// 调用系统照片库

// 将view视图保存到照片库中
+ (void)saveViewToPhotosAlbum:(UIView *)view

        UIGraphicsBeginImageContext(view.layer.bounds.size);
        [view.layer renderInContext:UIGraphicsGetCurrentContext()];

        UIGraphicsEndImageContext();
        UIImageWriteToSavedPhotosAlbum(viewImg, nil, nil, nil);
