The first of its kind, DPM provides decision support for each stage of the performance problem lifecycle DPM DPM is an innovative platform for IT production database performance management.This part of the old app still compiles and works under iOS 13 and Xcode 11: I still use the app regularly, but have added Swift modules over the years and recently implemented some SwiftUI views. Note the conversion of the path to UTF-8. If you use it, you might want to change the sqlite3_open to READONLY not READWRITE. Here's my database opning code from an old app - plus the copy to Documents code. It's a long time since I've used Objective C with SQLite, but I have a vague recollection of a similar problem to yours. Personally, I don't like having production databases in the bundle, only as the initial state (usually just for the schema). In the long term, it would still be advisable for him to sort out the copying from bundle issue: necessary if the app is for general distribution. Adding the database file to Documents via iTunes will ensure that it's there and valid. Turning on iTunes file sharing will allow him to confirm that a) the database is in Documents (i.e if the copy has indeed worked) and b) that the contents are not corrupted (provided he re-exports and examines, or the file size is correct). Without seeing the copy code (where and when in the app startup) and the SQLite error it's hard to tell what's going wrong. His problem appears to be that the copy to Documents is unsuccessful on the physical device, or SQLite objects to opening the database there. This is a valid approach, except that jgm has set his app up to use the Documents directory ( an acceptable location for app data) and he's a newbie. If you are doing a lot of database work, then getting a Mac-based browser is well worth it. I use RazorSQL, but there are free Mac versions such as "DB Browser for SQLite". NOTE that you can also Save your database file from your device, via iTunes, to your Mac, and then examine the database on your Mac if you have appropriate SQLite reader software. Your database file will (should) now be in the correct location for use by your app. Select your database file from your Mac's storage and press the blue Add button, then press the blue Done button.Ĩ. Scroll to the bottom of the panel at right to show the "Add" button and then click it.ħ. You should then see your app listed, so click on it.Ħ. You should then see a list of options on the left of screen: click File Sharing.ĥ. With the device connected to your Mac, open iTunes and click the small device icon near the top left of screen. The Type property should be Boolean and the Value "YES"Ĥ. Press the + button that is to the right of the first line "Information Property List" and then, in the box that appears, type "Application supports iTunes file sharing". In Xcode's Project Navigator (View > Navigators > Show Project Navigator) at the left of screen, click on istĢ. Please, some help or advice, I would appreciate it. I'm going crazy looking for possible solutions on the internet, but none works for me and I've been standing for 3 months trying to run the application on the iphone. I don't know if what I am doing is correct or there is another way to do it. Because the previous code gives me a route on the iphone, and I try to put the sqlite database there but it does not run, the application is blocked because it cannot find the database, even if I put it there. The problem is when I connect my iphone and try to run the application. NSString *dbPath = [documentsDir route is - I get the path, and copy the sqlite database, so the application works perfectly in xcode. Sqlite3 *bd NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) I have the following code to know where I have to put the database. I run the application in xcode, with the simulator. An application that has a sqlite database.
