Re: Constraining window width to scrolling contents with autolayout

2015-05-25 Thread Jonathan Hull 
I believe this is where the constraint priorities come in.  The window size 
will be affected by constraints with priorities larger than 500 and may 
override constraints under 500.  Also, when dealing with ScrollViews it can get 
a bit tricky, so it helps to add a single view inside the scrollView which you 
can apply constraints against and then add your contents to that view.

In this case you would add an inequality constraint between that view in the 
scrollView and the window’s main view (i.e. the window width must be 
less-than-or-equal to the scrollView’s content plus some constant). You might 
need to write that programmatically (as opposed to in IB).

(Note: This is off the top of my head, haven’t gotten a chance to test it)

Thanks,
Jon

10.10 replacement for SMJobCopyDictionary

How to translate this into 10.10 without deprecation warnings?

CFDictionaryRef diref = SMJobCopyDictionary( kSMDomainSystemLaunchd, 
“de.mdenkmann.MyTool” );

The point of launchd is to start jobs on-demand. Why are you trying to
check if your launchd job is already running? What's to say that as soon
as launchd tells you it's running, it doesn't turn around and kill it
because its sudden termination suspension count dropped to 0?

Re: Copy test docs to Simulator App's Documents folder?

2015-05-25 Thread Michael David Crawford 
I'm still trying to load the simulator with some sample files for my
app's Documents folder.

I'm able to put documents in the Documents folder for my app on my
iPad.  I can use the Devices window to copy my .xcappdata folder to my
project heirarchy.  I can select it to be added to my simulated app in
the Edit Scheme / Options dialog.

The .xcappdata folder does contain the desired documents but they
don't show up in my app's UI.  Is this a known bug in Xcode or the
Simulator?

There is some possibility it is a bug in my code.  I'll look into that
while I eagerly await your response.

Thanks for the bug report. If your workarounds look relevant to the bug then 
please describe them there. If the behavior differs or does not differ in debug 
vs release builds please mention that too.

You can also use the Allocations instrument to record and display allocation 
and retain/release history of individual objects. It should work fine alongside 
Guard Malloc.

Do you have an OpenRadar for it? Sounds like a fascinating bug.
