難點：由于有視頻，語音搅幅，地理位置阅束，文字，圖片等不同的數(shù)據(jù)類型茄唐，所以相對來說布局叫復(fù)雜
主要的思路是：在獲取數(shù)據(jù)的同時息裸，計算好每個cell的布局，高度
1.數(shù)據(jù)類
@interface ShareInfoDemo : NSObject
@property(nonatomic,strong)NSString *idNum;
@property(nonatomic,strong)NSString *type;
@property(nonatomic,strong)NSString *content;
@property(nonatomic,strong)NSArray? *referUris;
@property(nonatomic,strong)NSString *duration;
@property(nonatomic,strong)NSString *sendTime;
@property(nonatomic,strong)SelfDataModel *user;
@property(nonatomic,strong)NSMutableDictionary *replyPage;
@property(nonatomic,strong)NSMutableDictionary *zans;
@property(nonatomic,strong)NSString *location;
@property(nonatomic,assign)bool hasShowAll;
@end
2.計算每個cell
@interface ShareInfoFrame : NSObject
@property(nonatomic,strong)ShareInfoDemo *shareInfo;
@property(nonatomic,assign)CGRect iconImageFrame;
@property(nonatomic,assign)CGRect nameFrame;
@property(nonatomic,assign)CGRect contentFrame;
@property(nonatomic,strong)NSMutableArray * imageViewFArr;
@property(nonatomic,assign)CGRect mapFrame;
@property(nonatomic,assign)CGRect playviewFrame;
@property(nonatomic,assign)CGRect timeFrame;
@property(nonatomic,assign)CGRect blogToolBarF;
@property(nonatomic,strong)NSMutableArray *responseViewHeightArr;
@property(nonatomic,assign)CGFloat cellHeight;
@property(nonatomic,assign)CGRect zanFrame;
@property(nonatomic,assign)CGRect playSoundFrame;
@property(nonatomic,assign)CGRect delectFrame;
@property(nonatomic,assign)CGRect showAllFrame;
@end
