No, you should move the UIImageView within the containing view using its frame.
No, you should move the UIImageView within the containing view using its frame. UIImageView will scale an image (by setting its bounds or frame) but not move it.
In that case just change the contectMode of UIImageView to UIViewContentModeScaleToFill (if aspect ratio is inconsequential) or UIViewContentModeScaleAspectFit (if you want to maintain the aspect ratio) In IB, this can be done by setting the Mode in Inspector. In code, it can be done as yourImageView. ContentMode = UIViewContentModeScaleToFill; In case you want to display the large image as is inside a UIImageView, the best and easiest way to do this would be to have the image view inside a UIScrollView.
That ways you will be able to zoom in and out in the image and also move it around. Hope that helps.
It doesn't sound like the MoveMe sample does anything like what you want. The PlacardView in it is the same size as the image used. The only size change done to it is a view transform, which doesn't effect the viewport of the image.As I understand it, you have a large picture, and want to show a small viewport into it.
There isn't a simple class method to do this, but there is a function that you can use to get the desired results: CGImageCreateWithImageInRect(CGImageRef, CGRect) will help you out. Here's a short example using it: CGImageRef imageRef = CGImageCreateWithImageInRect(largeImage CGImage, cropRect); UIImageView setImage:UIImage imageWithCGImage:imageRef; CGImageRelease(imageRef).
Thanks a lot. I have found a pretty simple solution that looks like this: CGRect frameRect = myImage. Frame; CGPoint rectPoint = frameRect.
Origin; CGFloat newXPos = rectPoint. X - 0.5f; myImage. Frame = CGRectMake(newXPos, 0.0f, myImage.frame.size.
Width, myImage.frame.size. Height); I just move the frame around. It happens that portions of that frame go out of the iPhone's view port, but I hope that this won't matter much.
There is a mask over it, so it doesn't look weird. The user doesn't totice how it's done.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
