    日常记录

          dispatch_group_t group = dispatch_group_create();

      dispatch_group_enter(group);
      dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
        dispatch_group_leave(group);
        NSLog(@"完成1");
      });

      dispatch_group_notify(group, dispatch_get_main_queue(), ^{
        NSLog(@"都完成后，执行");
      });

           let workingQueue = DispatchQueue(__label: "my_queue", attr: nil)
        let group = DispatchGroup()
        group.enter()//把该任务添加到组队列中执行
        workingQueue.async(group: group, qos: .default, flags: [], execute: {

    格式修改插件

    XCFormat

    常规的宏
    #define NSLogRect(rect) NSLog(@"%s x:%.4f, y:%.4f, w:%.4f, h:%.4f", #rect, rect.origin.x, rect.origin.y, rect.size.width, rect.size.height)
#define NSLogSize(size) NSLog(@"%s w:%.4f, h:%.4f", #size, size.width, size.height)
#define NSLogPoint(point) NSLog(@"%s x:%.4f, y:%.4f", #point, point.x, point.y)
    屏蔽Xcode报错
    #pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wundeclared-selector"//(具体报错内容)
{...}//可能出现报错的代码
#pragma clang diagnostic pop
    weak&strong 宏的声明

    留个坑，后面来辨别两种方式的优劣

    快速定义宏
// weak obj
#define WEAK_OBJ(type)  __weak typeof(type) weak##type = type;
// strong obj
#define STRONG_OBJ(type)  __strong typeof(type) str##type = weak##type;

    /**

#ifndef weakify
    #if DEBUG
        #if __has_feature(objc_arc)
        #define weakify(object) autoreleasepool {} __weak __typeof__(object) weak ## _ ## object = object;
        #else
        #define weakify(object) autoreleasepool {} __block __typeof__(object) block ## _ ## object = object;
        #endif
    #else
        #if __has_feature(objc_arc)
        #define weakify(object) try {} @finally {} {} __weak __typeof__(object) weak ## _ ## object = object;
        #else
        #define weakify(object) try {} @finally {} {} __block __typeof__(object) block ## _ ## object = object;
        #endif
    #endif
#endif

/**

#ifndef strongify
    #if DEBUG
        #if __has_feature(objc_arc)
        #define strongify(object) autoreleasepool {} __typeof__(object) object = weak ## _ ## object;
        #else
        #define strongify(object) autoreleasepool {} __typeof__(object) object = block ## _ ## object;
        #endif
    #else
        #if __has_feature(objc_arc)
        #define strongify(object) try {} @finally {} __typeof__(object) object = weak ## _ ## object;
