ios - requestImageDataForAsset returns nil image data -

-

i've been stuck couple of days. i've bee trying image within call nil. these options used:

 let options = phimagerequestoptions()             options.deliverymode = .highqualityformat             options.resizemode = .none

i tried options set nil without luck. data got in info value passed block. 

[phimageresultisincloudkey: 0,   phimageresultdeliveredimageformatkey: 9999,   phimagefileurlkey: file:///var/mobile/media/dcim/100apple/img_0052.jpg,   phimageresultrequestidkey: 84,   phimageresultisdegradedkey: 0,   phimageresultwantedimageformatkey: 9999,    phimageresultisplaceholderkey: 0,   phimagefilesandboxextensiontokenkey:    64b47b046511a340c57aa1e3e6e07994c1a13853;00000000;00000000;0000001a;com.apple.app-sandbox.read;;00000000;00000000;0000000000000000;/private/var/mobile/media/dcim/100apple/img_0051.jpg]

i tried using requestimageforasset , got same result. thought using requestimagedataforasset i'll more control on data.

also, thought file exists in cloud, not phimageresultisincloudkey value set 0; otherwise, i'd download it.

by way, able smaller version of image predefined size of 200x200 inside view; however, when try larger version of it, nil. know image exists on phone higher res (i can see in photos app)

any appreciated.

i had similar issue , tried setting networkaccessallowed option on phimagerequestoptions object yes - seemed fix it. me issue images in cloud images on camera roll worked fine in cloud did not.

javascript - Create websocket without connecting -

-
is there way create websocket without connecting right away? far think var ws = new websocket("ws://ws.my.url.com"); creates , connects right away. i'd create socket, define callbacks, , connect once user clicks connect button. thanks no. creating websocket means you've created connection server (or started process of connecting). there no such thing creating websocket isn't connecting yet. you create object store configuration parameters , tell object connect when wanted to, though i'm not sure why that's better creating actual websocket when connect made. or create function setup work , call function later when user clicks connect button.
