I am posting the question again with more clarity.
I am trying to develop a component similar to the UI for timeline component in "Timeli" app.Ia m not sure how to start or which iOS controls to use for this .The requirement is to show the years in a horizontal table view.Pinching on the tableview should expand that particular cell and at some particular point the cell should break into the different months in that year.If the user further try to expand a particular cell by pinching then that cell should break into the different days .Reverse should also work.It would be great if anyone can help me with some tips or suggestions to star developing this.
I don't know that particular app, but I can give some general advice: browse through the open source components at Cocoa Controls; find one that is similar to what you want to create; download the source code and study it.
Even if you can't find exactly what you want, you might learn some techniques that will help you figure out how to build the control you want to build.
If you want more specific help, you're going to have to make an attempt, and then ask a specific question where you explain what you're doing and what's not working. Generic "how do I build this?" questions don't usually work too well here, because nobody knows where you are starting from.

I wanna perform like find differences game in a a flutter app but I did not find any package can help so the idea is that I have two similar images with some differences like removed parts of color change parts and I want to find the exact location of this differences so that I can make it clickable to tell app that user select right difference or not
I will appreciate an help and if there is another idea I will be happy to hear
I am relatively new to Flutter and just building a Web App for learning purpose. If someone knows Taxfix, which is by the way amazing!, I am wondering how they did this really nice question and answer design? LookHere Sorry that it is in German, but I hope you get the point.
How could you achieve smth. similar? I guess the Main part is a ListView?! And then just dynamically somehow create new questions out of the answers before? I guess the StateManagement is the key?
To concrete the question, how could I achieve a ListView, showing only one item per page and adds dynamically new questions based on the answers before? Does someone has a really short and basic example und how to get something like that running?
Sorry if that is a dumb question, but maybe someone has implemented already an example like that.
Anyway, thx for the help,
Daniel
how could I achieve a ListView, showing only one item per page
with listview you can use change the scroll direction to horizontal
|-listView
|-myfullscreenwidget which scrolls horizontally
adds dynamically new questions based on the answers before
this is mainly a datasource question. you might want to ask this questions first
Is the data source local or online
Nature of questions, bool, multi-choice, short answer,
How to validate response
finally communicate with the database and push more questions to the list
I'm pretty new on this list, and trying to answer a question posted here on StackOverflow and i am wondering if there is some standard way to post entire models here, not just the "CODE" tab portion. Or for that matter even an image of the view screen.
I don't see any place to put attachments on posts or answers. I suppose I could upload the model to the NetLogo-users Google users-group, which does have a place to upload files, and cross-reference it here. I suppose I could try to open an email channel to the user and send them email with an attachment. I suppose I could post it on GitHub.
But is there some way to attach a full .nlogo file right here that I'm missing? Some interfaces are really complicated and only looking at the CODE tab is not adequate.
And, yes since the .nlogo model is pure text I could paste the entire thing into a window here ( which would object to having code in a text window of course) but that's a lot of extra characters in the post.
Unfortunately there is not. This is actually more of a problem for the questioning than answering as it can be difficult to get the person asking the question to post the relevant bit of code, including the other bits of code that lead up to the problem and give key information like what the contents of a variable may be. NetLogo does not lend itself to MWE at all, and beginners simply don't have the experience to replace interface variables with global variables etc.
Uploading to Google users group and cross referencing is likely to get the question/answer closed as it's not complete. But StackOverflow has a different purpose than the users group - it is supposed to be focussed on specific questions with specific answers - such things as syntax problems and bugs, not design. The last thing we want is interfaces or full models. We tend to be more lenient than other areas of StackOverflow because we know NetLogo has a very high proportion of beginners without support and that MWE in NetLogo doesn't really make sense, but questions that require full models are definitely out of scope.
I need smooth page curling for my ebook without clicking any button just like in PageCurl demo. But in that code they are using a pdf file(CGPDFDocumentRef). And am using a xml file for my ebook. How can i implement this? i tried to do but no use. Kindly help me.
You should start by reading the basic documentation and doing some google searches, then when you have specific issues about implementing things in the docs, or questions related to understanding how to apply something in the docs, you should come and ask those specific questions.
You can also start by accepting some answers on Stack Overflow for some of the previous questions you've asked.
To get you started, take a look at UIGestureRecognizer and make sure you read the iOS Application Programming Guide
We we wondering what are some ways developers have added a help function to their apps. What are some techniques people have used?
One way we were thinking of is to us UIWebView to display a HTML file with help instructions.
Thoughts appreciated.
I'm using UIWebView right now which pretty much contains all the help in a single page, along with some JQuery things to display popups, etc. But I like the way iCab Mobile (et al.) are doing things which is a sectioned UITableView with each row a separate topic or section within their overall help information (complete with icons...) then in their bundle they have each section in its own html file, organized by localization.
Another thing in my queue for the next release is to provide a dynamic "News" view. The rough idea is as follows... I have on my server a file or CGI where I can place small bits of news I'd like to push out to users. On startup, my app checks for network availability and if present, start a thread to see if anything has changed on the server since last updating the News data. If changes present, post an alert letting user know, and asking if they'd like to read it now. At that point, the latest news is already downloaded and cached, so they can simply read it later if they want, and I won't post anymore alerts until the server file changes again. (And one could add a preference/setting to disable these alerts.)
I'm thinking this would be a good way to let people know that some nasty bug is known and fixed and an update is sitting in the queue, solicit beta testers, promote upcoming features or other apps, etc. I can see where constant alerts everytime I've got something new to promote would get annoying, so having a setting to disable them means the user never has to read them unless they want to. Although some kind of override to warn of recently discovered/fixed bugs seems sensible.
FWIW, the author of Mover+/Mover has just started doing a similar thing, though I think Emanuele is perhaps only showing one Notelet at a time, whereas I envision a bit more of a history (shown in UIWebView) until I decide to age stuff off the bottom of the stack.
I'm using a scroll/page view to show several images containing small notes. Each image then tells the user about the more advanced functions on a specific part of the app.
In my opinion the help should only contain information that isn't a 100% relevant for the use of the application. It should be things the advanced user should use to make more use of the app. It should contain gold for the power users. The "basics" should be so obvious that no help would ever be needed. If that's not the case, I think, you've failed as a developer on the iPhone platform.
(Here's a screen shot from my demo app)
I'm currently creating a fairly complicated app. I'm thinking of doing help as a semi-transparent overlay - help in text form is hard to swallow for users; it's much more helpful to just point at stuff and say "this does that".
