Learn the iphone development for some time, for me this novice, learning process, encountered a lot of problems, especially webservice call has been plagued for a long time, in the eve of the singles, talk about the personal problems encountered in WebService and solutions ~ ~ To share with you, For those who can skip over ~ ~

Also do not know this is the first few Singles Day in life, no sister, very tangled, did not meet the person, in the love of the waiting gradually moldy ~~~~~~~~

Here also wish single men silver, female silver, in Singles Day Off "light" ~ ~ ~ ~ ~ ~ Cut to the point

First, brief

What do you think of calling WebService?

(1) Write a class that calls WebService (can be self-written or download a third-party class library)

(2) XML parsing of WebService returns (XML parsing from iOS is really annoying)

I am on the net Niang net, are to see some people, or only provide WebService class, simple explanation, for the return of the data XML, a word not to mention ~ ~ ~ with their written class to, really smoke AH ~ ~ ~ ~ ~ ~ ~ ~, I find some answers online, I feel very strange, Daniel often write a dubious words, to write to write clearly, otherwise simply do not write ~ ~ ~ Let people hope and disappointment ~ ~ I do not think that there are more bull B ... Instead, I prefer to simplify complicated events.

I personally encountered several problems when calling WebService:

A.webservice namespace issues?

WebService the default namespace is:http://tempuri.org/

I just started to use well, and later reported SOAPAction do not recognize http://tempuri.org/~~~~ Day spent a morning to find out this mistake, originally someone changed the default namespace of WebService ~ ~ ~ I went to your uncle's, changed the namespace, do not inform me, It's killing me to be blind ~

B.xml How to resolve the problem?

originally want to use the class of iOS to parse XML, on-line check, see others wrote a big, forehead a sweat, full face Black ~ ~ ~ ~ ~ ~, later I use is Google write Gdataxml this class library, also good ~ ~ ~, but for those XML has namespace of how to read, All kinds of jars to ask questions, so far no one has answered me correctly ~ ~ is no one in Celestial kingdom know? I was so disappointed that I was still like a god-clairvoyant ~ ~ ~ ~ ~ It has been settled, Amen ~ ~ ~

C. A 400 error occurred while calling asynchronously?

This problem made me, the mind garbled, the nerves are also the eggplant, you guess what is the reason ~ ~ ~

The message that soap intended to convey was this:

<a>XXX</a><b>XXXX</b>

I've reversed it and turned it into this:

<b>XXX</b><a>XXX</a>

After discovering the problem, I laughed like a fool ~ ~ ~

Ii. brief description of the class

(1) WebService (a class that is written using nsurlconnection, and a WebService call class that ASIHTTPRequest writes)

A. Synchronous invocation

B. Asynchronous invocation

C. Processing of returned data

The data returned by the SOAP call is often placed in the following: <webservice method name Result>xxx</webservice method name Result>, I have been directly extracted in the WebService call, ~ ~ ~ Extract the content is still an XML, the processing of this content, I write in the XML parsing class alone

(2) XML parsing class

1. Read the contents of the < Method name result>xxx</method name result>

2. Iterate through all the contents of the XML to return an array

Third, the use of configuration

(1) WebService call class with Nsurlconnection write, class name: WebServices.h

The following files are included:

Configuration of the A.appconfigure.h file:

The B.google Gdataxml is configured as follows:

Step1. Add Libxml2.dylib class Library First, do not tell me this is not, pull to Wall ~ ~ ~

Step2. Operation as shown

(2) with the help of ASIHTTPRequest write WebService call class, class named: ServiceHelper.h

As with (1) configuration, this is no longer repeated, asihttprequest to add a few more class libraries, as shown in

Iv. File Download

(1) All files of the WebService call class written by the Nsurlconnection class are downloaded
