Multitasking and iOs 4.0 – What it is and what it is not.
For a while there it seemed Android phones really had the iPhone beat with a certain feature known as Multi-tasking. It was all over the news and yadda yadda yada. Then Apple announced an upgrade that now includes – wait for it – multitasking. But it may not be what you think it is. We want to take a moment here to answer a few FAQs about the multi-tasking mystique and to speak another obvious question – what’s this got to do with AppUp.
First, lets talk about the concepts here. When an operating system can multitask this is its ability to run more than one program at the same time. (Not to be confused with threads which are different) This gives each running program access to important system resources simultaneously and the user gets the ability to do several things at once. For example an MP3 player bopping along while your email client checks POP3 while you’re editing a text document. When it comes to our desktop systems – we’ve come to expect this kind of behavior as minimal requirements. But prior to iOS4 the iPhone didn’t allow any third party processes (read: your app) to continue running after it lost focus. In fact, the iPhone “single-thread” experience has become a marketing point in many places and people started rediscovering the mental clarity of doing one thing at a time. It should be noted however that Apple always kept certain classes for their own use and apps like iCal were treated as a special case, often behaving in a multi-tasking kind of way. It just was something mere mortals were forbidden to do.
