I have problems entering a next view in the TableViewController. When I click on the cells i see the NSLog-text, but there is no action and no second view. This means the program enter the methods but does nothing. What is my fault? I am testing around without getting any solution.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.row==0) {
NSLog(@"Index 0");
AudioViewController *audioviewcontroller = [[AudioViewController alloc] initWithNibName:@"AudioViewController" bundle:nil];
[self.navController pushViewController:audioviewcontroller animated:YES];
[audioviewcontroller release];
[tableView deselectRowAtIndexPath: indexPath animated:YES];
}
if (indexPath.row==1) {
NSLog(@"Index 1");
DisplayViewController *displayviewcontroller = [[DisplayViewController alloc] initWithNibName:@"DisplayViewController" bundle:nil];
[self.navController pushViewController:displayviewcontroller animated:YES];
[displayviewcontroller release];
[tableView deselectRowAtIndexPath: indexPath animated:YES];
}
if (indexPath.row==2) {
LichtViewController *lichtviewcontroller = [[LichtViewController alloc] initWithNibName:@"LichtViewController" bundle:nil];
[self.navController pushViewController:lichtViewController animated:YES];
[lichtviewcontroller release];
[tableView deselectRowAtIndexPath: indexPath animated:YES];
NSLog(@"Index 2");
}
if (indexPath.row==3) {
NSLog(@"Index 3");
ProjektorViewController *projektorviewcontroller = [[ProjektorViewController alloc] initWithNibName:@"ProjektorViewController" bundle:nil];
[self.navController pushViewController:projektorviewcontroller animated:YES];
[tableView deselectRowAtIndexPath: indexPath animated:YES];
[projektorviewcontroller release];
}
}
Moreover I tried this code:
UIView *currentView = self.view;
UIView *theWindow = [currentView superview];
[currentView removeFromSuperview];
UIView* audioView= audioviewcontroller.view;
[theWindow addSubview:audioView];
[self.navController pushViewController:audioviewcontroller animated:YES]; [audioviewcontroller release];
[tableView deselectRowAtIndexPath: indexPath animated:YES];
I get no warning but a crash and the debugger console shows:

Thank you for help in advance
Try the codes below if it works for you, this is how I declare my objects/variables in the tableView didSelectRowAtIndexPath. Declare your object (views) at the top of the function
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
AudioViewController *audioviewcontroller = [[AudioViewController alloc] initWithNibName:@"AudioViewController" bundle:nil];
DisplayViewController *displayviewcontroller = [[DisplayViewController alloc] initWithNibName:@"DisplayViewController" bundle:nil];
LichtViewController *lichtviewcontroller = [[LichtViewController alloc] initWithNibName:@"LichtViewController" bundle:nil];
ProjektorViewController *projektorviewcontroller = [[ProjektorViewController alloc] initWithNibName:@"ProjektorViewController" bundle:nil];
if (indexPath.row==0) {
NSLog(@"Index 0");
[self.navController pushViewController:audioviewcontroller animated:YES];
[audioviewcontroller release];
[tableView deselectRowAtIndexPath: indexPath animated:YES];
}
if (indexPath.row==1) {
NSLog(@"Index 1");
[self.navController pushViewController:displayviewcontroller animated:YES];
[displayviewcontroller release];
[tableView deselectRowAtIndexPath: indexPath animated:YES];
}
if (indexPath.row==2) {
[self.navController pushViewController:lichtViewController animated:YES];
[lichtviewcontroller release];
[tableView deselectRowAtIndexPath: indexPath animated:YES];
NSLog(@"Index 2");
}
if (indexPath.row==3) {
NSLog(@"Index 3");
[self.navController pushViewController:projektorviewcontroller animated:YES];
[tableView deselectRowAtIndexPath: indexPath animated:YES];
[projektorviewcontroller release];
}
}
