Question

It will be probably a simple problem, but I have been staring on this for a while now and I can’t find it!

I have a SOAPRequest class like following:

@interface SoapRequest : NSObject

@property (retain, nonatomic) NSURL *endPoint;
@property (retain, nonatomic) NSString *soapAction;
@property (retain, nonatomic) NSString *userName;
@property (retain, nonatomic) NSString *passWord;
@property (retain, nonatomic) NSString *postData;
@property (retain, nonatomic) NSObject *handler;
@property SEL action;

+ (SoapRequest*) create: (NSObject*) target endPoint: (NSString*) endPoint action: (SEL) action soapAction: (NSString*) soapAction postData: (NSString*) postData;

- (id)sendSynchronous;
- (void) send;

@end

Implementation like following:

@synthesize endPoint = _endPoint, soapAction = _soapAction, userName = _userName, passWord = _passWord, postData = _postData, action = _action, handler = _handler;

+ (SoapRequest*) create: (NSObject*) target endPoint: (NSString*) endPoint action: (SEL) action soapAction: (NSString*) soapAction postData: (NSString*) postData
{
    SoapRequest *request = [[SoapRequest alloc] init];
    request.endPoint = [NSURL URLWithString:endPoint];
    request.soapAction = soapAction;
    request.handler = target;
    request.action = action;
    request.postData = postData;

    return [request autorelease];
}

And my send function:

- (void) send
{
    ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:self.endPoint];
    [request setDelegate:self];

    [request addRequestHeader:@"Content-Length" value: [NSString stringWithFormat:@"%d",[self.postData length]]];
    [request addRequestHeader:@"Content-Type" value:@"text/xml"];

    if(self.soapAction)
    {
        [request addRequestHeader:@"soapAction" value:self.soapAction];
    }

    [request appendPostData:[self.postData dataUsingEncoding:NSUTF8StringEncoding]];
    [request startAsynchronous];
}

I do have the default ASIHTTPRequest methods to listen for error or finish, my finish looks as following:

- (void)requestFinished:(ASIHTTPRequest *)request
{
    [self.handler performSelector:self.action];
}

The case is, it crashes when I want to make this class a delegate for the ASIHTTPRequest, [request setDelegate:self]. I figured it has something to do with the Autoreleasing in the first function. But I don’t have any idea how to fix it!

Edit:

This is how I init my SoapRequest:

- (SoapRequest*) DefinedEntities: (id) _target action: (SEL) _action
{

// some data inits

    SoapRequest *request = [SoapRequest create: _target endPoint:endPoint action:_action soapAction:soapAction postData:xmlString];
    [request send];

    return request;
}

And this i init as following:

Metadata *service = [[Metadata alloc] init];
[service DefinedEntities:self action:@selector(MetadataFinished:)];

Answer 1

Retaining was indeed a good option, I found some typo’s in my code and figured out what i did wrong already.

I had to do with the class in-between:

- (SoapRequest*) DefinedEntities: (id) _target action: (SEL) _action
{

// some data inits

    SoapRequest *request = [SoapRequest create: _target endPoint:endPoint action:_action soapAction:soapAction postData:xmlString];
    [request send];

    return request;
}
