崩溃信息如下:
'Could not instantiate class named _UITextLayoutView because no class named _UITextLayoutView was found;
解决方案:
解决方案 一
1.xib的部分视图改用硬核手写,以避坑。
解决方案 二
2.[下载其他版本Xcode 传送门]
解决方案 三
3.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 版本如收下:
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!)
}
}
}
}
