前言：偷个懒，这篇文章写起来有些绕，还要修改做好的数据之类的，所以大概只写个思路，代码不用看的太过相信！
零、核心代码和思路
1. 在控制器创建 commentView，然后赋值Model，在commentView.m中 setModel重新初始化，并赋值使用；
2.评论功能分为 评论tableview 和 回复tableview；
3.在重新初始化 setModel set方法中，获取评论条数和model，根据评论内容计算出文本高度，然后重设评论tableview高度；
4.在评论tableview 的 cellForRowAtIndexPath 方法里，获取回复内容的条数和model，然后根据回复内容计算出文本高度，然后用 cell的方法赋值到回复tableview中，刷新列表，代码：
1）MSUVideoDetailCommentView中代码
// 计算回复table 高度
CGFloat tableViewHeight = 0.0;
if (arrModel.reply.count > 0) {
for (NSInteger i = 0; i < arrModel xss=removed> 0) {
str = [NSString stringWithFormat:@"%@ 回复 %@：%@",commentModel.from_user,commentModel.to_user,commentModel.content];;
}else {
str = [NSString stringWithFormat:@"%@：%@",commentModel.from_user,commentModel.content];
}
CGRect comnmentRect = [MSUStringTools danamicGetHeightFromText:str WithWidth:SelfWidth-28-36-5-20 font:10];
tableViewHeight = tableViewHeight + comnmentRect.size.height + 5;
}
} else{
tableViewHeight = -15;
}
// 加上头部视图和底部试图
[cell configCellWithModel:arrModel tableHeight:tableViewHeight+15];
cell.lineView.frame = CGRectMake(55, CGRectGetMaxY(cell.commentLab.frame)+5+tableViewHeight+15+10-1, SelfWidth-55-14, 1);
2） MSUVideoCommentTableCell 中代码
- (void)configCellWithModel:(MSUArrModel *)model tableHeight:(NSInteger)height{
self.arrModel = model;
// 重设 回复table高度
[_commentTableView remakeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(_commentLab.bottom).offset(5);
make.left.equalTo(_commentLab.left).offset(0);
make.width.equalTo(CommentTableWidth);
make.height.equalTo(height);
}];
[self.commentTableView reloadData];
}
5. 回复tableview 中 回复内容颜色是富文本设置，代码：
if (commentModel.to_user.length > 0) {
// 富文本设置
NSString *str = [NSString stringWithFormat:@"%@ 回复 %@：%@",commentModel.from_user,commentModel.to_user,commentModel.content];;
NSMutableAttributedString *att = [MSUStringTools makeKeyWordAttributedWithSubText:commentModel.to_user inOrigiText:str font:10 color:HEXCOLOR(0xf49418)];
cell.commentLab.attributedText = [MSUStringTools makeAttrubuteKeyWordAttributedWithSubText:commentModel.from_user inOrigiText:att font:10 color:HEXCOLOR(0xf49418)];
}else {
// 富文本设置
NSString *str = [NSString stringWithFormat:@"%@：%@",commentModel.from_user,commentModel.content];
cell.commentLab.attributedText = [MSUStringTools makeKeyWordAttributedWithSubText:commentModel.from_user inOrigiText:str font:10 color:HEXCOLOR(0xf49418)];
}
6.评论view的整体高度回调，在评论tableview 中的 setModel方法中，遍历 评论条数和model 以及 回复条数和model，计算出内容高度， 然后回调给控制器 中的scrollview 的contentSize，代码：
MSUVideoDetailCommentView中：
- (void)setDataModel:(MSUDataDetailModel *)dataModel{
_dataModel = dataModel;
if (_dataModel.comments.count > 0) {
self.titLab.text = [NSString stringWithFormat:@"评论（%ld）",_dataModel.comments.count];
self.comeLab.hidden = YES;
self.tableView.hidden = NO;
} else{
self.titLab.text = @"评论";
self.tableView.hidden = YES;
self.comeLab.hidden = NO;
}
CGFloat height = 0.0;
for (NSInteger i = 0; i < _dataModel.comments.count; i++) {
MSUArrModel *arrModel = _dataModel.comments[i];
// 计算评论内容高度
CGRect rect = [MSUStringTools danamicGetHeightFromText:arrModel.content WithWidth:SelfWidth-65-14 font:11];
// 计算回复table高度
CGFloat tableViewHeight = 0.0;
for (NSInteger i = 0; i < arrModel.reply.count; i++) {
MSUCommentModel *commentModel = arrModel.reply[i];
NSString *str;
if (commentModel.to_user.length > 0) {
str = [NSString stringWithFormat:@"%@ 回复 %@：%@",commentModel.from_user,commentModel.to_user,commentModel.content];;
}else {
str = [NSString stringWithFormat:@"%@：%@",commentModel.from_user,commentModel.content];
}
CGRect comnmentRect = [MSUStringTools danamicGetHeightFromText:str WithWidth:SelfWidth-28-36-5-20 font:10];
tableViewHeight = tableViewHeight + comnmentRect.size.height + 5;
}
// 计算评论table高度
height = height + 28 + rect.size.height + 5 + tableViewHeight + 15 + 10;
}
// 重设评论table高度
[_tableView remakeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self.top).offset(35);
make.left.equalTo(self.left).offset(0);
make.width.equalTo(SelfWidth);
make.height.equalTo(height);
}];
[self.tableView reloadData];
if (self.tableHeightBlock) {
self.tableHeightBlock(height);
}
}
控制器中 ：
__weak typeof(self) weakSelf = self;
_comment.tableHeightBlock = ^(NSInteger height) {
// 更改滚动视图的滚动面积
weakSelf.bgScrollView.contentSize = CGSizeMake(0, 10+self.videoHeight+5+130+height+45);
// 更改评论父视图的frame
CGRect frame = weakSelf.comment.frame;
frame.size.height = 10+self.videoHeight+5+130+height;
weakSelf.comment.frame = frame;
};
一、模型 MSUVideoDetailModel （因为做的是视频、商品，然后下面有评论，所以model内容较多，MSUArrModel和MSUCommentModel是评论的数据结构，其他的可以忽视）
1.MSUVideoDetailModel.h中的代码

@end
2.MSUVideoDetailModel.m中的代码
#import "MSUVideoDetailModel.h"
@implementation MSUVideoDetailModel
+ (NSDictionary *)mj_objectClassInArray{
return @{@"data":[MSUDataDetailModel class]};
}
@end
@implementation MSUDataDetailModel
+ (NSDictionary *)mj_objectClassInArray{
return @{@"video":[MSUDetailVideoModel class],
@"goods":[MSUDetailGoodsModel class],
@"comments":[MSUArrModel class]};
}
@end
#pragma makr - 视频
@implementation MSUDetailVideoModel
+ (NSDictionary *)mj_objectClassInArray{
return @{@"sign":[MSUSignDetailModel class]};
}
@end
@implementation MSUSignDetailModel
@end
#pragma makr - 商品
@implementation MSUDetailGoodsModel
@end
#pragma makr - 评论
@implementation MSUCommentModel
@end
@implementation MSUArrModel
+ (NSDictionary *)mj_objectClassInArray{
return @{@"reply":[MSUCommentModel class]};
}
@end
二、评论的核心结构就是 tableview 嵌套 tableview ，所以，新建一个View 集成UIView MSUVideoDetailCommentView
1. MSUVideoDetailCommentView.h 中的代码
#import <UIKit>
#import "MSUVideoDetailModel.h"
@protocol MSUVideoDetailCommentViewDelegate <NSObject>
- (void)pinglunCellDidSelectWithUid:(NSString *)uid commentID:(NSString *)commentID topId:(NSString *)topID;
@end
@interface MSUVideoDetailCommentView : UIView
@property (nonatomic , weak) id<MSUVideoDetailCommentViewDelegate> delegate;
/// 回调table高度
@property (nonatomic , copy)void(^tableHeightBlock)(NSInteger height);
/// 评论标题
@property (nonatomic , strong) UILabel *titLab;
/// 内容
@property (nonatomic , strong) UITableView *tableView;
/// 无内容视图
@property (nonatomic , strong) UILabel * comeLab;
/// 数据
@property (nonatomic , strong) MSUDataDetailModel *dataModel;
/// 行高
@property (nonatomic , assign) CGFloat cellHeight;
@end
2. MSUVideoDetailCommentView.m 中的代码 （MSUPathTools.h 是我封装的路径类，MSUStringTools.h是封装的string相关类，在这个地方用以获取文本高度，MSUAFNRequest.h是网络请求类，MSUHUD.h是弹窗类，可根据自己封装类使用）
#import "MSUVideoDetailCommentView.h"
#import "UIButton+WebCache.h"
#import "MSUPathTools.h"
#import "MSUStringTools.h"
#import "MSUAFNRequest.h"
#import "MSUHUD.h"
#define WIDTH [UIScreen mainScreen].bounds.size.width
#define SelfWidth [UIScreen mainScreen].bounds.size.width
//masonry
#define MAS_SHORTHAND
#define MAS_SHORTHAND_GLOBALS
#import "Masonry.h"
#define HEXCOLOR(rgbValue) [UIColor colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 green:((float)((rgbValue & 0xFF00) >> 8))/255.0 blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]
