One, synchronous GET request method

-(void) Synchronizationget

{

nsstring *strurl = @ "http://olasapi.sinaapp.com//index.php";

nsurl *url = [nsurl urlwithstring: strURL];

nsurlrequest *request = [[nsurlrequest alloc] initwithurl: url];

nsdata *data = [nsurlconnection sendsynchronousrequest: Request Returningresponse :nil error:nil];

NSLog(@ " request complete ");

nsdictionary *dic = [nsjsonserialization jsonobjectwithdata:d ata options: nsjsonreadingallowfragments error:nil];

NSLog(@ "%@", dic);

}

Second, asynchronous get

-(void) Asynchronousget

{

nsstring *strurl = @ "http://olasapi.sinaapp.com//index.php";

nsurl *url = [nsurl urlwithstring: strURL];

nsurlrequest *request = [[nsurlrequest alloc] initwithurl: url];

nsurlconnection *connection = [[nsurlconnection alloc] initwithrequest: Request Delegate:self];

if (connection) {

_data = [nsmutabledata new];

}

}

#pragma mark-nsurlconnection callback method

-(void) connection: (nsurlconnection *) connection didreceivedata: (nsdata *) data

{

[_data appendData:d ATA];

}

-(void) connection: (nsurlconnection *) connection didfailwitherror: (nserror *) Error

{

}

-(void) connectiondidfinishloading: (nsurlconnection *) connection

{

NSLog(@ " request complete ");

nsdictionary *dic = [nsjsonserialization jsonobjectwithdata:_data options: nsjsonreadingallowfragments error:nil];

NSLog(@ "%@", dic);

}

Three, asynchronous post

-(void) Asynchronouspost

{

nsstring *strurl = @ "http://olasapi.sinaapp.com//index.php";

nsurl *url = [nsurl urlwithstring: strURL];

nsmutableurlrequest *request = [[nsmutableurlrequest alloc] initwithurl: URL ];

[Request Sethttpmethod:@ "POST"];

[Request sethttpbody:@ "]

nsurlconnection *connection = [[nsurlconnection alloc] initwithrequest: Request delegate:self];

if (connection) {

_data = [nsmutabledata new];

}

}
