Question

大家好解析一个xml文件并保存在一个nsmutabledictionary中，同时重新获取它给出的重复值。

 <CalculateCSResult>

        <Message>Hi This is the calculated info</Message>

        <Custodial>

          <Income>22</Income>

          <OverNights>12</OverNights>

          <ExemptionAmount>425</ExemptionAmount>

          <StandardDeduction>512</StandardDeduction>

          <FedTaxableIncome>8569</FedTaxableIncome>

          <FederalTax>245</FederalTax>

          <StateTax>451</StateTax>

          <FICA>451</FICA>

          <NetIncome>652</NetIncome>

          <NetIncomePct>412542</NetIncomePct>

        </Custodial>

        <NonCustodial>

          <Income>842</Income>

          <OverNights>652</OverNights>

          <ExemptionAmount>356</ExemptionAmount>

          <StandardDeduction>541</StandardDeduction>

          <FedTaxableIncome>658</FedTaxableIncome>

          <FederalTax>412</FederalTax>

          <StateTax>142</StateTax>

          <FICA>652</FICA>

          <NetIncome>696</NetIncome>

          <NetIncomePct>96896</NetIncomePct>

        </NonCustodial>

        <TaxYear>523</TaxYear>

        <ChilsSupportAmt>652</ChilsSupportAmt>

        <CutodialChildTaxCredit>652</CutodialChildTaxCredit>

        <Alerts>xmlxml</Alerts>

      </CalculateCSResult>


#import "ResultParser.h"

@implementation ResultParser

@synthesize calcResult; 
NSMutableDictionary *tempDict;

-(void)parse:(NSURL *)url {
    NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithContentsOfURL:url];
    tempDict = [[NSMutableDictionary alloc]init];
    [xmlParser setDelegate:self];
    if(![xmlParser parse])
        NSLog(@"Error Error Error!!!");
}

    } 

}

    if(!currentElementValue) 
        currentElementValue = [[NSMutableString alloc] initWithString:string];
    else
        [currentElementValue appendString:string];
}

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName 
  namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {

    if([elementName isEqualToString:@"CalculateCSResult"]) {
        return;
    }else if([elementName isEqualToString:@"Message"]) {
        [calcResult setObject:currentElementValue forKey:elementName];
    }else if([elementName isEqualToString:@"Income"] ||
        [elementName isEqualToString:@"OverNights"] || 
             [elementName isEqualToString:@"ExemptionAmount"] ||
             [elementName isEqualToString:@"StandardDeduction"] ||
             [elementName isEqualToString:@"FedTaxableIncome"] ||
             [elementName isEqualToString:@"FederalTax"] || 
             [elementName isEqualToString:@"StateTax"] || 
             [elementName isEqualToString:@"FICA"] || 
             [elementName isEqualToString:@"NetIncome"] ||
             [elementName isEqualToString:@"NetIncomePct"]) {
        [tempDict setObject:currentElementValue forKey:elementName];
    }else if([elementName isEqualToString:@"NonCustodial"] || [elementName isEqualToString:@"Custodial"]) {
        [calcResult setObject:tempDict forKey:elementName];
        [tempDict removeAllObjects];
    }else if([elementName isEqualToString:@"TaxYear"]) {
        [calcResult setObject:currentElementValue forKey:elementName];
    }else if([elementName isEqualToString:@"ChilsSupportAmt"]) {
        [calcResult setObject:currentElementValue forKey:elementName];
    }else if([elementName isEqualToString:@"CutodialChildTaxCredit"]) {
        [calcResult setObject:currentElementValue forKey:elementName];
    }else if([elementName isEqualToString:@"Alerts"]) {
        [calcResult setObject:currentElementValue forKey:elementName];
    }

    [currentElementValue release];
    currentElementValue = nil;      
}

- (void)dealloc {
    [tempDict release];
    [calcResult release];
    [super dealloc];
}

@end

并解析并将resRict中的calcResult字典保存在另一个类中并显示如下。

NSLog(@" message = %@",[resDict objectForKey:@"Message"]);
    NSMutableDictionary *custDict =(NSMutableDictionary *)[resDict objectForKey:@"Custodial"];
    NSLog(@" Income = %@",[custDict objectForKey:@"Income"]);
    NSLog(@" OverNights = %@",[custDict objectForKey:@"OverNights"]);
    NSLog(@" ExemptionAmount = %@",[custDict objectForKey:@"ExemptionAmount"]);
    NSLog(@" StandardDeduction = %@",[custDict objectForKey:@"StandardDeduction"]);
    NSLog(@" FedTaxableIncome = %@",[custDict objectForKey:@"FedTaxableIncome"]);
    NSLog(@" FederalTax = %@",[custDict objectForKey:@"FederalTax"]);
    NSLog(@" StateTax = %@",[custDict objectForKey:@"StateTax"]);
    NSLog(@" FICA = %@",[custDict objectForKey:@"FICA"]);
    NSLog(@" NetIncome = %@",[custDict objectForKey:@"NetIncome"]);
    NSLog(@" NetIncomePct = %@",[custDict objectForKey:@"NetIncomePct"]);
    NSMutableDictionary *ncustDict =(NSMutableDictionary *)[resDict objectForKey:@"NonCustodial"];
    NSLog(@" Income = %@",[ncustDict objectForKey:@"Income"]);
    NSLog(@" OverNights = %@",[ncustDict objectForKey:@"OverNights"]);
    NSLog(@" ExemptionAmount = %@",[ncustDict objectForKey:@"ExemptionAmount"]);
    NSLog(@" StandardDeduction = %@",[ncustDict objectForKey:@"StandardDeduction"]);
    NSLog(@" FedTaxableIncome = %@",[ncustDict objectForKey:@"FedTaxableIncome"]);
    NSLog(@" FederalTax = %@",[ncustDict objectForKey:@"FederalTax"]);
    NSLog(@" StateTax = %@",[ncustDict objectForKey:@"StateTax"]);
    NSLog(@" FICA = %@",[ncustDict objectForKey:@"FICA"]);
    NSLog(@" NetIncome = %@",[ncustDict objectForKey:@"NetIncome"]);
    NSLog(@" NetIncomePct = %@",[ncustDict objectForKey:@"NetIncomePct"]);
    NSLog(@" TaxYear = %@",[resDict objectForKey:@"TaxYear"]);
    NSLog(@" ChilsSupportAmt = %@",[resDict objectForKey:@"ChilsSupportAmt"]);
    NSLog(@" CutodialChildTaxCredit = %@",[resDict objectForKey:@"CutodialChildTaxCredit"]);
    NSLog(@" Alerts = %@",[resDict objectForKey:@"Alerts"]);

问题是它没有显示保管详细信息......对于保管和非保管，显示NonCustodilal数据......

请帮帮我

感谢

问题是NSDictionary中的对象是浅层复制的，也就是说在将tempDict添加到calcResult之后，它只包含一个指向tempDict的指针。但是对于字典中的键不是这样，它们被复制并且以后不能修改而不影响字典的完整性。

此外，我想指出您可以使用NSLog(@“resDict = %@“, resDict);和类似内容转储字典的全部内容。

NSMutableDictionary保存重复值
