In this post, I have mentioned about how to split a single UIImage into multiple parts,
Below written is a method that receives a UIImage object and the number of rows, number of columns as input and it returns an array of UIImage objects in NSMutableArray object.
-(NSMutableArray *)getImagesFromImage:(UIImage *)image withRow:(NSInteger)rows withColumn:(NSInteger)columns
{
NSMutableArray *images = [NSMutableArray array];
CGSize imageSize = image.size;
CGFloat xPos = 0.0, yPos = 0.0;
CGFloat width = imageSize.width/rows;
CGFloat height = imageSize.height/columns;
for (int y = 0; y < columns; y++) {
xPos = 0.0;
for (int x = 0; x < rows; x++) {
CGRect rect = CGRectMake(xPos, yPos, width, height);
CGImageRef cImage = CGImageCreateWithImageInRect([image CGImage], rect);
UIImage *dImage = [[UIImage alloc] initWithCGImage:cImage];
[images addObject:dImage];
xPos += width;
}
yPos += height;
}
return images;
}
