Question

Here is my code in appdelegate.m

NSURL *url = [[NSURL alloc] initWithString:kBioXML];
NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithContentsOfURL:url];

XMLParser *parser = [[XMLParser alloc]initXMLParser];
[xmlParser setDelegate:parser];     < - warning

XMLParser.h looks like

@class AppDelegate, Bio;

@interface XMLParser : NSObject {
NSMutableString *currentElementValue;

AppDelegate *appDelegate;
Bio *aBio;

NSString * bioText;
}
@property(nonatomic, retain) NSString *bioText;
- (XMLParser *) initXMLParser;
@end

And XMLParser.m

@implementation XMLParser

@synthesize bioText;

- (XMLParser *) initXMLParser{
[super init];
appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
bioText = @"";
return self;
}

The warning is “Sending XMLParser *” to parametr of incompatible type ‘id
what i should change to solve this warning?

thank you

Answer 1

Write this instead of your method..

-(id) initXMLParser
{
    self = [super init];
    if( self != nil )
    {
         appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
         bioText = @"";
    }
    return self;
}

Update

Implement NSXMLParserDelegate like this

In you .h file replace @interface XMLParser : NSObject with @interface XMLParser : NSObject <NSXMLParserDelegate> got it?
