Question

I have such problem: I have a plist file, which I made by adding it to recourse files from anothe project, now I can read it, but I don’t now how to change it. Help me if you can, please.

We cannot directly write to our application bundle, so we need to copy our plist to our application’s document directory for this use:

NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"yourPlistName.plist"];

NSFileManager *fileManager = [NSFileManager defaultManager];

if (![fileManager fileExistsAtPath: path])
{
     NSString *bundle = [[NSBundle mainBundle] pathForResource:@”yourPlistName” ofType:@”plist”];

     [fileManager copyItemAtPath:bundle toPath: path error:&error];
}

Then for editing the plist use:

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *plistPath = [documentsDirectory stringByAppendingPathComponent:@"yourPlistName.plist"];
    NSFileManager *fileManager = [NSFileManager defaultManager];

if ([fileManager fileExistsAtPath: plistPath ]) 
{
    NSMutableDictionary* infoDict = [NSMutableDictionary dictionaryWithContentsOfFile:plistPath];
    [infoDict setObject:[NSNumber numberWithBool:hidden] forKey:@"yourKey"];
    [infoDict writeToFile:plistPath atomically:YES];
}

Here yourPlistName.plist is your plist and yourKey is the key for which you are setting a new value.
