ios - Create UIView with custom shape -


so wondering if there's way make uiview custom shape.

i'm trying make piano keyboard when user touches view delegate method responds playing noise. picture .png picture of key , transparent background.

thanks in advance.

you can't make uiview in shape of, say, triangle, can make view transparent, add non-transparent content it.

for example, make view background of png (with, assume, partially transparent areas) make transparent uiview , add image view it. better yet, use uiimageview in place.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
