a chance.

Thank prevostc you solution worked

FYI I just updated the Javascript to make sure the database name is given as a string, and throw an exception if not. Will add a test when I get a chance.

Test is now added, closing.
