Question

在customCell中我创建了一些UIButtons和[self addSubview：button]; 在UITableView [button addTarget：action：forControlEvents：]中，当我单击单元格indexPath.row = 0中的按钮时，单击了indexPath.row = 11; 如何点击按钮和其他按钮不受影响？

enter code here

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:
         (NSIndexPath *)indexPath
{   
    static NSString *identifier = @"cell";
    SettingTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
    if (cell == nil) {
        cell = [[[SettingTableViewCell alloc]initWithStyle:UITableViewCellStyleDefault
                  reuseIdentifier:identifier]autorelease];
    }

    if (indexPath.section == 0) {
        [cell.customBtn setTitle:@"" forState:UIControlStateNormal];
    }
    else if(indexPath.section == 1){

        if (indexPath.row == 0) {
        [cell.customBtn setTitle:@"" forState:UIControlStateNormal];
    }
    else if(indexPath.row == 1){
        [cell.customBtn setTitle:@"" forState:UIControlStateNormal];
    }
    else{
        [cell.customBtn setTitle:@"" forState:UIControlStateNormal];
    }
    else if (indexPath.section == 2){
        if (indexPath.row == 0) {
            [cell.customBtn setTitle:@"" forState:UIControlStateNormal];
        }
        else {
            [cell.customBtn setTitle:@"" forState:UIControlStateNormal];
        }
    }
    [cell.WIFIButton addTarget:self action:@selector(openOrCloseButtonClick:) 
       forControlEvents:UIControlEventTouchUpInside];
    return cell;
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 7;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    if (section == 1) {
        return 3;
    }
    else if(section == 2){
        return 2;
    }
    else if(section == 6){
        return 4;
    } 
    else{
        return 1;
    }
}


enter code here
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
        // Initialization code
        CGFloat originX = IsIOS7?10:15;
        UILabel *nameLabel = [[UILabel alloc]initWithFrame:CGRectMake(originX, 7, 150, 30)];
        nameLabel.backgroundColor = [UIColor clearColor];
        nameLabel.font = [UIFont systemFontOfSize:16];
        nameLabel.textColor = [UIColor blackColor];
        self.nameLabel = nameLabel;
        [self addSubview:nameLabel];
        [nameLabel release];
        CGFloat rightX = IsIOS7?180:160;
        UILabel *fileSizeLabel = [[UILabel alloc]initWithFrame:CGRectMake(rightX - 10, 10, 100,  
                                                                            25)];
        fileSizeLabel.backgroundColor = [UIColor clearColor];
        fileSizeLabel.font = [UIFont systemFontOfSize:14];
        fileSizeLabel.hidden = YES;
        self.fileSizeLabel = fileSizeLabel;
        [self addSubview:fileSizeLabel];
        [fileSizeLabel release];
        //This is customButton
        UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
        button.frame = CGRectMake(rightX, 10, 50, 25);
        button.backgroundColor = [UIColor grayColor];
        self.WIFIButton = button;
        [self addSubview:button];
}

Answer 1

在代码上稍微跳一下枪，但请考虑以下内容。添加一种方法，可以在不使用标签的情况下查找显示视图的单元格。

- (NSIndexPath *)indexPathOfSubview:(UIView *)view {
    while (view && ![view isKindOfClass:[UITableViewCell self]]) {
        view = view.superview;
    }
    UITableViewCell *cell = (UITableViewCell *)view;
    return [self.tableView indexPathForCell:cell];
}

这假设您有一个名为tableView的插座指向一个表（它假定该参数是一个表的单元格的子视图）。现在，按下按钮时运行的任何方法：

- (IBAction)myButtonPressed:(id)sender {
    NSIndexPath *indexPath = [self indexPathOfSubview:sender];
    NSLog(@"button pressed in section %d, at row %d", indexPath.section, indexPath.row);
    // ta-da!
}

Answer 2

将静态更改为动态单元格

static NSString *identifier = @"cell";

到

NSString *identifier = [NSString stringWithFormat:@"cell%d",indexPath.row];

可能是它的工作

我想将自定义UIButton添加到UITableViewCell
