將項添加到字符串中不顯示字符

Question

for (NSString *item in items) { 
     NSString *ref = [item stringByMatching:myregex1 capture:2]; 
     NSString *value = [item stringByMatching:myregex1 capture:3]; 
     NSLog(@"%@ : %@", ref, value); 
     AllOrderItems = [AllOrderItems stringByAppendingFormat:(@"%@: %@ \r\n", ref, value)];  

    } 

AllOrderItems未顯示：或新行（\ r \ n）只是參考&值字符串？

請幫

感謝

在你的格式刪除括號：

AllOrderItems = [AllOrderItems stringByAppendingFormat:@"%@: %@ \r\n", ref, value];
