iOS5 Nsurlconnection Asynchronous Connection implementation

Hot Wheels to achieve

Uiactivityindicatorview *activityview=[[uiactivityindicatorviewalloc] Initwithframe:cgrectmake (150,30, 100,100)];

[ActivityView Setbackgroundcolor:[uicolor Lightgraycolor]];

[Self.view Addsubview:activityview];

[ActivityView startanimating];

Nsurlrequest*request=[[nsurlrequest alloc]initwithurl:[nsurl urlwithstring:@ "http://www.youku.com/"];

Nsoperationqueue*operationqueue=[[nsoperationqueuealloc]init];

[Nsurlconnectionsendasynchronousrequest:request

Queue:operationqueue

completionhandler:^ (Nsurlresponse*urlresponce,nsdata*data,nserror*error)

{

if (Error)

{

NSLog (@ "error:\n%@", error);

return;

}

[ActivityView stopanimating];

NSData converted into NSString

nsstring* aStr = [[NSString alloc] Initwithdata:data encoding:nsasciistringencoding];

NSLog (@ "getdata%@", data);

NSLog (@ "result%@", aStr);

}

];

[Operationqueue release];

Asynchronous request

Nsurlrequest*urlrequest=[[nsurlrequest alloc]initwithurl:[nsurl urlwithstring:@ "http://www.youku.com/"];

Nsurlresponse*urlresponce=nil;

Nserror*error=nil;

Nsdata*data=[nsurlconnection sendsynchronousrequest:urlrequestreturningresponse:&urlresponceerror:& ERROR];

NSLog (@ "data%@", data);

if (Error) {

NSLog (@ "error%@", error);

Return

}
