问题描述

所以，我知道我有类似的问题，但可能不准确(所以请不要标记我——只是警告我或其他什么).我已经搜索了几天来解决这个简单的问题.使用故事板、ARC 和 Xcode 4.5.2，我只需将一堆标签放在 UIScrollView 中并让它垂直滚动.我已经尝试过在 viewDidLoad、viewDidAppear 和 viewWillAppear 中设置帧大小和内容大小的多种组合，但无济于事.当里面没有任何东西时，滚动视图可以完美滚动，但是当我给它添加标签时，滚动只会滚动很短的部分.

So, I know there are similar questions to mine, but maybe not exact (so please don't mark me down -- just warn me or something). I have searched for days for the solution to this SIMPLE issue. Using storyboards, ARC, and Xcode 4.5.2, I simply need to put a bunch of labels inside a UIScrollView and have it scroll vertically. I've tried so many combinations of setting frame sizes and content sizes within viewDidLoad, viewDidAppear, and viewWillAppear, but to no avail. The scroll view scrolls perfectly when there's nothing inside of it, but when I add labels to it, the scrolling only scrolls a very short section.

注意:我需要使用自动布局，否则我的整个项目都会搞砸.

Note: I need to use auto layout, otherwise my whole project will get messed up.

这是我当前的代码...

Here's my current code...

.h 文件:

#import <UIKit/UIKit.h>

@interface MortgageRatesViewController : UIViewController <UIScrollViewDelegate, UIScrollViewAccessibilityDelegate>

- (IBAction)backButton:(id)sender;

@property (strong, nonatomic) IBOutlet UIView *mortgageView;

@property (weak, nonatomic) IBOutlet UIScrollView *scrollView;

@end

.m 文件:

#import "MortgageRatesViewController.h"


@interface MortgageRatesViewController ()

@end

@implementation MortgageRatesViewController

- (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.

    self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"appBackgroundColor.png"]];


    [self.scrollView setScrollEnabled:YES];
    [self.scrollView setContentSize:CGSizeMake(0, 809)];



}

//---------------------------------------------------------------

//---------------------------------------------------------------

//-(void)viewWillAppear:(BOOL)animated{
//    
//    
//    [super viewWillAppear:animated];
//    
//    
//    [self.scrollView setFrame:CGRectMake(0, 0, 320, 808)];   
//
//
