Xcode 11 Xib _UITextLayoutView 崩溃

作为一个开发者，有一个学习的氛围跟一个交流圈子特别重要，这是一个我的iOS交流群：196800191，加群密码：112233，不管你是小白还是大牛欢迎入驻 ，分享BAT,阿里面试题、面试经验，讨论技术， 大家一起交流学习成长！

崩溃信息如下：

*** Terminating app due to uncaught exception 
'NSInvalidUnarchiveOperationException', 
reason: 'Could not instantiate class named _UITextLayoutView because no class named _UITextLayoutView was found; 
the class needs to be defined in source code or linked in from a library (ensure the class is part of the correct target)'

解决方案：

解决方案 一

xib的部分视图改用硬核手写，以避坑。

解决方案 二

下载其他版本Xcode 传送门

解决方案 三

OC 黑魔法 Runtime。

创建 文件 UITextViewWorkaround

UITextViewWorkaround.h

#import <Foundation/Foundation.h>
 
@interface UITextViewWorkaround : NSObject
+ (void)executeWorkaround; 
@end

UITextViewWorkaround.m

#import "UITextViewWorkaround.h"
#import  <objc/runtime.h>
 
 
@implementation UITextViewWorkaround
 
+ (void)executeWorkaround {
    if (@available(iOS 13.2, *)) {
 
    }
    else {
        const char *className = "_UITextLayoutView";
        Class cls = objc_getClass(className);
        if (cls == nil) {
            cls = objc_allocateClassPair([UIView class], className, 0);
            objc_registerClassPair(cls);
#if DEBUG
            printf("added %s dynamically\n", className);
#endif
        }
    }
}
 
@end

使用该静态方法

#import "UITextViewWorkaround.h"
 
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
 
    [UITextViewWorkaround executeWorkaround];
    return yes;
}

swift 版本请客观收下：

import UIKit
 
@objc
class UITextViewWorkaround : NSObject {
 
    static func executeWorkaround() {
        if #available(iOS 13.2, *) {
        } else {
            let className = "_UITextLayoutView"
            let theClass = objc_getClass(className)
            if theClass == nil {
                let classPair: AnyClass? = objc_allocateClassPair(UIView.self, className, 0)
                objc_registerClassPair(classPair!)
            }
        }
    }
 
}
