IOS設置View的背景圖片

//  設置View的背景
    UIImageView *imgView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"bg_bg"]];
    imgView.frame = self.view.bounds;
    imgView.autoresizingMask = UIViewAutoresizingFlexibleWidth;
    [self.view insertSubview:imgView atIndex:0];

//    設置View的背景顏色，使用圖片，效果和設置背景圖片比較類似(個人更喜歡這種方法)
    [self.view setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"bg_bg"]]];

//   設置UITableView的背景view
    UIImageView *imgView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"bg_bg"]];
    imgView.frame = self.view.bounds;
    imgView.autoresizingMask = UIViewAutoresizingFlexibleWidth;
    [self.view setBackgroundView:imgView];
