I want to do pass selected row text from first tab's table view to second tab's view label. I try this but it not work :S stringdir is a nsstring
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
SecondViewController *detailViewController = [[SecondViewController alloc]initWithNibName:#"SecondView" bundle:nil];
// ...
// Pass the selected object to the new view controller.
[self.navigationController pushViewController:detailViewController animated:YES];
detailViewController.stringdir= [ws2.CustomerName objectAtIndex:[indexPath row]];
NSLog(#"şişşşt %# ", detailViewController.stringdir);
[detailViewController release];
}
Move detailViewController.stringdir = ... before you push the view controller to nav controller stack.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
SecondViewController *detailViewController = [[SecondViewController alloc]initWithNibName:#"SecondView" bundle:nil];
detailViewController.stringdir= [ws2.CustomerName objectAtIndex:[indexPath row]];
NSLog(#"şişşşt %# ", detailViewController.stringdir);
// Pass the selected object to the new view controller.
[self.navigationController pushViewController:detailViewController animated:YES];
[detailViewController release];
}

Can I not use Navigation control to switch my UIViewController?
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:NO];
BATTrailsViewController *trailsController = [[BATTrailsViewController alloc] initWithStyle:UITableViewStylePlain];
trailsController.selectedRegion = [regions objectAtIndex:indexPath.row];
[[self navigationController] pushViewController:trailsController animated:YES];
}
Can I do this without using [[self navigationController] pushViewController:trailsController animated:YES];??
I want my UITableView selectrow to a new UIViewController without navigation.
try using
[self presentViewController:animated:completion];
Hope this helps.
In my project I have tableView with 10 cells. And in didSelectRowAtIndexPath all cells have multiple ViewController (files) so, my didSelectRowAtIndexPath looks like
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if(indexPath.row == 0) {
CallViewController *viewc = [[CallViewController alloc] initWithNibName:#"CallViewController" bundle:nil];
[self.navigationController pushViewController:viewc animated:YES];
}else if(indexPath.row == 1) {
BirthdayViewController *viewc = [[BirthdayViewController alloc] initWithNibName:#"BirthdayViewController" bundle:nil];
[self.navigationController pushViewController:viewc animated:YES];
}
so I don't want these conditions
I want my code be clean
I would suggest you to have an array that contains the Class object of your class and then create object and push like
//view did load
mutableArr = [[NSMutableArray alloc] init];
[mutableArr addObject:[CallViewController class]];
[mutableArr addObject:[BirthdayViewController class]];
....
....
Then in your
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row < [mutableArr count]) {
Class *obj = [mutableArr objectAtIndex:indexPath.row];
UIViewController *controller = [[objc alloc] initWithNibName:NSStringFromClass(obj) bundle:nil];
[self.navigationController pushViewController:controller animated:YES];
}
}
OR if this is looking more weird then you can do like this
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UIViewController *controller = nil;
switch(indexPath.row) {
case 0:
controller = [[CallViewController alloc] initWithNibName:#"CallViewController" bundle:nil];
break;
case 1;
controller = [[BirthdayViewController alloc] initWithNibName:#"BirthdayViewController " bundle:nil];
break;
}
[self.navigationController pushViewController:controller animated:YES];
}
What is your underlying data model for tableview? If you could add additional attribute as ViewController Class Name you could do something like
- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSDictionary *row = [rowData objectAtIndex:indexPath.row];
Class viewControllerClass =
NSClassFromString([row objectForKey:#"viewControllerClassName"]);
//Default VC init looks for nib file named as VC afaik, if not, you could
//add another attribute with init selector name
UIViewController *viewController =
[[viewControllerClass alloc] init];
[self.navigationController pushViewController:viewController animated:YES];
}
You can create array of strings corresponding to file names and use NSClassFromString function to allocate view controllers
NSArray *viewControllers = [NSArray arrayWithObjects:#"VC1", #"VC2", #"VC3", nil];
id viewController = [[NSClassFromString([viewControllers objectAtIndex:indexPath.row]) alloc] initWithNibName:[viewControllers objectAtIndex:indexPath.row] bundle:nil];
[[self navigationController] pushViewController:viewController animated:YES];
[viewController release];
You can do this:
Add all your classes to NSArray, and select the correct class by the indexPath.row.
- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSArray * conrollersClasses =#[[CallViewController class],[BirthdayViewController class]];
UIViewController *controller = [[conrollersClasses[indexPath.row] alloc] init];
[[self navigationController] controller animated:YES];
}
I want to pass selected row's text to another view's label. But this not work. Not pushing second view. How can I solve this problem?
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
SecondViewController *detailViewController = [[SecondViewController alloc] initWithNibName:#"SecondView" bundle:nil];
// ...
// Pass the selected object to the new view controller.
NSUInteger row2 = [indexPath row];
NSLog(#"rowden %i",row2);
denemelik=row2;
NSLog(#"kontrol %i",denemelik);
[self.navigationController pushViewController:detailViewController animated:YES];
detailViewController.stringdir= [ws2.CustomerName objectAtIndex:[indexPath row]];
NSLog(#"hoff %#", [ws2.CustomerName objectAtIndex:[indexPath row]]);
NSLog(#"kontrol2 %#",ws2.CustomerName);
[detailViewController release];
}
in my secondViewController.m viewDidLoad I set the 'stringdir' to label's text:
enyakinfirma.text = stringdir;
You just need to swap this 2 line of codes around
detailViewController.stringdir= [ws2.CustomerName objectAtIndex:[indexPath row]];
[self.navigationController pushViewController:detailViewController animated:YES];
You should set the value before calling the navigationController. At least that's what i am doing.
I added this method didSelectRowAtIndexPath to go to the next view
no errors but i can't go to the next view.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
detailhadith *detaihd = [[detailhadith alloc] initWithNibName:#"detailhadith" bundle:nil];
[self.navigationController pushViewController:detaihd animated:YES];
[detaihd release];
}
you can just add a subview like this: [self.view addSubview:nextView.view]; if you don't have a navigationController.
My root view contains three sections in a table view. Depending on which section is selected a corresponding view controller will be popped onto the view stack. The following didSelectRowAtIndexPath method is from my code and it works as I expect, but I was wondering if this is the correct/most elegant way to do it. I'm an Objective-C newcomer so I'm not sure if I should be intitializing the viewController to nil first.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UIViewController *viewController = nil;
if (indexPath.section == 0) {
viewController = [[FirstViewController alloc] initWithNibName:#"FirstViewController" bundle:nil];
}
else if (indexPath.section == 1) {
viewController = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil];
}
else if (indexPath.section == 2) {
viewController = [[ThirdViewController alloc] initWithNibName:#"ThirdViewController" bundle:nil];
}
[self.navigationController pushViewController:viewController animated:YES];
[viewController release];
}
You could do this in a swtch() statement, but otherwise, I think this is good. The only other change would be to check for a viewController before pushing:
if (viewController != nil) [self.navigationController pushViewController...
