You can inspect and modify views in iOS app via Lookin, just like UI Inspector in Xcode, or another app called Reveal.

Official Website：https://lookin.work/

To use Lookin macOS app, you need to integrate LookinServer (iOS Framework of Lookin) into your iOS project.

Warning Never integrate LookinServer in Release building configuration.

Lookin 可以查看与修改 iOS App 里的 UI 对象，类似于 Xcode 自带的 UI Inspector 工具，或另一款叫做 Reveal 的软件。

如果这是你的 iOS 项目第一次使用 Lookin，则需要先把 LookinServer 这款 iOS Framework 集成到你的 iOS 项目中。

Warning 记得不要在 AppStore 模式下集成 LookinServer。

原理: 参考LKSConfigManager注入功能的方式, 加上动态执行oc代码的能力

@interface NSObject (KcLookinFeature1)

@end

@implementation NSObject (KcLookinFeature1)

/// JSON string
/// { title: xx, methodName: 方法名, isUIViewMethod: 是否uiview的方法 }
+ (NSArray<NSDictionary<NSString *, id> *> *)lookin_kc_injectMethods {
    
    NSArray<NSDictionary<NSString *, id> *> *list = @[
        @{
            // @Class 会被替换成当前lookin item的类名
            @"methodName": @"[NSObject kc_dump_propertyDescriptionForClass:@Class]",
            @"isUIViewMethod": @NO,
            @"title": @"dump当前class属性",
        },
        @{
            // self 会替换成当前lookin item 对象那个view、viewController
            @"methodName": @"[self kc_dump_autoLayoutHierarchy]",
            @"isUIViewMethod": @YES,
            @"title": @"自动布局",
        },
    ];
    
    return list;
}

+ (NSArray<NSDictionary<NSString *, id> *> *)lookin_kc_injectKeyPathMethods {
    
    NSArray<NSDictionary<NSString *, id> *> *list = @[
        @{
            @"methodName": @"[KcFindPropertyTooler searchPropertyWithValue:self keyPath: %@]",
            @"isUIViewMethod": @NO,
            @"title": @"查询属性value",
        },
    ];
    
    return list;
}

@end

实现在LKSConfigManager类中

// 可以传入keyPath参数的方法
@"[NSObject lookin_kc_injectKeyPathMethods]",
// 0 ~ 4
@"[NSObject lookin_kc_injectKeyPathMethods_0]",

// 不能传入参数的方法
@"[NSObject lookin_kc_injectMethods]",
// 0 ~ 4
@"[NSObject lookin_kc_injectMethods_0]",
