    af 的方法交换处理
static inline void af_swizzleSelector(Class class, SEL originalSelector, SEL swizzledSelector) {
    Method originalMethod = class_getInstanceMethod(class, originalSelector);
    Method swizzledMethod = class_getInstanceMethod(class, swizzledSelector);
    if (class_addMethod(class, originalSelector, method_getImplementation(swizzledMethod), method_getTypeEncoding(swizzledMethod))) {
        class_replaceMethod(class, swizzledSelector, method_getImplementation(originalMethod), method_getTypeEncoding(originalMethod));
    } else {
        method_exchangeImplementations(originalMethod, swizzledMethod);
    }

}

    数据采集

    • uiviewcontroller的生命周期，用于测算页面停留时间加载时间等

    1.viewDidAppear上报页面进入事件。
    2.viewDidDisappear上报页面退出事件
    即可得出用户访问页面路径，两个事件时间戳之差即为用户在页面停留的时间。

    统计数据字段
    1.PAGE_ID，当前页面的标识。 【一般用类名】
    2.SOURCE_ID，当前页面的前一个页面的标识。【获取上一个页面的类名】
    3.TYPE_ID,当前页面一些关键信息。
    4.TIMESTAMP，当前事件生成的时间戳。
    5.页面进入和退出的事件，均上报上述的数据结构。
    6.跟进上面的记录通过计算可以获得VC的路径

    + (void)install {
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        [Tool replaceImplementationOfKnownSelector:@selector(viewDidAppear:) onClass:[self class]];
        [Tool replaceImplementationOfKnownSelector:@selector(viewDidDisappear:) onClass:[self class]];
    });
}

- (void)br_viewDidAppear:(BOOL)animated {
    NSLog(@"[%@--%@]", NSStringFromClass([self class]), NSStringFromSelector(_cmd));
    [self br_viewDidAppear:animated];
}


- (void)br_viewDidDisappear:(BOOL)animated {
    NSLog(@"[%@--%@]", NSStringFromClass([self class]), NSStringFromSelector(_cmd));
    [self br_viewDidDisappear:animated];
}
    • UIControl（UISwitch，UIStepper，UISegmentedControl， UINavigationButton，UISlider，UIButton）类控件的点击事件
    + (void)install {
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        [Tool replaceImplementationOfKnownSelector:@selector(sendAction:to:from:forEvent:) onClass:[self class]];
    });
}

- (BOOL)br_sendAction:(SEL)action to:(id)target from:(id)sender forEvent:(UIEvent *)event {
    
    NSLog(@"=====");
    
    return [self br_sendAction:action to:target from:sender forEvent:event];
}
    • UIView上的GestureRecognizer触摸事件
     在uiview的分类中添加target
#import <objc/runtime.h>
+ (void)startTracker {
    Method addGestureRecognizerMethod = class_getInstanceMethod(self, @selector(addGestureRecognizer:));
    Method ddAddGestureRecognizerMethod = class_getInstanceMethod(self, @selector(dd_addGestureRecognizer:));
    method_exchangeImplementations(addGestureRecognizerMethod, ddAddGestureRecognizerMethod);
}

- (void)test:(UIGestureRecognizer *)gest {
    
}

- (void)dd_addGestureRecognizer:(UIGestureRecognizer *)gestureRecognizer {
    
    [gestureRecognizer addTarget:self action:@selector(test:)];
    
    [self dd_addGestureRecognizer:gestureRecognizer];
    • UICollectionView和UITableView的cell点击事件
    @implementation UITableView (DDAutoTracker)

+ (void)startTracker {
    Method setDelegateMethod = class_getInstanceMethod(self, @selector(setDelegate:));
    Method ddSetDelegateMethod = class_getInstanceMethod(self, @selector(dd_setDelegate:));
    method_exchangeImplementations(setDelegateMethod, ddSetDelegateMethod);
}

- (void)dd_setDelegate:(id <UITableViewDelegate>)delegate {
    
    //只监听UITableView
    if (![self isMemberOfClass:[UITableView class]]) {
        return;
    }

            method_exchangeImplementations(originMethod, swizzlMethod);
        }
    }

                                                        info:infoDictionary];
}

@end

    • UITabBar、UIAlertView、UIActionSheet等的点击事件
    hook delegate 然后hook点击事件的代理方法
唯一标识 使用title message 按钮内容 再加上路径

    • RN采集

    • app内OpenURL 主要是应用直接的跳转回调等

    hook UIApplicationDelegate协议对象，直接hook appdelegate或者写它的分类，可能会失败（原因：某些用户可能会自定义文件名，默认加前缀，XXAppdelegate）
还有其生命周期方法一并hook

需要判断方法是否实现，未实现添加实现（本人一直操作失败），已实现进行交换

application:handleOpenURL:
application:openURL:options:
    • UItextview uitextfiled uisearchbar
      根据代理处理

    数据缓存

    • 默认的存储模式【个人想法内存】
    • 考虑用户杀掉程序或者崩溃时数据如何持久化存储
    • 持久化保存方式【json？plist？db？】哪种性能更好？
    • 文件量限制，时间限制 【记录10条数据就开始上传一次，或者1分钟一次】
    • 缓存格式？

    构建json协议

    传输数据
