数据未添加到 Plist

Question

您好，我在 xcode 中创建了一个 plist（newfile->resourses->property list 像这样），我尝试将一个 NSDictionary 添加到该 plist 但它没有添加，请帮助我这是我的代码

    -(IBAction)Add:(id)sender {
     _pdfbookmark = [NSMutableArray arrayWithArray:[[NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"pdfBookmarksdata" ofType:@"plist"]] objectForKey:_bookID]];

     NSMutableDictionary *bookmark = [NSMutableDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"pdfBookmarksdata" ofType:@"plist"]];

     if(self.bookmarkIndicator.tintColor == [UIColor blueColor]){
        //Already Bookmarked
        [_pdfbookmark removeObjectAtIndex:currentBookmarkIndex];
        self.bookmarkIndicator.tintColor = [UIColor whiteColor];
     }else{
        //Create Bookmark
        [_pdfbookmark addObject:
        @{@"deviceid": @"0",
        @"page" : [NSNumber numberWithInt:[self getGlobalPageCount]],
        @"fontsize" : [NSNumber numberWithInt:currentTextSize]}];
        self.bookmarkIndicator.tintColor = [UIColor blueColor];
   }
    [bookmark setObject:_pdfbookmark forKey:_bookID];
    [bookmark writeToFile:[[NSBundle mainBundle] pathForResource:@"pdfBookmarksdata" ofType:@"plist"] atomically:YES];
 }

您不能将文件写入主包。如果你检查writeToFile:方法的返回，你会看到它返回NO。
