Custom url's for ios devices

[yasmanets]

With these changes you can set custom urls for iOS devices.
Initializing the properties vCard.iosURL and vCard.label as an empty array and putting in each position of the array a url and its label respectively. As in the following example:

vCard.iosURL = [ ];
vCard.label = [ ];

testCard.iosURL.push('https://www.treeala.com');
testCard.iosURL.push('https://www.twitter.com/yasmaniaco');
testCard.iosURL.push('https://www.instagram.com/yasmanets');
testCard.iosURL.push('https://github.com/yasmanets');

testCard.label.push('Web page');
testCard.label.push('Twitter');
testCard.label.push('Instagram');
testCard.label.push('Github');`

You will get the following result:
