The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome.

This is a dupe of Can you use MacRuby to develop applications for the Mac App Store? (more or less).
ReplyDeleteIs it possible to build an iPhone app
using MacRuby alone, without any
knowledge of Objective-C?
In short, no.
All of the APIs (system frameworks), documentation, dev tools, examples, and the majority of the development community use Objective-C. You are going to have to know Objective-C through and through to be able to write an app against the iOS or Mac OS X system APIs anyway.
As well, the MacRuby runtime uses the Objective-C garbage collector that ships with Mac OS X. While porting that collector to iOS/ARM is likely not that hard (the source is available), the system frameworks don't support it; it won't work.
MacRuby is not yet ported to iOS.
ReplyDeleteAn Apple engineer revealed on Twitter last September that work is being done to port MacRuby to iOS.
Until such a release sees the light of day, however, you will not be able to use MacRuby to write iOS apps.
Apple recently let it become known that MacRuby is to be included with the next release of OS X. It certainly looks like MacRuby may be on its way to becoming an Apple-blessed means of developing apps for OS X and iOS. One can only hope at this point, but these early indications are promising.
