我有一个表格视图,其中包含用户选择的选项列表(这是一个编辑页面)。
表格视图如下所示
苹果
UITableViewCellAccessoryCheckmark
橙子
UITableViewCellAccessoryNone
菠萝
UITableViewCellAccessoryCheckmark
香蕉
UITableViewCellAccessoryNone
- (void)viewDidLoad {
self.mySavedFruitsArray = [myDBOperations getMyFruitsList:[appDelegate getDBPath]:self.myId];
}
/ Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:
(NSIndexPath *)indexPath
//-------------------------------------------------------------------------------
{
static NSString *CellIdentifier = @"PoemTypeCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"MyIdentifier"]autorelease];
}
NSDictionary *aDict = [self.myFruitsArr objectAtIndex:indexPath.row];
NSString *aValue = [aDict objectForKey:@"value"];
NSString *aId = [aDict objectForKey:@"key"];
cell.textLabel.text = aValue;
cell.accessoryType = UITableViewCellAccessoryNone;
NSDictionary *aSavedDict = [self.mySavedFruitsArray objectAtIndex:indexPath.row];
NSString *Value = [aSavedDict objectForKey:@"value"];
NSString *Id = [aSavedDict objectForKey:@"key"];
if ( aId == Id ){
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}else
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
return cell;
}
mySavedFruitsArray
- 它保存用户选择的水果。
myFruitsArr
- 这有常见的水果清单
现在我想知道如何显示UITableViewCellAccessoryCheckmark
与mySavedFruitsArray
.
我的意思是,在这个编辑视图中,我想显示带有用户选择选项的水果列表。
请让我知道该怎么做。
我试过这样,但没有用。
/ Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:
(NSIndexPath *)indexPath
//-------------------------------------------------------------------------------
{
static NSString *CellIdentifier = @"PoemTypeCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"MyIdentifier"]autorelease];
}
NSDictionary *aDict = [self.myFruitsArr objectAtIndex:indexPath.row];
NSString *aValue = [aDict objectForKey:@"value"];
NSString *aId = [aDict objectForKey:@"key"];
cell.textLabel.text = aValue;
cell.accessoryType = UITableViewCellAccessoryNone;
NSDictionary *aSavedDict = [self.mySavedFruitsArray objectAtIndex:indexPath.row];
NSString *Value = [aSavedDict objectForKey:@"value"];
NSString *Id = [aSavedDict objectForKey:@"key"];
if ( aId == Id ){
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}else
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
return cell;
}
请注意 self.mySavedFruitsArray 可能不总是等于 myFruitsArr (因为用户只能选择一种水果)。
