A Google-Maps like single-finger zoom gesture for the ArcGIS Runtime SDK for iOS. Awesome idea, Google Maps team! 👏👏👏

This article was originally written for objc.io issue 12, but didn't make the cut. It was intended to be read in the context of the other articles, so if you aren't familiar with concepts such as CALayer property animations and the role of actionForKey:, read the articles in that issue first.

Hacking UIView animation blocks for fun and profit

In this article, I'm going to explore a way that we can create views that implement custom Core Animation property animations in a natural way.

As we know, layers in iOS come in two flavours: Backing layers and hosted layers. The only difference between them is that the view acts as the layer delegate for its backing layer, but not for any hosted sublayers.

In order to implement the UIView transactional animation blocks, UIView disables all animations by default and then re-enables them individually as required. It does this using the actionForLayer:forKey: method.

Somewhat strangely, UIView doesn't enable animations for every property that CALayer does by default. A notable example is the layer.contents property, which is animatable by default for a hosted layer, but cannot be animated using a UIView animation block.

Created October 7, 2013 21:05
Objective-C code to fit a CGRect inside or outside another CGRect while maintaining aspect ratio. The fitted rectangle is centered on the target rectangle.
CGFloat ScaleToAspectFitRectInRect(CGRect rfit, CGRect rtarget)
{
// first try to match width
CGFloat s = CGRectGetWidth(rtarget) / CGRectGetWidth(rfit);
// if we scale the height to make the widths equal, does it still fit?
if (CGRectGetHeight(rfit) * s <= CGRectGetHeight(rtarget)) {
return s;
}
// no, match height instead
return CGRectGetHeight(rtarget) / CGRectGetHeight(rfit);

Auto-increment your Xcode project's build number
# This script will auto-increment your Xcode project's build number for every build (debug & release).
# It will also increment the third position of a semantic formatted version string only for release builds
#
# Examples:
# Buil number (CFBundleVersion): from 1.2.1235 to 1.2.1236
# Version string (CFBundleShortVersionString): from 1.2.5 to 1.2.6
#
# 1. Select your Target in Xcode
# 2. Select "Build Phases" Tab
# 3. Select "Add Build Phase" -> "Add Run Script"
