Xcode 11 Xib _UITextLayoutView 崩潰
Xcode升級(jí)11.2之后型凳，xib中使用UITextView突然閃退
之后看到大神轉(zhuǎn)的文章完美解決了問(wèn)題振亮，參考原文稍作了修改 https://blog.csdn.net/zzsatym/article/details/102919289
我的崩潰信息如下：
*** 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)'
*** First throw call stack:
(0x1b4a0498c 0x1b472d0a4 0x1b48fa054 0x1b7fad6f8 0x1b7fada6c 0x1b7f49ec8 0x1b8e6d354 0x1b8e13f2c 0x1b8d09248 0x1046147e0 0x1046148a0 0x1b86bbc2c 0x1b7fad838 0x1b7f49ec8 0x1b86bfc7c 0x1b7fad838 0x1b7fada6c 0x1b7f49ec8 0x1b86bacc8 0x1b86bd8b8 0x1b8404b4c 0x1b84055d8 0x1b8405890 0x1b8405f94 0x1b8365804 0x1b8378de8 0x1b837a2ec 0x1b835e060 0x1b8e9d270 0x1bb3895f8 0x1bb38de28 0x1bb399894 0x1bb2e29f0 0x1bb30c890 0x1bb30d284 0x1b4981c48 0x1b497cb34 0x1b497d100 0x1b497c8bc 0x1be7e8328 0x1b8a126d4 0x10461cd10 0x1b4807460)
libc++abi.dylib: terminating with uncaught exception of type NSException
3個(gè)解決方案：
UITextView使用純代碼可以有效避坑
使用Runtime黑魔法
創(chuàng)建 文件 UITextViewWorkaround 繼承 NSObject
- swift
import UIKit
@objcMembers
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!)
}
}
}
}
- OC .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
最后在AppDelegate調(diào)用即可
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
UITextViewWorkaround.executeWorkaround()
return true
}
