I'm getting NSURLErrorNotConnectedToInternet when I try to use a v6 IP address as the hostname of NSURLRequest.URL, I assume because the network has no IPv6 connectivity. However, the IPv6 address is just a mapped IPv4 address (e.g. ::ffff:10.0.0.1), and it seems NSURLConnection is being too smart for its own good because regular sockets handle the same address just fine. Is there anything I can do, save for unwrapping the address back into an IPv4 address?

Why am I using NSURLConnection instead of NSURLSession? super-old critical code I won't touch unless absolutely necessary

Why an IP address as the HTTP hostname? Because NSURLConnection either doesn't support DNS failover or its implementation is far too slow for our standards, and there is no way to replace the resolver used by NSURLConnection. I doubt NSURLSession would help because even Safari fails to connect when the "wrong" node is down. Don't worry! I set the Host header manually and I replace the IP address with the hostname in the SSL policy ()

Why an IPv4 address mapped to IPv6? Because I'm adding IPv6 support and it would be simpler if everything was IPv6 all the time

Just a quick check: are you enclosing the address in brackets like the RFC says?

Same effect, only difference is when I don't put it in brackets, the colons are percent-encoded. Apart from that, same exact behavior

So is it not possible to have a universal app where one device idiom 'requires full screen' but the other doesn't?

My fellow project developer is having an issue with TestFlight. He just uploaded a version "1.0.20 build 1" to the App Store, our first public release. This release is free, with some features disabled. Unlike the TestFlight version, this one supports down to iOS 6.1.

So, herein lies a new problem: it obliterated the beta release. Even pushing a "1.0.20 build 2" to TestFlight does not appear for testers.

If this iOS 6.1 thing becomes a point of contention, we'll need to switch to another beta release platform. Perhaps Crashlytics...

Usually this is because you previously added a reference to an item that you didn't want copied, and we remember the state of the check box from one addition to the next.

The most ridiculous App Store rejection yet:

And the screenshot is... the About screen of the application. The external mechanism for purchases is the link to our website I guess? Or maybe the "send logs" button. Meanwhile the nearly identical sister application was approved

This is basically why none of my new side projects are iOS apps anymore. It's just not worth dealing with the review process, never mind the debate of "do I release a new update and wipe out all of my reviews?" Web apps are so much more pleasant (not that the web doesn't have its own obnoxious stuff).

Given what's happening with app review times lately, it's my hope that WWDC is going to seriously overhaul the process. Review times are like 1-2 days now instead of the 7-10 they always used to be. Good stuff, though the whole process is still not how releasing software work in 2016.

@DocBlock @eschaton no, the problem is when you drag a folder of items into some folder reference (group? who cares) that has Xcode-y problems. So even when you Copy Items, and even when the items do copy (checked in Finder), the references are all red / missing.

I mean you can copy them to the folder in Finder, add them to Xcode and not 'Copy items' and that works. But the word 'works' is kind of misleading in that sentence.

The problem was ~~the original 'Images' folder wasn't there, and had to be recreated~~ Xcode.

All I want to do is render text with a stroke that's outside the text, with no fill. The normal way of getting an "outside" stroke of drawing the stroke and then fill over top obviously can't be used (because there's no fill), so the stroke is the equivalent of using "Centered" mode in whatever drawing program you prefer, and looks lovely.

I thought reversing the glyph path and then setting that as the clipping path would work (since StackOverflow says that's how you get an outside stroke on non-text paths), but nope.

Gonna have to rethink this. I've got a ton of glyphs to draw all over the place. Maybe I can add them all to one path, then use that to make an image for use as a clipping mask...

Was able to get the effect that I want. No matter how large the stroke width is, it never draws "inside" the characters, even when fill isn't rendered:

In this image the stroke width has been set to something comically huge as a test.

Instead of messing around with reversing paths etc., I just add all the glyph paths to one big CGPath, draw that as fill in an alpha mask, use the alpha mask as a clip mask in the main CGContext, and then draw the big CGPath with the requested stroke width in the main CGContext.

I know... you'd have to convert the list of points into an array using CGPathApply, and then reverse the array. There's some helpful code I found here, though I didn't use it since I took an entirely different approach to my problem that wasn't based on the path's points.

# ? May 17, 2016 16:20

Yeah, that's what I did, but it still didn't work for my purposes. Wound up using a clipping mask instead of a clipping path instead (see my previous post).

I'm trying to do the following

code:

@interface Helper : NSObject 

@property (weak,readonly, nonatomic) UIView* parent;

@end

@implementation Helper
-(void)setParent:(UIView * _Nullable)parent
{
  if( _parent )
  {
    NSLog(@"removing watchers from parent");
    [self.parent removeObserver:self forKeyPath:@"iconUrl"];
    [self.parent removeObserver:self forKeyPath:@"iconData"];
  }
  _parent = parent;
  if( _parent )
  {
    NSLog(@"adding watchers from parent");
    // watch parent IconUrl change
    [self.parent addObserver:self forKeyPath:@"iconUrl" options:nil context:nil];
    [self.parent addObserver:self forKeyPath:@"iconData" options:nil context:nil];
  }
}
@end

But am running into issues since my parent only gets set to nil after it has been dealloced and the dealloc is failing since I still have watchers attached to the parent. Is there any way to use observers with weak references?

In this case the parent has a reference to to the helper so I have a retain cycle I was trying to fix.

The odd thing is I have one class using the Helper class without any issues and another one is throwing a NSInternalInconsistencyException on dealloc. The usage is the same so I'm not sure what's going on there.

Weak reference don't magically call associated property setters when they get cleared; that's just not how the technology works.

Yeah I've figured that out. My code that was there to remove the observer was never getting called. The odd thing is that in one case the objects were able to be dealloced without any issue and in another case an exception is thrown. The usage is identical so the behavior is a mystery at this point.

One odd thing I'm noticing - if I step through dealloc on my Helper class the debugger has a valid value for _parent but printing _parent or any code that checks for parent against nil determines that it's nil.

I'm wondering if I should forgo KVO and just roll my own since I'm in control of all the classes that are in use.

You can use associated objects to automatically unregister KVO observers on dealloc, but...

this is nearly always the correct choice. KVO can be useful when you don't control the object being observed, but implementing your own form of change notifications when you do is nearly always going to be far better.

This is really just a debugger bug: the debugger ignores the fact that it's a __weak reference, so it just reports the underlying memory contents, which aren't necessarily immediately nil'ed out when dealloc starts.

Agreeing with this.

While not directly a 1:1 with KVO, I love the willSet and didSet in Swift. Most of the time that provides the capabilities that I would have previously used KVO for.

ManicJason: Oct 27, 2003; He doesn't really stop the puck, but he scares the hell out of the other team.

Where is the magical new location that Xcode is storing some fuckery that is not DerivedData? I used to always run into a problem where it would refuse to archive if I switched targets to a target with a different bundle ID (provisioning profile bundle ID does not match bundle ID.) I could always fix the problem by blowing away DerivedData. That no longer works.

edit/fixed: Xcode automagically put the wrong bundle ID in my project settings for some reason, even though the Info.plist was correct. Brilliant.

I was really proud long ago when I figured out how to implement KVO. Now I'm systematically removing it wherever possible because if I see another 'deallocated while observers were still watching' crash I'm going to kill myself.
