Implement the delegate method (void)textViewDidChange:(UITextView *)textView
. You could use the tag property of the textView to distinguish which one was changed.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"MySpecialCell";
MySpecialCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell) {
cell = [[MySpecialCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
cell.mySpecialTextView.delegate = self;
}
cell.mySpecialTextView.tag = indexPath.row;
return cell;
}
- (void)textViewDidChange:(UITextView *)textView
int rowOfTextViewThatJustChanged = textView.tag;
}
Update!
Here's an approach that uses associated objects instead of tags.
static NSString *const kIndexPathKey = @"indexPathKey";
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"MultiSelectCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
UISwitch *switchView = [[UISwitch alloc] init];
[switchView addTarget:self action:@selector(switchValueChanged:) forControlEvents:UIControlEventValueChanged];
cell.accessoryView = switchView;
}
UISwitch *switchView = (id)cell.accessoryView;
[self setIndexPath:indexPath onSwitch:switchView];
switchView.on = [self isIndexPathSelected:indexPath];
id item = [self itemAtIndexPath:indexPath];
cell.textLabel.text = safePerformSelector(item, self.itemDescriptionSelector);
return cell;
}
- (void)switchValueChanged:(UISwitch *)sender {
NSIndexPath *indexPath = [self indexPathOfSwitch:sender];
[self setRowSelected:sender.isOn atIndexPath:indexPath];
[self.delegate didSelectItem:[self itemAtIndexPath:indexPath] atIndexPath:indexPath selected:sender.isOn sender:self];
}
- (void)setIndexPath:(NSIndexPath *)indexPath onSwitch:(UISwitch *)switchView {
[switchView setAssociatedObject:indexPath forKey:kIndexPathKey];
}
- (NSIndexPath *)indexPathOfSwitch:(UISwitch *)switchView {
return [switchView associatedObjectForKey:kIndexPathKey];
}
@implementation NSObject (AssociatedObjects)
- (void)setAssociatedObject:(id)object forKey:(NSString *const)key {
objc_setAssociatedObject(self, (__bridge const void *)(key), object, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
}
- (id)associatedObjectForKey:(NSString *const)key {
return objc_getAssociatedObject(self, (__bridge const void *)(key));
}
