I have created SharePoint calendar list and added it to my custom page (with the custom master page).some time sp.ui.applicationpages.calendar.debug.js not loaded in IOS mobiles(also not loaded in system pages). how to load this files manually in the master page. suggest some idea to resolve this issue.
Could you try to include this in the masterpage where the script links are located.
<SharePoint:ScriptLink ID="SPCalendarDebug" name="sp.ui.applicationpages.calendar.debug.js" runat="server" ondemand="false" localizable="false" loadafterui="true" />
