1.uiscrollview 设置背景图片

// Setup the Scroll View
UIScrollView*tempScrollView=(UIScrollView*)self.view;
tempScrollView.contentSize=CGSizeMake(320,720);

// Set Stationary Background, so that while the user scroll the background is
// fixed.
UIImage*img =[UIImage imageNamed:@"bg-body.jpg"];
[tempScrollView setBackgroundColor:[UIColor colorWithPatternImage:img]];

2. uiview 设置背景图片

self.view.backgroundColor = [UIColor colorWithPatternImage: [UIImage imageNamed:@"1.jpg"] ];

3. 个要比较推荐下面几种

在uiview设置背景图片

UIImageView* bgview = [[UIImageView alloc]initWithImage:TTIMAGE(@"bundle://uiscrollviewbg1.jpg")];
bgview.frame = CGRectMake(0, 0, scrollView.frame.size.width, scrollView.frame.size.height);
[self addSubview:bgview];
[bgview release];

在uiscrollview设置背景图片

UIImageView* bgview = [[UIImageView alloc]initWithImage:TTIMAGE(@"bundle://uiscrollviewbg.png")];
bgview.frame = CGRectMake(0, -100, 320, 100);
[_scrollView addSubview:bgview];
[bgview release];
