I'm trying to open a database that I have in my project inside Resources.
The problem is that it seems that its impossible to find the database file!
I tried with the complete path, and it works, but this is not a good solution.
I would like to now how to open it!
I'm using this code:
db = [FMDatabase databaseWithPath:#"bbdd.sql"];
I don't know how to find the other part of the "actual" path.
Do you have a solution for me?
Thanks!!!!
You need to find the full path of the database in the your resource bundle, something like this :
NSString *databasePath = [[NSBundle mainBundle] pathForResource:#"mySQLiteDatabaseFile" ofType:#"sqlite3"];
There's a complete example in this thread Copying data to the Application Data folder on the iPhone
Get Document directory:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentDirectory = [paths objectAtIndex:0];
NSString *dbPath = [documentDirectory stringByAppendingPathComponent:#"Test.db"];
Next
DB = [FMDatabase databaseWithPath：dbPath];

I am developing one iOS app in that I am using sqlite database.I have inserted records in database now I want to see that records.I searched in Library->Application Support->iPhone simulator, But in iPhone simulator folder nothing is present.So is there any another way to view sqlite database records.
Please help me,
Thank you.
This is my code for file path
-(NSString *)filePath
{
NSString *documentDir=[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0];
return [documentDir stringByAppendingPathComponent:#"Test.sqlite"];
}
Now you can have your Simulator folder as "Core Simulator" not as "iPhone simulator"
Use the following Code.
// Get the Sqlite Data from the url in a NSData Object
NSData *sqlData = [[NSData alloc] initWithContentsOfURL:[
NSURL URLWithString:[sqlUrlStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]];
// Store the Data locally as Sqlite File
NSString *resourceDocPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *filePath = [resourceDocPath
stringByAppendingPathComponent:#"Test.sqlite"];
[sqlData writeToFile:filePath atomically:YES];
NSLog(#"File Path: %#", filePath);
In Console as:
File Path:
/Users/Library/Developer/CoreSimulator/Devices/3C0492CE-2C27-48D8-AB04-7B7EFDB77228/data/Containers/Data/Application/91AF3E65-D0C2-4CC9-A7F6-35DD32AB1FD0/Documents/Test.sqlite
Now You can easily go to your database file path and open it where ever you want.
You can achieve this by using a simple code and opening the Sqlite file in to a simple Sqlite Client like chrome extension(SqliteManager), Firefox Extension and Navicat Premium.
Code:
-(NSString *)GetDocumentDirectory
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
NSString *documentsDir = [paths objectAtIndex:0];
return documentsDir;
}
-(NSString *)getDBPath
{
NSString *documentsDir = [self GetDocumentDirectory];
return [documentsDir stringByAppendingPathComponent:#"YourSqliteFileName.sqlite"];
}
Call it like this
NSString *dbPath = [self getDBPath];
NSLog(#"Database Path = %#",dbPath);
Note: Every time you will run your application on simulator, Every time a new path is created which will be different from your previous path so you have to just copy paste this path and open it in any Sqlite Client.
I am having random error while reading saved photos from document directory in iPhone. I save photos taken from my app to document directory and then read it from there next time when user come back. However, after XCode 6 & base SDK change to 8.1, this document directory path keeps changing. So sometime I found photos and sometime not.
I read few posts online thats says that not Apple differentiate App from Data and that's why this issue coming up. Anyone has any thoughts on this? Any solution?
This is how I save file to document Directory
NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentDirectory = [path firstObject];
NSString *filePath = [documentDirectory stringByAppendingPathComponent:#"key"];
[image writeToFile:path atomically:YES];
And this is how I read it:
NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentDirectory = [path firstObject];
NSString *filePath = [documentDirectory stringByAppendingPathComponent:#"key"];
UIImage *cellImage = [[UIImage alloc] initWithContentsOfFile:filePath];
Go to Product - Scheme - Edit Scheme - Options - Working Directory and specify working directory
I have an app where I need to annotate a pdf. I have been using code from how to edit a PDF in objective-c? and it's great, except the file location part. I was getting the pdf from using
NSString *newFilePath = [[NSBundle mainBundle] pathForResource:#"Untitled_4" ofType:#"pdf"];
This was working in the Simulator, but will not work on my testing iPad.
I was getting this error:
CGDataConsumerCreateWithFilename: failed to open 'long boring file path' for writing: Operation not permitted.
I also played around with
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *newFilePath = [documentsDirectory stringByAppendingPathComponent:#"Untitled_4.pdf"];
I now understand that "You are not allowed to write to the application bundle." Thanks The operation couldn’t be completed. Operation not permitted
When I later try to open the new annotated pdf it does not open correctly.
Any help would be greatly appreciated. You guys rock!
Hopefully this will help everyone else who needs help with pdf annotations in iOS.
Answering my own question.
I ended up using
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *newFilePath = [documentsDirectory stringByAppendingPathComponent:#"Untitled_4.pdf"];
then drawing everything.
The problem was not there, it was getting the finished pdf later to show it. I needed to use that same code later.
Thanks for your help.
Hope anyone confused who finds this later will have their problem solved as well.
I have created some PDF files programatically, which i am storing into the devices memory using the following code >>>>
NSString *fileName = [NSString stringWithFormat:#"SampleTextFile.pdf",strFinalString];
NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *saveDirectory = [path objectAtIndex:0];
NSString *saveFileName = fileName;
NSString *documentPath = [saveDirectory stringByAppendingPathComponent:saveFileName];
I can see the file in the Devices Document folder.
I want to hide these files so that the user can not see or delete it.
Can anyone help me out to do this.
A good place to store private data is in ~/Library/Application Support/, which is the folder used on the Mac for this purpose.
You can generate a path to this folder using:
NSString *appSupportDir = [NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, NSUserDomainMask, YES) firstObject];
You'll have to create the folder yourself the first time you use it, which you can do with:
if (![[NSFileManager defaultManager] fileExistsAtPath:appSupportDir])
{
[[NSFileManager defaultManager] createDirectoryAtPath:appSupportDir withIntermediateDirectories:YES attributes:nil error:NULL];
}
I wrote a simple library that makes this and all other useful iOS folders available as methods on NSFileManager: https://github.com/nicklockwood/StandardPaths
Just prefix the filename with a dot, as in .SampleTextFile.pdf.
But the real solution is to not store the document in the NSDocumentDirectory in the first place. You should create subdirectory in the NSLibraryDirectory and store this stuff there. It also gets backed up and will not get purged like Caches and tmp, but the user cannot access it with iTunes.
I have my code all set up to actually record the files. What I need, though, is a way to see where they are all saved and list them in a UITableView. I'm not asking the the implementation for the table; I only need a way to see where they are all saved.
All your data is saved into your application's document folder. You can access it with:
NSString *documentsDirectory;
NSArray *paths = NSSearchPathForDirectoriesInDomains
(NSDocumentDirectory, NSUserDomainMask, YES);
if ([paths count] > 0) {
documentsDirectory = [paths objectAtIndex:0];
}
Assign an array to get a list of all your recorded files.
Your url where you are going to save the recorded file:
NSURL *urlOfRecordedFile = [NSURL fileURLWithPath:[NSString stringWithFormat:#"5#/recordFile.caf",[[NSBundle mainBundle] resourcePaht]]];
And here is the actual path of you file
NSLog(#"%#",url);
