请问能否支持textview显示包含有MPITextAttachment的富文本？

我在使用MPITextKit中发现一个小问题。
将普通字符串解析为包含View的富文本字符串是比较耗时的，应在子线程解析。
但是如果MPITextAttachment的content是view或layer，又面临子线程操作View的问题。
因此是否可以让MPITextAttachment支持View的懒加载。

实现思路大致如下：

/// 定义一个MPITextAttachmentContent协议用来懒加载View
@objc protocol MPITextAttachmentContent: NSObjectProtocol {
    @objc var view: UIView? { get }
    @objc func removeView()
}


/// 示例
class CSTextAttachmentContent: NSObject, MPITextAttachmentContent {
    // CSTextComponent是一个枚举类型，可以用来生成不同类型的View
    let component: CSTextComponent
    private(set) lazy var view: UIView? = {
        return component.attachmentView
    }()
    
    init(component: CSTextComponent) {
        self.component = component
    }
    
    func removeView() {
        view?.removeFromSuperview()
    }
    
}


/// 重写MPITextAttachment
- (void)drawAttachmentInRect:(CGRect)rect textView:(UIView *)textView {
    UIView *view = nil;
    CALayer *layer = nil;
    UIImage *image = nil;
    if ([self.content isKindOfClass:[UIView class]]) {
        view = self.content;
    }  else if ([self.content conformsToProtocol:@protocol(MPITextAttachmentContent)]){
        id<MPITextAttachmentContent> c = self.content;
        view = c.view;
    }  else if ([self.content isKindOfClass:[CALayer class]]) {
        layer = self.content;
    } else if ([self.content isKindOfClass:UIImage.class]) {
        image = self.content;
    }
    
    if (image) {
        [image drawInRect:rect];
    } else if (view) {
        if (!CGRectEqualToRect(view.frame, rect)) {
            view.frame = rect;
        }
        if (view.superview != textView) {
            [textView addSubview:view];
        }
    }else if (layer){
        if (!CGRectEqualToRect(layer.frame, rect)) {
            layer.frame = rect;
        }
        if (layer.superlayer != textView.layer) {
            [textView.layer addSublayer:layer];
        }
    }
}

您好，我们文本有双击处理其他事件的功能，这时候如果双击的是文本超链接内容 会和我们双击出发的事件有冲突，会导致两个都执行。那我有什么办法把超链接的双击事件获取到，或者屏蔽掉么。

objc[245]: Class _NSZombie__MPILinkedMapNode is implemented in both ?? (0x1c5644170) and ?? (0x1c56441a0). One of the two will be used. Which one is undefined.

当文本是纯表情Unicode或者含有表情Unicode，进行选择复制，会导致复制失败，应该是选择的范围不正确。

还请作者能修复下

没有看到有地方使用MPITextParser的代码

[self.nameMPILabel mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(contentView).offset(12);
make.left.equalTo(contentView);
make.right.equalTo(contentView).offset(-12);
}];

{
NSMutableAttributedString *text = [NSMutableAttributedString new];
UIFont *font = [UIFont systemFontOfSize:14];

        image = [UIImage imageWithCGImage:image.CGImage scale:2 orientation:UIImageOrientationUp];
        MPITextAttachment *attach = [MPITextAttachment new];
        attach.content = image;
        NSMutableAttributedString *attachText = [[NSAttributedString attributedStringWithAttachment:attach] mutableCopy];
        [text appendAttributedString:attachText];
        
        [text appendAttributedString:[[NSAttributedString alloc] initWithString:@" " attributes:nil]];
        
        NSString *title = @"fffffffffffffffffff";
        [text appendAttributedString:[[NSAttributedString alloc] initWithString:title attributes:nil]];
        
        [text addAttribute:NSFontAttributeName value:font range:text.mpi_rangeOfAll];
        self.nameMPILabel.attributedText = text;

}

如何重现
1、info.plist只勾选Portrait

2、AppDeleagte里实现

3、MPITextSelectionViewController实现

4、进入MPITextSelectionViewController后长按文字出现『菜单』然后选择区域，主要是「保证MPITextEffectWindow单例被创建」
5、横竖屏切换即可复现

可复现的Demo，全局搜索语句"MPITextKit/issues" 查看改动的地方
MPITextKit_issue.zip

解决方案
在Demo中，「MPITextEffectWindow.m的37行」，使用MPITextEffectWindowViewController代替UIViewController

如上图，左侧那个标签应该显示在右侧红线位置，但是目前显示异常了， 当点击右侧的昵称（是一个MPITextLink）时，会恢复正常显示。

PS:设置标签和链接的部分代码如下：

//标签
let attachment = MPITextAttachment()
attachment.content = liveAnchorView //这里是个UIView
attachment.verticalAligment = .center
attachment.contentSize = liveAnchorView.anchorSize
attachment.contentMode = .scaleAspectFit
let tempAttr = NSMutableAttributedString(attachment: attachment)

//链接
attributedString.mpi_setAttribute(NSAttributedString.Key.MPILink.rawValue, value: MPITextLink(value: selectorStr as NSObjectProtocol), range: rangeVal)
attributedString.mpi_setAttribute(NSAttributedString.Key.foregroundColor.rawValue, value: rangeColor as Any, range: rangeVal)

另外，为了让Label支持显示为RTL方式，需要给paragraphStyle设置属性baseWritingDirection的值为.rightToLeft：

let isRTL = UIApplication.shared.userInterfaceLayoutDirection == .rightToLeft
let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.baseWritingDirection = isRTL ? .rightToLeft : .leftToRight
paragraphStyle.alignment = .natural
finalAttr.addAttribute(.paragraphStyle, value: paragraphStyle, range: NSRange(location: 0, length: finalAttr.length))

异步渲染时，attributedText为nil，不能复制。

发现给MPILabel设置textAlignment后，再给attributedText赋值，textAlignment是不会被用到，需要手动调一下
- (void)mpi_setAlignment:(NSTextAlignment)alignment range:(NSRange)range;
请问这里是基于什么考虑呢？

一般文本可以选择是长按文本触发的，现在遇到一个，假设第一次长按选择了全部的文本。然后触摸空白选择文本取消。这时候在文本上轻扫（比如：右下角往左上角扫动）就可以再触发选择而不是通过长按触发。麻烦作者看下

问题：
业务设置MPILabel的accessibilityLabel、accessibilityAttributedLabel不生效

原因：
MPILabel重写了「accessibilityLabel、accessibilityAttributedLabel」的getter方法，导致业务不管怎么设置都不会生效，苹果文档里这两个属性可以set。

建议：
既满足外部可以设置accessibility，又不影响之前版本的适配

iOS 13系统以下， 内容过长时，异步渲染，渲染不出来！高度5500以上就渲染不出来

在给出的Example MPITextKit Demo中测试点击Text Attachment，可以明显看到内存泄露导致的内存增长。

通过 [label sizeThatFits:CGSizeMake(textMaxWidth, MAXFLOAT)]; 方法计算文本的所需要的高度，如果富文本中没有换行操作，是正常的，如果有换行操作，计算的size大小会偏高。我同时设置了行高样式
NSMutableParagraphStyle *paragraphStyle =[[NSMutableParagraphStyle alloc] init];
[paragraphStyle setParagraphStyle:[NSMutableParagraphStyle defaultParagraphStyle]];
paragraphStyle.lineHeightMultiple = 1.2;
[attributedString addAttributes:@{NSParagraphStyleAttributeName:paragraphStyle} range:NSMakeRange(0,attributedString.length)];

YYText 的 Text Attriutes Demo当中，我长按一个标签或者link，并不会像MPITextKit 那样子，直接就触发点击事件，而是当点击才会真正触发，不知道 MPITextKit 能否修改下。

如图所示:两个都是MPILabel,想要换行必须设置preferredMaxLayoutWidth么？不设置的时候换行异常。

您好，请教一下，如果一个页面有多个文本框，那怎么可以做到文本选择只能对一个文本框进行操作。目前来看选中是多个文本可以共存，会导致选中的移动手势响应有问题。然后我可以把手势的响应范围增加么。

像图片中随意选择后，现在已经无法进行区域选择了

。

您好，这个库的可以任意选择文字功能太棒了，解决了我一直困扰的问题。超链接自定义效果使用起来也是很简洁方便。我现在遇到一个问题，我的文本字段图文混排的时候表情显示不太正常，会被拉伸。我用了两种写法，一种是找到表情位置进行替换。一种是直接appendAttributedString 都会出现拉伸问题

1、问题：selectable = true时，在文本「MPITextLinkAttributeName」的范围外，文本内点击，则不会有任何响应，导致无法触发其他点击事件。另外，点击除MPILabel外的地方，selectable的选中范围也不会消失。
2、场景：例如，我在UICollectionViewCell上加了MPILabel，给文本中的一小段文字加了「MPITextLinkAttributeName」实现富文本点击效果，如果我点击文本的其他区域就无法触发UICollectionView的didSelectItemAtIndexPath代理。
3、期望：开启selectable的情况下，但是未出现选择区域时，点击时MPILabel需要响应其他的点击事件。另外，点击除MPILabel外的地方也应该让选择区域消失
4、可复现的Demo:
「MPITextTruncatingViewController」里有注释的代码可以测试

MPITextKit-master.zip

autolayout跟attributedText，计算出来的宽度是偏小的，导致文字被break成了。。。

在MPITextAttachment添加UIButton作为content，会导致内存泄漏，UIButton释放不掉

OC：

    NSMutableAttributedString *attributedText = [NSMutableAttributedString new];
    NSAttributedString *linkAttributedText = [[NSAttributedString alloc] initWithString:@"Tap Me dsdsdsldslkdlskdlsd"];
    [attributedText appendAttributedString:linkAttributedText];
    
    MPITextBackground *background = [MPITextBackground backgroundWithFillColor:[UIColor grayColor] cornerRadius:5];
    [attributedText addAttribute:MPITextBackgroundAttributeName value:background range:NSMakeRange(0, 8)];

    MPILabel *label = [MPILabel new];
    label.highlightedLinkTextAttributes = nil;
    label.delegate = self;
    label.numberOfLines = 0;
    label.attributedText = attributedText;
    label.frame = CGRectMake(0, 200, 300, 100);
    [self.view addSubview:label];

Swift

        let helloWorldAttributedText = NSMutableAttributedString.init(string: "Tap Me dsdsdsldslkdlskdlsd")
        let attributedText = NSMutableAttributedString.init()
        attributedText.append(helloWorldAttributedText)

        let background = MPITextBackground(fill: .gray, cornerRadius: 5)
        attributedText.addAttribute(NSAttributedString.Key.MPIBlockBackground, value: background, range: .init(location: 0, length: 5))
        
        let mpiLabel = MPILabel.init()
        mpiLabel.highlightedLinkTextAttributes = nil
        mpiLabel.numberOfLines = 0
        mpiLabel.delegate = self
        mpiLabel.attributedText = attributedText
        mpiLabel.frame = .init(x: 0, y: 200, width: 300, height: 100)

        self.view.addSubview(mpiLabel)

1.长按滑动选择过程中，触控不灵敏，触控过小。如何可以扩大范围。
2.选择滑动过程中。没有选择范围变化的监听回调。是否考虑加上。
还望大佬给予指点

UIGraphicsBeginImageContextWithOptions，在iOS17上触发断言闪退，这个API17已经弃用，size的width和height有一个为0就会触发

我直接用例子里的 我的阿勒泰... 那段文本 label 设置 label.textAlignment = NSTextAlignmentCenter; 发现文本并没有居中对齐。只有设置了 [one mpi_setAlignment:NSTextAlignmentCenter range:one.mpi_rangeOfAll]; 才居中对齐起作用。

如题

e.g. attributedString like "aaa [fun][fun][fun] aaaaa"
i will replace [fun] to a image, with MPITextAttachment, using replaceCharacters function.
when the string like this "[a][b]" replace fine, but the string like "[a][a]" i won't get two image, i just a one twice width's image
but i change the MPITextAttachment to NSTextAttachment, just work fine.

UIScrollView里面添加MPILabel ，MPILabel编辑状态，长按选择后拖动选择框，有没有回调，让外层的UIScrollView也跟着滚动?

用demo 中MPITextSelectionViewController 修改成frame布局 ，选择文字时手势响应范围变小。基本都在绿色线条标记的地方才可以响应拖动。kGrabberTouchHitTestExtend  kKnobTouchHitTestExtend这两个值设置很大也没有用。请问怎么样才能增大触控拖动的响应范围，这样会使操作看起来更灵敏一点。

textView.backgroundColor = [UIColor lightGrayColor];
textView.textContainerInset = UIEdgeInsetsMake(30, 30, 30, 30);
textView.frame = CGRectMake(30, 100, self.view.frame.size.width-60, 100)

这是我添加link的用法，是在tableViewCell里面使用的MPILabel。下图是友盟线上收集到Crash日志，目前暂时没找到复现场景，麻烦问下我的使用方法有问题么？如果没有，想问下大佬能否优化下这个越界的问题。
