Question

我不明白为什么我的项目不起作用。我可以打开窗口，但是scrollview不会滚动，这意味着我无法看到我的UI的底部。为什么？我阅读了类似问题的答案，但他们没有帮助我解决我的问题。

这是DETAILVC.H

@interface DetailVC : UIViewController {
IBOutlet UIImageView *iv_main, *iv_ratings;
IBOutlet UITextField *tf_name, *tf_dob, *tf_age, *tf_weight, *tf_height,*tf_birthplace;
IBOutlet UITextView *tv_description;
IBOutlet UIButton *but_movies, *but_edit;
IBOutlet UINavigationBar *navbar;
IBOutlet UIScrollView *scrollView;

}

@property (nonatomic, retain) IBOutlet UIImageView *iv_main, *iv_ratings;
@property (nonatomic, retain) IBOutlet UITextField *tf_name, *tf_dob, *tf_age, *tf_weight, *tf_height, *tf_birthplace;
@property (nonatomic, retain) IBOutlet UITextView *tv_description;
@property (nonatomic, retain) IBOutlet UIButton *but_movies, *but_edit;
@property (nonatomic, retain) IBOutlet UINavigationBar *navbar;
@property (nonatomic, retain) IBOutlet UIScrollView *scrollView;
@end

这是DETAILVC.M

 #import "DetailVC.h"

 @interface DetailVC ()

 @end

 @implementation DetailVC

 @synthesize iv_main, iv_ratings, tf_age, tf_birthplace, tf_dob, tf_height, tf_name, tf_weight, tv_description, but_edit, but_movies,navbar, scrollView;

 - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
    // Custom initialization
}
return self;


}

- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
scrollView.contentSize = CGSizeMake(320, 1000);

}

- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}

@end

Answer 1

UIScrollView的框架是否有可能与contentSize具有相同的大小？如果是，UIScrollView会认为它有足够的框架来显示所有内容。

Objective-c UIScrollView现在滚动，也不垂直或水平滚动
