can't read plist from resources - iphone

in my resources directory i have a file called lsf.plist
i want to load this file (dictionary) but i always get null as content of the file. i am using the following code. i've verified that the file is in the app after the build.
self.path = [[NSBundle mainBundle] pathForResource:#"lsf" ofType:#"plist"];
NSLog(self.path);
self.lsf = [NSMutableArray arrayWithContentsOfFile:path];
NSLog(#"%#",lsf);
The first log-output shows the path and the second one gives me null....
it would be great if you can help me to solve this issue!
Br,

Is root of your plist array or dictionary?
Also you dont need to use self.
Heres an example from a project of mine:
NSString* path = [[NSBundle mainBundle] pathForResource:#"property" ofType:#"plist"];
NSDictionary *newDict = [NSDictionary dictionaryWithContentsOfFile:path];

Access .plist Values

I am building an app that has a pickerview, thus, I had created a .plist file to make the keys and values. The only issue is I want to be able to access the .plist values. The thing is, the values are name strings which when selected on the picker view i would like to create an if statement where i call a mobile number. I need guide on access the values if that is possible
Any idea on how to carry this out?
NSString *pathToFile = [[NSBundle mainBundle] pathForResource:#"myList" ofType:#"plist"];
NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:pathToFile];
NSString *path = [[NSBundle mainBundle] pathForResource: // here data is file nale of plist
#"data" ofType:#"plist"];
// Build the dictionary from the plist
NSDictionary *dictionary = [[NSDictionary alloc] initWithContentsOfFile:path];

Add & Remove Array Items inside a plist

I have problem with adding and removing items in an array inside a plist file in XCODE.
I'm able to read the array by following code:
// Path to the plist (in the application bundle) ------>>>>>
NSString *path = [[NSBundle mainBundle] pathForResource:
#"Fav" ofType:#"plist"];
// Build the array from the plist ------>>>
NSDictionary *favs = [[NSMutableDictionary alloc] initWithContentsOfFile: path];
Resepies = [favs objectForKey:#"Root"];
And this my plist structure
The senario is to let the user add and remove specific item from the array at a time.
try this code -
NSString *path = [[NSBundle mainBundle] pathForResource: #"Fav" ofType:#"plist"];
// Build the array from the plist ------>>>
NSDictionary *favs = [[NSMutableDictionary alloc] initWithContentsOfFile: path];
Resepies = [favs objectForKey:#"Root"];
[Resepies addObject:addYourObjectHere];
//then add this array into dictonary ;
[favs setObject:Resepies forKey:#"Root"];
// now write dictionary to plist
[favs writeToFile:yourPlistName atomically:YES];
You can't modify files in the application bundle, which is what your code above is attempting to do.
If the file is supposed to be modifiable, you need to move it into the documents folder first (say, on first run) and then read / write to that one subsequently. There are plenty of questions dealing with how to do this, for example : create plist and copying plist to document directory

Get name of Xcode Project in actual code

So you know the part of the project that is "MyNameGoesHere.app" or "MyNameGoesHere.xcodeproj" - is there a way to get the MyNameGoesHere part via objective-c code?
I can get all kind of device info from UIDevice messages but I can't figure out how to get project/app name.
CFBundleDisplayName doesn't work anymore. Use:
NSString *bundleName = [[NSBundle mainBundle]
objectForInfoDictionaryKey:#"CFBundleName"];
You're probably looking at the bundle's InfoDictionary. You can get the app's name via the following code:
NSDictionary *info = [[NSBundle mainBundle] infoDictionary];
NSString *bundleName = [NSString stringWithFormat:#"%#", [info objectForKey:#"CFBundleDisplayName"]];

How to create a NSMutableDictionary using dictionaryWithContentsOfFile: method

I want create and return a dictionary using the keys and values found in a file specified by a given path. I have my file on my Desktop:ciudades.txt (a human readable file!!! no a xml, just for practice). What method of my NSString i need to use and how? Please can somebody help me filling on my code the XXXXXXX. Thanks in advance
- (NSMutableDictionary)ciudades
{
if (!ciudades) {
NSString *path = [NSString XXXXXXXXX];
ciudades = [NSMutableDictionary dictionaryWithContentsOfFile:path];
}
Define a function.
-(NSMutableDictionary*) ReadFileAsDictionaryForPath:(NSString* ) path
{
return [NSMutableDictionary dictionaryWithContentsOfFile:path];
}
Use it as below
NSString *path = [[NSBundle mainBundle] pathForResource:#"MyFile" ofType:#"txt"];
NSMutableDictionary* myDictionary = [self ReadFileAsDictionaryForPath:path];
if(!myDictionary)
{
NSLog(#"Error while reading data from file at path:%#",path);
}
First add that file to your application bundle By adding a existing file from xcode to your project. Then use this method to get the file path for example I'm getting a image's path.
NSString *path = [[NSBundle mainBundle] pathForResource:imageName ofType:#"png"];
then try the dictionaryWithContentsOfFile method and see if it works or not.

Can't read from plist

I have a plist with an array at top level and then a number of items within it.
When I try the following
NSString *path = [[NSBundle mainBundle] bundlePath];
NSString *finalPath = [path stringByAppendingPathComponent:#"Spots.plist"];
spotsArray = [[NSMutableArray arrayWithContentsOfFile:finalPath] retain];
the array spotsArray is empty.
I have tried a number of things and have used plists successfully before. I dont know what the issue is now.
What could be causing the issue, my plist looks like this
It's not an array at the top level it's a dictionary with a single item called 'New Item'.
Try NSMutableArray *mutableArray = [[[NSDictionary dictionaryWithContentsOfFile:finalPath] objectForKey:#"New Item"] mutableCopy] autorelease]
This should mean that your .plist file does not exist or not readable.
Try to create the file with writeToFile at the same path to verify it works. (It can also help you to verify the directory)
