I am new in iPhone app development, so I have getting problem on image cropping.
I want to crop an image in rectangle shape, I google it and find some solution for that and using this code:
CGRect cropRect = CGRectMake(0, 0, 70, 70);
CGImageRef imageRef = CGImageCreateWithImageRect(self.OriginalImage, cropRect);
but I don't understand that how can I display imageRef into our view controller.
Please help me.
For cropping the image one thing is very important to know that if we want to crop image then we need to convert that image into CGImage after that we can do anything with that image. after cropping the image in result cropped image will be saved into the CGImageRef reference variable.
Now, if we want to add cgimage into any view then we need to convert it into UIImage. below we are provided the complete code:
I hope it will be helpful for you.
