30 | }]; 31 | //更多数据源配置 32 | //[_dataSource setNumberOfRowsInSectionBlock:^NSUInteger(NSArray * data, NSInteger section) { 33 | // 34 | //}]; 35 | ``` 36 | 37 | ** 配置代理 ** 38 | 39 | ```objc 40 | //代理方法通过block实现 41 | [_delegate setSelectRowAtIndexPathBlock:^(id cell, NSIndexPath *indexPath) { 42 | NSString *controllerName = [NSString stringWithFormat:@"KCAutoHeightTableViewController%ld",indexPath.row + 1]; 43 | UIViewController *autoHeightController = [NSClassFromString(controllerName) new]; 44 | [weakSelf.navigationController pushViewController:autoHeightController animated:YES]; 45 | }]; 46 | //更多代理配置 47 | //[_delegate setHeightForRowAtIndexPathBlock:^CGFloat(NSIndexPath *indexPath) { 48 | // 49 | //}]; 50 | ``` 51 | 52 | ### 2. 自动计算Cell高度 53 | 从iOS 8开发人员才能利用"self-sizing cell"自动计算行高，但是这种方式似乎并没有iOS 7那么流畅，因为它会多次计算Cell高度，效率似乎并没有那么高。另外，目前不支持iOS 7还是不太现实的，或者说你还想要兼容更低版本。LightweightUITableView提供了一种更加通用和高效的解决方案。使用UITableView+KC 会让Cell行高计算更加方便（无论你是使用frame还是AutoLayout布局），再配合上KCTableViewDelegate这种实现则更加简洁，使用是直接配置UITableView的autoCellHeight为YES即可（当然建议配置estimatedRowHeight）。UITableView+KC内部会自动在空闲时间预计算Cell高度，并且自动维护行高不会多次计算行高。 54 | 在下面的实例中，仅仅通过几行代码即实现了Cell行高的计算。 55 | ```objc 56 | //如果使用KCTableViewDelegate只需要配置UITableView的autoCellHeight属性为YES即可（当然在定义Cell中需要实现height方法） 57 | self.tableView.estimatedRowHeight = 300.0; 58 | self.tableView.autoCellHeight = YES; 59 | self.dataSource.cellClass = [KCCardTableViewCell1 class]; 60 | self.data = [[KCPersonService requestPersons] mutableCopy]; 61 | [self.dataSource setCellBlock:^(KCCardTableViewCell1 *cell, id dataItem, NSIndexPath *indexPath) { 62 | cell.person = dataItem; 63 | }]; 64 | [self.delegate setWillDisplayCellBlock:^(UITableViewCell *cell, NSIndexPath *indexPath) { 65 | cell.seperatorPinToSupperviewMargins = YES;//分割线两端对齐 66 | }]; 67 | ``` 68 | ## 演示 69 | 70 | ![](https://github.com/kenshincui/LightweightUITableView/blob/master/LightweightUITableViewDemo/LightweightUITableViewDemo/Resources/AutoHeightCell.gif?raw=true) 71 | 72 | 73 | -------------------------------------------------------------------------------- /LightweightUITableViewDemo/LightweightUITableView/KCTableViewArrayDataSource.h: -------------------------------------------------------------------------------- 1 | // 2 | // KCTableViewArrayDataSource.h 3 | // KCFramework 4 | // 5 | // Created by Kenshin Cui on 15/2/2. 6 | // Copyright (c) 2015年 CMJStudio.
