If I click on 1 cell then value displayimage on last cell only it not display where i am click and which cell i am click how to handle toogle button change image for each and every cell click on button image this code.

-(void)changeMapType:(id)sender
{
    //changeimagetype =!changeimagetype;
//    sender.selected = changeimagetype;

    //sender.selected
    changeimagetype =!changeimagetype;
    if(changeimagetype == YES)
    {
        //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];
    }
    [self.tableView reloadData];

}

- (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];

    }

您能帮我更正代码吗?

推荐答案

尝试提供按钮标签作为表的行号.然后在按钮按下方法中检查标签，然后执行更改图像的逻辑.

Try giving the tag for the button as the row number of the table. Then check the tag in the button press method and then perform the logic to change image.

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

}
