[摘抄］iphone开发秘籍里面的捕捉屏幕截图代码

+ (UIImage *) imageFromView: (UIView *) theView

{

//Draw a view`s contents into an image context

UIGraphicsBeginImageContext(theView.frame.size);

CGContextRef context = UIGraphicsGetCurrentContext();

[theView.layer renderInContext:context];

UIGraphicsEndImageContext();

return theImage;

}

－－此函数要用到QuartzCore.framework框架
