I am trying to read entire .m file in a string using code:
NSString* fullFileName = #"file.m";
NSString* fileName = [[fullFileName lastPathComponent] stringByDeletingPathExtension];
NSString* extension = [fullFileName pathExtension];
NSString* filePath =[[NSBundle mainBundle] pathForResource:fileName ofType:extension];
NSString* fileTextContent=[NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:NULL];
But it returns null.
Is it possible to read .m file from bundle in a string in iOS?
It's possible, but you should make sure the .m file is in the bundle first (they aren't by default).
Right click on the app under the products folder in Xcode, select "Reveal in Finder", then right click on the app in finder and select "Show Package contents" to see what's in the bundle.
If you need to add it, you can do that under the project settings in xcode > build phases > copy files phase.
Including .m files in the bundle would be somewhat strange though. There's almost certainly a better way to do whatever it is you're trying to do. Maybe if you went into more detail on what that is, people could suggest them.

I've been using localization in my app, but for some reason, some of the strings (not all of them) won't translate, I see the key instead the value. I've tried to check if the app finds the localization files by doing this:
NSString *enPath = [[NSBundle mainBundle] pathForResource:#"en" ofType:#"lproj"];
NSString *hePath = [[NSBundle mainBundle] pathForResource:#"he" ofType:#"lproj"];
NSString *ruPath = [[NSBundle mainBundle] pathForResource:#"ru" ofType:#"lproj"];
NSString *esPath = [[NSBundle mainBundle] pathForResource:#"es" ofType:#"lproj"];
NSString *frPath = [[NSBundle mainBundle] pathForResource:#"fr" ofType:#"lproj"];
NSString *arPath = [[NSBundle mainBundle] pathForResource:#"ar" ofType:#"lproj"];
And none of them is nil.
I've checked the name of the localization file and it's Localizable.strings as it should be.
Also checked if the key exists inside the Localizable.strings files and it does.
I've also tried:
Empty Cache
Cleaning all targets
Delete Derived Data folder
Restart
Reset simulator
Convert to UTF-16
Remove all localization files and recreate them.
Also tried to do everything that is in this question.
It's important to say that this is not just a Simulator/Cache problem. It's also showing on devices which download the app. (I have Enterprise account).
What more can I do in order to identify nor fix the problem?
So I found the problem, I guess who translated the Localizable.strings files for me is an asshole. In 4 places in my strings file there was a row as followed:
"KEY" ;= "Value"
This line cause some kind of a crash, but let the compiler to build successfully for some reason. That's why I couldn't find the bug, only when I decided to take the last Key and Value which are not translate and move them to the top of the Localizable.strings file. Then I was able to understand and see that the problem is somewhere in the middle of the file and the top Keys and Values are translated fine.
One thing that you can do catch these kind of errors is to make a copy of the strings file, change the extension to plist and try to open it in Xcode. If there is any problem in the strings file it will show in Xcode since the dictionary will contain only the keys till the point where there is an error. You can then do a Find operation and find the error until you are sure that all strings appear in the plist file. You can then rename the file back to .strings
If you specify table:nil, then NSBundle will try to fetch the localization from the default table (the one in SOMELANG.lproj/Localizable.strings). If you have the localization elsewhere, you should explicitly specify the table using table:#"File" (or use the NSLocalizedStringFromTable() macro in a similar manner:
NSString *value = NSLocalizedStringFromTable(#"key", #"File", nil);
Also,
Double check that the Localizable.strings file is being added to
Targets -> BuildPhases -> Copy Bundle Resources
It hadn't been added automatically for me.
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. :-)

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
Problem : [NSBundle mainBundle] pathForResource returns null (0x0)
I read a lot of posts on this topic, here is what I found:
Make sure the file you are trying to get a path to, is in the project. To check, look in the project file list for the file, if it is not there, drag and drop it in.
Check that the file your trying to load is being copied to the app. To do this, click on project under project files (blue bar with project name in it->Click on the target->Click on Build Phases->Click to expand the "copy Bundle Resources", and make sure your file is in it. If it is not, click the plus, and add it.
Make sure the case matches exactly. (aka - The simulator will work/the app will not problem) Make sure the case matches exactly, otherwise it will return nothing. To fix this, just rename it in the project, or use the right case in the source.
Project may be missing the media framework. To fix this click on your project menu -> click on the target -> click to expand "Link Binary With Libraries". Now select MediaPlayer.framework and build the code.
If all else fails, clean the project, and try again.
All this is checked/fixed, but not working. I had this working fine, and then I changed the video that I am showing in the app. Since i changed the file, it stopped working.
NSString *path = [[NSBundle mainBundle] pathForResource:#"multiplying" ofType:#"m4v"];
Q: why is it null? The file is case matched/typed correctly and is about 10 megs. (is the file too large?) Works fine in the simulator, and I can get the path to an image, a line above this one, with no error.
You say it's working in simulator and not working on device?
May be you should try to copy the file at first launch to one of the application sandbox folders and access it like this:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *pathForTheFile= [documentsDirectory stringByAppendingPathComponent: #"multiplying.m4v"];
I'm trying to load a plist file in my application with
NSBundle* bundle = [NSBundle mainBundle];
NSString* plistPath = [bundle pathForResource:#"CategoryData" ofType:#"plist"];
categoryProps = [[NSArray alloc] initWithContentsOfFile:plistPath];
but the categoryProps array always ends up with 0 objects. I've placed the CategoryData.plist file under the "Supporting Files" dir in my project but I can't figure out how files are arranged in the compiled app.
Can someone point me to docs that describe how the file system of an app is laid out and how to figure out where files are located within the file system?
I forgot to point out that I am using XCode 4 which does not create a resources folder for the project
Your loading code code should work for locating the file within the file system. In a project, I have:
NSString *data = [[NSBundle mainBundle] pathForResource:#"data" ofType:#"plist"];
What I would do is log the plistPath to the console or inspect it in the debugger, then navigate to that location on disk and determine if the plist ends up where you think it does.
Also, locate your application bundle in /Users/<# Username #>/Library/Developer/Xcode/DerivedData/<# Unique Appname #>/Build/Products/Debug-iphonesimulator/<# Appname #>.app, right click on it and select "Show package Contents". Ensure that you see your plist where you think you should.
You need to place your plist file in the Resources folder. Then you will be able to load and use them like this
NSString *path = [[NSBundle mainBundle] bundlePath];
NSString *finalPath = [path stringByAppendingPathComponent:#"Info.plist"];
NSDictionary *plistData = [[NSDictionary dictionaryWithContentsOfFile:finalPath] retain];
UPD: In xcode4 you must to place plist files in the "Supporting Files" directory instead of "Resources". And try to use NSDictionary instead of NSArray
