1.设置图片大小自适应的背景图

UIImage *img_m = [UIImage imageNamed:@"login.jpg"];

UIImage *img_a;

CGFloat width = self.view.frame.size.width;

CGFloat height = self.view.frame.size.height;

UIGraphicsBeginImageContext(CGSizeMake(width, height));

[img_m drawInRect:CGRectMake(0, 0, width, height)];

img_a = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

self.upDownView.backgroundColor = [UIColor colorWithPatternImage:img_a];

1.uiscrollview设置背景图片

//Setup the ScrollViewUIScrollView*tempScrollView=(UIScrollView*)self.view;tempScrollView.contentSize=CGSizeMake(320,720); //Set Stationary Background, so that whilethe user scroll the backgroundis //fixed.UIImage*img =[UIImage imageNamed:@"bg-body.jpg"];[tempScrollView setBackgroundColor:[UIColorcolorWithPatternImage: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); [selfaddSubview: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];
