直接上代碼：

1：先自定義cell

.h文件中

#import <UIKit/UIKit.h> #import "LBDNewMsgListModel.h" #import "MLEmojiLabel.h"@interface LBDMsgCenterCell : UITableViewCell<MLEmojiLabelDelegate, UIGestureRecognizerDelegate>@property (nonatomic, strong) UILabel *msgDateLbl; @property (nonatomic, strong) UIView *bgView; @property (nonatomic, strong) UIView *topLineView; @property (nonatomic, strong) UIImageView *msgImgView; @property (nonatomic, strong) UILabel *titleLbl; @property (nonatomic, strong) UILabel *orderNum; @property (nonatomic, strong) UIView *lineView; @property (nonatomic, strong) UILabel *lookLbl; @property (nonatomic, strong) MLEmojiLabel *contentLbl;@property (nonatomic, strong) LBDNewMsgListModel *model;@end

.m文件中

2：在控制器.m文件中使用

- (void)drawView {_tableView = [[UITableView alloc] initWithFrame:CGRectZero style:UITableViewStylePlain];_tableView.backgroundColor = [UIColor bgColor];_tableView.separatorStyle = UITableViewCellSeparatorStyleNone;_tableView.delegate = self;_tableView.dataSource = self;[self addSubview:_tableView];// 給一個標識符，告訴tableView要創建哪個類[_tableView registerClass:[LBDMsgCenterCell class] forCellReuseIdentifier:@"LBDMsgCenterCell"];}- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {return [self.tableView fd_heightForCellWithIdentifier:@"LBDMsgCenterCell" cacheByIndexPath:indexPath configuration:^(LBDMsgCenterCell *cell) {// 在這個block中，重新cell配置數據源 [self setupModelOfCell:cell atIndexPath:indexPath];}]; }- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {return _msgArr.count; }- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {LBDMsgCenterCell *cell = [tableView dequeueReusableCellWithIdentifier:@"LBDMsgCenterCell"];cell.selectionStyle = UITableViewCellSelectionStyleNone;cell.backgroundColor = [UIColor clearColor];[self setupModelOfCell:cell atIndexPath:indexPath];return cell; }- (void)setupModelOfCell:(LBDMsgCenterCell *) cell atIndexPath:(NSIndexPath *) indexPath {// 采用計算frame模式還是自動布局模式，默認為NO，自動布局模式// cell.fd_enforceFrameLayout = NO;cell.model = _msgArr[indexPath.row]; }
