IOS -- 纯代码实现tableview

1.HMBookListenTimingView.h  添加

#import "NSObject+HMCategory.h"

<UITableViewDelegate,UITableViewDataSource>

 

self.tableview = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, SCREEN_W, rect.size.height-60) style:UITableViewStylePlain];
    self.tableview.scrollEnabled = NO;
    self.tableview.backgroundColor = [UIColor clearColor];
    self.tableview.alpha = 0.9;
    self.tableview.separatorStyle = UITableViewCellSeparatorStyleSingleLine;
    self.tableview.separatorInset = UIEdgeInsetsMake(0, 20, 0, 20);
    [_tableview registerClass:[HMBookListenTimingViewCell class] forCellReuseIdentifier:[HMBookListenTimingViewCell hm_className]];
    _tableview.delegate = self;
    _tableview.dataSource = self;
    [self addSubview:_tableview];

协议方法

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    
    HMBookListenTimingViewCell *cell = [tableView dequeueReusableCellWithIdentifier:[HMBookListenTimingViewCell hm_className] forIndexPath:indexPath];
    
    _currentSelectTimingModel = _timeListenData[indexPath.row];
    cell.leftLable.text = _currentSelectTimingModel.title;
    
    if (indexPath.row == self.timeListenData.count - 1) {
        [tableView selectRowAtIndexPath:indexPath animated:YES scrollPosition:UITableViewScrollPositionNone];
    }
    return cell;
}

2.HMBookListenTimingViewCell.h

#import <UIKit/UIKit.h>
#import "HMBookListenTimingManager.h"

@interface HMBookListenTimingViewCell : UITableViewCell

@property (nonatomic, strong)  UILabel *leftLable;                  //左边标题
@property (nonatomic, strong)  UILabel *countDownLable;             //剩下的时间
@property (nonatomic, strong)  UIImageView *chooseImageView;        //选择图片

@end

#import "HMBookListenTimingViewCell.h"
#import <Masonry.h>
