Trying to create a collection view with evenly distributed cell

Hi, I'm trying to create a 3 cell per row collection, and I want no margin (horizontally or vertically) between each cell. So in xcode I set Min Spacing For Cells / For Lines to 1, Indicator insets (all 4 values) to 0, then I write code like this: - (NSInteger)collectionView:(UICollectionView *)

Binding to a view's model object

I have a xib with a top-level view and a bunch of subviews which represents one view of a given model object. The top-level NSView subclass has a readwrite property which is the model object of which it's a view. I thought this was a pretty standard pattern, especially in OSX which only just rec

Adding constrains for anonymous buttons

Hi, I'm trying to create a "label group", so I decided to generate 3 buttons and put them in a single line, evenly sized and evenly spaced. But these buttons are un-named, is it impossible to use constraintsWithVisualFormat now? e.g UIButton *buttons[3]; for (int i = 0; i < 3; ++ i)

Re: Binding to a view's model object

I think you can bring an object controller into your xib from the IB pallet. Bind the content object of the controller to your NSView subclass and expose the binding of modelObject.someStringProperty through the object controller's attributes inspector panel. The all your subviews will bind to

What's the right way to use UIActivityIndicatorView? After it's stopped

Hi, I'm trying to show another UI Control when the stopAnimation method is called. But in xcode if I drag the UIActivityIndicatorView first, any other UI Control seems to be replacing it. Now it looked like I had to do create the other UI Control and add it manually when the animation is stopped

I agree that it sounds like a memory management bug. Especially since you aren't using ARC. Try turning on NSZombies and see if it crashes at a more helpful point. http://michalstawarz.pl/2014/02/22/debug-exc_bad_access-nszombie-xcode-5/ On Sun, Jan 25, 2015 at 4:57 PM, Trygve Inda wrote: >> On

Any way to force a window under the menu bar?
