Question

im working on a old code and i have this warning message:
Passed-by-value struct argument contains uninitialized data (e.g., via the field chain: ‘origin.x’). If i could get dome help i would be very thankful 🙂

The code im using:

- (void)positionScroller
{
    CGRect screenFrame = [[UIScreen mainScreen] bounds];
    CGRect scrollerRect;

    if( self.interfaceOrientation == UIInterfaceOrientationPortrait || self.interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown )
    {
        scrollerRect = CGRectMake( 0, 0, screenFrame.size.width, screenFrame.size.height );
    }
    else if( self.interfaceOrientation == UIInterfaceOrientationLandscapeLeft || self.interfaceOrientation == UIInterfaceOrientationLandscapeRight )
    {
        scrollerRect = CGRectMake( 0, 0, screenFrame.size.height, screenFrame.size.width );
    }

    _scroller.frame = scrollerRect;   <---This is where the compiler gives the warning
}

Best Regards.

You can easily get rid of the warning like this:

- (void)positionScroller 
{ 
    CGRect screenFrame = [[UIScreen mainScreen] bounds]; 
    CGRect scrollerRect; 

    if( self.interfaceOrientation == UIInterfaceOrientationPortrait || self.interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown ) 
    { 
        scrollerRect = CGRectMake( 0, 0, screenFrame.size.width, screenFrame.size.height ); 
    } 
    else  
    { 
        scrollerRect = CGRectMake( 0, 0, screenFrame.size.height, screenFrame.size.width ); 
    } 

    _scroller.frame = scrollerRect;   <---This is where the compiler gives the warning 
}
