Iphone Can'；不添加UIImageView？

我尝试在

UIScrollView

这是我的.h

@interface NormalDetail : UIViewController <UIScrollViewDelegate> {   
    IBOutlet UIImageView *lineImg;
}

@property (nonatomic, retain) UIImageView *lineImg;

@end

我的代码有什么问题，我的照片没有出现。请帮帮我；（

您需要将UIImageView转换为SCORLView

- (void) setupTextView
{
    textDescription.scrollEnabled = NO;
    NSString *foo = @"Hello Test";
    textDescription.text = foo;
    /*Here is something for dynamic textview*/
    CGRect frame;
    frame = textDescription.frame;
    frame.size.height = [textDescription contentSize].height;
    textDescription.frame = frame;
     /**/

    int linePosition = frame.size.height+20;
    lineImg = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"line.png"]];
    CGRect line2Frame = CGRectMake(-8, 600, 328, 10);
    lineImg.frame = line2Frame;

     //Add the image view as a subview to yout scrollview.
    [scrollView addSubView:lineImg];
}

并且仅当您在xib中添加了对象时才使用

IBOutlet

。当您使用

IBOutlet

时，将其用作`IBOutlet Class*ObjectName；`进行声明。并将属性创建为

@属性（非原子，保留）IBOutlet Class*ObjectName；

并且不要忘记用xib绑定对象。不，在本例中不是。代码不使用.syntax访问属性。

- (void) setupTextView
{
    textDescription.scrollEnabled = NO;
    NSString *foo = @"Hello Test";
    textDescription.text = foo;
    /*Here is something for dynamic textview*/
    CGRect frame;
    frame = textDescription.frame;
    frame.size.height = [textDescription contentSize].height;
    textDescription.frame = frame;
     /**/

    int linePosition = frame.size.height+20;
    lineImg = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"line.png"]];
    CGRect line2Frame = CGRectMake(-8, 600, 328, 10);
    lineImg.frame = line2Frame;

     //Add the image view as a subview to yout scrollview.
    [scrollView addSubView:lineImg];
}
