问题 I have an app that was developed in iOS 6. But now in iOS 7 or even my app compiled for iOS 6, but running on an iOS 7 device the top navigation bar (the new giant one in iOS 7) my content is hidden. The top navigation bar covers it. If I manually move it down with CGRect it looks good in iOS 7, but now iOS 6 looks horrible (to much space above it). The app was built with autolayout off because autolayout is way to difficult to get things setup correctly. My question is, is there an easy way

问题 With WAL (Write-Ahead-Logging) enabled in SQLite 3.7 (which is the default for Core Data on iOS 7), how do I merge/commit the content from the -wal file back into the main database file? 回答1: Do a checkpoint, i.e., execute PRAGMA wal_checkpoint. 回答2: From the command line, do this: sqlite3 MyDatabase.sqlite VACUUM; CTRL-D to exit the sqlite console. Done! The -wal file should now have a size of 0 and everything should be in your main database file. 来源： https://stackoverflow.com/questions
