我在tableview中显示一个名字的数组。
选中的行将带有支票表示,并且很好地我将选定的名称添加到列表中。
我的代码是
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [self.sourceArray count];;
}
// 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];
}
[cell.textLabel setText:[self.sourceArray objectAtIndex:indexPath.row]];
if ([self.selectedArray containsObject:[agentemails objectAtIndex:indexPath.row]]){
[cell setAccessoryType:UITableViewCellAccessoryCheckmark];
}
else
{
[cell setAccessoryType:UITableViewCellAccessoryNone];
}
return cell;
}
#pragma mark -
#pragma mark Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if ([self.selectedArray containsObject:[agentemails objectAtIndex:indexPath.row]]){
[self.selectedArray removeObjectAtIndex:[self.selectedArray indexOfObject:[agentemails objectAtIndex:indexPath.row]]];
}
else
{
[self.selectedArray addObject:[agentemails objectAtIndex:indexPath.row]];
}
[tableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationNone];
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
现在我需要放置一个按钮select-all,当我使用点击它时,我需要检查表中的所有名称我怎么能做任何一个请帮助我。
提前感谢你。

尝试在标题中添加BOOL,然后执行以下操作:
-(IBAction)buttonPressed:(id)sender{
myBoolean = YES;
[tableView reloadData];
myBoolean = NO;
}
然后,在cellForRowAtIndexPath方法中,只需添加:
if(myBoolean){
[cell setAccessoryType:UITableViewCellAccessoryCheckmark];
}

- (IBAction)selectAll:(id)sender
{
if(myBoolean)
{
for (NSInteger s = 0; s < self.iTable.numberOfSections; s++)
{
for (NSInteger r = 0; r < [self.iTable numberOfRowsInSection:s]; r++)
{
[[self.iTable cellForRowAtIndexPath:[NSIndexPath indexPathForRow:r inSection:s]] setAccessoryType:UITableViewCellAccessoryNone];
}
}
myBoolean = NO;
}
else
{
for (NSInteger s = 0; s < self.iTable.numberOfSections; s++)
{
for (NSInteger r = 0; r < [self.iTable numberOfRowsInSection:s]; r++)
{
[[self.iTable cellForRowAtIndexPath:[NSIndexPath indexPathForRow:r inSection:s]] setAccessoryType:UITableViewCellAccessoryCheckmark];
}
}
myBoolean = YES;
}
}
