Xcode-9或iOS 11 -用\“not working”替换双引号

Question

因为我将双引号替换为转义字符，如下面代码中所述。相同的代码在iOS 10.x中运行良好，但在iOS 11中不起作用。

NSString *searchStr = [searchBar.text stringByReplacingOccurrencesOfString:@"\"" withString:@"\\\""];

NSString *searchInput = [[NSString alloc] initWithFormat:@"{\"@type\": \"com.xyz.rest.find.SearchQuery\",\"value\": \"%@\"}", searchStr];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:[searchInput dataUsingEncoding:NSUTF8StringEncoding]];

任何线索都将非常感谢！

提前感谢

这可能是因为iOS 11中引入了智能标点符号。请检查下面的链接。
