d-ronnqvist / Thoughts on removedOnCompletion in SparkRecordingCircle.md
Last active May 16, 2020 02:51
What I think is wrong with the Spark Recording Circle code and why

There was [a tweet][tweetSoto] a couple of days ago that resulted in a discussion/question about what it wrong with the usage of removedOnCompletion = NO in the [SparkRecordingCircle code][code] for that [Subjective-C post][post].

We all kept saying that the explanation doesn't fit in a tweet, so here is my rough explanation about the issues.

But, let me first say that I think that the Subjective-C articles are reallt cool and useful to learn from. This is trying to reason about the general usage of removedOnCompletion = NO, using that code as an example, since that was what was discussed on twitter.

The root problem, as [Nacho Soto pointed out][rootProblem], is that removedOnCompletion = NO in combination with fillMode = kCAFillModeForwards is almost always used when you are not updating the model layer. This means that after the animation has finished, what you see on screen is not reflected in the property of the layer. The biggest issue that this can cause is that all the

Simple solution that allows to block the parent layoutSubview-triggering, see https://gist.github.com/steipete/9723421. In short, changing a frame of a subview outside of layoutSubviews will trigger the parent's layoutSubviews. Sometimes this is not what we want, especially when you consider performance. In my case (http://pspdfkit.com) this was…
@interface UIView (PSPDFKitAdditions)
// Allows to change frame/bounds without triggering `layoutSubviews` on the parent.
// Not needed for changes that are performed within `layoutSubviews`.
- (void)pspdf_performWithoutTriggeringSetNeedsLayout:(dispatch_block_t)block;

[PSPDFHUDView updatePageLabelFrameAnimated:] resizes a label that is inside PSPDFHUDView by calling sizeToFit. This triggers layoutSubviews on PSPDFHUDView. That's something I would like to prevent. What could I do here? Followup: https://gist.github.com/steipete/9725247

Reciprocal Needs in the Employment Relation

We can look at two sides of the management coin: What do the individuals get out of it? And what benefit does the whole system derive from it?

I will disregard any benefits that accrue to managers just by holding the position of managing. Those are just circular logic. Circular logic abounds in discussions of management and hierarchy. For example, consider status reports. It will be said that status reports are necessary so managers know what their employees are working on. It’s

Declare on your main init that all other init methods should call. It's a nice additional semantic warning. Works with Xcode 5.1 and above. Not tested with earlier variants, but should just be ignored. A reference to this macro shortly appeared in https://developer.apple.com/library/ios/releasenotes/ObjectiveC/ModernizationObjC/AdoptingModernObj…
