如何禁用选择，全选，建议... ，定义等弹出式菜单项（在 UIWebView ）？

How to disable popup menu items like Select, Select All, Suggest..., Define (on UIWebView)?

我在帮助中找到了以下信息，但不明白如何使用它：

I have found the following information on the help but don't understand how to use it:

对于编辑菜单命令，这是共享的 UIApplication
对象。根据上下文，您可以向发件人查询
信息，以帮助您确定是否应启用命令。

For the editing menu commands, this is the shared UIApplication object. Depending on the context, you can query the sender for information to help you determine whether a command should be enabled.

推荐答案

Swizzle以下方法：

Swizzle the following method:

#import "NSObject+myCanPerformAction.h"

@implementation NSObject (myCanPerformAction)

- (BOOL)myCanPerformAction:(SEL)action withSender:(id)sender {
    if (action == @selector(copy:)) {
        return [self myCanPerformAction:action withSender:sender]; // not a recursion
    }
    if (action == @selector(paste:)) {
        return [self myCanPerformAction:action withSender:sender]; // not a recursion
    }
    return NO;
}

@end

Swizzling：

Swizzling:

[[UIWebDocumentView class] jr_swizzleMethod:@selector(canPerformAction:withSender:) withMethod:@selector(myCanPerformAction:withSender:) error:nil];
