推荐答案

您有什么似乎罚款尽可能去。为了使比较不区分大小写的，你可以使用

What you have seems fine as far as it goes. To make the comparison case-insensitive, you can use

if ([txt.txt localizedCaseInsensitiveCompare:@"passwordToSkipLevel1"] == NSOrderedSame) {
    // ...
}

要更改的ViewController ...这是一个基于故事板的设计？如果是这样，你可以写

To change ViewController... is this a storyboard-based design? If so, you could write

if ([txt.txt localizedCaseInsensitiveCompare:@"passwordToSkipLevel1"] == NSOrderedSame) {
    [self performSegueWithIdentifier:@"SegueToLevel2VC" sender:self];
}

其中， SegueToLevel2CV 是你给了进入下一级别的SEGUE，当你构建了故事板中Interface Builder中输入的标识符。

where SegueToLevel2CV is the identifier you've given the segue that goes to the next level, typed in to Interface Builder when you constructed the storyboard.
