Incompatible integer to pointer conversion assigning to 'CGFloat *' (aka 'float *') from 'int'

Question

I'm having a problem with CGFloat. What I am trying to do is to set a value for the X of a UIScrollView to do some actions when the user change page using a UIButton to do that.

This is the error Xcode gives to me:

Incompatible integer to pointer conversion assigning to 'CGFloat *' (aka 'float *') from 'int'

This is my code:

.h

#import <UIKit/UIKit.h>

@interface MenuViewController : UIViewController <UIScrollViewDelegate>
{

}

@property (nonatomic)                       CGFloat         *offsetPoint;
@property (weak, nonatomic)     IBOutlet    UIScrollView    *trackSelectionScrollView;

@end

.m

- (void)scrollForward
{
    self.offsetPoint = self.trackSelectionScrollView.contentOffset.x; // Error here

    if ((self.offsetPoint = 0)) // Error here
    {
        [self.trackSelectionScrollView setContentOffset:CGPointMake(320, 0) animated:YES];
    }

    if ((self.offsetPoint = 320)) // Error here
    {
        [self.trackSelectionScrollView setContentOffset:CGPointMake(640, 0) animated:YES];
    }

    if ((self.offsetPoint = 640)) // Error here
    {
        //Last page do nothing
    }
}

If you can't understand the problem with the code I've posted I will post more of it :-)

Answer 1

@property (nonatomic) CGFloat *offsetPoint;

This property is storing a pointer to a float and it shouldn't be. Change it to:

@property (nonatomic) CGFloat offsetPoint;
