Vote count: -1 I want to lea Ruby, and I want to get more experience doing Android development. Is using RubyMotion a good way to achieve both goals at once? What are the downsides of using RubyMotion? The primary goal is leaing as opposed to other considerations like integrating with an already existing body of Java code, taking advantage of my Java skills, etc. asked 2 mins agoKartick Vaddadi Let's block ads! بخوانید...

Vote count: 0 See Merging multiple custom observables in RX for background. My scenario is that I have a number of arbitrary sensors (hardware). I have written some pluggable modules that can coect to these sensors in C#. They currently each use a thread to run an acquisition routine on a timer. The larger goal is to change polling to RX as well once I understand how! There is a requirement to monitor these sensors in groups so I was thinking there would be an aggregated topic where a monitor could subscribe to for updates from a particular group of sensors (Temperature, Signal Strength etc) and potentially make changes to the behaviour of the system based on the readings from the sensors.

Vote count: 0 I have looked at various solutions posted i.e. parsing, substrings and splitting and none of them either produce a value or the required value.

Vote count: 0 I want to create a series of different color sprites using a single gray scale image: For example, if I use blue color with blendingMode: .Color in a software (Sketch, AI, etc), I get: Then I create a subclass of SKSpriteNode, use init method like this: init() { let image = UIImage(named: "gem1") // let image = UIImage(named: "gem1")?.imageWithRenderingMode(.AlwaysTemplate) let coloredImage = image?.blendColored(someColor, blendMode: .Color) let texture = SKTexture(image: coloredImage!) super.init(texture: texture, color: UIColor.clearColor(), size: texture.size()) } But I get the sprite like this: Definitely not what I want.

Vote count: 0 I am porting an Android app to Swift IOS. The Android app currently employs a custom split pane view as a child activity. The functionality of the UISplitViewController fits the bill perfectly for the IOS app, however Apple state: You caot push a split view controller onto a navigation stack. Although it is possible to install a split view controller as a child in some other container view controllers, doing is not recommended in most cases. Split view controllers are normally installed at the root of your app’s window. For tips and guidance about ways to implement your interface, Has anyone founs a way around this limitation using Swift? asked 47 secs agoRatatat Richie Let's b...

Vote count: 0 Can anyone provide assistance for using a text field inside a UiCollectionView. What I'm trying to accomplish is a collection view that holds images for a user to post. With these images I'd like to give them the chance to caption each individual image. The issue that I'm having, which I'm certain other's are having is this; once a user types in a text field the input automatically fills a text field later on. Example: 5 Images with text fields. Image 1's caption user types "hello" Image 2's caption user types "there" Image 3's caption user types "how are you" Before user types anything in the text field for Image 4 it would read "Hello" I've found one posting on stack to be be...

Vote count: 0 I have this method that retus true or false based on whether a website has any pages that have any exteal links. The method does work. However, it is incredibly slow.

Vote count: 0 I have a Swift iOS8+ app that receives remote push notifications from a 3rd party server over which I have no control. That server sends push notifications as JSONs with the usual "alert" and "badge", but does not send the "sound". Consequently, my app plays the default alert sound for push notifications. Is there any way to programmatically override the sound, so that I can play my own, custom remote push notification alert sound? Or even programmatically mute the sound? Remember, I caot force the sending server to change the push notification payload to include a different sound. I began by placing the sound file (ding.aiff) in my main bundle, but there seems to be no way of ...
