我有一个UITableview
我正在显示一些任务,并且每一行都有一个复选框来标记任务是否完成。
我希望在用户点击复选框时切换复选标记,并在用户点击该行时切换到详细视图。后者很简单,只需使用
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
但是,我想分隔选择区域,仅在选择时切换复选框accessoryview
被选中,并且仅当单元格的其余部分被选中时才进入详细视图。如果我添加一个UIbutton
在 - 的里面accessoryview
,用户将选择该行 ANDUIButton
当他们只想点击复选框时,对吧?
另外,如果用户只是通过拖动来滚动表格视图会怎样?accessoryview
?这不会触发对UIButton
在 TouchUp 上?
有人对如何做到这一点有任何想法吗?谢谢你的时间!
如何在该委托方法中管理附件点击:
- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
EDIT:
您可以对响应的自定义accessoryView执行类似的操作accessoryButtonTappedForRowWithIndexPath:
method.
In cellForRowAtIndexPath:
方法 -
BOOL checked = [[item objectForKey:@"checked"] boolValue];
UIImage *image = (checked) ? [UIImage imageNamed:@"checked.png"] : [UIImage imageNamed:@"unchecked.png"];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
CGRect frame = CGRectMake(0.0, 0.0, image.size.width, image.size.height);
button.frame = frame;
[button setBackgroundImage:image forState:UIControlStateNormal];
[button addTarget:self action:@selector(checkButtonTapped:event:) forControlEvents:UIControlEventTouchUpInside];
button.backgroundColor = [UIColor clearColor];
cell.accessoryView = button;
- (void)checkButtonTapped:(id)sender event:(id)event
{
NSSet *touches = [event allTouches];
UITouch *touch = [touches anyObject];
CGPoint currentTouchPosition = [touch locationInView:self.tableView];
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint: currentTouchPosition];
if (indexPath != nil)
{
[self tableView: self.tableView accessoryButtonTappedForRowWithIndexPath: indexPath];
}
}
- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
{
NSMutableDictionary *item = [dataArray objectAtIndex:indexPath.row];
BOOL checked = [[item objectForKey:@"checked"] boolValue];
[item setObject:[NSNumber numberWithBool:!checked] forKey:@"checked"];
UITableViewCell *cell = [item objectForKey:@"cell"];
UIButton *button = (UIButton *)cell.accessoryView;
UIImage *newImage = (checked) ? [UIImage imageNamed:@"unchecked.png"] : [UIImage imageNamed:@"checked.png"];
[button setBackgroundImage:newImage forState:UIControlStateNormal];
}
