![]() I started the Simulator and logged into my iCloud account. Once I was done with that I sat back down to work on the sync project. I used some superglue and, later, Bondo and found a dubious solution. The result is that the glovebox closes awkwardly. I didn't notice for months as we hardly open it. When Curry Honda did some recall repairs for the airbags, they didn't attach the pneumatic latch and the plastic hinge cracked. The iCloud debug gauge continually reported a status of Disabled, so clearly something was amiss.Īfter several hours of playing with provisioning profiles and resetting my iCloud documents and data for the test app, I took a break and started trying to fix the latch on our Accord's glovebox. I ran into some issues and couldn't get anything to sync. Today I set up a simple project to test iCloud with Core Data sync (the last time I worked with iCloud+CoreData was back in iOS 5, and I wasted months an indie developer can't afford to waste). ![]() In simplified terms, the min- and max-y offsets are: min-y: -top ![]() If the effective excess is greater than or equal to zero, some scrolling is necessary to get to the bottom: that amount is just the excess. If this is negative, everything is visible and the max-y offset is the same as the min-y offset. ![]() The effective content excess is then top + (content - visible) + bottom. Factor in any top or bottom insets by thinking of them as additional regions hugging the top and bottom of the content. If excess is less than zero, it means the content is already visible. With that in mind, consider the amount of content beyond the visible bounds as: excess = content - visible. If your content extends 5pts beyond the bottom of the screen, you'd expect to have to scroll 5pts in order to make it visible. The maxmimum offset is the amount you'd need to scroll in order to just see the bottom of the content. Whether you have a small or large amount of content, the min-y offset is 0 - top. If a top inset is applied, this has the effect of permitting additional scrolling up past the minimum, not to exceed the top inset amount. The minimum content offset is typically 0, which makes sense. I should have gone back to the docs to confirm my understanding. My problem was due to conceptually applying the bottom inset at some point beyond the bottom of the frame even when the content size was much less than the bounds size. Next, keep in mind the essence of the scroll view: The scroll view must know the size of the content view so it knows when to stop scrolling by default, it “bounces” back when scrolling exceeds the bounds of the content.įinally, remember what the contentInset does: Use this property to add to the scrolling area around the content. By default, the origin of the bounds rectangle is set to (0, 0) but you can change this value to display different portions of the view. On the screen, the bounds rectangle represents the same visible portion of the view as its frame rectangle. In fact, the documentation for UIView mentions adjusting the bounds origin as a way to display a different area of a view. The scroll view bounds and contentOffset are related: setting the content offset is same as adjusting the bounds.origin. Some key things to remember when dealing with UIScrollView: It took me too long to figure it out, partly due to a misunderstanding of what the contentInset means. I started sketching out various configurations of content within a scroll view, considering content insets and situations with less than or more than a full screen of content. The issue was even more pronounced when a non-zero bottom inset was applied to the scroll view. During testing I realized I've had a bug in this code for several years: my max offset calculation was incorrect. I've supported this feature in Taskboard's project view for a while, so I copied that code into my new app. This came into play while working on a feature that automatically scrolls off-screen content into view when an item is dragged to the top or bottom of the scroll view.
