1.cell

@interface QPStatusCell ()

/** 图像 */
@property (nonatomic, weak)IBOutlet UIImageView *iconImageView;
/** 昵称 */
@property (nonatomic, weak)IBOutlet UILabel *nameLabel;
/** vip */
@property (nonatomic, weak)IBOutlet UIImageView *vipImageView;
/** 正文 */
@property (nonatomic, weak)IBOutlet UILabel *text_Label;
/** 配图 */
@property (nonatomic, weak)IBOutlet UIImageView *pictureImageView;
@property (weak, nonatomic) IBOutlet NSLayoutConstraint *pitureHeight;
@property (weak, nonatomic) IBOutlet NSLayoutConstraint *pictureBottom;

@end

@implementation QPStatusCell


/**
 *  设置子控件的数据
 */
- (void)setStatus:(XMGStatus *)status
{
    _status = status;
    self.iconImageView.image = [UIImage imageNamed:status.icon];
    self.nameLabel.text = status.name;
    
    if (status.isVip) {
        self.nameLabel.textColor = [UIColor orangeColor];
        self.vipImageView.hidden = NO;
    } else {
        self.vipImageView.hidden = YES;
        self.nameLabel.textColor = [UIColor blackColor];
    }
    
    self.text_Label.text = status.text;
    
    if (status.picture) { // 有配图
        self.pictureImageView.hidden = NO;
        self.pictureImageView.image = [UIImage imageNamed:status.picture];
        self.pitureHeight.constant = 100;
        self.pictureBottom.constant = 10;
    } else { // 无配图
        self.pictureImageView.hidden = YES;
        self.pitureHeight.constant = 0;
        self.pictureBottom.constant = 0;
    }
}

@end

2.UITableViewController

@interface ViewController ()

/** 所有的微博数据 */
@property (nonatomic, strong) NSArray *statuses;
@end

@implementation ViewController

- (NSArray *)statuses
{
   if (!_statuses) {
       _statuses = [QPStatus mj_objectArrayWithFilename:@"statuses.plist"];
   }
   return _statuses;
}


- (void)viewDidLoad {
   [super viewDidLoad];
   
   // self-sizing(iOS8 以后)
   // 告诉tableView所有cell的真实高度是自动计算的(根据设置的约束)
   self.tableView.rowHeight = UITableViewAutomaticDimension;
   // 设置估算高度
   self.tableView.estimatedRowHeight = 44;
}

#pragma mark - 数据源方法
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
   return self.statuses.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
   static NSString *ID = @"status";
   // 访问缓存池
   QPStatusCell *cell = [tableView dequeueReusableCellWithIdentifier:ID];
   
   // 传递模型数据
   cell.status = self.statuses[indexPath.row];
   return cell;
}
