Answer 1

Is the plist a part of your resources? Not sure if we can edit a plist there. Copy the plist to your app's Documents folder and update it there.

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

success = [fileManager fileExistsAtPath:plistPath];
if(!success){
    //file does not exist. So look into mainBundle
    NSString *defaultPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"TopicsList.plist"];
    success = [fileManager copyItemAtPath:defaultPath toPath:plistPath error:&error];
}

Now whatever changes you need to make to the plist or read data from the plist, read it from the copy in Documents folder.
