iOS10.3.3 webView 点击网页中的输入框会crash

[lauran404]

Bug 表现 在iOS10系统运行, webView加载网页后, 点击网页中的输入框会发生闪退. 通过断点调试发现是框架如下方法导致闪退:

UISearchBar +load 方法中重写UINavigationButton setEnabled, 注释掉以下框架方法能恢复正常: OverrideImplementation(NSClassFromString(@"UINavigationButton"), @selector(setEnabled:), ^id(__unsafe_unretained Class originClass, SEL originCMD, IMP (^originalIMPProvider)(void)) { return ^(UIButton *selfObject, BOOL firstArgv) {

            UISearchBar *searchBar = nil;
            if (@available(iOS 13.0, *)) {
                searchBar = (UISearchBar *)selfObject.superview.superview.superview;
            } else {
                searchBar = (UISearchBar *)selfObject.superview.superview;
            }

            if ([searchBar isKindOfClass:UISearchBar.class] && searchBar.qmui_alwaysEnableCancelButton && !searchBar.qmui_searchController) {
                firstArgv = YES;
            }

            // call super
            void (*originSelectorIMP)(id, SEL, BOOL);
            originSelectorIMP = (void (*)(id, SEL, BOOL))originalIMPProvider();
            originSelectorIMP(selfObject, originCMD, firstArgv);
        };
    });

如何重现

1. iOS10.3.3系统
2. 点击webView中输入框, 出现闪退
