Just try [self.navigationController popViewControllerAnimated:YES];
Inherited view controller will not dismiss itself in a block #ICETutorial
Pergunta
I'm using ICETutorial with cocoapods.
I'm using it in a SettingsViewController where you can view the tutorial in settings.
// SettingsViewController.m
Tutorial2ViewController *vc = [[Tutorial2ViewController alloc] init];
[self.navigationController setNavigationBarHidden:YES animated:NO];
[self.navigationController pushViewController:vc animated:NO];
And Tutorial2ViewController
inherits from ICETutorialController
@interface Tutorial2ViewController : ICETutorialController
ICETutorialPages have buttons that will trigger a callback. It takes in a block. So in my implementation, I have this:
- (id)init
{
ICETutorialPage *layer1 = [[ICETutorialPage alloc] initWithSubTitle:@"Page 1" description:@"Page 1" pictureName:@"Tutorial1_640x1136.png"];
NSArray *tutorialLayers = @[layer1];
self = [super initWithNibName:@"ICETutorialController_iPhone" bundle:nil andPages:tutorialLayers];
__weak Tutorial2ViewController *vc = self;
[self setButton1Block:^(UIButton *button){
NSLog(@"Button 1 pressed.");
[[vc.navigationController topViewController] dismissViewControllerAnimated:NO completion:nil];
}];
if (self != nil)
{
}
return self;
}
The reason why I put all the code in init is that I don't want SettingsViewController
to know anything about how the Tutorial2ViewController
works. Settings should alloc and init, push to the navigation controller stack and the Tutorial2ViewController
should know how to handle itself.
I do get the NSLog that button1 is pressed but the view controller does not dismiss itself and return me to the SettingsViewController.
I will contact the creator of the library and ask him/her to see this question also. I feel that this is me not misunderstanding blocks, navigation controllers, cocoapods, etc...
Thanks
