I need to create an app which features a login/signup form and then a custom Google Map. I am new to iOS programming and trying to learn the things needed for this app very fast.
So, I have created the frontend and the backend of the login form, it works. I have an action which is triggered by the "Log in" button which verifies the credentials and either trigger a error either presents the Google Map.
I want to show that Google Map in another view controller which controls another xib file. I created the view controller and the xib file.
My question is how can I load another view controller from an action placed in the implementation file of the current view controller?
Now, I have this code:
UIViewController *mapViewController =
[[BSTGMapViewController alloc] initWithNibName:@"BSTGMapViewController"
bundle:nil];
How can I make it the "root view controller" of the window and maybe featuring a transition (considering my logic is ok)?
If you want to open the ViewController
from another one then you should define it like this in your IBAction
. It is good idea to make the viewController
as property though.
FirstViewController.h
@class SecondViewController;
@interface FirstViewController : UIViewController
@property(strong,nonatomic)SecondViewController *secondViewController;
@end
FirstViewController.m
-(IBAction)buttonClicked:(id)sender{
self.secondViewController =
[[SecondViewController alloc] initWithNibName:@"SecondViewController"
bundle:nil];
[self presentViewController:self.secondViewController animated:YES completion:nil];
}
You should make a viewController as rootViewController
in your AppDelegate
class something like this
YourFirstViewController *firstViewController=[[YourFirstViewController alloc]initWithNibName:@"YourFirstViewController" bundle:nil];
self.window.rootViewController=yourFirstViewController;
