iPhone:NSMutableURLRequest返回MS Word样式撇号的奇怪字符 [英] iphone: NSMutableURLRequest returns strange characters for MS Word style apostrophe

问题描述

我们正在使用XML/NSMutableURLRequest从我们的网站上提取内容，有时它会提取卷曲"样式的单引号和引号，而不是'.NSMutableURLRequest似乎讨厌这些并将它们变成奇怪的\ U00e2 \ U0080 \ U0099字符串.

We are pulling content off our website using XML/NSMutableURLRequest and sometimes it pulls through the "curly" style apostrophe and quotes, ’ rather than '. NSMutableURLRequest seems to hate these and turns them into the strange \U00e2\U0080\U0099 string.

我有什么办法可以防止这种情况发生?我正在使用GET方法，所以我应该以某种方式告诉它使用UTF-8吗?或者，我想念什么吗?

Is there something that I can to do prevent this? I am using the GET method, so should I be somehow telling it to use UTF-8? Or, am I missing something?

UIApplication* app = [UIApplication sharedApplication];
    app.networkActivityIndicatorVisible = YES;

    NSString *urlStr = [NSString stringWithFormat:@"%@",url];
    NSURL *serviceUrl = [NSURL URLWithString:urlStr];
    NSMutableURLRequest *serviceRequest = [NSMutableURLRequest requestWithURL:serviceUrl];
    [serviceRequest setHTTPMethod:@"GET"];

    NSURLResponse *serviceResponse;
    NSError *serviceError;

    app.networkActivityIndicatorVisible = NO;

    return [NSURLConnection sendSynchronousRequest:serviceRequest returningResponse:&serviceResponse error:&serviceError];

推荐答案

NSURLConnection 返回 NSData 响应.您可以使用该 NSData 响应并将其转换为字符串.然后将此字符串取回，将其返回为 NSData 对象，并在此过程中对其进行适当的UTF-8编码，然后将其提供给 NSXMLParser .

NSURLConnection returns an NSData response. You can take that NSData response and turn it into a string. Then take this string, turn it back into a NSData object, properly UTF-8 encoding it along the way, and feed it to NSXMLParser.

示例:(假设 response 是您请求中的 NSData 响应)

Example: (Assuming response is the NSData response from your request)

// long variable names for descriptive purposes
NSString* xmlDataAsAString = [[[NSString alloc] initWithData:response] autorelease];
NSData* toFeedToXMLParser = [xmDataAsAString dataUsingEncoding:NSUTF8StringEncoding];
NSXMLParser* parser = [[[NSXMLParser alloc] initWithData:toFeedToXMLParser] autorelease];
// now utilize parser...
