First off this is Xcode 4 iOS 5.0. Here is what I want to do. I have one view, we will call it view1, which has a button and when that button is pressed a different view with a table appears called tableView. I have multiple images I want to be in this table and when the image is selected, it would appear in view1. I have already researched all of this and just can not find the right material. The button and table are already working together and I can add the objects to the table, but getting those objects that I select to appear on view1 is what I am not understanding. I can not get the two nib files to work together, or Im going at it wrong.
Second question, guess this is similar, view1 displays an image that is selected from the photo library BUT is there a way to open the photo library, select the photo, and have it appear in a DIFFERENT nib view? Again this is getting the NIBs to work together. I would appreciate all the help I can get. (photo library and selection of photo already works so that code is not needed). Thank you for the help!
I have used this example to get what you have described in the above question. But with some tweak in the delegate methods and hop you will get some direction for your problems, too.
Good Luck!
Happy Codding! :)
And need any help just ask for it, don't hesitate.
It is possible from delegates in other class.

I have UIImageViews in three different view controllers displaying the same thing, that being user's profile pic. I want them all to update at the same time when the user changes his/her profile pic using imagepickercontroller. I thought about outlet collection, but I believe they don't work across different view controllers. I am out of ideas on this one, any help would be greatly appreciated. Thanks.
I think there are few solutions for your problem. One of them is using your profile image as global variable. Then whenever you move to a viewcontroller, in their viewWillAppear, assign the profile image to the UIImageViews.
It's simple, isn't it?
It's really strange. The Prototype-Cell in my second UITableView isn't on top as it should be:
If I start moving it, than it's on top again, but after i drop it on my View, it is still in this strange way.
How can I change that?
As you see, the first Cell is okay, but the second isn't.
Well, it's difficult to understand using only an image, but I will give you some possible causes for that:
Have you applied a table header view by accident in the second table view? If you did, removing it will be the solution
Have you applied the proper view constraints in the table view and its cells?
If I were you, I would not try to embed two UITableViews in the same view controller this way, especially since you use storyboards with iOS 7. What I would do is to use embed segues. Just drag a container view for each of your view table views, and connect their embed segues to their appropriate table view controllers ( you need to create in the storyboard those, two). That way, you can set the constraints much easier, separate the logic between the two and have a cleaner interface. You can do that and see if that helps.
I still have a long way to go learning Cocoa. I'm trying to learn to code a Table view just like the finder where there is a small icon to the left of the file listing. #1 Its not clear to me if those are two columns in a row or if that type of operation is handled as 1 column.
If someone could point me to a good, easy to follow example, I would appreciate it. I was able to follow one example and I can drag and drop files onto the view but it only displays the [files lastPathComponent]. I wasn't sure how to add the icon.
You are going to have to subclass NSCell if you want this. Here is a good example:
NSCell Image and Text Sample
While yes you could do as sosborn suggests, however if you're already using OSX 10.7 Lion, you can now (and should!) use NSViews instead. And specifically you can subclass NSTableCellView.
Personally, I would watch the WWDC video titled "View Based NSTableView Basic to Advanced" available here: https://developer.apple.com/videos/wwdc/2011/
This also includes sample code that will get you going.
I looked for this on the web, but I could not find any clear tutorial on how to successfully implement an NSCollectionView. How should I proceed?
In Interface Builder, I can drag an NSCollectionView to the main view, and I see that there are two other new views in the documents window: I suppose one is the actual NSView inside the collectionView, and the other one is the NSView prototype for each of the elements that will be displayed inside the collection.
But from now on I don't have any idea about what to do.
Any help would be very appreciated, but thank you anyway in advance.

The Collection View Programming Guide contains a step-by-step tutorial. (In fact, that's all it contains at present.). The sample app IconCollection is all set up with reasonable bindings and code to show how the collection view works.
I want to build a Cocoa App with a list of entries very similar to the ToDo list of Things.app (see the screencast). The question is whether I should use
a TableView,
a CollectionView or
a WebView.
I think it could work with all of them, but which one suits the following requirements best?
have a list of entries -> 1 column & many rows
reordering with drag & drop
select single entries & use keys for actions like delete
open up an entry: the row should expand to show more input fields
customized look: rounded corners, shadow, background gradient
So far my research says that the TableView has most of the functionality, but is harder to customize in its appearance, the CollectionView doesn't have drag & drop (right?) but is easy to design and the WebView would take much effort to not hurt the user experience and I can't bind my model directly to input fields.
What pros and cons am I missing and what would you recommend to use?
A WebView doesn't make sense. You might as well create a web application if you use a WebView. An NSCollectionView is more for grid like data, like TV listings per hour.
NSTableView is the only one that makes sense in this case. I've implemented all 5 bullet points with with an NSTableView without issue. You need to extend NSTableView and do some custom drawing for the customized look. That's the hardest part.
open up an entry: the row should expand to show more input fields
You need an outline view. A table view is for flat lists.
Note that NSOutlineView is a subclass of NSTableView, so all the table-view features work on an outline view as well.
There are people who've done this already. One that I've used successfully is by Matteo Bertozzi and is available here: http://th30z.netsons.org/2009/03/cocoa-sidebar-with-badges-take-2/ It might take a bit of massaging to get it to work properly (especially if you need complex drag-and-drop behavior), but for basic functionality, such as getting the section titles and items in the list, it works excellently.
Edit: This has come up before and is a common question on the cocoa-dev email list. Here are some other options.
Just took a look at Things.app itself using "F-script anywhere".
They've used a subclass of NSTableView called "DetailTableView" which presents the condensed todo items. Collapsed todo items are implemented using a custom cell called "ToDoCell", but the expanded look you get when editing is interesting. In that case they've got a custom view called "ToDoEditView" which is inserted as a subview of the DetailTableView when required. I suspect this editing view is temporarily added as a subview in the correct location and the corresponding row of the tableview gets resized temporarily while it is present.
All pretty speculative .. I'd love to know the details of how this was done. It's an awesome UI.
I'm approaching the very same problem in my app (with one big list similar to the Things todo list) and I think a table view would make a lot of sense here.
The trick is having your cells ("rows") expand when double-clicked. That's about all the progress I've made so far.
