解決這個問題:將兩個影象拼接在一起
前提:須要加入Framework:CoreGraphics.framework
原始碼:
- (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;
}
