iOS 图像处理 － 图像拼接

解决问题：将两个图像拼接在一起

前提：需要添加Framework：CoreGraphics.framework

源码：

- (UIImage *) combine:(UIImage*)leftImage :(UIImage*)rightImage {    CGFloat width = leftImage.size.width * 2;    CGFloat height = leftImage.size.height;    CGSize offScreenSize = CGSizeMake(width, height);        UIGraphicsBeginImageContext(offScreenSize);        CGRect rect = CGRectMake(0, 0, width/2, height);    [leftImage drawInRect:rect];        rect.origin.x += width/2;    [rightImage drawInRect:rect];        UIImage* imagez = UIGraphicsGetImageFromCurrentImageContext();        UIGraphicsEndImageContext();        return imagez;}
