开发中封装的框架

01-BNVCContainer

继承
	xx : BNVCContainer
重写数组
	- (NSArray<BNCToolbarItem *> *)items {
添加子控制器
	[self addController:vc];
	有需要updateRootView的位置

02-CommonCell

快速构建个人页

03-CheckBox

勾选同意

04-AlertController

封装弹窗提示

05-MGNaVBackBarButtonItem

统一设置导航控制器的返回按钮，modal和push模式

控制器继承MGBaseViewController即可
- 首页的leftBarButtonItem不用设置
- 不用设置push控制器和modal出来控制的返回leftBarButtonItem
- 统一设置能处理2种情况的返回

06-MGPlaceholderTextView

用label实现占位文字的textView，可修改颜色，字体

// 添加一个MGPlaceholderTextView
MGPlaceholderTextView *textView = [[MGPlaceholderTextView alloc] init];
textView.frame = self.view.bounds;
textView.placeholder = @"这是一段占位文字………这是一段占位文字………这是一段占位文字………";
[self.view addSubview:textView];

07-流水线性布局

简书collectionView流水线性布局(自定义)

X-Waterflow

瀑布流框架，不常用

@class MGWaterflowLayout;

@protocol MGWaterflowLayoutDelegate <NSObject>
@required
- (CGFloat)waterflowLayout:(MGWaterflowLayout *)waterflowLayout heightForItemAtIndex:(NSUInteger)index itemWidth:(CGFloat)itemWidth;

@optional
- (NSInteger)columnCountInWaterflowLayout:(MGWaterflowLayout *)waterflowLayout;
- (CGFloat)columnMarginInWaterflowLayout:(MGWaterflowLayout *)waterflowLayout;
- (CGFloat)rowMarginInWaterflowLayout:(MGWaterflowLayout *)waterflowLayout;
- (UIEdgeInsets)edgeInsetsInWaterflowLayout:(MGWaterflowLayout *)waterflowLayout;
@end

@interface MGWaterflowLayout : UICollectionViewLayout
/** 代理 */
@property (nonatomic, weak) id<MGWaterflowLayoutDelegate> delegate;
