Im trying to integrate implement the project https://github.com/ariok/BWWalkthrough into my objective c project.
I have an objc bridging header that Xcode automatically made for me
I translated the ViewController.swift code as such
UIStoryboard *sb = [UIStoryboard storyboardWithName:#"Walkthrough" bundle:nil];
BWWalkthroughViewController *walkthrough = [sb instantiateViewControllerWithIdentifier:#"walk"];
BWWalkthroughPageViewController *page_zero = [sb instantiateViewControllerWithIdentifier:#"walk0"];
BWWalkthroughPageViewController *page_one = [sb instantiateViewControllerWithIdentifier:#"walk1"];
BWWalkthroughPageViewController *page_two = [sb instantiateViewControllerWithIdentifier:#"walk2"];
BWWalkthroughPageViewController *page_three = [sb instantiateViewControllerWithIdentifier:#"walk3"];
walkthrough.delegate = self;
[walkthrough addViewController:page_zero];
[walkthrough addViewController:page_one];
[walkthrough addViewController:page_two];
[walkthrough addViewController:page_three];
[self presentViewController:walkthrough animated:YES completion:nil];
and I import the swift classes like so:
import "SkipTheLine-Swift.h"
My bridging header file's name is "SkipTheLine-Bridging-Header.h"
now, when I run the code, I get this
2015-04-25 16:47:46.740 SkipTheLine[1631:215786] Unknown class BWWalkthroughViewController in Interface Builder file.

Any ideas as to how I can use the swift code in interface builder?
Figured it out!
You just need to edit the MODULE in the interface builder to the name of the project!!

I'm trying to pass data from my ViewController to TabBarController by using Objective-C. I'm trying to assign some data to "bottomTabEventList" (which is a property of my custom TabBarController class). Unfortunately, my program crashes by giving unrecognized selector instance error/warning.
In custom header of TabBarController class, named BottomTabview:
#interface BottomTabView : UITabBarController <UITabBarControllerDelegate>
#property(strong,nonatomic)EventList *bottomTabEventList;
#end
And prepareForSegue method in ViewController.m
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
BottomTabView *btw = [segue destinationViewController];
//checking
if(btw == nil)
NSLog(#"btw in viewController is nil");
else
NSLog(#"btw in viewController is NOT nil");
if(self.eventList.eventList == nil)
NSLog(#"eventList in viewController is nil");
else
NSLog(#"eventList in viewController is NOT nil"); //end of checking
btw.bottomTabEventList = self.eventList; //This is where crash appears
}
Exact crash log is:
-[ViewController setBottomTabEventList:]: unrecognized selector sent to instance 0x7fe923c6ba00
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[ViewController setBottomTabEventList:]: unrecognized selector sent to instance 0x7fe923c6ba00'
Segue is from ViewController to BottomTabView and its type is "Present Modally". I'd really appreciate if you can help/guide me. Thanks in advance.
The problem seems to be that btw is not actually of type BottomTabView and is just a UIViewController hence the crash log giving:
[ViewController setBottomTabEventList:]: unrecognized selector sent to instance
As UIViewController does't know what BottomTabEventList is.
You need to make sure that btw is actually a BottomTabView instance.
Do a little introspection and I bet it will not go into this statement:
if ([btw isKindOfClass:[BottomTabView class]]){
btw.bottomTabEventList = self.eventList;
}
I get this error:
-[MPInlineVideoFullscreenViewController player]: unrecognized selector sent to instance 0x15e63fe90
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MPInlineVideoFullscreenViewController player]: unrecognized selector sent to instance 0x15e63fe90'
Using iOS 8, the language is Objective-C. But I have this same code in the if statement like this in applicationDidBecomeActive and it does not crash:
UIViewController *vc = ((UINavigationController*)self.window.rootViewController).visibleViewController;
if([vc isKindOfClass:[VideoViewController class]]) {
VideoViewController *vca = vc;
if(vca.player.playbackState == MPMoviePlaybackStatePaused){
[vca.player play];
}
But if I use it on the different MPMoviePlayer, and it is fullscreen. I switch to a different app, and back, it crashes. Buy why not with the other movie controller. Also, the other one does not show any playback controls, while this one which crashes does.
I am trying to get a pop up menu on iPhone.
The main app is using storyboard, but the pop up is a separate xib file that I load:
menu = [[UIViewController alloc] initWithNibName:#"SimpleMenuController" bundle:nil];
[self.view addSubview:menu.view];
and I slide it in and out with animation when pressing a button.
that works fine, but I get a problem when I try to press a button inside that pop up menu
I get the following error:
Terminating app due to uncaught exception 'NSInvalidArgumentException',
reason: '-[UIViewController PressCategory:]:
unrecognized selector sent to instance 0x8d3c040'
I have connected the button to PressCategory function
I have connected the view to the file owner.
What I have noticed is that my ViewController is called SimpleMenuViewController, that is where the PressCategory function is, so of course it will not find the selector. But I don't know what I am doing wrong in connecting in the xib file.
Change your code to:
menu = [[SimpleMenuViewController alloc] initWithNibName:#"SimpleMenuController" bundle:nil];
so that you're instantiating the correct class.
Do you have PressCategory function in your SimpleMenuViewController?
If yes, then check weather its parameterized or not.
Declare function in .h file like this:
-(IBAction)PressCategory:(UIButton *)sender;
Define it in .m file like this:
-(IBAction)PressCategory:(UIButton *)sender {
// write your code here
}
I am getting this exception:
2012-10-11 14:27:05.039 SunriseAlarm[2297:907] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[PickerViewController _setViewDelegate:]: unrecognized selector sent to instance 0x1e56fff0'
I have this code in the appDelegate.m file
PickerViewController *pvc = [[PickerViewController alloc] initWithNibName:#"PickerView" bundle:nil];
self.window.rootViewController = pvc;
I have already set the class of the nib to the custom class and it is not UIViewController. Please see image below.
Please let me know what do you think I am doing wrong.
Thank You,
Venkat Rao
You did set PickerViewController class for UIView, it's not correct, return back and set PickerViewController for File's owner

The error complains on this line of code:

The error appears only on my iPhone but not on the simulator...
You must uncheck the box in your NIB that says "use auto layout" before you try to run this thing on a device that doesn't support the new NSLayoutConstraint class.
