[iPhone] Multiple viewControllers cause problems

Question

Hey,
I have a problem, by using multiple view Controllers. I create multiple view programmically by calling this method multiple times at the beginning of my application:
- (IUCViewController*) _createView:(CGRect)frame outOf:(NSMutableDictionary*)dict withID:(NSString*)viewID {
UITableView* actualView = [[UITableView alloc] initWithFrame:frame style:UITableViewStyleGrouped];
actualView.tag = viewID.intValue;
UIView* actualElement;
NSString* elementTag;
NSObject* actualObject;
IUCViewController* controller = [[IUCViewController alloc] initWithNibName:nil bundle:nil];
controller.editing = NO;
controller.navigationItem.rightBarButtonItem = [[SendingButton alloc]initWithReceiver:controller];
textController = controller.textController;
for(id key in dict) {
actualObject = [dict objectForKey:key];
switch([_allowedElements indexOfObject:key])
case 4: //elements
_actualDictionary = [dict objectForKey:key];
for(id elementKey in _actualDictionary) {
if([elementKey isEqualToString:@"parent"]) {
else {
actualElement = [self _createElement:frame outOf:elementKey];
elementTag = elementKey;
[actualElement setTag:elementTag.intValue];
[actualView addSubview:actualElement];
if([_viewType isEqualToString:@"table"]) {
controller.actualView = (IUCTableView*)actualElement;
return controller;
break;
default://various property
break;
controller.actualView = actualView;
return controller;
After all, I push the mainView to my navigationController. So far so good, the view appears:
- (void) receivedNewLayout {
NSMutableDictionary* views = [_xmlController views];
IUCTextController* controller = [views objectForKey:_xmlController.mainViewID];
[navigationController pushViewController:controller animated:YES];
[navigationController setNavigationBarHidden:FALSE animated:FALSE];
This causes two problems:
1.) When I simulate a memory warning, it is send to every viewController, not just to the one on top. Is there any chance to fix this?
2.) This is strange, because I did not have this problem, when I just had one viewController. The textfields on the view do not react anymore. There is no keyboard showing or any event triggered. I do not why.
Can u help me with these problems?
