我想从"
移除NSString
,但它无法解决问题。
该字符串来自XMLParser:
- (void)parser:(NSXMLParser *)parser
didEndElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI
qualifiedName:(NSString *)qName
{
if([elementName isEqualToString:@"li"]){
_isAnswer = NO;
}else if([elementName isEqualToString:@"span"]){
NSString *immutableString = [NSString stringWithString:currentElementValue];//currentElementValue is myMutableString
NSString* myString = [immutableString stringByReplacingOccurrencesOfString:@"\"" withString:@"00000"];
myString = [myString stringByReplacingOccurrencesOfString:@"״" withString:@"00000"];
myString = [myString stringByReplacingOccurrencesOfString:@"“" withString:@"00000"];
myString = [myString stringByReplacingOccurrencesOfString:@"”" withString:@"00000"];
NSLog(@“myString - ”,myString); } }
xml中的字符串包含"
日志:
myString - this is the " string
而不是:
myString - this is the 00000 string
答案 0 :(得分:0)
我已经测试了您的代码,这里的一切正常。代码中的某个地方存在问题,您没有共享...
NSString *str = @"LOL \"... ";
NSLog(@"%@",str);
str = [str stringByReplacingOccurrencesOfString:@"\"" withString:@"00000"];
NSLog(@"%@",str);
这是输出:
>> LOL "...
>> LOL 00000...
告诉我们您的字符串是如何初始化的
编辑:
1)首先确保它是"
字符,而不是“,”或“
2)尝试这样的事情,它与我的第一个答案结果相同。
NSString *str = @"LOL \"... ";
unichar const maskChar = 0x0022; // Code of " char
NSString *mask = [[NSString alloc] initWithCharacters:&maskChar length:1];
NSLog(@"%@",str);
str = [str stringByReplacingOccurrencesOfString:mask withString:@"00000"];
NSLog(@"%@",str);
如果第二个解决方案不起作用,则不是"
字符
