I am doing an IM application with the lwuit api, In my message form I have an issue, I can't view the last message when the message's contents fill the screen, I have to scroll manually and it is embarrassing.
I have tried everything by my side but still I didn't get the solution.
I hope someone will help me out
Thanks
I have tried to do the same thing as you long time ago but the scrolling of my app became crazy. In this video you can find a similar app and in the description you can find the links to the code. Take a look on them, please.

My Post processing worked when i started my project but now that i am several months into it, my scene view turns blank and gray when i check the post processing from the dropdown. I am using Unity 2019.4 Any ideas? My first posting was deleted because of clarity without notifying me, so I have been stuck on project for days waiting for an answer that was never going to come. I don't know how much more I can say. I you don't understand my post then don't just delete it, let me know what you don't understand.
It looks like i may have fixed it. I got an error message saying that it couldn't add another camera, so i looked at the FPS. I didn't see anything wrong so I just removed it and reinstalled the FPS controller. That seems to have fixed it. Thanks for the responses.
Really really simply question.
In my own computer when I create a button with Xcode, I can see the blue outline.
But, in my office's computer I do the same thing I can't see the blue outline (and can't figure out how much bigger the button is).
What is happening?
I've recorded a video and uploaded to YouTube in order to be more clear — https://youtu.be/Bl_aOXxtIeA
PS: I've been trying to solve this thing on last 3 days, and no luck, even contacting a friend which is an iOS developer.
Folks, I just found the solution (trying by myself). Thanks for the replies too.
Im looking at adding a tutorial kind of thing to my app. Basically I want to be able to give a quick message across of what the parts in the app do. I want the users to see it once and not again. I have searched relentlessly for this but I always found app building tutorials.
A lot of games have what I want but I cannot for the life of me find how to do it or, what it is called to find a tutorial. Could someone please help me out.
Thanks in advance,
Sam
You'll need to build it yourself.
What I usually do is, on top of the view i want to explain, add a semi transparent view with some arrows pointing at stuff and a small text/button explaining it. All of that has to be modal and you can save in the NSUserDefaults if the user has already seen it/skipped it/launched the app for the first time. You'd have a method that builds all those views and you simply call it in viewDidLoad (by checking against a simple boolean value store in those previously mentioned NSUserDefaults, for example)
After many hours of googling I thought I would see if anyone knew the answer.
I have a large PDF file (30mb) which I was using the UIWebView to display but it is painfully slow when trying to scroll through pages and when you rotate the iPhone/iPad it doesn't draw properly on the screen till you have scrolled through a few pages.
So I have been looking into using the CGPDFDocumentRef to display the PDF. Before I go any further is there an easier way to do this, or any examples/open source solutions to do this before I spend a long time trying to replicate the UIWebView or something similar to display a large PDF.
I assume someone else has had this problem?
Many thanks for any help
I've been building one of these for a while now. I'll tell you, both approaches have difficulties. The CGPDFDocumentRef path is the one that I've taken, and it's worked out pretty well.
A good place to start is here, with Apple's example, ZoomingPDFViewer. You'll get a good idea of how that CGPDF* stuff works. If you're looking to put something together in a hurry, you might want to start with this guy's example. In fact, the author's website has a huge list of resources to use when you run into problems.
You guys get what I mean. I have no idea how to do this. There are no tutorials anywhere and so far I've spent about 4 hours on this to no avail. Can anyone point me to anything useful or give me a quick run down on how I would achieve this? Cheers.
In short: create a UIView or UIControl subclass. Draw thumbnail images of the pages. Respond to touch events and send selection changes to a delegate that can then update the real page. Something like that :-)
