I have seen a blog which claims that we can develop iPhone applications in HTML5. Untill then I was aware about Objective-C on Mac.
Can we develop an interface with backend support application in HTML5 on iPhone? Will it be secure and scalable?
If HTML5 is a markup language, then how can I make conditional statements in it? Would it be via jQuery or Javascript?
Which IDE should I use to develop an iPhone app in HTML5?
A great place to start when developing an iPhone app in HTML5 is PhoneGap.
You could either go the full-blown app route by developing an iOS app using PhoneGap, or only selecting certain tools/frameworks to help build a web-based app for mobile devices.
And very much like how it works with websites, HTML is used for the structure, CSS for presentation and JavaScript for behaviour. So yes, JS is used for conditional statements, etc.
