LEFrameworks

20170508 最新开发库LEUIMaker中已经整合了LEFrameworks的所有必要内容，并且对自动排版做了进一步升级，详见https://github.com/LarryEmerson/LEUIMaker （Layout、BottomTabbar、Hud、ListView、Popup、Segment、VC、QRCode） LEFrameworks不再更新维护。 LEUIMaker持续更新中...

Installation

LEFrameworks is available through CocoaPods. To install it, simply add the following line to your Podfile:

platform :ios, '7.0'
target "ProjectName” do 
pod "LEFrameworks"
end

导入头文件

 #import <LEFrameworks/LEFrameworks.h>

2016-10-18 推出 自动排版V2

特点：

1- 一行生成UI控件：view、UILabel、UIImageView、UIButton、UITextfield

2- 自动排版

3- 每行最后需要追加方法leAutoLayout，逻辑是根据之前的设置进行排版

gif演示：

LEBaseTableViewV2 优化列表滚动效果，大大增强滚动流畅性

16-09-07 在研究了开发者LiuWei（https://github.com/waynezxcv/LWAsyncDisplayView）的Gallop，主要是朋友圈模块后，顿然醒悟，原来Cell中的内容可以提前预加载并缓存，以空间换时间的概念，避免列表滚动过程中的计算，大大提高性能，列表滚动的流畅性。

能发现Gallop并非偶然，最近刚完成的项目中就有朋友圈模块。于是完成LEBaseTableViewV2立马开始优化工作。

优化工作非常简单，前提是列表继承LEBaseTableView：

1-替换原有的LEBaseTableView为LEBaseTableViewV2
2-对应的Cell继承类从LEBaseTableViewCell换成LEBaseTableViewDisplayCell，并且把-(void) leSetData:(id) data IndexPath:(NSIndexPath *) path换成-(void) leSetData:(id) data

当然如果列表Section>1，这种情况优化工作就不仅仅是替换这么简单了，得看列表具体情况。主要是复写tb的delegate及datasource。

Demo工程中首页右上角新增了一个switch，用于切换列表的加载方式，默认使用了LEBaseTableViewV2。具体优化效果，还需要真机测试，Cell越复杂对比越明显！

新增Demo工程于Example目录下，Demo的gif

关于库中导航栏处理说明：

	之前因为使用第三方库的原因不得不使用UINavigationController，从而表示之后不再自定义导航栏，但是后期发现系统导航栏自定义实在是不方便，同时考虑到界面跳转最合理的方式还是使用系统导航栏提供的push方式。现提出的方案是：应用导航栏隐藏，界面拉伸到全屏。导航栏处理则使用LEBaseNavigation来自定义。界面跳转则还是使用导航栏的push、pop方式。这样既可以自定义导航栏，也可以在特殊需求时使用系统导航栏，方式灵活。
	另外，目前为NSobject提供了一个隐式的方法leAdditionalInits，这个方法的定义是，凡是在初始化后需要做进一步初始化时统一使用这个方法。目前所有的View，凡是使用initWithAutoLayoutSettings初始化的都已经自动执行了该方法。

一、组件封装：

7-LEMultiImagePicker：图片多选组件（注意需要配合系统导航栏使用）

image

GIF中组件测试代码如下：

[self.navigationController setNavigationBarHidden:NO];
MultiImagePicker *picker=[[MultiImagePicker alloc] initWithImagePickerDelegate:self];
[self.navigationController pushViewController:picker animated:YES];

二、实用的自动排版的库的原理解析：（Demo中的onTestAutoLayout有所体现）

LEUIFramework，主要的用法是在新建视图时确定好其父视图，相对位置，大小后，之后父视图的变动，或者自身的变动无需花费大量监听代码去处理视图之间的关系。基本原理是子视图在初始化时，提供父视图、与父视图或者与其他子视图的相对位置、偏移量，大小（Label和Image可以设置为CGSizeZero，从而选择让库来自动处理大小）后，视图位置即可确定。当父视图或者相对位置的参考子视图有所变动时，子视图都会收到重排的指令，从而可以自动排版。而子视图在使用leSetOffset改变偏移量，leSetSize变动大小或者leSetFrame设置整个frame时，其他与之有相对位置关系的视图都会收到消息，从而所有视图都可以自动重排。

1）、所有的view在新建时都可以使用如下的3个初始化方法

-(id) initWithSuperView:(UIView *) superView Anchor:(LEAnchors) anchor Offset:(CGPoint) offset CGSize:(CGSize) size;相对位置参考物为父视图
-(id) initWithSuperView:(UIView *) superView Anchor:(LEAnchors) anchor RelativeView:(UIView *) relativeView Offset:(CGPoint) offset CGSize:(CGSize) size;

相对位置是父视图中的某一个子视图

-(id) initWithSuperView:(UIView *)superView EdgeInsects:(UIEdgeInsets) edge;

相对于父视图，子视图的大小为父视图的大小减去edge 2）、相对位置LEAnchors

锚点说明：（粗体红色矩形表示父视图）
1-蓝色字体部分表示参照视图为父视图的情况，使用九宫格的方式划分区域，因而共用9种停靠情况。
2-黑色字体部分表示参照视图为父视图中的某一同级子视图。有12中停靠点+4个对角线延伸线上，共16种情况。

image

3）、快速初始化组件（1句话初始化）：UILabel，UIImageView，UIButton

+(UIImageView *) leGetImageViewWithSettings:(LEAutoLayoutSettings *) settings Image:(UIImage *) image ;
+(UILabel *) leGetLabelWithSettings:(LEAutoLayoutSettings *) settings LabelSettings:(LEAutoLayoutLabelSettings *) labelSettings ;  
+(UIButton *) leGetButtonWithSettings:(LEAutoLayoutSettings *) settings ButtonSettings:(LEAutoLayoutUIButtonSettings *) buttonSettings ;

三、列表的封装：单组列表（LEBaseTableView） 见Demo工程中的 onTestLEBaseTableView

1）、已接入下拉刷新（leOnRefreshData），上拉加载更多（leOnLoadMore）的效果
2）、初始化简单- (id) initWithSettings:(LETableViewSettings *) settings; 
3）、列表数据源：
-(void) leOnRefreshedWithData:(NSMutableArray *)data;
-(void) leOnLoadedMoreWithData:(NSMutableArray *)data;
4）、初始化方法：参数有全屏视图，父视图，自定义Cell的类名，可自定义空列表Cell类名，列表数据源回调，列表Cell点击事件回调

-(id) initWithSuperViewContainer:(UIView *) superView ParentView:(UIView *) parent TableViewCell:(NSString *) cell EmptyTableViewCell:(NSString *) empty GetDataDelegate:(id<LETableViewDataSourceDelegate>) get TableViewCellSelectionDelegate:(id<LETableViewCellSelectionDelegate>) selection;
5）、可以重新自定义section及rows

四、Tabbar封装：LEBottomTabbar，LETabbarRelatedPageView

-(id) initTabbarWithFrame:(CGRect) frame Delegate:(id) delegate NormalIcons:(NSArray *) icons HighlightedIcons:(NSArray *) iconsSelected Titles:(NSArray *) titles Pages:(NSArray *) pages NormalColor:(UIColor *) normalColor HighlightedColor:(UIColor *) highlightedColor;

五、其他工具：

弹出消息（LELocalNotification）， 二维码扫码（LEScanQRCode）， 弹窗（LEPopup）、

七、其他 Version License Platform
