如何从较低级别的NSDictionary中提取NSDictionary

Question

我有一个NSDictionary，其中包含一个NSDictionary，该NSDictionary也包含NSDictionaries。现在，只有我拥有网站时，我就有了提取所需内容的代码。这是我的代码。

NSInteger selectedRow = [self.myTableView selectedRow];
NSString *currentName = [self.theFullArray objectAtIndex:selectedRow];

NSMutableArray *theOriginalArray = [self.theDictionary.allKeys mutableCopy];
if ([self.theDictionary.allKeys containsObject:@"#"]) {
    [theOriginalArray removeObject:@"#"];
}
NSMutableArray *sortedKeys = [[theOriginalArray sortedArrayUsingDescriptors:@[[NSSortDescriptor sortDescriptorWithKey:@"self" ascending:YES]]] mutableCopy];
if ([self.theDictionary.allKeys containsObject:@"#"]) {
    [sortedKeys addObject:@"#"];
}
NSArray *theFullDictObjects = sortedKeys;
NSUInteger theFullDictCount = [theFullDictObjects count];
NSDictionary *currentInfo = nil;

int firstI = 0;
while (firstI < theFullDictCount) {
    NSString *currentFullDictObject = [theFullDictObjects objectAtIndex:firstI];
    NSDictionary *theSubDict = [self.theDictionary objectForKey:currentFullDictObject];
    NSArray *theSubDictObjects = [theSubDict allKeys];
    NSUInteger theSubDictCount = [theSubDictObjects count];
    int secondI = 0;
    while (secondI < theSubDictCount) {
        NSString *currentDictObject = [theSubDictObjects objectAtIndex:secondI];
        if ([currentName isEqualToString:currentDictObject]) {
            NSDictionary *theDict = [theSubDict objectForKey:currentDictObject];
            currentInfo = theDict;
            break;
        }
        secondI++;
    }
    if (currentInfo) {
        break;
    }
    firstI++;
}
NSLog(@"currentInfo: %@", currentInfo);

现在这有效，但是当您的NSDictionaries列表很大时，它有点慢。是否有另一个代码可以更有效地执行此操作。

因此，假设我的值是“ www.adobe.com”，那么我如何获得

        <dict>
            <key>Name</key>
            <string>Adobe</string>
            <key>Website</key>
            <string>www.adobe.com</string>
            <key>Sub Category</key>
            <string>Technology</string>
            <key>Category</key>
            <string>Account</string>
            <key>PRLCountry</key>
            <string>Belgium</string>
        </dict>

如果您查看图片，可以看到字典的构建方式。

谢谢。
