I’m still struggling to create a single scrollview containing a stack of
textviews.
I created an object called “Subdocument” which has two important readonly
properties:
NSTextView* myView
CGFloat myHeight
myHeight returns myView's frame hight, but never less than 10. The

Hi, I have to draw several lines of text, one by one, to an HTML page.
I get the text from an NSTextView, iterating throught the text lines:
lineRect = [layoutManager lineFragmentRectForGlyphAtIndex:index
effectiveRange:&lineGlyphRange];
index = NSMaxRange(l

I don't think it's odd to want an ongoing single flow of control for specific
parts of the program. Limiting para

Yeah, but that doesn't work for the async mode, where I need a dispatch_async
call to queue A to notify it.
Maybe I'd also need a share
Hi list,
I have a UIWebView inside a UITableViewCell that simply won’t scale the page to
fit on iOS8. I have set it to scale pages to fit in IB and have also tried
setting it in code, but it simply won’t do it.
The UIWebView depicts a JPG image located at a web location.
I had no trouble with

You could use some other signaling
On a related topic from my last post, looking at the equivalent situation but
using GCD instead of runloops, the problem appears to be impossible. That is:
* Code running on dispatch queue A starts some async task that will run on
another queue B, and which will signal completion by using dispat

I thought I understood runloops pretty well, but I'm running into a situation
that's got me stumped. Basically it involves how to wait (block) for a future
message-send that will be queued onto the current runloop.
So I've started an asynchronous task that runs on a background thread. When the

Once your application is in the background it becomes fair game for being
terminated. So even if you're using a very reasonable mount of RAM, if you're
in the background you can expect that if some other application needs the
memory your application will be terminated.

Ah, yes, like a kid who picks up the binoculars fat-end first, I was looking at
things the wrong way around (how to limit the size instead of getting the size
and doing something with that info).
Why not check the file size before writing? If the file size > your max, then
get the length of the message you are about to write and trim that many chars
from the front of the file before writing.
Or append the message to your file and after writing, check the file size and
trim the surplus
Hi folks
I have an app which needs to save some of its data into a log file. I have the
method set up already for creating and appending the log file. However, I'd
like to limit the file size and initiate a file turn over when it reaches a
certain size. What is the best way to accomplish this?
