I am trying to construct a library in IOS.
In my library ,I use a method -(void)loadNewData to load some data EX:test.csv.
But when I export my library and let the other app use my library to excute the loadNewData method.
I found it can not be load correctly. It seems that because there is not such a file test.csv in the app.
How should I revise my code? Or where should I notice when I export the library?
Thank you for watch my question.
And sorry for my poor English.
Here is the a part of code of the loadNewData:
NSString *resourcePath = [[NSBundle mainBundle] resourcePath];
NSString *Rawsurveys=[resourcePath stringByAppendingPathComponent:#"test.csv"];
NSString *RawsurveyResults;
if([[NSFileManager defaultManager]fileExistsAtPath:Rawsurveys])
{
NSLog(#"find file");
NSFileHandle *RawfileHandle=[NSFileHandle fileHandleForReadingAtPath:Rawsurveys];
RawsurveyResults=[[NSString alloc]initWithData:[RawfileHandle availableData] encoding:NSUTF8StringEncoding];
[RawfileHandle closeFile];
}
You could probably create a bundle within your library and add you test.csv there.
Then you can access your test.csv from your own bundle.
Example of how I use images from my bundle. [UIImage imageNamed:#"myBundle.bundle/myImage"]. You could use the somewhat same for your file

I want to get the source code from .m file so I use this way:
NSString *path = [[NSBundle mainBundle] pathForResource:#"ViewController" ofType:#".m"];
NSString *content = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];
NSLog(#"%#", content);
However the console print "null".
I wonder if there any way we can use to get .m file's content even if use private method.
If you're copying the actual source file inside your application's bundle and including it, then sure, that'll work, although I don't know why you'd want to do that.
If you're wondering if you can decompile a binary file back to Objective-C code, then no, you can't do that—at least not simply. If you have good enough skill with assembly language, of course, you can read a disassembly of the code, figure out what the original Objective-C did, and use that knowledge to recreate it.
After I build an app with sqlite. I have installed SQLite manager in Firefox. Doesn´t help because I really don´t know where is that file. I tried many ways.
And finally I try to find this file
_databasePath = [[NSString alloc] initWithString:[docsDir stringByAppendingPathComponent:#"myUsers.db"]];
To open with MesaSQLite
Still have the same problem. Where is my file.
Here is the last way I have used:
/Users/{YOUR NAME}/Library/Developer/CoreSimulator/Devices/{DEVICE ID}/data/Containers/Data/Application/{APPLICATION ID}/
I still can not find it. I have open almost every project folders.
Please help me.
Dont open Library on MacintoshHDD. You need to open Library on your USERName Folder. There,normally library folder is hidden. You need to follow the following to see the hidden files.
Or simply copy paste the path into the search finder on your mac.It will take you directly.
The long way to show hidden Mac OS X files is as follows:
Open Terminal found in Finder > Applications > Utilities.
In Terminal, paste the following:
defaults write com.apple.finder AppleShowAllFiles YES.
Press return.
Hold 'alt' on your keyboard, then right click on the Finder icon in the dock and click Relaunch.
You should be able to find this using this method :
- (NSURL *)applicationDocumentsDirectory
{
NSLog(#"%#",[[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject]);
return [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];
}
Just copy paste whatever is logged in navigate into the folder where you stored your sqlite file
The end result should look like this :
~/Library/Developer/CoreSimulator/Devices/4D2D127A-7103-41B2-872B-2DB891B978A2/data/Containers/Data/Application/0323215C-2B91-47F7-BE81-EB24B4DA7339/Documents/MyApp.sqlite
Please note that the long ID's will obviously be different, as well as the file name.
You just following line of code to Log.
NSString *databasePath = [[NSBundle mainBundle] pathForResource:#"myUsers" ofType:#"db"];
Or use below code.
NSBundle* bundle = [NSBundle bundleWithPath:[[NSBundle mainBundle] pathForResource:#"myUsers" ofType:#"bundle"]];
NSLog(#"%#", bundle);
NSString* test = [bundle pathForResource:#"myUsers" ofType:#"db"];
NSLog(#"%#", test);
NSDictionary* dict = [NSDictionary dictionaryWithContentsOfFile:[bundle pathForResource:#"Root" ofType:#"plist"]];
NSLog(#"%#", dict);
I am using the Core Data Editor a lot for my iOS projects. It is compatible with Mac and iOS applications and support XML, SQLite and binary stores, etc. It is free. :-)

So I'm pretty lost with this one and really new to epub files. I've done a bit of searching but can't seem to put everything together in my head.
My app uses DropBox's Chooser API to get a file from a user's DropBox folder. In this case, I want to open up a .epub file. So when the user chooses a file, the DropBox API gives me back an NSURL object to that file. For example:
https://dl.dropboxusercontent.com/1/view/e8bmxpkree6nc67/The%20Art%20of%20War.epub
And now, I've tried a couple different tools to try to read this file. Originally, I tried using KFEpubKit. But when I called:
epubURL; // The url from DropBox (shown above)
NSURL *documentsURL = [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];
self.epubController = [[KFEpubController alloc] initWithEpubURL:epubURL andDestinationFolder:documentsURL];
self.epubController.delegate = self;
[self.epubController openAsynchronous:YES]
I would get back an error that the file couldn't be unzipped. The error reads as:
Epub Error: Error Domain=KFEpubKitErrorDomain Code=1 "Could not extract epub file." UserInfo=0x170275400 {NSLocalizedDescription=Could not extract epub file.}
I looked into the code and narrowed down the problem a little bit. The KFEpubKit uses the SSZipArchive utility to unzip files. And from this point on, I'm a bit stuck. The [SSZipArchive unzipFileAtPath: toDestination:] call seems to be failing when used with the epubURL.path. I'm not sure if this has something to do with the fact that my file is a .epub extension and not a .zip extension. Or maybe there's some stuff to do after getting the URL from DropBox and before giving it to the KFEpubKit tool?
In the end, I'm expecting to have to display the text of the book with a UIWebView. But I'm just not sure how to handle this .epub file. What should I do with the file from Dropbox? Any help is much appreciated.
A quick glance indicates that that SSZipArchive wants a local file URL, not a remote HTTP URL. Try downloading the file first (NSData with contents of URL, then write to some temp file) then create a file URL that points to the temp file, and send that into the KFEpubController:
// Download the file from dropbox
epubURL; // The url from DropBox (shown above)
NSData * epubData = [NSData dataWithContentsOfURL:epubURL];
NSString * tempPath = [NSTemporaryDirectory() stringByAddingPathComponent:#"temp.epub"];
[epubData writeToFile:tempPath atomically:YES];
NSURL *tempURL = [NSURL URLWithString:tempPath];
NSURL *documentsURL = [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];
self.epubController = [[KFEpubController alloc] initWithEpubURL:tempURL andDestinationFolder:documentsURL];
// etc.
(Coding from memory.) All normal caveats apply here-- you'll want to do proper progress/error handling on the download, get rid of the temp file, etc, etc.
I'm building an application and want to load the cocoapods auto-generated acknowledgements markdown file into an NSString to be displayed in my application. I though it would be as simple, as doing this:
NSString *path = [[NSBundle mainBundle] pathForResource:#"Pods-acknowledgements" ofType:#"markdown"];
NSString *content = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];
But this doesn't work.... Is there a way to access this file?
It doesn't look like this file is automatically copied into your project bundle.
You need to add this file to your Copy bundle Resource build phase. It's also worth nothing that the file name actually contains your project's name Pods-<PROJECT_NAME>-acknowledgements
In practice you may want to make a symbolic link in your project that points to the generated file in the Pods directory to ensure that the newly generated file is used each time
I have tried this in a variety of ways and yet it never pops out my file as a string. Any help would be much appreciated. Perhaps a fresh set of eyes can get it.
static NSString *JSParse;
JSParse = [NSString stringWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"nameFinder" ofType:#"js" ] encoding:NSUTF8StringEncoding ];
NSString *filepath = [[NSBundle mainBundle] pathForResource:#"nameFinder" ofType:#"js"];
NSLog(filepath);
if (filepath)
{
NSString *someJscript = [NSString stringWithContentsOfFile:filepath];
NSLog(someJscript);
}
NSLog(#"StartParse");
NSLog(JSParse);
NSLog(#"End Parse");
The end goal is to use javascript to parse HTML from a website that isn't mine and yes it sucks. (Parsing although my code is suspect too at this point);

You don't need to change your .js to .txt if you use this method.
The Reason for this has something to do with it being a JS file extension. Changing it to a txt file invariably fixes the problem. I'm not sure why this is so but i'm assuming it's some compilation issues.
