Problem in write on plist

Question

I am writing some data(string) to a plist like this:

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

NSFileManager *fileManager = [NSFileManager defaultManager];
if(![fileManager fileExistsAtPath:pathProduct])
    {
    NSString *bundlePath=[[NSBundle mainBundle] pathForResource:@"unicurd" ofType:@"plist"];
        [fileManager copyItemAtPath:bundlePath toPath:pathProduct error:&error];

    }


    NSString *recipiBookMark= pageURL;

    NSMutableDictionary *recipieBM = [[NSMutableDictionary alloc] init];
    [recipieBM setObject:recipiBookMark forKey:@"BookMarks"];

    BOOL filewrite = [recipieBM writeToFile:@"unicurd.plist" atomically:YES];
    if(filewrite)
    {
        //do somthing
    }
}

But it's not writing on file. The value of filewrite is showing YES but in plist it showing only item0 and value field blank.

You're trying to write to your app's bundle, which isn't allowed in iOS. Take a look at the answers to [this question from earlier today](http://stackoverflow.com/questions/5853014/writing-into-a-file-objective-c). — jscs, May 02 '11 at 09:00

try like this..

 [recipieBM writeToFile: pathProduct atomically:YES];

EDIT:

// Create the new dictionary that will be inserted into the plist.
NSMutableDictionary *nameDictionary = [NSMutableDictionary dictionary];
[nameDictionary setValue:@"John Doe" forKey:@"fullName"];
[nameDictionary setValue:@"555 W 1st St" forKey:@"address"];

// Open the plist from the filesystem.
NSMutableArray *plist = [NSMutableArray arrayWithContentsOfFile:@"/path/to/file.plist"];
if (plist == nil) plist = [NSMutableArray array];
[plist addObject:nameDictionary];
[plist writeToFile:@"/path/to/file.plist" atomically:YES];

You should write to the file path that you obtained from documents directory

if(![fileManager fileExistsAtPath:pathProduct])
    {
    NSString *bundlePath=[[NSBundle mainBundle] pathForResource:@"unicurd" ofType:@"plist"];
        [fileManager copyItemAtPath:bundlePath toPath:pathProduct error:&error];

    }


    NSString *recipiBookMark= pageURL;

    NSMutableDictionary *recipieBM = [[NSMutableDictionary alloc] init];
    [recipieBM setObject:recipiBookMark forKey:@"BookMarks"];

    BOOL filewrite = [recipieBM writeToFile:pathProduct atomically:YES];
    if(filewrite)
    {
        //do somthing
    }
}
