Question

I’m a real noob to objective C but I CANNOT figure out how to push transition from one view to another on a button click.

What I’m doing wrong here? I’ve #imported my Page2.h file in the header

I get these two errors

1 “unexpected interface name ‘Page2’: expected expression”

2 “No known Class method for selector ‘setFrame’

- (IBAction)Page2Switcher:(id)sender {

    CGRect inFrame = [_Page1 frame];
    CGRect outFrame = Page2;
    outFrame.origin.x -= inFrame.size.width;

    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:1.0];

    [Page2 setFrame:inFrame];
    [_Page1 setFrame:outFrame];

    [UIView commitAnimations];

}

Answer 1

Here is a glaring inconsistency:

1. From the line: CGRect outFrame = Page2; you must have that Page2 is of type CGRect, but this probably is not the case. Figure out what type Page2 is and how to get a CGRect from it. Most likely, Page2 is a UIView and you want to call [Page2 frame] instead.

2. From the line: [Page2 setFrame:inFrame];, you must have that Page2 is some object that has a frame property, e.g. a subclass of UIView. This is inconsistent with 1 above where Page2 is of type CGRect.
