UIScrollView嵌套UITableView和UICollectionView

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];
