iphone - Detecting touches for layers within a UIScrollView -

-

i have uiscrollview contains number of thumbnails should detect touch event, perform 3d transformation on , call delegate method.

the 1 problem unable overcome detecting sublayer being tapped. setting layer.name index count , subclass of uiscrollview touch event. last remaining obstacle how hittest on sublayers name property , voila!

i thinking of subclassing uiview container of calayer , capturing touch event way. hoping there might more economical way determine sublayer being touched.

the code have been trying (in uiscrollview subclass):

-(void)touchesbegan:(nsset *)touches withevent:(uievent *)event {     if ([touches count] == 1) {         (uitouch *touch in touches) {              cgpoint point = [touch locationinview:[touch view]];             calayer *alayer = [self.layer hittest:point];             if (alayer) nslog(@"layer %@ touched",alayer.name);             else nslog(@"layer not detected");          }      }  }

i getting 2 compile errors. first warning: no hittest method found. , error "request member 'name' not structure or union".

call [scrollview.layer hittest:touchpoint];. return value layer touched. if returned layer equal scrollview.layer, no sublayer tapped.

i'm trying create application adheres following: no taskbar no console or form window can utilize console.writeline() .

i'm trying load particular private key encoded in binary der format ( pkcs#8 ) ruby. however, openssl::pkey won't recognize it. can make work doing console work , transforming pem so: openssl pkcs8 -inform der -in file.key -passin pass:xxxxxxxx >private_key.pem after this, key can correctly read. however, since whole process done in memory instead of writing , reading files. so question is: possible load private keys binary encoded der format ruby/openssl? thank time, fernando yes, can indirectly load pkcs#8 der-encoded private keys using ruby openssl. openssl::pkey::rsa.new handle pem-formatted pkcs#8, easy read binary der , convert pem-formatted string , load string. for example, these der-encoded private keys: $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -nocrypt -out pkcs8.key $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -v2 des3 -passout pass:secret -out pkcs8_des3.key you can this: require 'open...
