UIScrollView与大图

Question

此代码显示scrollView，但我想要显示的图像（教程）比视图大。换句话说，tutorial.png正好是280X1200，但它不会使用aspectFit。我想的东西这里小：

tipScroll = [[UIScrollView alloc]initWithFrame:CGRectMake(20, 10, 280, 1200)]; 
tipScroll.showsVerticalScrollIndicator = YES; 
tipScroll.scrollEnabled = YES; 
tipScroll.userInteractionEnabled = YES; 

UIImageView *tutorialImageView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"tutorial"]]; 

tipScroll.contentMode = UIViewContentModeScaleAspectFit; 
tutorialImageView.contentMode = UIViewContentModeScaleAspectFit; 

tipScroll.contentSize = tutorialImageView.frame.size; 

[self.view addSubview:tipScroll]; 
[tipScroll addSubview:tutorialImageView];

请看下面编辑code.It将工作

tipScroll = [[UIScrollView alloc]initWithFrame:CGRectMake(20, 10, 280, 1200)]; 
tipScroll.showsVerticalScrollIndicator = YES; 
tipScroll.scrollEnabled = YES; 
tipScroll.userInteractionEnabled = YES; 

UIImageView *tutorialImageView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 280, 1200)]; 
tutorialImageView.image = [UIImage imageNamed:@"tutorial"]; 

tipScroll.contentSize = tutorialImageView.frame.size; 
[tipScroll addSubview:tutorialImageView]; 
[self.view addSubview:tipScroll];
