I would like to know, what limitations there are for how far one can go in terms of replacing UI components of current touch screen smart phones, in particular iPhone, Blackberry and android based phones.

Hi all, This seems like a straightforward google search answer, but after a while, I still can't be 100% sure of this.

So I just want to be sure if I can only have P2P with Bluetooth or if I can have like 4 iPho...

Problem: My app must run on iPhone OS 3.0. However, there are some features of iPhone OS 3.2 which I really want to use. Just as a little add-on for free. But I don't want to cut off my user base by doing this. Imagine you're an iPhone OS 3.0 thing, and someone gives you a book to read. It has iPhone OS 3.2 instructions. You never lear...
A CAShapeLayer uses a CGPathRef to draw it's stuff. So I have a star path, and I want a smooth drop shadow with a radius of about 15 units. Probably there is some nice functionality in some new iPhone OS versions, but I need to do it myself for a old aged version of 3.0 (which most people still use). I tried to do some REALLY nasty stuf...

I have a XIB where I replaced the UIView with a UIScrollView. I made sure the outlet to File's Owner:view was linked to the new UIScrollView. I'm trying to add a UIImageView to the UIScrollView programatically now. That's not a problem, but then I'd like to change the contentSize of self.view to match the new UIImageView. I've tried (...
Is there a way to tell a UITableView to preload all rows? The tableView is supposed to show several comments (up to 80 comments). So my CommentCell uses a Setter to adapt the cell to a specific comment. -(void)setComment:(Comment *)newComment { if (newComment != comment) { [comment release]; comment = [newComment retain]...
