UITbaleView上按鈕的單選，uitbaleview單選

UITbaleView上按鈕的單選，uitbaleview單選

設定Id屬性，標記是哪個cell

@property (nonatomic,assign)NSInteger Id;

設定一個普通狀態和選中狀態圖片不同的按鈕

  _choose = [[UIButton alloc]init];        [_choose setImage:[UIImage imageNamed:@"about_未勾選"] forState:UIControlStateNormal];        [_choose setImage:[UIImage imageNamed:@"about_勾選"] forState:UIControlStateSelected];        [_choose addTarget:self action:@selector(choosePressed:) forControlEvents:UIControlEventTouchUpInside];        [self.contentView addSubview:_choose];

- (void)layoutSubviews {    _choose.frame = CGRectMake(10, 120+wei_tiao, 20, 20);}

設定一個可調整選中或者為選中的方法

- (void)setChecked:(BOOL)checked {    if (checked) {        _choose.selected = YES;    }else {        _choose.selected = NO;    }}

cell上按鈕的單擊事件

/** *  選擇勾選 * *  @param sender 按鈕 */- (void)choosePressed:(UIButton *)sender {    sender.selected = YES;    if (_chooseBlock) {        _chooseBlock(self.Id);    }}

設定一個全域變數來判定點了哪一個cell

    NSInteger _cellIndex;

 

tableView代理：- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {    ShippingAddressCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cellID"];    cell.selectionStyle = UITableViewCellSelectionStyleNone;    cell.Id = indexPath.row;    if (_cellIndex == indexPath.row) {        [cell setChecked:YES];    }else {        [cell setChecked:NO];    }    [cell setChooseBlock:^(NSInteger index) {        _cellIndex = index;        [_tableView reloadData];    }];    return cell;}

補：使用了block作為屬性回調

1.申明block屬性

@property (copy, nonatomic) void(^chooseBlock)(NSInteger index);

2.在本類裡面調用

 if (_chooseBlock) {        _chooseBlock(self.Id);    }

3.使用block屬性：

  [cell setChooseBlock:^(NSInteger index) {        _cellIndex = index;        [_tableView reloadData];    }];
