仿微信悬浮窗,可直接协议加入悬浮窗或者直接调用方法注册,可自定义转场动画

Github地址(WMZFloatView)

演示

用法1 在Appdelegate中注册传入对应控制器的className

 //只带控制器的className 
 [[WMZFloatManage shareInstance] registerControllers:@[@"ViewController"]];
  //带其他配置(标题和图片)
[[WMZFloatManage shareInstance]    registerControllers:@[@{@"controllerName":@"ViewController",@"icon":@"float_circle_full"}]];

用法2 实现协议 WMZFloatViewProtocol 即可

 //可选实现协议的方法 传入标题和图片
  - (NSDictionary *)floatViewConfig{
    return @{@"name":@"实际显示在悬浮窗的标题",@"icon":@"float_image"};
 }

用法3 改变转场动画传入继承UIViewControllerAnimatedTransitioning协议的类即可

//自定义push动画
@property(nonatomic,strong)NSObject<UIViewControllerAnimatedTransitioning> *pushAnimal;
//自定义pop动画
@property(nonatomic,strong)NSObject<UIViewControllerAnimatedTransitioning>  *popAnimal;

讲解

来说下我的实现思路

1 浮动框

1 实现一个悬浮窗的单例管理器,继承UINavigationControllerDelegate,UIGestureRecognizerDelegate

2 监听侧滑手势是否开始

  //监听侧滑手势开始
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer{
if ([gestureRecognizer isKindOfClass:[UIScreenEdgePanGestureRecognizer class]]&&self.nowVC.navigationController.viewControllers.count>1) {
    //判断是否实现了协议 加入可悬浮
    BOOL isConform = [self.nowVC conformsToProtocol:@protocol(WMZFloatViewProtocol)];
    NSString *tmpName = NSStringFromClass([self.nowVC class]);
    if (isConform) {
        if ([self.reginerVCName indexOfObject:tmpName] == NSNotFound) {
            NSMutableDictionary *mdic = [NSMutableDictionary new];
            [mdic setObject:tmpName forKey:@"controllerName"];
            //实现了配置的协议 加入配置
            if ([self.nowVC respondsToSelector:@selector(floatViewConfig)]) {
                NSDictionary *dic = [self.nowVC performSelector:@selector(floatViewConfig)];
                [dic enumerateKeysAndObjectsUsingBlock:^(id  _Nonnull key, id  _Nonnull obj, BOOL * _Nonnull stop) {
                    [mdic setObject:obj forKey:key];
                }];
            }
            [self.reginerVCName addObject:tmpName];
            [self.reginerVCConfig setObject:mdic forKey:tmpName];
        }
    }
    //达到可悬浮的条件
    if ([self.reginerVCName indexOfObject:tmpName] != NSNotFound && [self.cacheKey indexOfObject:[self getKey:self.nowVC]] == NSNotFound){
        self.edge = (UIScreenEdgePanGestureRecognizer *) gestureRecognizer;
        [self.link addToRunLoop:[NSRunLoop mainRunLoop] forMode:NSRunLoopCommonModes];
        [faloatWindow addSubview:self.floatView];
        self.normalRect = self.floatView.frame;
        CGRect rect = self.floatView.frame;
        rect.origin.x = FloatWidth;
        rect.origin.y = FloatHeight;
        self.floatView.frame = rect;
        self.floatView.full = (self.cacheKey.count>=5);
    }
    
}
return YES;

}

3 监听侧滑触碰点是否碰到悬浮窗

 //圆心到点的距离>?半径
 + (BOOL)point:(CGPoint)point inCircleRect:(CGRect)rect {
     CGFloat radius = rect.size.height;
     CGPoint center = CGPointMake(rect.origin.x + radius, rect.origin.y + radius);
     double dx = fabs(point.x - center.x);
     double dy = fabs(point.y - center.y);
     double dis = hypot(dx, dy);
     return dis <= radius;
 }
