  • Push a detail view in UITableViewCell class

    - by luca
    My class inherit from UITableViewCell, i have make some custom transitions to push a new detail view when an image get selected. [UIView transitionWithView:self.masterView duration:0.5 options:UIViewAnimationOptionShowHideTransitionViews animations:^ { [self.masterView addSubview:self.detailImage]; } completion:nil]; My code works fine, the detailImage subview is shown with a transition, but this transition is not what i want exactly. What i want to perform is a simple transition from bottom to up. The list of UIViewAnimation doesn't contain such animation. Is there any way to use that transition without changing my class inheritance to UINavigationController ?

  • Image visualization with canvas. How to resize them?

    - by Luca Matteis
    I'm building a website photo gallery for a friend. Images are loaded as simple DOM image objects (<img src="" />), and the size of these images is based on the browser size. So I resize them with CSS. This isn't an optimal solution since CSS resizing seems to change the quality of the image and pixelate it quite a bit. I was thinking of rendering the image with canvas and then resize it with that so that the quality remains effective, but I can't find any info about this online. Any ideas?

  • Resizing the imageView in a UITableView

    - by Luca
    Hi! I Created a grouped table view, and I noticed that placing an image in the imageView results in an image that is too large. It overlaps the rounded borders of the cell, which is horrible. I tried looking for a way to resize it, but I found many answers that didn't quite satisfy me. How would you do this? Which is the simplest way to go? The solutions I found where strangely complicated. Thanks!

  • Why does Apple use Objective-C for iPhone development? (App Store)

    - by Luca Matteis
    I'm interested to know your opinion on why Apple uses a language such as Objective-C for app development. Does Apple's app store allow apps written only in this language? Does apple even look at your source-code or does it just care of the binary output? I learned that most of their app rejection (in the app store) is based upon apps crashing (probably memory leaks in which Objective-c is not very efficient unless you use a GC). Why not let developers use a safer language, like a scripting language? I think these are important questions for a developer (I don't even use Apple's products) because it seems like Apple's app store is the MOST successful app sale place on the web.
