ios - Detect device rotation inside a collectionViewCell -

-



inside custom collectionvirewcell create gradient layer , add cell in function override func awakefromnib() {}

 self.layer.insertsublayer(gradient, at: 0)

when device rotates size of cell changes not size of layer. need 

override func viewdidlayoutsubviews() {     gradient.frame = self.bounds

}

the problem error telling me viewdidlayoutsubviews() did not override function superclass. there method detect cell size variation inside cell class?

viewdidlayoutsubviews() uiviewcontroller method , not method of uiview uicollectionviewcell inherits from.

the method you're looking override layoutsubviews()

override func layoutsubviews() {     <#code#> }

i think that's problem!

python - Read npy file directly from S3 StreamingBody -

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki
