我是iPhone的新手开发者.

我想要合并两个图像并且只获得一个图像而UIImageView没有设置alpha.

这是我的代码.这段代码正在使用alpha,但我想要设置没有设置alpha.

mycode的: -

-(UIImage *)maskingImage:(UIImage *)image
{

    CGSize sizeR = CGSizeMake(200, 220);
   // UIImage *textureImage = [UIImage imageNamed:@"tt.png"];
    UIImage *textureImage =imgView2.image;



    UIGraphicsBeginImageContextWithOptions(sizeR, YES, textureImage.scale);
    [textureImage drawInRect:CGRectMake(0.0, 0.0, 200, 220)];

    UIImage *bottomImage = UIGraphicsGetImageFromCurrentImageContext();

    UIImage *upperImage = image;


    CGSize newSize = sizeR ;
    UIGraphicsBeginImageContext(newSize);
    [bottomImage drawInRect:CGRectMake(0.0, 0.0, 200, 220)];
    [upperImage drawInRect:CGRectMake(0.0, 0.0, 200, 220) blendMode:kCGBlendModeNormal alpha:0.5];



    UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return newImage; 
}

提前致谢.

我怎么能得到图像？

我已经使用以下代码获得标题或描述.

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{

    if([elementName  isEqualToString:className])
