如何在iPad上以两列显示文本

Question

我想在两列中显示某个文本，就像这样:

================
line1  line4  ||
line2  line5  ||
line3  line6  ||
------------  ||
prev  next    ||

================

我不希望文本有垂直或水平滚动只是适合在区域内。

我不知道使用哪个视图或布局-因为我是IOS开发的新手-

谢谢

如果你有一些html技能，你可以使用UIWebView以任何你可以在标记中实现的方式来显示你的文本。

页面http://www.cocoanetics.com/2011/01/befriending-core-text/解释了如何使用CoreText框架和NSAttributedString显示两列文本。

使用UITextview显示两列文本:

//Declare global variables. 
    NSLayoutManager *_layoutManager;
    NSTextStorage *_textStorage;
    UIScrollView *scrollView;
//Create a scrollview and add it on the main view.
 scrollView=[[UIScrollView alloc]initWithFrame:CGRectMake(10, 10, screenWidth-20, screenHeight-20)];
        [self.view addSubview:scrollView];
//Get the file url path of .txt file.
 NSURL *contentURL = [[NSBundle mainBundle] URLForResource:@"introduction" withExtension:@"txt"];
//Create text storage :
_textStorage = [[NSTextStorage alloc] initWithFileURL:contentURL
                                                  options:nil
                                       documentAttributes:NULL
                                                    error:NULL];
//Create a layout manager and add it to textstorage
 _layoutManager = [[NSLayoutManager alloc] init];
    [_textStorage addLayoutManager:_layoutManager];
//then call the method
 [self layoutTextContainers];

方法定义:

   -(void)layoutTextContainers{
        NSUInteger lastRenderedGlyph = 0;
        CGFloat currentXOffset = 0;
        while (lastRenderedGlyph < _layoutManager.numberOfGlyphs) {
         CGRect textViewFrame = CGRectMake(currentXOffset, 10,
                                           CGRectGetWidth(scrollView.bounds) / 2,
                                              CGRectGetHeight(scrollView.bounds) - 20);
            CGSize columnSize = CGSizeMake(CGRectGetWidth(textViewFrame) - 20,
                                           CGRectGetHeight(textViewFrame) - 10);
            NSTextContainer *textContainer = [[NSTextContainer alloc] initWithSize:columnSize];
            [_layoutManager addTextContainer:textContainer];
            // And a text view to render it
            UITextView *textView = [[UITextView alloc] initWithFrame:textViewFrame
                                                    textContainer:textContainer];
            textView.scrollEnabled = NO;
            [introTextScrollView addSubview:textView];
            // Increase the current offset
            currentXOffset += CGRectGetWidth(textViewFrame);
            // And find the index of the glyph we've just rendered
            lastRenderedGlyph = NSMaxRange([_layoutManager glyphRangeForTextContainer:textContainer]);
        }
        // Need to update the scrollView size
        CGSize contentSize = CGSizeMake(currentXOffset, CGRectGetHeight(introTextScrollView.bounds));
        introTextScrollView.contentSize = contentSize;
    }

我认为你可以添加2个相同大小的uitextview。在左边，你可以写第1、2和3行，在其他的第4、5和6行
