我有另一个新手问题.
我写了一段代码,将NSString转换为NSMutableData,以模拟一个webService结果.
但事实证明,cString已被弃用.你可以帮我更换吗？
这是我的代码
- NSString *testXMLDataString =
- @"<?xml version=\"1.0\" encoding=\"UTF-8\"?>"
- etc....
- "</SOAP-ENV:Envelope>";
- //Replace webData Received from the web service with the test Data
- NSMutableData *testXMLData = [NSMutableData dataWithBytes:[testXMLDataString cString] length:[testXMLDataString length]];
- [webData setData:testXMLData];
解决方法
>从字符串获取原始字节.
>获取UTF8编码中这些字节的长度.
>使用dataWithBytes：length：方法创建NSData对象.
>获取UTF8编码中这些字节的长度.
>使用dataWithBytes：length：方法创建NSData对象.
- const char *rawBytes = [testXMLDataString UTF8String];
- const NSUInteger length = [testXMLDataString lengthOfBytesUsingEncoding:NSUTF8StringEncoding];
- NSAssert(length > 0,@"Couldn't convert to UTF-8");
- NSMutableData *testXMLData = [NSMutableData dataWithBytes:rawBytes length:length];
- [webData setData:testXMLData];
