小编典典

包含以下解决方案。可可CF具有CFXMLCreateStringByUnescapingEntities函数，但在iPhone上不可用。

@interface MREntitiesConverter : NSObject {

NSMutableString* resultString;

}

@property (nonatomic, retain) NSMutableString* resultString;

- (NSString*)convertEntitiesInString:(NSString*)s;

@end

@implementation MREntitiesConverter

@synthesize resultString;

- (id)init

{

if([super init]) {

resultString = [[NSMutableString alloc] init];

}

return self;

}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)s {

[self.resultString appendString:s];

}

- (NSString*)convertEntitiesInString:(NSString*)s {

if (!s) {

NSLog(@"ERROR : Parameter string is nil");

}

NSString* xmlStr = [NSString stringWithFormat:@"%@", s];

NSData *data = [xmlStr dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];

NSXMLParser* xmlParse = [[[NSXMLParser alloc] initWithData:data] autorelease];

[xmlParse setDelegate:self];

[xmlParse parse];

return [NSString stringWithFormat:@"%@",resultString];

}

- (void)dealloc {

[resultString release];

[super dealloc];

}

@end
