I'm developing an iPad app and I'd like to use something like the NSCollectionView on it. There are SEVERAL 3rd party libs that do that. The problem is that none of them seem to support iOS 4.x. I really need to support this version of iOS. Does anyone knows a NSCollectionView-ish control for iOS that supports iOS 4.0?
Thanks!
I used AQGridView (https://github.com/AlanQuatermain/AQGridView) last year in an app whose deployment target was 3.1.3 (not 3.2 as mentioned by Scott in another answer -- that's the SDK version it requires, not the deployment target) so you should be able to use it for your project.
Here's a couple of other options I am evaluating for upcoming projects:
https://github.com/gmoledina/GMGridView
https://github.com/zorn/BCCollectionView
I'm not sure what their requirements are, I've just bookmarked them for checking out. GMGridView looks nice, I like its support for full-screen paging.
This one requires ARC and so you can't use it in 4.0:
https://github.com/kolinkrewinkel/KKGridView
But it does look nice. Overall, right now, I think AQGridView is the best fit for you.
AQGridView Supports 3.2 or greater.

Sorry if I use the wrong terminology, I'm not an iOS developer so I'm mapping everything back to equivalent features in Windows ...
If I write an iOS application that creates controls using standard UIKit functions, and I run that exact same application on various versions of iOS, will the application look slightly different on the different versions of iOS? Or does the application always use the styling of the version of iOS I select for the target version in Xcode?
And in a related question, is there a web site somewhere showing how the various controls have changed their look through the various iOS versions?
Generally no. Since iOS7 to current iOS release - all standard UIKit controls look the same. On iOS6 and lower things are drastically different. If you target iOS7 and up (As most devs do now since hardly anyone is on iOS versions lower) - you can be rest assured that all usage of standard UIKit controls will look exactly the same.
My iPhone application is developed using Xcode 5. I want to use ShareKit library in order to share images and urls from my application. The problem is, that ShareKit seems to be incompatible with Xcode 5 (thought is says it is).
Attached screenshot to illustrate my problem:
Any help (or alternative solution for sharing images and URLs) will be greatly welcome.
It seems you both are referring to an obsolete, long time abandoned version of ShareKit. Check ShareKit 2. For easiest installation I recommend Cocoapods.
Have you followed the instructions here?
(It seems like you've added objc-class.h that has no use)
Also, consider using the native sharing class UIActivityViewController for sharing purposes.
I'm starting to learn iOS development using this awesome course on iTunes U:
http://www.stanford.edu/class/cs193p/cgi-bin/drupal/
However, this course was done in Fall 2011 and is using XCode 4.2 and iOS5.
I now see that XCode 4.5 (iOS6) is out.
I just want to know if it's a good thing following this course as it's already one year old?
Or if XCode 4.2 (iOS5) and XCode 4.5 (iOS6) are so similar, that I'll just have to tweak some things a little?
I used to follow the Fall 2010 course with XCode 3.2.5 (iOS 4.2) and I stopped to start the Fall 2011... and there were so many differences that it was almost like starting over.
I just want to make sure that by investing my time in the Fall 2011 course that I'm not learning stuff I would have to learn again in iOS6.
Thanks!
Besides all of the other good info in the other answers, please be aware that Xcode 4.5 comes with an updated LLVM compiler that provides you with much improved Objective-C features. Working with properties is much easier. You no longer need to explicitly declare instance variables for properties nor do you need the #synthesize statement. The new compiler makes working with arrays and dictionaries easier plus it is easier to box basic types.
The good news is that any code you write with the older compiler of Xcode 4.2 will continue to work under the newer compiler (but not the other way around).
Also keep in mind that Xcode 4.6 will be out soon so using 4.2 will just put you further behind.
The Stanford course you're about to learn is great and it contains lots of subjects, both basic and advanced. I can't think of anything that's not worth learning from the course even though it's outdated - you'll just have to learn about what's new in iOS6.0 after you've come to terms with the more important foundations and basics featured in the course.
Have fun learning iOS
Regarding the differences between the various versions, I'd suggest you check out the Objective-C Feature Availability Index and the Xcode release notes. The major shift in Xcode 4.5 is the support for iOS 6, and you can see a list of those features in What's New in iOS: iOS 6
I think you'll be able to follow the Stanford class even if you're running Xcode 4.5.2 (or whatever). There are some minor differences, but most of those are just new features that you might not yet avail yourself of yet. Frankly, many (most?) of us are still deploying iOS 5 (or earlier) apps today, to ensure backwards compatibility with users with older versions of iOS on their devices, anyway, so if you focus on iOS 5 while you learn the basics, I think that's fine. So, go ahead and gain mastery of iOS 5 using that course, and when you're done, you can then go through the WWDC 2012 videos to familiarize yourself with some iOS 6 features and new Xcode features.
The only major stumbling block that leaps out at me (if you focus on iOS 5 targets) might be autolayout which is an iOS 6 feature which defaults to being turned on. To avoid confusion here, whenever creating a new storyboard or NIB, you may want to turn off "autolayout". If so, go to Interface Builder, click somewhere on the background, select the "file inspector" in the right panel, and make sure the "Use Autolayout" flag is unchecked.
For the record, they just updated the CS193P Web Site
They will make the Winter 2012-2013 course available via iTunesU:
Winter (2012-13) quarter's lectures are currently scheduled to be made
available via iTunesU. Don't expect them to appear the day after the
first lecture, however! There is some work involved to prepare and
publish them. Please be patient.
That sounds cool!
I've been search around how to setup panoramaGL for a whole day and none of these answers my questions. emm, maybe that's because I am new to ios developing and I start with ios5 with all ARC cool features. I did find a pretty comprehensive guide at http://www.codeproject.com/Articles/60635/Panorama-360-iPod-Touch-iPhone but it's a little bit out of date to me. I cannot follow this guide in xcode 4.3 with ios 5.0 sdk.
Emm, so here is the question, assuming panoramaGL and helloPanorama works perfectly fine in whatever xcode version and sdk version it is created in. Is there a way , without any code modification, I can import the library and using the api along with my app developed in ios5? Of course I don't mind some minor modification and I did dive into those code and comment all the retain or release stuff. but wired errors keep popping up. I really need help here.
If it finally turns out to be impossible to reuse it in ios5.0, I will probably need to write the whole thing line by line with my understand of the complicated panorama algorithm...
Thanks so much for the help!
It seems someone is working on another library based on panoramaGL. Works on IOS 5.
See http://code.google.com/p/tk-panorama/
The new version of PanoramaGL 0.1 r2 was released, please check http://code.google.com/p/panoramagl/. This version runs on iOS >= 4.x and supports Hotspots.
Please check HelloPanoramaGL example
I have no idea how to call these and so I'm having a hard time googling for it. I've seen these a several times in iOS and MacOS apps to think they might be an OS feature. I'm talking about the blue tags or groups in text field controls. See the images below.
That's an NSTokenField on Mac. On iOS there's no official implementation (file a request if you want one) so you'd have to go with a third-party implementation. If I remember correctly, the Three20 framework has one...
Googling found these iOS versions:
JSTokenField
TTMessageRecipientField (I think)
This helper class is SO much better... https://github.com/thermogl/TITokenFieldView
