LTScrollView
实现原理： http://blog.csdn.net/glt_code/article/details/78576628
Demo文件路径以及说明
- LTScrollView / Example : 为 Swift 使用示例.
- LTScrollView / OCExample : 为 OC 使用示例.
- 支持的子View为UIScrollView、UICollectionView、UITableView.
CocoaPods安装
安装CocoaPods 使用以下命令：
$ gem install cocoapods
Podfile
在你的 Podfile中添加LTScrollView
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
target 'TargetName' do
#注意此处需要添加use_frameworks!
use_frameworks!
pod 'LTScrollView', '~> 0.2.0'
end
然后，使用以下命令安装
$ pod install
提示错误 [!] Unable to find a specification for LTScrollView 解决办法：
$ pod repo remove master
$ pod setup
Swift使用说明
Swift.LTSimple使用说明
- 创建LTSimpleManager实例对象
@objc public init(frame: CGRect, viewControllers: [UIViewController], titles: [String], currentViewController:UIViewController, layout: LTLayout)
- 设置headerView
@objc public func configHeaderView(_ handle: (() -> UIView?)?)
- 子控制器中glt_scrollView进行赋值
self.glt_scrollView = self.tableView（self.scrollView / self.collectionView）
- 更多使用说明请参考Demo（LTScrollView / Example）
Swift.LTAdvanced使用说明
class FMPlayDetailController: UIViewController {
- 创建LTAdvancedManager实例对象、并设置headerView
@objc public init(frame: CGRect, viewControllers: [UIViewController], titles: [String], currentViewController:UIViewController, layout: LTLayout, headerViewHandle handle: () -> UIView)
- 子控制器中glt_scrollView进行赋值
self.glt_scrollView = self.tableView（self.scrollView / self.collectionView）
- 更多使用说明请参考Demo（LTScrollView / Example）
OC使用说明
OC.LTSimple使用说明
- 创建LTSimpleManager实例对象
[[LTSimpleManager alloc] initWithFrame:frame viewControllers:self.viewControllers titles:self.titles currentViewController:self layout:self.layout]
- 设置headerView
[self.managerView configHeaderView:^UIView * _Nullable{ }]
- 子控制器中glt_scrollView进行赋值
self.glt_scrollView = self.tableView（self.scrollView / self.collectionView）
- 更多使用说明请参考Demo（LTScrollView / OCExample）
OC.LTAdvanced使用说明
- 创建LTAdvancedManager实例对象、并设置headerView
[[LTAdvancedManager alloc] initWithFrame:frame viewControllers:self.viewControllers titles:self.titles currentViewController:self layout:self.layout headerViewHandle:^UIView * _Nonnull{}]
- 子控制器中glt_scrollView进行赋值
self.glt_scrollView = self.tableView（self.scrollView / self.collectionView）
- 更多使用说明请参考Demo（LTScrollView / OCExample）

例如简单使用
