在字典中訪問字典中的字符串

Question

如何訪問plist文件中的字典中的字典中的字符串？ 我試過，但它不工作：

NSString *myfile = [[NSBundle mainBundle] pathForResource: arrayname ofType:@"plist"]; 
WordsDic = [[NSDictionary alloc] initWithContentsOfFile:myfile]; 

words = [WordsDic allKeys]; 

insidedic = [[NSDictionary alloc] initWithDictionary:[[words objectAtIndex:0] ]];; 
level2 = [insidedic allKeys]; 

然後我試過，但我得到一個錯誤

for (NSString *parent in words) { 

     insidedic = [WordsDic objectForKey:parent]; 
     level2 = [insidedic allKeys]; 

     NSLog(@"%@", level2); 
    } 

Answer 1

你可以嘗試這樣的：

for (NSString *key in [wordsDic allKeys]) { 
    NSDictionary *secondLevel = [wordsDic objectForKey:key]; 
    for (NSString *secondLevelKey in [secondLevel allKeys]) { 
     NSLog(@"%@",[secondLevel objectForKey:secondLevelKey]); 
    } 
} 

在您的代碼，「level2」是一個數組，而不是一個字符串，所以會與該NSLog語句崩潰。
