Oops, that should be:

[[theTextView textContainer]  setContainerSize:NSMakeSize(FLT_MAX, 
contentSize.height)];

Re: How to Truncate lines in NSScrollView/NSClipView/NSTextView Combo

[Dave]

Hi,

I did do quite a few searches but I didn’t find that - I’m not that good at 
formulating the correct search string, I think was trying things like 
"NSScrollView Truncate Text”.

Anyway, I managed to piece together something that would and I created a 
Category method on NSScrollView so I will (hopefully) never lose it again.

Cheers
Dave

Custom-vs-modal presentation?

[Rick Mann]

I have a custom UI view controller presentation using UIPresentationController 
and UIViewControllerTransitioningDelegate. But I'm wondering how best to do 
this only on iPad and iPhone 6 plus, and to use a regular modal presentation on 
other iPhones. Is that even an appropriate desire?

Basically, I show a small details view for my app's objects. But it's big 
enough that it should just fill the screen (and act like a modal presentation) 
on the smaller devices.

Suggestions? Thanks.

Did you try doing an internet search?  This search phrase in Google has a 
number of people asking the same thing with many variations on the same answer:

Re: How to Truncate lines in NSScrollView/NSClipView/NSTextView Combo

[Dave]

Hi,

I’ve tried loads of different way of doing it but none of them work. Maybe its 
because I’m not using Auto-Layout, maybe its just impossible using an 
NSScrollView/NSTextView. In fact, since there isn’t a handy-dandy method or 
property on any of the classes in question to just do it, I’m beginning to 
think that’s the case.

Apple’s documentation is so bad that I can’t find anything related to it and I 
must have wasted around 2 hours fiddling with this. Still I have lots of lovely 
animations in XCode to make up for it so all is not lost! I’m giving up and 
it’s too much of a time-sync to muck around with it as I have more pressing 
things that need doing.

Thanks a lot for for taking the time to help.

All the Best
Dave

Re: How to Truncate lines in NSScrollView/NSClipView/NSTextView Combo

[Bill Cheeseman]

Graham Cox is right.

I realized overnight that I was misinterpreting your question. I happen to be 
working on truncation of text myself, and I was focused on the usual meaning of 
"truncation" in the attributed string context. It means placing three periods 
at the end or in the middle of truncated lines of text.

What you are trying to do, as I now understand it, is to keep the original line 
breaks of the text in place, without "wrapping," even though the text view or 
window is made narrower. In other words, your text view will act like a 
peephole into a bigger page. That is what NSTextContainer is for. I think the 
references I gave to you for text handling in general will lead you to the 
relevant documentation.

From the NSTextContainer reference document:

"The NSTextContainer class defines a region where text is laid out. An 
NSLayoutManager 

 uses NSTextContainer to determine where to break lines, lay out portions of 
text, and so on. An NSTextContainerobject normally defines rectangular regions, 
but you can define exclusion paths inside the text container to create regions 
where text does not flow. You can also subclass to create text containers with 
nonrectangular regions, such as circular regions, regions with holes in them, 
or regions that flow alongside graphics."

Since you're in a very speed-sensitive environment, you will also be interested 
in the paragraph that follows that quoted text, about using threads.
