dimissModalViewControllerAnimated causing tableView to be full screen? - iphone

Question

I have a RootViewController with 2 tableViews as subviews (created in IB) each with their own tableViewController class (handleing fetchRequests etc.)
1 tableView is static (no data changed by user or modelViews).
tableView 2 has a button in the header which presents an imagePickerController.
No issues so far.
Problem is, when i dismiss the imagePicker
[self dismissModalViewControllerAnimated:YES];
TableView 2 becomes full screen i have tried
[[self rootViewController] dismissModalViewControllerAnimated:YES]
Nothing happens at all. It sticks on the image picker.
I suspect this is due to there being very little of the view being created programmaticaly.
Any ideas?
Thanks in advance.

-(IBAction)addImageTableAPressed {
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
[self presentModalViewController:imagePicker animated:YES];
[imagePicker release];

As I mentioned in one of my comments, I would prefer having a single view controller managing the two table views. Define a UIView (the rootView) including 2 subviews (tableViewA and tableViewB). Your RootViewController's view will be rootView, and this controller will have to be the data source and delegate of both table views. The code I will give here is by no means complete nor optimal, but gives you a good idea of what is needed to implement my solution.
For example:
#interface RootViewController <UITableViewDelegate, UITableViewDataSource> {
NSArray *dataArrayA;
NSArray *dataArrayB;
UITableView tableViewA;
UITableView tableViewB;
NSManagedObjectContext *context;
}
#property (nonatomic, retain) NSArray *dataArrayA;
#property (nonatomic, retain) NSArray *dataArrayB;
// in IB, link the dataSource and delegate outlets of both tables to RootViewController
#property (nonatomic, retain) IBOutlet UITableView tableViewA;
#property (nonatomic, retain) IBOutlet UITableView tableViewB;
// this property will allow you to pass the MOC to the RootViewController from
// the parent view controller, instead of accessing the app delegate from RootViewController
#property (nonatomic, retain) NSManagedObjectContext *context;
// ... etc.
#end
#implementation RootViewController
#synthesize dataArrayA;
#synthesize dataArrayB;
#synthesize tableViewA;
#synthesize tableViewB;
#synthesize context;
// initialize dataArrayA and dataArrayB
- (void)viewDidLoad {
[super viewDidLoad];
NSError *error = nil;
// initialize and configure your fetch request for data going into tableViewA
NSFetchRequest fetchRequestA = [[NSFetchRequest alloc] init];
// configure the entity, sort descriptors, predicate, etc.
// ...
// perform the fetch
self.dataArrayA = [context executeFetchRequest:fetchRequestA error:&error];
// do the same for the data going into tableViewB - the code is very similar, you
// could factor it out in a private method instead of duplicating it here
// NSFetchRequest fetchRequestB = [[NSFetchRequest alloc] init];
// omitting the details ... etc.
self.dataArrayB = [context executeFetchRequest:fetchRequestB error:&error];
// release objects you don't need anymore, according to memory management rules
[fetchRequestA release];
[fetchRequestB release];
}
// Table view methods
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// if you have a different number of sections in tableViewA and tableViewB
/*
if (tableView == tableViewA) {
return ??;
} else {
return ??
}
*/
// otherwise, if both table views contain one section
return 1;
}
// Customize the number of rows in each table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if (tableView == tableViewA) {
return [dataArrayA count];
} else {
return [dataArrayB count];
}
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = nil;
if (tableView == tableViewA) {
// get the data for the current row in tableViewA
id objectA = [dataArrayA objectAtIndex:indexPath.row];
// configure the cell for tableViewA
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifierA];
// etc...
} else {
// get the data for the current row in tableViewB
id objectB = [dataArrayB objectAtIndex:indexPath.row];
// configure the cell for tableViewB
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifierB];
// etc...
}
return cell;
}
// And so on, the same idea applies for the other UITableViewDelegate you would need to
// implement...
- (void)dealloc {
[dataArrayA release];
[dataArrayB release];
[tableViewA release];
[tableViewB release];
[context release];
// etc...
[super dealloc];
}
#end
I hope you'll find this useful.
