我在每个单元格中有一个表格视图，两个按钮作为编辑和取消。当我在相同的单元格编号中同时点击编辑按钮时，取消按钮图像应该变化。例如。当用户选择seond cells edit按钮时，只有第二个单元格中的取消按钮才能更改其图像。
我的问题是当我点击任何单元格编辑按钮时，另一个单元格取消按钮图像会自动更改。
我希望当用户点击第一个单元格时，第一个单元格取消按钮应该更改而不是其他单元格？请举例说明我们如何做到这一点？我知道这种重复使用细胞的原因是什么？
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
simpleTableIdentifier = @"MenuNameCell";
MenuNameCell *cell = (MenuNameCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell== nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"MenuNameCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
NSLog(@"---------new cell agin");
}
else
{
NSArray *arrayView = [cell.contentView subviews];
for (UIView *vTemp in arrayView)
{
[vTemp removeFromSuperview];
}
NSLog(@"---No New Cell hiiii");

您正在使用自定义单元格，然后将此代码放入您的自定义类并获取特定单元格的特定发件人
-(IBAction)yourButtonMehod:(id)sender
{
UIView *senderButton = (UIView*) sender;
NSIndexPath *indexPath = [(UITableView *)self.superView indexPathForCell: (UITableViewCell*)[[senderButton superView]superView]];
}
现在，您可以获取发件人并使用indexpath.row您可以执行任何操作

在按钮操作方法
中-(IBAction)cellButtonPressed:(id)sender withEvent:(UIEvent *)event
{
UITouch * touch = [[event allTouches] anyObject];
CGPoint location = [touch locationInView: bulletinTable];
NSIndexPath * indexPath = [bulletinTable indexPathForRowAtPoint: location];
}
你的cellForRowAtIndexPath方法
[cell.accessory addTarget:self action:@selector(cellButtonPressed:withEvent:) forControlEvents:UIControlEventTouchUpInside];
这应该有用。
