Question

for (NSDictionary *status in statuses) 
    { 
     for (NSMutableString *name in [statuses objectForKey:@"response"]) 
     { 

      NSMutableString *name1=[[NSMutableString alloc] initWithFormat:@"%@",name]; 
      const char *utf8name=[name1 UTF8String]; 
      NSMutableString *name_str=[[NSMutableString alloc] initWithCString:utf8name encoding:4]; 

      [list_names addObject:[NSMutableString stringWithFormat:@"%@",name_str]]; 
      [name_str release]; 
     } 
NSLog(@"%@",list_names);

英文文本顯示正常，但俄羅斯not.How解決它？ 我鑫卡特在UTF8的問題，但我改變編碼爲UTF8並沒有變化。

Answer 1

當你這樣做：

NSLog(@"%@", list_names); 

它要求list_names的-description方法。對於NSArray，這會將數組打印出來，因爲它會出現在舊文本plist中。該%@格式說明通常用於當它不被使用的字符串調試。

的代碼轉換爲UTF-8，然後回到一個NSString。這次往返旅行毫無用處。

代碼使用[NSString stringWithFormat:@"%@", obj]。這相當於撥打[obj description]。

的代碼遍歷與未在循環體中使用的變量。

下面是一個簡單的建議：

for (NSDictionary *response in [status objectForKey:@"response"]) { 
    NSString *firstName = [response objectForKey:@"first_name"]; 
    NSString *lastName = [response objectForKey:@"last_name"]; 
    [list_names addObject:[NSString stringWithFormat:@"%@, %@", last_name, first_name]]; 
} 
NSLog(@"%@", list_names);
