經常用網路請求返回Json資料，

    其中字典或者陣列列印輸出中文，非看不懂的Unicode編碼

1.支援NSLog輸出中文

2.支援控制檯po輸出中文

實現方式==》：

1.新建NSDictionary分類 （Xcode8 ）

2.自動生成.h和.m檔案，在.m檔案如下實現（這樣就可以自動輸出中文了）：

// NSLog輸出

         NSMutableString *string = [NSMutableString string];

        // 開頭有個{
         [string appendString:@"{\n"];
    
        // 遍歷所有的鍵值對

         if (range.location != NSNotFound)
             [string deleteCharactersInRange:range];
