Question

我从一些linux盒子里获得了一些数据，并希望将它放入NSDictionary中以便以后处理。

你如何将这个NSString变成NSDictionary，如下所示？

data (
eth0 (Errors => 0, Bytes => 32, Packtes => 0, Index => 2,...)
eth1 (Errors => 0, Bytes => 32, Packtes => 0, Index => 2,...)
lo (Errors => 0, Bytes => 32, Packtes => 0, Index => 2,...)
...)

每个值都应该是可访问的，如：

NSString eth0_errors = [[data objectForKey:@"eth0"] objectForKey:@"Errors"];

数据字符串如下所示：

NSString *dummydata = [NSString stringWithFormat:@"+ 1\n"
                       "eth0 Errors 0\n"
                       "eth0 Bytes 34\n"
                       "eth0 Packets 0\n"
                       "eth0 Index 2\n"
                       "eth0 Type ETHER\n"

假设您的数据始终符合您指定的格式，您可以使用以下内容：

NSArray *components = [dummydata componentsSeparatedByString:@"\n"];
NSMutableDictionary *dictionary = [NSMutableDictionary new];

for(NSString *component in components) {
    NSArray *subcomponents = [component componentsSeparatedByString:@" "];

    if(subcomponents.count >= 3) {
        NSMutableDictionary *subdictionary = [dictionary objectForKey:[subcomponents objectAtIndex:0]];

        if(subdictionary == nil) {
            subdictionary = [NSMutableDictionary new];
            [dictionary setObject:subdictionary forKey:[subcomponents objectAtIndex:0]];
        }

        if(subcomponents.count > 3) {
            [subdictionary setObject:[subcomponents subarrayWithRange:NSMakeRange(2, subcomponents.count - 2)] forKey:[subcomponents objectAtIndex:1]];
        } else {
            [subdictionary setObject:[subcomponents objectAtIndex:2] forKey:[subcomponents objectAtIndex:1]];
        }
    }
}

请注意，数值将表示为NSStrings。如果您希望它们是NSNumbers，则需要在循环中执行其他检查和转换。
