Question

我不敢确定我做错做什么。我想到的是,国家宇宙航行局的名称和地段在不同的档案中申报。

#import <Foundation/Foundation.h>

@interface xmlToUrl : NSObject {    

    NSString *base_url;
    NSMutableArray *field;
    NSMutableArray *name;
}
@property(nonatomic,retain)NSString *base_url;
@property(nonatomic, retain)NSMutableArray *field;
@property(nonatomic, retain)NSMutableArray *name;

@end

以及

#import "xmlToUrl.h"

@implementation xmlToUrl
@synthesize base_url;
@synthesize field;
@synthesize name;

-(id) init
{
    self = [super init];
    if (self) {
        field = [[NSMutableArray alloc] init];
        name = [[NSMutableArray alloc] init];
    }
    return self;
}

-(void)dealloc
{
    [base_url release];
    [field release];
    [name release];
    [super dealloc];
}

@end

国家安全局观察仪表层填充:

//nodeContent is just a NSMutableString being added to the *name 以及 *field NSMutableArrays

if([ending isEqualToString:@"name"]){
        if(![nodeContent isEqualToString:@""])
        {[xmlToUrlObject.name addObject:nodeContent];}
    }
    else if([ending isEqualToString:@"field"]){
        if(![nodeContent isEqualToString:@""])
        {[xmlToUrlObject.field addObject:nodeContent];}

Error = 预期. before . token. (关于以下法典第一行)

What I want for output: *url string contains base_url, urlPart2, 以及 urlPart3 all joined in order.

注

Base_url = @"www

url Part2 = @“mywebsite”

urlPart3 = @ .com

url = @“www.mywebsite.com”

//xmlToUrl is an instance of its own class (.m file)  It contains the *name 以及 *field NSMutableArray
//xmlToUrl.h is inherited in this file

NSMutableString *urlPart2 = [xmlToUrl.name objectAtInd注 0];
    [xmlToUrl.name removeObjectAtInd注0];
    NSMutableString *url = [xmlToUrl.base_url stringByAppendingString:urlPart2];

    if([xmlToUrl.field count] != 0)
    {NSMutableString *urlPart3 = [xmlToUrl.field objectAtInd注 0];
    [xmlToUrl.field removeObjectAtInd注0}
    url = [url stringByAppendingString:urlPart3];

     [urlPart2 release];
     [urlPart3 release];

Answer 1

你们试图获得某类财产,而不是:

@interface xmlToUrl : NSObject {

以及

NSMutableString *urlPart2 = [xmlToUrl.name objectAtIndex: 0];

只有在Xml的情况下,你才能获得财产。与你一样,敦促:

{[xmlToUrlObject.name addObject:nodeContent];}

Here, xmlToUrlObject is an instance, 以及 not the class.
