implement iphone code for a stream url request

Project Description:
Implement iphone objective c code (the code will be used in my iOS project.) to request the following url and get result,

http://streamerapi.finance.yahoo.com/streamer/1.0?s=MSFT,GOOG&k=l10,c10,p20,g00,h00\&callback=parent.yfs_u1f&mktmcb=parent.yfs_mktmcb&gencallback=parent.yfs_gencb

It's a stream url, I tried it on web browser, but cannot return any result. The only way to get result is to run curl on command line by:
curl -s -o - -N 'http://streamerapi.finance.yahoo.com/streamer/1.0?s=MSFT,GOOG&k=l10,c10,p20,g00,h00\&callback=parent.yfs_u1f&mktmcb=parent.yfs_mktmcb&gencallback=parent.yfs_gencb'

This command will return real-time stock information and keep streaming new result.

Now we need to make it work in iphone app also. More specifically, write a objective c code to request the url and listen to the stream, output result when new information is pushed. No need for UI, just the original functions.

the url should be, the previous one is not correct

http://streamerapi.finance.yahoo.com/streamer/1.0?s=MSFT,GOOG&k=l10,c10,p20,g00,h00&callback=parent.yfs_u1f&mktmcb=parent.yfs_mktmcb&gencallback=parent.yfs_gencb
