KJSupportObjc 是在iOS平台集常用分类、工具、异常处理、和自定义UITableView封装UITableView及常见的Cell套件为一体的一个常用轻量级的库，适用于所有iOS开发者，包括Objective-C和Swift
- 直接把KJSupportObjcLib文件夹下的所有文件拖入项目
- 使用CocoaPods导入下面几个库
- Masonry
- ActionSheetPicker-3.0
- SDWebImage
传统情况下，项目里很多控制器都会使用到UITableView，而且每个控制器要注册不同的Cell，实现
- registerNib:forCellReuseIdentifier:
- registerClass:forCellReuseIdentifier:
- numberOfSectionsInTableView:
- tableView:numberOfRowsInSection:
- tableView:cellForRowAtIndexPath:
- tableView:heightForRowAtIndexPath:
- tableView:heightForHeaderInSection:
- tableView:heightForFooterInSection:
- tableView:didSelectRowAtIndexPath:
几乎每一个用到UITableView的地方都要重复的写上面几行代码，这样传统的方式存在下面一些问题
- 每个用到UITableView的地方都要重复注册Cell和实现上面几行代码，以及维护数据源和UITableView匹配关系
- 对于UITableView里面有多重不同类型的Cell，处理Cell上显示的数据和Cell不等高，区头、区尾高度或者标题，稍有不慎，如果匹配不上，就会导致崩溃
- 我的界面和设置界面里常见的一些Cell（比如左边一个图片和标题、右边一个文字和箭头）在别的用到UITableView的地方又要重新写和注册等操作
- 在一些控制器里，某些情况下需要隐藏若干个Cell，然后在另一种情况下又要显示这几个Cell，在传统的代码实现上，处理麻烦而且很难跨越项目统一处理
- 在一些时候需要对UITableView增加删除移动等操作，数据源处理不好，容易崩溃

上面这样一个示例，你会清晰的发现，当一个UITableView里面有多种类型的情况时，这代码已经变得难以阅读你也很难很好的掌握这几个协议方法之间匹配关系了，上面的示例仅仅是在一个UITableView里面，往往公司的项目都很庞大，使用UITableView地方特别多，使用传统的方式不仅仅要写很多重复的代码，枯燥无味，而且项目也很难维护，下面是CKJSimpleTableView解决这样的问题的方式。
这是CKJSimpleTableView的写法
- (nonnull NSDictionary <NSString *, NSDictionary <NSString *, id>*> *)returnCell_Model_keyValues:(CKJSimpleTableView *_Nonnull)s {
return @{
NSStringFromClass([RJDepartmentImageCellModel class]) : @{KJPrefix_cellKEY : NSStringFromClass([RJDepartmentImageCell class]), KJPrefix_isRegisterNibKEY : @YES},
NSStringFromClass([RJSchedule_DoctorCellModel class]) : @{KJPrefix_cellKEY : NSStringFromClass([RJSchedule_DoctorCell class]), KJPrefix_isRegisterNibKEY : @YES},
NSStringFromClass([RJSchedule_IntroductionCellModel class]) : @{KJPrefix_cellKEY : NSStringFromClass([RJSchedule_IntroductionCell class]), KJPrefix_isRegisterNibKEY : @YES},
NSStringFromClass([RJSchedule_DateCellModel class]) : @{KJPrefix_cellKEY : NSStringFromClass([RJSchedule_DateCell class]), KJPrefix_isRegisterNibKEY : @YES},
NSStringFromClass([RJSchedule_DetailTitleCellModel class]) : @{KJPrefix_cellKEY : NSStringFromClass([RJSchedule_DetailTitleCell class]), KJPrefix_isRegisterNibKEY : @NO}
};
}
- (void)initSimpleTableViewData {
KJ_typeweakself
CKJCommonSectionModel *section1 = [CKJCommonSectionModel sectionWithDetail:^(__kindof CKJCommonSectionModel * _Nonnull _sec) {
RJSchedule_DoctorCellModel *model1 = [RJSchedule_DoctorCellModel modelWithCellHeight:70 cellModel_id:nil detailSettingBlock:^(RJSchedule_DoctorCellModel * _Nonnull m) {
m.doctModel = _doctModel;
} didSelectRowBlock:nil];
RJDepartmentImageCellModel *model2 = [RJDepartmentImageCellModel modelWithCellHeight:120 cellModel_id:nil detailSettingBlock:^(__kindof RJDepartmentImageCellModel * _Nonnull m) {
m.dep = _deptModel.HisDeptName;
} didSelectRowBlock:nil];
RJSchedule_IntroductionCellModel *model3 = [RJSchedule_IntroductionCellModel modelWithCellHeight:0 cellModel_id:nil detailSettingBlock:^(__kindof RJSchedule_IntroductionCellModel * _Nonnull m) {
m.text = self.category.type > 1 ? _doctModel.Profession : _deptModel.Description;
} didSelectRowBlock:nil];
_sec.modelArray = @[model1, model2, model3];
}];
CKJCommonSectionModel *section2 = [CKJCommonSectionModel sectionWithHeaderHeight:10 detailSetting:^(__kindof CKJCommonSectionModel * _Nonnull _sec) {
RJSchedule_DetailTitleCellModel *model1 = [RJSchedule_DetailTitleCellModel modelWithCellHeight:40 cellModel_id:nil detailSettingBlock:nil didSelectRowBlock:nil];
RJSchedule_DateCellModel *model2 = [RJSchedule_DateCellModel modelWithCellHeight:60 cellModel_id:@(kCollectionDateCell) detailSettingBlock:^(__kindof RJSchedule_DateCellModel * __weak _Nonnull m) {
m.selectedDateBlock = ^(NSInteger index, NSString *dateStr, NSString *weekStr) {
NSLog(@"点击 某一天");
};
} didSelectRowBlock:nil];
_sec.modelArray = @[model1, model2];
}];
self.simpleTableView.dataArr = @[section1, section2];
}你可以只需要创建CKJCommonSectionModel分区对象和CKJCommonCellModel每一行CellModel的子对象，用CKJSimpleTableViewDataSource、CKJSimpleTableViewDelegate代替系统的UITableViewDataSource、UITableViewDelegate方法，此刻你只需要管理数据即可，不需要担心CKJSimpleTableView数据匹配不上导致的闪退问题
你会发现现在设置区头区尾高度和标题会变得非常方便
@interface CKJCommonSectionModel : CKJSimpleBaseModel
// 设置区头、区尾高度
+ (instancetype)sectionWithHeaderHeight:(NSNumber *_Nullable)headerHeight footerHeight:(NSNumber *_Nullable)footerHeight detailSetting:(CKJSectionBlock _Nullable)detailSetting;
// 设置区头、区尾标题
+ (instancetype)sectionWithHeaderAttString:(NSAttributedString *_Nullable)headerAttString headerAlignment:(NSTextAlignment)headerAlignment footerAttString:(NSAttributedString *_Nullable)footerAttString footerAlignment:(NSTextAlignment)footerAlignment detailSetting:(CKJSectionBlock _Nullable)detailSetting;
......
@end自适应高度 和 固定高度
@interface CKJCommonCellModel : CKJSimpleBaseModel
// 行高，依次看CKJCommonCellModel.cellHeight，CKJCommonSectionModel.rowHeight，CKJSimpleTableViewStyle.rowHeight的值，如果都为nil，最后自适应高度，也可以设置UITableViewAutomaticDimension
@property (copy, nonatomic, nullable) NSNumber *cellHeight;
// 标记, 每一个CellModel的cellModel_id 一定不能相同
@property (copy, nonatomic, nullable) NSString *cellModel_id;
// 是否在UITableView里面显示
@property (assign, nonatomic) BOOL displayInTableView;
// 点击某一行时候回调
@property (copy, nonatomic, nullable) CKJCommonCellModelRowBlock didSelectRowBlock;
// 背景设置
- (void)updateBGConfig:(void(^_Nullable)(CKJCommonCellBGImageViewConfig *bg))BGConfig;
// 设置分割线是否显示
- (void)_showLine:(BOOL)show;
......
@end在指定Cell的后面插入Cells数组（可使用动画）
- kjwd_insertCellModelsInAllCellModel:afterCellModel:
- kjwd_insertCellModelsInAllCellModel:afterCellModel:withRowAnimation:animationBlock:
在指定分区的末尾拼接Cells数组（可使用动画）
- appendCellModelArray:atLastRow_InAllCellModelArrayOfSection:
- appendCellModelArray:atLastRow_InAllCellModelArrayOfSection:withRowAnimation:animationBlock:
删除模型在某个分区的某一行（可使用动画）
- removeCellModelAtSection:rows:removeHiddenCellModel:
- removeCellModelAtSection:rows:removeHiddenCellModel:withRowAnimation:animationBlock:
删除模型在某个分区除了指定行的全有行，只保留指定行（可使用动画）
- removeAllCellModelAtSection:keepDisplayRows:removeHiddenCellModel:
- removeAllCellModelAtSection:keepDisplayRows:removeHiddenCellModel:withRowAnimation:animationBlock:
删除某个分区（可使用动画）
- removeSections:
- removeSections:withRowAnimation:animationBlock:
删除全部分区，只保留指定分区（可使用动画）
- removeAllSection_notIncludedSection:
- removeAllSection_notIncludedSection:withRowAnimation:animationBlock:
和插入一样的写法

@end
效果如下
开发者只需管理好数据模型，UI全部根据数据模型进行渲染，如果想要修改UI的数据，只需要找到其数据模型，修改数据模型的数据，UI会自动改变。有些核心Cell需要设置配置数据，有些可以直接进行使用。比如上面示例中， CKJImageLeftCell则需要设置配置数据，而CKJGeneralCell和CKJTableViewCell1则不需要。
对于封装好的核心Cell，省去了开发者在不同的界面里重复的布局Cell带来的麻烦，可以提高开发效率节约开发时间。
KJSupportObjc库提供了iOS最常用的分类，包括NSArray、NSMutableArray、NSDictionary、NSString、NSDate、UIView、UIButton、UIColor、UIImage、UIViewController等。
KJSupportObjc库对系统的类做了很多异常处理，在异常的情况下给出友好的提示。
