I am using a NSSearchField to run a query over the internet and display the results in a table view. Whilst the query is running I would like to display a progress indicator inside an NSSearchField? I think I have seen this done in another application before.
Is there an open source component that I could use to accomplish this?
How would I go about doing this? What is the best way? What are the pitfalls?
The easiest way is to put the progress indicator above (atop) the search field and leave them as separate views. It used to be that view z-ordering would give unpredictable results and weren't encouraged. That's not been true for several OS X versions, now, so if it looks good and behaves as expected, I say go for it.
The harder way would be to subclass NSSearchField and muck around according to the goodies found in the Control and Cell Programming Topics for Cocoa guide.
I'd go for a custom subclass of UISearchFieldCell. Find the method that draws the background and try to add your custom drawing code there. I'd rather not fiddle with nested components. I think the one used in safari is also a custom control.
This is not my solution but I came across this question and I eventually found someone that worked out a solution and it worked for me:

I have a timeline where I basically want the user to have the ability to tap on the screen to fast forward the animation (well, more like skip part of the animation) to a later part. Obviously, this would have to be done using code.
I've researched this quite a bit and I don't think there's an easy solution. CCBSequence and CCBSequenceProperty offer a bit of hope, but my ideas have run dry and can't see a way to do it.
Obviously I'm aware of the animation manager and using it to run timelines and stop timelines, or even call something when the timeline is completed, but my capabilities with manipulating timelines made in Spritebuilder doesn't extend too far beyond that.
I can think of a messy workaround, where basically I just duplicate the section of the timeline I want to skip to and when the screen is tapped stop the current timeline and go to that, but it seems cumbersome and messy and I'd like to avoid that if possible.
Thanks for help!
I found the easy solution after a bit more looking
So if you have a look in CCAnimationManager there is a method for this called:
- (void)jumpToSequenceNamed:(NSString*)name time:(float)time;
So with your node you can call
[node.animationManager jumpToSequenceNamed:#"MyTimeline" time:1.0]; // 1 Second
If your animations aren't extremely complicated, try to implement it via cocos2d actions http://www.cocos2d-swift.org/docs/api/index.html
Using engine API you can create animation with custom speed on every tap.
I'm wondering how to make a window "grow" like the Xcode's one when it opens...
(of course I'm using Xcode to make that window, and I'm on Mountain Lion)
For starters look here: https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/ApplicationKit/Classes/NSViewAnimation_Class/Reference/Reference.html
NSViewAnimation. Despite its name, it works on windows as well.
You can also look here: http://cocoadev.com/wiki/AnimatedWindowOpening
EDIT
I haven't tried this, but it looks promising. animationResizeTime: part of NSWindow, I believe should change the animation time. Now, I am assuming that all window actually have this animation, which I read somewhere that it does, however Xcode has extended the time. Perhaps .2 seconds wasn't enough.
That might only work if you use this: https://developer.apple.com/library/mac/documentation/Cocoa/Reference/ApplicationKit/Classes/NSWindow_Class/Reference/Reference.html#//apple_ref/occ/instm/NSWindow/setFrame:display:animate:
Good luck.
Edit
According to CodaFi, you can simply use this in the Interface Builder. Select your window and change this setting. However, I can not seem to get that too work. Therefore I am running out of ideas. You could also look at this, although not exactly what you mentioned, it may guide the right way: Resize NSWindows with easing animation
I'm trying to create a menu for a local multi-player game that dynamically updates when peers become available on the network.
The interface I want to implement is a UIScrollView, where each page displays information about a peer. Ideally, these pages are added and removed when a peer's availability changes.
I have looked through several tutorials using UIScrollView, but they all seem to pull page information from a plist or pre-loaded array.
What I want must be possible; weather app behaves in a similar manner, dynamically adding or deleting location pages. I'm not sure where to turn for further help, though. How do I dynamically update my scroll view's contents as outside events occur?
I decided to go with UICollectionView instead, it seems to provide a better method of implementation for what I'm trying to accomplish. Thanks!
Have a look at this Ray Wenderlich Tutorial.
I've used it as a basis for doing a paged scroll and the mechanism is simple enough to extend to whatever dynamic scheme you would like.
You can check this site for Multiple Tutorials & examples for UIScrollview. The link:

I am sure, you'll able to find some good code for your need. Hope it works for you.
I just wanted to know how you could implement a bookcase, like in iBooks, into your iPhone app.
I presume you would need to use a UIScrollView, but then I read somewhere that you need to use a UITableView. Which is it?!
You'd use code that others have already written, such as AQGridView.
I'm not sure if there's a better way, but you could create multiple small views or images (these would represent each book) then add these small views/images to the subview of a larger view in a linear format (leaving a space between each element). Then just set the background of your larger view as an image of a bookcase. Sorry I don't know of a better way.
And for the above solution I would use a UIScrollView.
You can implement it anyway you like, but it seems to me that a UITableView would be the easiest (which will scroll anyway). All of the magic will happen in your UITableViewDataSource, which is where you will decide what books are placed on what row.
Once you have decided which books to display you will have create a custom tableview cell that draws the appropriate objects.
To be honest, while not too difficult of a task, it will take a lot of effort to get looking right. If you are not comfortable with custom drawing then be prepared to spend time learning about the various image/graphic APIs.
I'm working on a little program and would like to implement a menu in the style that is used in the Front Row application. I know this is an extremely open ended question but what would be the best way to go about creating such a thing?
I thought I could maybe use a NSTableView but from the looks of it, that seems overly complicated to get the scrolling to work correctly.
I'm wondering if I should just code my own menu view from scratch but wouldn't really know where to begin to start that.
Any thoughts or pointers would be great.
Thanks,
Apple provides sample code that shows how to implement a fullscreen, list-like menu:
https://developer.apple.com/library/mac/#samplecode/CoreAnimationKioskStyleMenu/Introduction/Intro.html
The code uses no AppKit classes (like NSTableView). The UI is made with Core Animation.
Another good core animation sample to create Front Row like Menus can be found in the following blog post:
