I used the tabview setup to create an app that has several tabs. One tab has a UIScrollView on it which loads 12 different views into 12 pages. I tried adding a button and imageview to one of the views and now it crashes. I’ve pored over every single question on here I can find, and have tried every suggested solution, but to no avail. The error that I get is the famous “this class is not key value coding-compliant for the key foo” error. As with everyone else who had this problem, if I disconnect the outlet, it works fine. I’ve checked and rechecked the class for the nib and it points to the right place.<\/p>\n

So I’m not even sure where to go next.<\/p>\n

I could post some code, but I don’t even know what code would be helpful to post. I’m hoping someone just says, “Um yeah, you can’t have a scroll view with multiple views in it and expect to have functionality on each page.” That would be helpful!<\/p>\n

Page2.h:<\/p>\n

#import \n<\/code><\/pre>\n
@interface Page2 : UIViewController {<\/p>\n
IBOutlet UIImageView *infoImage;\n<\/code><\/pre>\n
}<\/p>\n
@property (retain, nonatomic) UIImageView *infoImage;<\/p>\n
    \n
  • (IBAction) showInfo:(id)sender;<\/li>\n<\/ul>\n
    @end<\/p>\n
    Page2.m:<\/p>\n
    - (IBAction)showInfo:(id)sender {\n\n\/\/ do something please!\n<\/code><\/pre>\n
    }<\/p>\n
    Then in the nib file I CTRL-dragged from “touch-up inside” on my button to the Files Owner and chose “showInfo” … and I CTRL-dragged from Files Owner down to my UIImageView and chose infoImage.<\/p>\n
    CRASH<\/p>\n
