sockets - Using NSHost in iOS -


i'm trying make socket server application in swift ios. found great example:

    let addr = "127.0.0.1"     let port = 4000      var host :nshost = nshost(address: addr)     var inp :nsinputstream?     var out :nsoutputstream?      nsstream.getstreamstohost(host, port: port, inputstream: &inp, outputstream: &out)      let inputstream = inp!     let outputstream = out!     inputstream.open()     outputstream.open()      var readbyte :uint8 = 0     while inputstream.hasbytesavailable {         inputstream.read(&readbyte, maxlength: 1)     }      // buffer uint8 array containing bytes of string "jonathan yaniv.".     outputstream.write("hello", maxlength: "hello".length)

i tried run code in xcode , said nshost didn't exist. googled , found nshost wasn't able ios. can use instead?

edit

i'm using cocoa async socket socket connections. can find here cocoaasyncscket

change getstreamstohost getstreamstohostwithname

change:

nsstream.getstreamstohost(host, port: port, inputstream: &inp, outputstream: &out)

to

nsstream.getstreamstohostwithname(addr, port: port, inputstream: &inp, outputstream: &out)

ruby - How do I merge two hashes into a hash of arrays? -

http://codepad.org/wmyzqlis i'd merge these 2 arrays: a = { :a => 'a', :b => 'b', :d => 'd' } b = { :a => '1', :b => 'b', :c => 'c' } into hash looks this: {:a => ["a", "1"], :b => ["b", "b"], :c => [nil, "c"], :d => ["d", nil] } this doesn't work: p a.merge(b) { |k, v1, v2| [v1, v2] } # {:c=>"c", :a=>["a", "1"], :b=>["b", "b"], :d=>"d"} it's because hash#merge call block duplicate keys. a = { :a => 'a', :b => 'b', :d => 'd' } b = { :a => '1', :b => 'b', :c => 'c' } hash[(a.keys|b.keys).map { |key| [key, [a.fetch(key, nil), b.fetch(key, nil)]] }] # => {:a=>["a", "1"], :b=>["b", "b"], :d=>["d", nil], :c=>...
