将UIImage从一个类发送到另一个类

Question

我想将UIImage从一个类发送到另一个类.在FirstViewController.mi中编写了这段代码

 FormViewController *formViewController =[[FormViewController alloc]initWithNibName:@"FormViewController" bundle:nil];
formViewController.userImage=imageFb;
    [formViewController.userImage retain];
 [self presentModalViewController:formViewController animated:YES];

错误是

成员'userImage'的请求不是结构或联合

在FormViewController.h中

@interface FormViewController : UIViewController
{
    UIImageView *photo;
    UIimage *userImage;

}
@property(retain,nonatomic)  UIimage *userImage;
@property(retain,nonatomic) IBOutlet UIImageView *photo;   

我得到这个错误

UIimage之前的预期说明符限定符列表

在FormViewController.m中

- (void)viewDidLoad
{
[super viewDidLoad];
    [photo setImage:userImage];
}

而错误是

userImage unclared(首次在此函数中使用)

Answer 1

这UIImage,不是UIimage.
