#xcode11.2 #XIB的TextView崩溃

本文介绍了一种解决iOS 13.2中UITextView布局问题的方法，通过Objective-C Runtime动态注册类来修复布局显示异常，确保应用在不同iOS版本上正常运行。

一，TextView用纯代码写。

二，oc的Runtime，创建文件 UITextViewWorkaround

#import <Foundation/Foundation.h>

@interface UITextViewWorkaround : NSObject
+ (void)executeWorkaround;
@end

#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

#import "UITextViewWorkaround.h"

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.

    [UITextViewWorkaround executeWorkaround];
    return yes;
}

再运行就好了
