问题 I am making a REALLY BASIC UITableView project without any data source. I am just displaying "1" on first and only cell.

On initial load, I get this: SomeShit[27511:936083] number of sections SomeShit[27511:936083] number of rows in section SomeShit[27511:936083] number of sections SomeShit[27511:936083] number of rows in

问题 Long time reader, first time poster. I use automatic cell height with auto layout in my app. In iOS 8.3 and 8.4, this appears to be broken. I have a sample project. When built in 8.2 or lower, it works properly. The cell heights are determined by Autolayout. When built in 8.3 or 8.4 it doesn't work. I have searched online and I don't see anyone posting about this issue. Take a look at the screenshots below. Any help is appreciated. Cell Height Project ZIP Screenshot comparison http://jeffburg

问题 Apple recently added support for indexeddb in both iOS8 Safari and Safari 7.1 on OSX. I am attempting to use this in a web application that stores about 65,000 records in indexeddb and queries them using some compound indexes. It's working for me, but compared to Chrome's implementation of indexeddb, it's really, really slow.
