    {
        //flagButton=1;
        //[check setImage:[UIImage imageNamed:@"alarm_OF.png"] forState:UIControlStateNormal];
    onButtonView.image = [UIImage imageNamed:@"alarm_OF.png"];
    [mimageButton setImage:onButtonView.image forState:UIControlStateNormal];
    }
    else
    {
        //flagButton=2;
    onButtonView.image = [UIImage imageNamed:@"alarm_ON.png"];
    [mimageButton setImage:onButtonView.image forState:UIControlStateNormal];

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    // Return the number of sections.
    return 2;
}

// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
        mimageButton = [UIButton buttonWithType:UIButtonTypeCustom];
        mimageButton.frame=CGRectMake(10, 10, 20, 20);
        mimageButton.tag = 1;
        //mimageButton = [UIButton buttonWithType:UIButtonTypeCustom];
        //[mimageButton setImage:[UIImage imageNamed:@"alarm_ON.png”] //forState:UIControlStateNormal];
        //[mimageButton setImage:[UIImage imageNamed:@"alarm_OF.png”] //forState:UIControlStateSelected];
        onButtonView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 20, 20)];
        onButtonView.tag = 2;
        onButtonView.image = [UIImage imageNamed:@"alarm_ON.png”];
        [mimageButton setBackgroundImage:[onButtonView.image stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0] forState:UIControlStateNormal];
        [cell.contentView addSubview:mimageButton];
        [mimageButton addTarget:self action:@selector(changeMapType:) forControlEvents: UIControlEventTouchUpInside];
    }

你能帮我修改代码吗?

Answer 1

尝试将按钮的标记作为表的行号。然后检查按钮按下方法中的标签，然后执行更改图像的逻辑。

-(void)changeMapType:(id)sender
{
   UIButton *button = (UIButton *)sender;
   // Check tag of button
   // Some code
   //Change image after checking
   [button setImage:yourImage forState:UIControlStateNormal];
}

取一个数组，将选中的按钮标签存储在数组中，同时在cellForRowAtIndex方法中显示按钮。检查按钮标签是否在那个数组中。
