Try this. In your cellForRowAtIndexPathdelegate method put the following code.
尝试这个。在您的cellForRowAtIndexPath委托方法中放置以下代码。
if (cell == nil) {
...
[[cell imageView] setImage:[UIImage imageNamed:@"checkMark"]];
...
}
[[cell imageView] setHidden:YES];
if (indexPath.row == selectedRow) {
[[cell imageView] setHidden:NO];
}
Have a integer variable named selectedRowand in your didSelectRowAtIndexPathdelegate method include the following code,
有一个名为selectedRow的整数变量，并在您的didSelectRowAtIndexPath委托方法中包含以下代码，
...
selectedRow = indexPath.row;
[self.tableView reloadData];
Make sure you initialize ,
确保你初始化，
selectedRow = -1;
in initmethod or somewhere where it will be initialized before the table view loads.
在init方法中或在表视图加载之前将被初始化的某个地方。
