我想要獲得有關每個WiFi網絡名稱及其噪音/強度的信息。任何機構都可以告訴我該怎麼做。

Answer 1

不知道我是否理解這個問題。試着讓它更清楚一點。

無論如何，這是我的理解。

NSString *path = [[NSBundle mainBundle] pathForResource:@"/Users/admin/Desktop/wi-fi" ofType:@"txt"]; 
NSArray *categories = [NSArray arrayWithContentsOfFile:path]; 
for (NSDictionary *category in categories) { 
    NSLog(@"%@", [category objectForKey:@"Interfaces"]); 
    NSLog(@"%@", [category objectForKey:@"Software Versions"]); 
} 

我還沒跑這個，但我認爲這應該工作，給它一個鏡頭。希望這是類似於你正在尋找的東西。如果不是，希望它朝着正確的方向發展，並且讓你更接近找到答案。快樂的編碼！

編輯：

拖動文本文件到您的項目，然後執行以下

NSString *path = [[NSBundle mainBundle] pathForResource:@"nsdictionarytextfile" ofType:@"txt"]; 
NSString *content = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:NULL]; 
NSArray *testArray = [content componentsSeparatedByString:@"\n"]; 
NSString *topDictionary = @""; 
NSMutableDictionary *dict = [NSMutableDictionary dictionary]; 
NSMutableDictionary *finalDict = [NSMutableDictionary dictionary]; 
for(NSString *s in testArray){ 
    NSArray *newArray = [s componentsSeparatedByString:@":"]; 
    if([newArray[1] isEqualToString:@""]){ 
     if([dict count] == 0){ 
      topDictionary = newArray[0]; 
     } 
     else{ 
      topDictionary = [topDictionary stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; 
      [finalDict setObject:[dict copy] forKey:[topDictionary copy]]; 
      [dict removeAllObjects]; 
     } 
    } else{ 
     NSString *object = [newArray[1] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; 
     NSString *key = [newArray[0] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; 
     [dict setObject:object forKey:key]; 
    } 
} 
topDictionary = [topDictionary stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; 
[finalDict setObject:dict forKey:topDictionary]; 
NSLog(@"finalDict: %@", finalDict); 

*請不說這還沒完！你必須找出更多的邏輯*

不真正知道你想要他們，但這應該讓你看看它應該如何工作。我沒有弄清楚添加頂級字典及其子級字典的完整邏輯，但是這應該使您處於正確的方向。我可能會首先刪除放在頂部詞典中的裁剪，並檢查字符串前面的空白/空格，然後用它來確定字典應該放在哪裏。 IE沒有空的空間意味着它是最高的一個，而更多的空白是它在字典中的「內在」。希望這可以幫助你開始。

您只有文本文件作爲輸入。這不是一個嵌套的字典。您應該將文件作爲文本讀取並首先進行解析。

該文件的格式看起來像YAML，但此時它不是有效的YAML。如果您有權訪問生成該文件的代碼，那麼確保它生成有效的YAML是有意義的。然後，您可以在Objective-C中使用one of available libraries解析YAML文件以嵌套NSDictionary s。否則，您應該爲輸入文本文件編寫自己的解析器。
