All, I have been working with vim for some time now, and love everything about it - there is only one thing I really miss from IDEs like RubyMine, and that is advanced autocompletion. For reference, here is my standard VIM setup: https://github.com/wrwright/.vim I have tried ctags with omnicomplete + supertab, and the one major element I miss is the ability to bring up a context sensitive list of attributes/constants/methods. For example, as I learn RubyMotion, I'd love to have some help remembering iOS SDK constants/attributes/methods, but my VIM autocomplete stops with suggesting class names

I'm using UICollectionView in an app that is displaying quite a lot of photos (50-200) and I'm having issues getting it to be snappy (as snappy as Photos app for example). I have a custom UICollectionViewCell with a UIImageView as it's subview. I'm loading images from the filesystem, with UIImage.imageWithContentsOfFile: , into the UIImageViews inside the cells. I've tried quite a few approaches now but they have either been buggy or had performance issues. NOTE: I'm using RubyMotion so I'll write any code snippets out in the Ruby-style. First of all, here's my custom UICollectionViewCell

I know how to set a navigation bar background color (with barTintColor), but now I am working on an iOS app that calls for a horizontal gradient (not the typical vertical gradient). How can I create a navigation bar with a horizontal gradient background? JulianM If you want to programmatically set the gradient of a given UINavigationBar I have a solution for you. First setup a CAGradientLayer with your desired colors and locations. CAGradientLayer *gradientLayer = [CAGradientLayer layer]; gradientLayer.frame = navigationBar.bounds; gradientLayer.colors = @[ (__bridge id)[UIColor greenColor]

I have been pulling my hair out for weeks on this niggling problem, and I just can't find any info or tips on how or what to do, so I'm hoping someone here on the RubyMotion forums can help me out. Apologies in advance if this is a little long, but it requires some setup to properly explain the issues. As background, I've got an app that uses a JSON/REST back-end implemented ina Rails app. This is pretty straightforward stuff. The back-end is working fine, and up to a point, so is the front end. I can make calls to populate model objects in the RubyMotion client and everything is great. The

I am trying to create a toggle button for each cell in my table. When pressed, it will change the image and when pressed again it will change the image again -- Toggle. In the UIButton class I don't see a selected state. I'm looking for a way to create a toggle button with UIButton so that I can change the state on each click. This is how I'm doing it in rubymotion right now using rmq @fav_button.on(:touch) do |sender| puts "pressed fav button for id: " + data[:id] + " and name: " + data[:name] #how do I change the state here? end Jan Cássio You can create toggle button easily, you just need

I'm new to objective-c and i'm having a hard time with a AFNetworking. So the thing is that i want to make a simple POST request to a server who will send me back a salt. I'v make a simple app, in order to test my request but i don't understand why i'm getting the error code 999. Here a sample of my code. + (void)simpleRequest; { NSURL *mailserver = [NSURL URLWithString:@"https://localhost:4443/"]; AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithBaseURL:mailserver]; manager.securityPolicy.allowInvalidCertificates = TRUE; manager.responseSerializer =

I have a UICollectionView in my app, and each cell is a UIImageView and some text labels. The problem is that when I have the UIImageViews displaying their images, the scrolling performance is terrible. It's nowhere near as smooth as the scrolling experience of a UITableView or even the same UICollectionView without the UIImageView. I found this question from a few months ago, and it seems like an answer was found, but it's written in RubyMotion, and I don't understand that. I tried to see how to convert it to Xcode, but since I have never used NSCache either, it's a little hard to. The poster
