iphone - 解析XML iPhone时清理URLS(主要用于空格)

我正在iphone应用程序中使用CXML解析XML，当我要搜索的位置（使用查询字符串）是一个单词时，效果很好。但是，当我添加一个空间（比如我正在寻找鞋店）时，它就会掉下来。我尝试用％20替换“”空间，但解析后似乎无法读取该URL。

我的代码：

- (IBAction)doSearch {

    NSString *trimmedWhat = [txtboxWhat.text stringByReplacingOccurrencesOfString:@" " withString:@"%20"];
    NSString *trimmedWhere = [txtboxWhere.text stringByReplacingOccurrencesOfString:@" " withString:@""];

    NSString *tempFullUrl = [NSString stringWithFormat:@"http://sampleurl.com/mobilesearch/place/%@/0/0/0/%@/0/0/0/0/0/0/0/0/search.aspx", trimmedWhat,  trimmedWhere];
    searchType = @"fullSearch";
    NSLog(@"Full String: %@",tempFullUrl);
    NSLog(@"Search Type: %@",searchType);

    PromotionViewController *passArray = [[PromotionViewController alloc] initWithNibName:@"PromotionViewController" bundle:nil];
    [passArray setCurrentCat: tempFullUrl];
    [passArray setCurrentType: searchType];
    [self.navigationController pushViewController:passArray animated:YES];
    [PromotionViewController release];
}

然后在我的PromotionViewController上：

 NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:
    [NSURL URLWithString: [NSString stringWithFormat:[NSString stringWithFormat:@"%@", currentCat]]]];
    [request setHTTPMethod: @"GET"];
    dataReply = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
    stringReplyServer = [[NSString alloc] initWithData:dataReply encoding:NSUTF8StringEncoding];

    if(currentType == @"categorySearch") {
...do parse
}

返回位置的网址时似乎就掉了

如何清理URL？

我已将以下内容添加到我的原始搜索过程中

 NSString *utfString = [tempFullUrl UTF8String];

    PromotionViewController *passArray = [[PromotionViewController alloc] initWithNibName:@"PromotionViewController" bundle:nil];
    [passArray setCurrentCat: utfString];
    [passArray setCurrentType: searchType];
    [self.navigationController pushViewController:passArray animated:YES];
    [PromotionViewController release];

但是它归结为以下内容：

2011-11-18 10:41:52.677 Del Search[2312:f203] Full String: http://web-xml.asdasdas.com/mobilesearch/place/(null)/0/0/0/<UITextField: 0x74709d0; frame = (15 7; 286 31); text = 'london'; clipsToBounds = YES; opaque = NO; autoresize = RM+BM; layer = <CALayer: 0x7470af0>>/0/0/0/0/0/0/0/0/search.aspx

最佳答案

- (IBAction)doSearch {
NSString * trimmedWhat =  [txtboxWhat.text stringByTrimmingCharactersInSet:        [NSCharacterSet whitespaceAndNewlineCharacterSet]];
NSString * trimmedWhere =  [txtboxWhat.text stringByTrimmingCharactersInSet:        [NSCharacterSet whitespaceAndNewlineCharacterSet]];
    NSString *tempFullUrl = [NSString stringWithFormat:@"http://sampleurl.com/mobilesearch/place/%@/0/0/0/%@/0/0/0/0/0/0/0/0/search.aspx", trimmedWhat,  trimmedWhere];
    searchType = @"fullSearch";
    NSLog(@"Full String: %@",tempFullUrl);
    NSLog(@"Search Type: %@",searchType);

    PromotionViewController *passArray = [[PromotionViewController alloc] initWithNibName:@"PromotionViewController" bundle:nil];
    [passArray setCurrentCat: tempFullUrl];
    [passArray setCurrentType: searchType];
    [self.navigationController pushViewController:passArray animated:YES];
    [PromotionViewController release];
}

NSString *utfString = [currentCat UTF8String];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:
    [NSURL URLWithString: utfString]];
    [request setHTTPMethod: @"GET"];
    dataReply = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
    stringReplyServer = [[NSString alloc] initWithData:dataReply encoding:NSUTF8StringEncoding];

    if(currentType == @"categorySearch") {
...do parse
}
