A. IDViewController的背景资料
原标题:Background Watermark type image for UIViewController

我试图树立一个形象,作为主谈的背景,这里我是如何做到的:

UIImage *bgImage = [UIImage imageNamed:@"watermark.png"];
self.view.layer.contents = bgImage.CGImage;
self.view.backgroundColor = [UIColor clearColor];

这一工作在SiOS5进行,但在SOS4进行,所有我都有一个黑背景。 任何想法?

我尝试了其他办法,如彩色色谱法,但这种方式没有适当展示形象。

问题回答

修改第二行如下:

self.view.layer.contents = (id)bgImage.CGImage;

你可以尝试这样做。

UIImageView *backgroundImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"your_image.png"]];
[self.view addSubview:backgroundImage];
[self.view sendSubviewToBack:backgroundImage];
[backgroundImage release];

在此情况下,你可以按照目前的观点管理观点,并将<编码>UIImageView。 希望会有所助益。

我认为,所有东西都是冰和大韩民国,只是用于你的手机cellForAtIndexpath

 UIImage *bgImage = [UIImage imageNamed:@"watermark.png"];
 UIImageView *imageView = [[UIImageView alloc] initWithImage:bgImage];
 [cell.contentView addSubview: imageView];
