UIScrollView嵌套UITableView和UICollectionView

项目中分类页面如下

设置

    self.edgesForExtendedLayout = UIRectEdgeNone;
    self.automaticallyAdjustsScrollViewInsets = NO;
    self.extendedLayoutIncludesOpaqueBars = NO;

创建View

contentView =[[UIScrollView alloc]initWithFrame:self.view.bounds];
    contentView.autoresizingMask = UIViewAutoresizingFlexibleHeight;
    [self.view addSubview:contentView];
    KHRefreshHeader *mj_header = [KHRefreshHeader headerWithRefreshingBlock:^{
        [weakSelf getDataForCategory:nil];
    }];
    contentView.mj_header = mj_header;
//tableview
    tableview = [[UITableView alloc]initWithFrame:CGRectMake(0, 0,100, CGRectGetHeight(self.view.bounds)) style:UITableViewStylePlain];
    tableview.allowsMultipleSelection = NO;
        UIView *cv=  contentView;
        [cv addSubview:tableview];
        //collectionView
         CGRect cvFrame = CGRectMake(CGRectGetMaxX(tableview.frame), 0, CGRectGetWidth(self.view.frame)-CGRectGetWidth(tableview.frame), CGRectGetHeight(contentView.frame));
    UICollectionViewFlowLayout *flowout = [[UICollectionViewFlowLayout alloc]init];
    flowout.itemSize = CGSizeMake((cvFrame.size.width - 4*10)/3, 100);
    flowout.sectionInset = UIEdgeInsetsMake(5,5,0,5);
    flowout.headerReferenceSize = CGSizeMake(CGRectGetWidth(cvFrame), 30);
    flowout.minimumLineSpacing = 5;//每行相隔的距离
    flowout.minimumInteritemSpacing = 10;//每列相隔的最小距离
    collectionView = [[UICollectionView alloc]initWithFrame:cvFrame collectionViewLayout:flowout];
    collectionView.autoresizingMask = UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;
    collectionView.backgroundColor = [UIColor whiteColor];
    collectionView.scrollEnabled = YES;
    [cv addSubview:collectionView];

ok 。这样就解决了，子view显示补全的问题
注:代码中的KHRefreshHeader 是集成MJRefreshNormalHeader的。
即项目中用的下拉刷新第三方控件#import
