iPhoneで下の画像のようなメニューを表示したい
このようにナビゲートすることは可能ですか?
マルチレベルの Uitable ビュー用に次のコードを実装します
- (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.text=[[self.arForTable objectAtIndex:indexPath.row] valueForKey:@"name"];
[cell setIndentationLevel:[[[self.arForTable objectAtIndex:indexPath.row] valueForKey:@"level"] intValue]];
return cell;
}
didSelectRowAtIndexPath メソッド
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
NSDictionary *d=[self.arForTable objectAtIndex:indexPath.row];
if([d valueForKey:@"Objects"]) {
NSArray *ar=[d valueForKey:@"Objects"];
BOOL isAlreadyInserted=NO;
for(NSDictionary *dInner in ar ){
NSInteger index=[self.arForTable indexOfObjectIdenticalTo:dInner];
isAlreadyInserted=(index>0 && index!=NSIntegerMax);
if(isAlreadyInserted) break;
}
if(isAlreadyInserted) {
[self miniMizeThisRows:ar];
} else {
NSUInteger count=indexPath.row+1;
NSMutableArray *arCells=[NSMutableArray array];
for(NSDictionary *dInner in ar ) {
[arCells addObject:[NSIndexPath indexPathForRow:count inSection:0]];
[self.arForTable insertObject:dInner atIndex:count++];
}
[tableView insertRowsAtIndexPaths:arCells withRowAnimation:UITableViewRowAnimationLeft];
}
}
}
アイテムを展開するための miniMizeThisRows メソッド
-(void)miniMizeThisRows:(NSArray*)ar{
for(NSDictionary *dInner in ar ) {
NSUInteger indexToRemove=[self.arForTable indexOfObjectIdenticalTo:dInner];
NSArray *arInner=[dInner valueForKey:@"Objects"];
if(arInner && [arInner count]>0){
[self miniMizeThisRows:arInner];
}
if([self.arForTable indexOfObjectIdenticalTo:dInner]!=NSNotFound) {
[self.arForTable removeObjectIdenticalTo:dInner];
[self.tableView deleteRowsAtIndexPaths:
[NSArray arrayWithObject:[NSIndexPath indexPathForRow:indexToRemove inSection:0]]
withRowAnimation:UITableViewRowAnimationRight];
}
}
}
