关于af中url无法带中文的问题

AFURLRequestSerialization.m中

NSString*utf8Str = [[NSStringalloc]init];

NSString*urlUtf8 = [[NSStringalloc]init];

for(AFQueryStringPair*pairinAFQueryStringPairsFromDictionary(parameters)) {

utf8Str = [pair URLEncodedStringValue];

}

urlUtf8 = [URLStringstringByAppendingFormat:@"%@&",utf8Str];

NSLog(@"%@",urlUtf8);

NSMutableURLRequest*mutableRequest = [selfrequestWithMethod:methodURLString:urlUtf8parameters:nilerror:error];
