具體自定義cell的代碼

#import <UIKit/UIKit.h> @class getCommentData; @interface commentCell : UITableViewCell @property(nonatomic,strong)getCommentData *commentData; @property(nonatomic,strong)UILabel *nameLabel; @property(nonatomic,strong)UILabel *titleLabel; @property(nonatomic,strong)UILabel *dateLabel; @end #import "commentCell.h" #import "commentsModel.h" @implementation commentCell-(void)setCommentData:(getCommentData *)commentData{_commentData=commentData;_titleLabel.text=commentData.message;_dateLabel.text=commentData.createTimeStr;_nameLabel.text=commentData.nickName;}- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];if (self) {[self setup];}return self; }-(void)setup{_nameLabel=[UILabel new];[self.contentView addSubview:_nameLabel];_nameLabel.textColor=[UIColor colorWithRed:0.891 green:0.549 blue:0.073 alpha:1.000];_nameLabel.font=[UIFont systemFontOfSize:15];_nameLabel.numberOfLines=1;_titleLabel=[UILabel new];[self.contentView addSubview:_titleLabel];_titleLabel.textColor=[UIColor darkGrayColor];_titleLabel.font=[UIFont systemFontOfSize:15];_titleLabel.numberOfLines=0;_dateLabel=[UILabel new];[self.contentView addSubview:_dateLabel];_dateLabel.textColor=[UIColor colorWithRed:0.679 green:0.166 blue:0.828 alpha:1.000];_dateLabel.font=[UIFont systemFontOfSize:15];_dateLabel.numberOfLines=1;CGFloat margin=10;UIView *contentView=self.contentView;_nameLabel.sd_layout.leftSpaceToView(contentView,margin).topSpaceToView(contentView,margin).rightSpaceToView(contentView,margin).heightIs(20);_titleLabel.sd_layout.leftSpaceToView(contentView,margin).topSpaceToView(_nameLabel,2).rightSpaceToView(contentView,margin).autoHeightRatio(0);_dateLabel.sd_layout.leftSpaceToView(contentView,margin).topSpaceToView(_titleLabel,5).heightIs(20).widthIs(150);[self setupAutoHeightWithBottomViewsArray:@[_titleLabel,_dateLabel,_nameLabel] bottomMargin:margin]; }- (void)awakeFromNib { }- (void)setSelected:(BOOL)selected animated:(BOOL)animated {[super setSelected:selected animated:animated];}@end
