UI今天给了个需求，把乱序的单词拼成一句话，如下图：
哈哈，这个的确就是当时的想法，不要怂就是干~
那就来试试吧，话不多说，直接上代码：
-(UITableView*)tagsView{
if (!_tagsView){
_tagsView =[[UITableView alloc]initWithFrame:CGRectMake(0, 239, kScreenWidth, kScreenHeight/2-60) style:UITableViewStylePlain];
_tagsView.alwaysBounceVertical = YES;
_tagsView.delegate=self;
_tagsView.dataSource=self;
}
return _tagsView;
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView*)tableView {
return self.groups.count;
}
- (NSInteger)tableView:(UITableView*)tableView numberOfRowsInSection:(NSInteger)section {
EFTagGroupItem*group =self.groups[section];
returngroup.data.count;
}
- (UITableViewCell*)tableView:(UITableView*)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath {
if(indexPath.section==0) {
EFHobbyCell *cell = [tableView dequeueReusableCellWithIdentifier:hobbyCell];
cell.tagList=self.tagList;
returncell;
}
EFGroupItem*group =self.groups[indexPath.section];
EFTagGroupItem*tagGroup = group.data[indexPath.row];
EFTagGroupCell *cell = [tableView dequeueReusableCellWithIdentifier:tagGroupCell forIndexPath:indexPath];
cell.collectionView.delegate = self;
cell.tagGroup= tagGroup;
returncell;
}
- (CGFloat)tableView:(UITableView*)tableView heightForRowAtIndexPath:(NSIndexPath*)indexPath
{
if(indexPath.section==0) {
return _tagList.tagListH;
}
EFGroupItem*group =self.groups[indexPath.section];
EFTagGroupItem*tagGroup = group.data[indexPath.row];
returntagGroup.cellH;
}
- (CGFloat)tableView:(UITableView*)tableView heightForHeaderInSection:(NSInteger)section
{
return 0;
}
#pragma mark - UICollectionViewDelegate
- (void)collectionView:(UICollectionView*)collectionView didSelectItemAtIndexPath:(NSIndexPath*)indexPath
{
EFTagCell*cell = (EFTagCell*)[collectionViewcellForItemAtIndexPath:indexPath];
EFTagsItem*item = cell.item;
item.isSelected = !item.isSelected;
cell.item= item;
NSString*tagStr = cell.tagLabel.text;
if(item.isSelected) {
[self.tagListaddTag:tagStr];
[self.selectTagDictsetObject:cellforKey:tagStr];
[self.selectTagArraddObject:tagStr];
}else{
[self.tagListdeleteTag:tagStr];
for(inti =0;i<_selectTagArr.count;i++){
if([_selectTagArr[i]isEqualToString:tagStr]){
[_selectTagArrremoveObjectAtIndex:i];
i--;
}
}
}
[self.tagsView reloadSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationNone];
}
很简单的需求，有不懂的可以线下交流 wx:dwl-1591293009
