【原】给UIview添加背景图片最简单方法

在viewDidLoad里面添加：  

[self.view setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"11.jpg"]]];

就是这么简单

也可以另设一个UIImageView，把图片放上去，再把UIImageView 作为子视图添加上去：

- (void)setBackgroundImage {
    NSLog(@"setting bg image");
    UIImageView *customBackground = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"background.jpg"]];
    self.background = customBackground;
    [customBackground release];

    [self addSubview:background];
    NSLog(@"Added background subview %@", background);
    [self sendSubviewToBack:background];
}
