I have working program with Wrapping Text Fields, and I would like to add vertical scrolling. I have found that there is Text View object in xcode library and it has NSTextView in NSScrollView. The problems came when I simply tried to substitute Text Fields with Text View. First, when I made outlet, this outlet belongs to NSScrollView (no NSTextView), and NSScrollView doesn't have String type, which I need for working code. Second, when I deleted NSScrollView (I don't know if it was right to do this) and typed instead NSTextView in outlet, I could use type string, but code didn't work. What I did wrong, what should I do ?
Add an UITextView
Drag an outlet from it to your class
Make this class implement UITextViewDelegate
In code, set this text views delegate to this class
It is really simple, I'm confused by steps you took to try to get it working.

I have a simple question. I have my NSView which is detecting drops (drag and drop). When user drops a link with image from browser, I detect that action, create NSImageView, initialize it on a place where user dropped it with some default frameSize and put the image from the link into it.
I would now like to highlight that NSImageView when user clicks on it. I also want to implement moving around that NSImageView in NSView but I'm pretty sure I will manage that. How do I highlight that exact NSImageView which was clicked? I haven't created earlier that NSImageView in interfacebuilder and assigned a special class for it so I can use drawRect, I have just created it dynamically...
Any help would be appreciated.
You can use NSImageView's setImageFrameStyle for highlighting.
So I'm just trying to create a very simple app for demo purposes here:
Created a Single View Application, using storyboards
Added a UIView to the storyboard
Added the following code to my controller's header file:
#property (weak, nonatomic) IBOutlet UIView *myView;
Now, I understand that I can link the UIView to the controller by:
arranging my code such that the header file is next to the storyboard
holding down Ctrl key and dragging it to the property in the header file
My question is this: can I do this without Ctrl-drag? And if so, how?
More specifically - it's annoying to have to put both my header file and storyboard on screen at the same time, and it seems there should be a way to make this connection without doing so.
I also understand that I can manually place the view by creating it inside my controller's viewDidLoad function, but I'd really like to use the interface builder to simplify / visualize things.
Edit: Is the answer to my question affected whether I use storyboards or xib/nib files? (I'd switch to use the one where it works)
you should be able to right click the element, and drag the "referencing outlet" item to the view's "File's Owner" in interface builder. There, it will give you a list of all available IBOutlets (matching the object's type).
In addition to Dima's answer, you can just as well use the Connection inspector in the Utilities pane
I still have a lot to learn with cocoa so I may have missed something obvious here. I have a custom view I would like to display in an nssplitview which replaces the current subview there.
I have a MessageView.xib file, and a MessageView .h/.m which subclasses NSView. I created a custom view instance for my main window (the one which contains the nssplitview) through Xcode 4's built in gui builder. I created an outlet to this instance of MessageView in my window's controller.
In my controller for the window when I want to swap out the subview for the splitview it runs this
[splitView replaceSubview:[[splitView subviews] objectAtIndex:1] with:viewMessage];
viewMessage is the outlet to the MessageView.
When this code is run the display of that subview changes to be blank. I'm not sure if there is something wrong with my custom view or there is some size issue. Is there something I need to do to fit the view into the split screen view or is my custom view just not displaying correctly? I have had a difficult time finding a tutorial on creating custom subviews with Xcode 4 so I'm not sure if something could be wrong with that. The custom view just has a label and a textfield in it.
Generally, you shouldn't need to replace NSSplitView's subviews with your own. Rather, you add your own custom view(s) as child views of the default subviews on each side of the divider. You can do this in code with addSubview:, but it's probably easier to just use Interface Builder in Xcode. Drag a "Custom View" into the splitview, then in the Identity Inspector, under Custom class, change the class to the name of your custom NSView subclass:
I think (off the top of my head, not tested), if you really do need to replace the default NSSplitView subviews with your own class, you can probably do it in Interface Builder using this same method, but selecting the default subview itself and changing its class in the inspector. This doesn't work for all AppKit classes, but it may work for NSSplitView.
I have a UIView filled with buttons that are all nicely hooked up to actions and outlets. However, in my infinite wisdom, I decided that I really would rather have the button behavior to be different and subclassed a UIControl.
My plan was to hop into Interface Builder, change the class of the buttons to my new UIControl subclass, and then be up and running. This would preserve all of outlet and action connections.
In IB (View Identity Inspector) when I type in my UIControl subclass into the class field, it reverts back to UIButton when I tab out. Any UIButton subclass works, but not a UIControl. I can go down the inheritance tree but not up....
The first plan was to go to XCode and change the superclass of my new control temporarily to UIButton, change the 'class' of my IB buttons, and then change the XCode code superclass back to UIControl. IB accepted and changed the class, but running the app gives me non-visible buttons. The IB Attributes inspector still shows it as a button.
Creating the control from scratch and rewiring works, but I was hoping to not rewire all the buttons if it could be avoided. (This is a change I was hoping to roll across multiple apps, so it is a bit more painful that it sounds)
Anyone know any way around this?
many thanks!
I'm a year late on this, but maybe it will help someone in the future. Perhaps you could open the .xib in a text editor and figure out what text you would have to change to get it to work (try it on a sample project first), then use find and replace to fix all of them at once.
I am trying to make an editable text object in cocoa that contains no input box (just the text). I have tried doing this using NSTextField but setDrawsBackground: NO and setBordered: no have not helped. Is there another method for NSTextField that will do this or do I need to use another class? I looked at NSText but this class seems to just be the same as NSTextField with less functionality.
You're headed in the right direction. Are you missing - setBezeled:NO?
It's fairly simple to get what you're looking for through Interface Builder. The only changes required (from its default instance) are to set the border to the dashed (invisible) option and uncheck the Draws Background.
