我用故事板,我已经创建了一个UIScrollView和它的出口:使用的UIScrollView和Xcode 4.6

.h

@interface ViewController : UIViewController <UIScrollViewDelegate> 
    @property (strong, nonatomic) IBOutlet UIScrollView *scrollView; 
@end 

.m:我合成滚动视图,并在viewDidLoad中我有

- (void)viewDidLoad { 
[super viewDidLoad]; 
self.scrollView.delegate = self; 

// Init an array with 3 images 
subviewArray = [[NSMutableArray alloc] initWithObjects:@"image1.jpg", @"image2.jpg", @"image3.jpg", nil]; 

for (int i = 0; i < [subviewArray count]; i++) { 
    //We'll create a View object in every 'page' of our scrollView. 
    CGRect frame; 
    frame.origin.x = self.scrollView.frame.size.width * i; 
    frame.origin.y = 0; 
    frame.size = self.scrollView.frame.size; 

    UIImageView *imageView = [[UIImageView alloc] initWithFrame:frame]; 
    imageView.image = [UIImage imageNamed:[subviewArray objectAtIndex:i]]; 
    [self.scrollView addSubview:imageView]; 
} 

NSLog(@"%f", self.scrollView.frame.size.width); 

//Set the content size of our scrollview according to the total width of our imageView objects. 
self.scrollView.contentSize = CGSizeMake(self.scrollView.frame.size.width * [subviewArray count], self.scrollView.frame.size.height); 
} 

问题是当我打印“self.scrollView.frame.size.width”的值时,我得到“0”! 任何帮助PLZ!

您是否将滚动视图连接到插座? self.scrollView是否为? – Wain 2013-04-27 11:47:20

当然,我做过,当我不使用故事板时,它使用相同的逻辑! – raed 2013-04-27 12:14:32

你确认实例是在运行时设置的吗? – Wain 2013-04-27 12:41:13

修复它,我不得不取消选中文件检查器中的“使用AutoLayout”。非常感谢Wain!希望这可以帮助其他人。祝你好运 !
