原本项目页面不是由TableView构成,但是我用tableView比较适合,所以重写了一边,
项目源代码可以从我的gitHub https://github.com/vfanx/FreeLimit 上获得,这里我将tableView拆分成三部分
将DataSource和tableView分离,使其可以复用,抽象出部分接口使其可以定制
在这里,我一个创建了两个DataSource类,下面我贴出这个页面的DataSource类
1 #import <UIKit/UIKit.h> 2 #import "AppModel.h" 3 #import "XTableCellConfig.h" 4 5 @interface XDetailViewDataSource : NSObject<UITableViewDataSource,UITableViewDelegate> 6 7 - (instancetype)initWithTableView:(UITableView *)tableview 8 dataModel:(AppModel *)model 9 configureCellArry:(NSArray *)configureArry; 10 11 @end 12 13 14 15 #import "XDetailViewDataSource.h" 16 17 @interface XDetailViewDataSource () 18 19 @property (nonatomic,weak) UITableView *tableView; 20 @property (nonatomic,strong) AppModel *model; 21 @property (nonatomic,strong) NSArray *configureArry; 22 23 @end 24 25 @implementation XDetailViewDataSource 26 27 - (instancetype)initWithTableView:(UITableView *)tableview 28 dataModel:(AppModel *)model 29 configureCellArry:(NSArray *)configureArry 30 { 31 self = [super init]; 32 if (self) { 33 _tableView = tableview; 34 _configureArry = configureArry; 35 _model = model; 36 } 37 return self; 38 } 39 40 - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView 41 { 42 return _configureArry.count; 43 } 44 45 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 46 { 47 return [(NSArray *)_configureArry[section] count]; 48 } 49 50 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 51 { 52 XTableCellConfig *cellConfig = _configureArry[indexPath.section][indexPath.row]; 53 UITableViewCell *cell = nil; 54 cell = [cellConfig cellOfCellConfigWithTableView:tableView dataModel:_model isNib:YES]; 55 cell.selectionStyle = UITableViewCellSelectionStyleNone; 56 return cell; 57 } 58 59 - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath 60 { 61 XTableCellConfig *cellConfig = _configureArry[indexPath.section][indexPath.row]; 62 return cellConfig.heightOfCell; 63 } 64 65 - (NSString *)tableView:(UITableView *)tableView titleForFooterInSection:(NSInteger)section 66 { 67 return @" "; 68 } 69 70 @end
这个类存储着每个cell是怎么配置的
#import <UIKit/UIKit.h> @interface XTableCellConfig : NSObject @property (nonatomic, copy) NSString *className; @property (nonatomic, copy) NSString *title; @property (nonatomic, copy) void(^showInfoBlock)(id cell,id model); @property (nonatomic, assign) CGFloat heightOfCell; @property (nonatomic, strong) NSString *detail; @property (nonatomic, strong) NSString *remark; + (instancetype)cellConfigWithClassName:(NSString *)className title:(NSString *)title showInfoBlock:(void(^)(id cell,id model))showInfoMethod heightOfCell:(CGFloat)heightOfCell; - (UITableViewCell *)cellOfCellConfigWithTableView:(UITableView *)tableView dataModel:(id)dataModel; - (UITableViewCell *)cellOfCellConfigWithTableView:(UITableView *)tableView dataModel:(id)dataModel isNib:(BOOL)isNib; @end #import "XTableCellConfig.h" @implementation XTableCellConfig + (instancetype)cellConfigWithClassName:(NSString *)className title:(NSString *)title showInfoBlock:(void(^)(id cell,id model))showInfoBlock heightOfCell:(CGFloat)heightOfCell { XTableCellConfig *cellConfig = [XTableCellConfig new]; cellConfig.className = className; cellConfig.title = title; cellConfig.showInfoBlock = showInfoBlock; cellConfig.heightOfCell = heightOfCell; return cellConfig; } - (UITableViewCell *)cellOfCellConfigWithTableView:(UITableView *)tableView dataModel:(id)dataModel { return [self cellOfCellConfigWithTableView:tableView dataModel:dataModel isNib:NO]; } - (UITableViewCell *)cellOfCellConfigWithTableView:(UITableView *)tableView dataModel:(id)dataModel isNib:(BOOL)isNib { Class cellClass = NSClassFromString(self.className); NSString *cellID = self.className; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellID]; if (!cell) { if (isNib) { NSArray *nibs = [[NSBundle mainBundle] loadNibNamed:self.className owner:nil options:nil]; cell = [nibs lastObject]; } else { cell = [[cellClass alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:cellID]; } } if (self.showInfoBlock) { _showInfoBlock(cell,dataModel); } return cell; } @end
创建Datasource,cellConfigure,并与其关联即可

[ale show]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } @end
语言组织能力不太好,所以能用代码表达的,就比较少打字表达,上面使用到的方法,可以极大的提高代码的复用性;
具体可以参考github上的完整代码,写这篇博文时项目没有完成,也不知道什么时候完成,但是已经是现实上述方法.
