前言：
最近在做cell自适应，并且高度缓存,我在简书上找了许多学习文章，也请教了简书上大佬们，感谢他们的指导，现在我终于实现了微博的简单布局。
附上学习文章：
看效果：
引用了几个框架了解一下：
1.Masonry (布局)
2.FDTemplateLayoutCell （sunny大大的开源框架 牛逼！）已经有一年多没更新了....
3.PYPhotoBrowser（图片浏览器）就这个新的图片浏览器框架还在维护着，但是不支持最新的SDWebImage.，只支持4.2.
好了，咋们开始学习一下吧.
根据FDTemplateLayoutCell框架要求，把控件都要添加到contentView上,并且自上而下对控件进行约束，要求上左下右至少有一个约束,具体的就去看阳神的源代码.
但是因为我把添加到cell里面的子控件都抽取到一个自定义的view里，所以下面子控件都添加到自定义View上
UIImageView*icon = [[UIImageView alloc] init];
icon.backgroundColor = [UIColor redColor];
icon.layer.cornerRadius = 25;
icon.layer.masksToBounds = YES;
self.icon= icon;
[self addSubview:self.icon];
UILabel*name = [[UILabel alloc] init];
self.name= name;
[self addSubview:self.name];
UILabel*time = [[UILabel alloc] init];
time.font = [UIFont systemFontOfSize:14];
self.time= time;
[self addSubview:self.time];
UIImageView *line = [[UIImageView alloc] init];
line.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.1];
[selfaddSubview:line];
UILabel *conText = [[UILabel alloc] init];
conText.preferredMaxLayoutWidth = SCREEN_W - 40;;
conText.numberOfLines=0;
conText.font = [UIFont systemFontOfSize:16];
self.ConText= conText;
[self addSubview:self.ConText];
PYPhotosView *flowphone = [PYPhotosView photosView];
self.pyphotosView= flowphone;
[self addSubview:self.pyphotosView];
#pragma mark -约束
[self.icon mas_makeConstraints:^(MASConstraintMaker *make) {
make.left.equalTo(self).offset(15);
make.top.equalTo(self).offset(10);
make.height.and.width.mas_equalTo(50);
}];
[self.name mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self).offset(15);
make.left.equalTo(self.icon.mas_right).offset(13);
}];
[self.time mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self.name.mas_bottom).offset(10);
make.left.equalTo(self.icon.mas_right).offset(10);
}];
[linemas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self.icon.mas_bottom).offset(10);
make.left.equalTo(self.icon).priority(900);
make.right.equalTo(self).offset(-15).priority(900);
make.height.mas_equalTo(0.5);
}];
[self.ConText mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(line.mas_bottom).offset(5);
make.right.equalTo(line);
make.left.equalTo(line);
}];
[self.pyphotosView mas_updateConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self.ConText.mas_bottom).offset(5);
make.left.equalTo(self.ConText);
make.right.equalTo(self.ConText);
make.height.mas_equalTo(0).priorityLow();
make.bottom.equalTo(self).offset(-5).priorityLow();
}];
自定义View上模型数据：
#pragma mark 数据接收
-(void)setModel:(Model*)model{
self.icon.image= [UIImageimageNamed:model.icon];
self.name.text= model.Name;
self.time.text= model.Time;
self.ConText.text= model.context;
self.pyphotosView.thumbnailUrls= model.arrys;
//判断图片数量
if (self.pyphotosView.thumbnailUrls.count == 0) {
[self.pyphotosView mas_updateConstraints:^(MASConstraintMaker *make) {
make.height.mas_equalTo(0).priorityMedium();
make.bottom.equalTo(self).offset(-5).priorityMedium();
}];
}
else if (self.pyphotosView.thumbnailUrls.count>0){
//图片的宽高
self.pyphotosView.photoHeight=kscreenH*0.15;
self.pyphotosView.photoWidth=SCREEN_W*0.26;
//间距
self.pyphotosView.photoMargin=SCREEN_W*0.035;
//临时图片控件高度
CGFloath =0.0;
if(self.pyphotosView.thumbnailUrls.count == 1){
// self.pyphotosView.photoHeight = [UIScreen mainScreen].bounds.size.height * 1;
self.pyphotosView.photoWidth=SCREEN_W*0.93;
self.pyphotosView.photoHeight=kscreenH*0.45;
self.pyphotosView.oneImageFullFrame=NO;
h =self.pyphotosView.photoHeight;
}else{
h =kscreenH*0.15;
}
//判断几行高度
CGFloat height = (((self.pyphotosView.thumbnailUrls.count-1) /3+1) * (h+ self.pyphotosView.photoMargin)+self.pyphotosView.photoMargin);
[self.pyphotosView mas_updateConstraints:^(MASConstraintMaker *make) {
make.height.mas_equalTo(height).priorityMedium();
// make.height.mas_equalTo(height);
}];
}
}
cell里面添加自定义的View：
[self.dynamicView mas_makeConstraints:^(MASConstraintMaker *make) { make.edges.equalTo(self.contentView);
}];
cell里面的模型：
#pragma mark -数据接口
-(void)configureCellWithData:(Model*)model{
self.dynamicView.model = model;
}
控制器上：
1.tableView上一定要注册registerClass
2.//自适应高度
-(CGFloat)tableView:(UITableView*)tableView heightForRowAtIndexPath:(NSIndexPath*)indexPath{
return [_tableView fd_heightForCellWithIdentifier:TaID cacheByIndexPath:indexPath configuration:^(id cell) {
[cellconfigureCellWithData:self.arrys[indexPath.row]];
}];
}
这就样可以自动适应cell了
提示一下：
由于FDTemplateLayoutCell一年多没更新，导致会出现以下bug（不知道是不是我约束问题还是什么，百度谷歌了很多，很多人都有这种问题）：
translatesAutoresizingMaskIntoConstraints property of the contentView of a UITableViewCell is not supported and will result in undefined behavior, as this property is managed by the owning UITableViewCell. Cell:>
emmm,恳请各位有解决办法请告诉我这个小菜鸟.
