I'm trying to figure out how can I solve a problem.
Basically I have a Dynamic TableView, with dynamic Images(Different Sizes).
I want to set always a fixed width:320 for the UIImage and use the Mode: Aspect Fill(Without Clip Subviews), the image maintains the width and set the height dynamically based on my width, but the problem is, my image cover up everything else, like labels, buttons and edges of my cells, I tried to use auto-layout with constraints to reposition these other components(labels,buttons,etc), but not worked.
I don't know if just using the Interface Builder I can solve this behavior or I need to check/calculate some information programmatically.
Any ideas are welcome.
Thanks Team!
Due to lacking of your code as example, I can just suggest you use a swift library from GitHub called Toucan. Toucan is a Swift library that provides a clean, quick API for processing images. And it solve my image problem smoothly.
You should be able to solve this in Interface Builder.
I usually am always able to accomplish my desired layout using constraints and priorities. Only in cases with dynamic type it gets difficult.
I don't know the layout of your cell. It would be helpful if you would post a screenshot of your cell and indicate where the overlap occurs.

I have weird problem on iOS 8 with dynamically resizing table cells.
While I scroll down table, cells which come in and appear seems to fly in. It looks like cell adjust width to fit iPhone 6 (like stretching from wider size).
How to prevent that strange behaviour.
read and learn about reuseIndetifier, it will speed up cell rendering and a must to use. And post code next time :)
iPhone - What are reuseIdentifiers (UITableViewCell)?
Definitely I know how to use reuseIdentifier and I do it.
Problem is completely different, maybe someone else met that kind of issue.
I have NSSplitView with NScrollView inside it and view-based NSOutlineView inside NSScrollView, it has e.g. one column. My outline view must be scrollable vertically only and it must consider minimal width of column content to fit it. I think they must return -(NSSize)fittingSize with values {minColumnWidth, 0}, but it returns {0,0}. How can I do that?
Try to return the desired view size in (NSSize)intrinsicContentSize. I am not sure if I totally understand your scenario. You could add a screenshot or wireframe to make it easier to understand the setup. Whatsoever, take a look at my question dealing with a similar problem.
Maybe also check out the WWDC Session 232 - Auto Layout by Example. It covers a new split view API together with Autolayout (starting around 41:00 minutes).
I'm wondering how to implement views similar to the conversation views in mail (for Lion).
http://images.apple.com/macosx/whats-new/images/mail_conversation_screen.jpg
I want the effect where it looks like a sheet of paper laying on the background.
I'm thinking that it may just be a view based table view.
A nudge in the right direction would be fine. Just need to know where to look to find out how to do it.
Thanks in advance.
It could be a view based table view or just a normal container view with some simple tiling logic (ie, "roll through each subview and set their frames"). The effect you're looking for, though, can be easily accomplished with layer-backed views with a background shadow enabled.
There are several perfectly valid approaches to this goal (the layout and drawing parts). Pick one, start down the path, then post questions as problems arise.
I'm doing something with cocoa which I think is a bit complicate for a beginner like me. I tried a few things, but I admit I need some theory first, because I would like to understand exactly the meaning of this concepts.
I see that every NSView and every class that subclasses it has one thing called frame, and one called bounds. They both have a size with width and height and an origin.
I have an NSView with an NSTableView inside of it.
I have the size of a row from the table view, and I would like to set the height of both NSView and NSTableView equal to rows*rowSize, in a way that the group NSView+subviews is automatically resized when an object is added or removed to and from the data source of the Table View.
I made some experiments, but I did end a bit confused about frame, bounds, sizes and so on. I don't know what I should change and how.
Can you please give me an hint about what bounds and frame basically are, and how can I achieve that magic resizing?
Thank you for your replies in advance. Best regards,

The difference between frame and bounds is covered very nicely in the View Programming Guide (under View Geometry).
You'll also want to peruse the NSView Class Reference, where you'll find some handy notifications, such as NSViewFrameDidChangeNotification and handy methods such as setPostsFrameChangedNotifications:.
I've been banging my head about this seemingly easy task and I could really use some help.
I have a wide Image loaded in the gui (using the designer..) and I want to be able to draw only a portion of it, a rectangle.
I need to be able to change this rectangle position over the large image, in order to draw a different part of the larger image at will. In this process the rect must maintain its size.
Using the Ui::MainWindow object I'm able to access the label holding the image and a solution that involves using this option is preferred (in order to keep up with the rest of the code I've already written )
Any solution will be much appreciated :)
Thanks,
Itamar
I would definitely (for ease of use) just place an empty label as placeholder in Designer.
Then implement the paintEvent for this label (delegate it to your own method). You'll have also have to look into QPainter, QPixMap, etc... Should be doable based on these hints and the documentation.
If you want more, I suggest you provide a small code snippet to work upon.
If you want to do this more or less purely through designer, you could put a QScrollArea where you want the portion of the image to appear. If you set the scroll area's scrollbar policy to be never shown, you can then manually change what part is visible via the scroll area widget. However, this would probably be more complex that creating a derived widget and reimplementing the paint function.
