I want to add something like this as a RAC extension:
- (RACSignal *)resizeWithAspect:(RACSignal *)maxSize
{
return [[self combineLatestWith:maxSize] map:^id(RACTuple *tuple) {
RACTupleUnpack_(NSValue *oldSize,NSValue *maxSize) = tuple;
CGSize newSize = AVMakeRectWithAspectRatioInsideRect(oldSize.med_sizeValue, CGRectWithSize(maxSize.med_sizeValue)).size;
return MEDBox(newSize);
}];
}
edit here's another possibility:
- (RACSignal *)resizeWithAspect:(RACSignal *)maxSize
{
return [RACSignal combineLatest:@[self,maxSize] reduce:^id(NSValue *currentSize,NSValue *maxSize) {
CGSize newSize = AVMakeRectWithAspectRatioInsideRect(currentSize.med_sizeValue, CGRectWithSize(maxSize.med_sizeValue)).size;
return MEDBox(newSize);
}];
}
Thoughts?

A method like that would be useful, but we can't introduce a dependency on AVFoundation.
If you're willing to rewrite the sizing algorithm from scratch, I'd be happy to review a PR.

Yeah, I tried to find the actual implementation, but of course avfoundations m files are a tightly guarded secret. I'll try to come up with something equivalent.

In that case, let's leave this open until a PR is merged that completes it.

Instead of targeting CGSize
, perhaps a better approach would be to mirror the syntax of UIViews contentMode
. A signal with a name similar to UIViewContentModeScaleAspectFit
like -(RACSignal *)scaleAspectFit:(RACSignal *)maxRect]
. I'll push something based on that concept.

First things first. Submitting pull request to Archimedes for the functions themselves.
Then a special RACSignal should be added to use them.
