RelatedCompanyCell.h里
@property (strong, nonatomic) IBOutlet UIImageView *companyPhoto;

RelatedCompanyController.m里
//创建全选按钮添加点击事件
UIButton *allCheckBtn = [[UIButton alloc]initWithFrame:CGRectMake(SCREEN_WIDTH - 50, 65, 20, 20)];
[allCheckBtn addTarget:self action:@selector(allCheckAction) forControlEvents:UIControlEventTouchUpInside];
[allCheckBtn setBackgroundImage:[UIImage imageNamed:@"unchecked"] forState:UIControlStateNormal];
[headerView addSubview:allCheckBtn];
self.allCheckBtn = allCheckBtn;
//给每一个cell上的按钮添加点击事件
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
RelatedCompanyCell *cell = [tableView dequeueReusableCellWithIdentifier:reuseItemIdentifier forIndexPath:indexPath];
//关闭UITableView cell的被选中效果
cell.selectionStyle = UITableViewCellSelectionStyleNone;
//设置边框
cell.layer.borderColor= [UIColor lightGrayColor].CGColor;
cell.layer.borderWidth= 0.3;
[cell.companyCheck addTarget:self action:@selector(cellBtnClicked:event:) forControlEvents:UIControlEventTouchUpInside];
cell.companyCheck.tag = indexPath.row;
return cell;
}
//单选
- (void)cellBtnClicked:(UIButton*)sender event:(id)event
{
NSSet *touches =[event allTouches];
UITouch *touch =[touches anyObject];
CGPoint currentTouchPosition = [touch locationInView:_tableView];
NSIndexPath *indexPath= [_tableView indexPathForRowAtPoint:currentTouchPosition];
if (indexPath!= nil)
{
sender.selected = !sender.selected;
if (sender.selected) {
[sender setImage:[UIImage imageNamed:@"checked"] forState:UIControlStateNormal];
}else{
[sender setImage:[UIImage imageNamed:@"unchecked"] forState:UIControlStateNormal];
}
}
}
//全选
- (void)allCheckAction{
for (RelatedCompanyCell *cell in self.tableView.visibleCells) {
cell.companyCheck.selected = !cell.companyCheck.selected;
if (cell.companyCheck.selected) {
[cell.companyCheck setImage:[UIImage imageNamed:@"checked"] forState:UIControlStateNormal];
[_allCheckBtn setBackgroundImage:[UIImage imageNamed:@"checked"] forState:UIControlStateNormal];
}else{
[cell.companyCheck setImage:[UIImage imageNamed:@"unchecked"] forState:UIControlStateNormal];
[_allCheckBtn setBackgroundImage:[UIImage imageNamed:@"unchecked"] forState:UIControlStateNormal];
}
}
}
其中通过cell上的button获取cell 如果用superview的话会很麻烦
可以通过这样的方法获取：
[cell.btn addTarget:self action:@selector(cellBtnClicked:event:) forControlEvents:UIControlEventTouchUpInside];- (void)cellBtnClicked:(UIButton*)sender event:(id)event{ NSSet *touches =[event allTouches]; UITouch *touch =[touches anyObject]; CGPoint currentTouchPosition = [touch locationInView:_tableView]; NSIndexPath *indexPath= [_tableView indexPathForRowAtPoint:currentTouchPosition]; if (indexPath!= nil) { // do something }}
