以下是代码：

NSString *title = @"facts";
NSString *type = @"txt";
NSString *separation = @"\n";
NSString *fileText = [NSString stringWithContentsOfFile:[[NSBundle mainBundle] pathForResource:title ofType:type] encoding:NSMacOSRomanStringEncoding error:nil];
NSMutableArray *facts = [[NSMutableArray alloc]initWithArray:[fileText componentsSeparatedByString:separation]];

NSLog(@"%@", [facts description]);

这是输出数组：

您指定的输入文件中有14行文本。文件开头有一个额外的换行符。这是额外计数之一。我只能猜测实际文件中有一个额外的新行。或许到最后？

我做了一些事情来完成这项工作。 我将@"/n"更改为@"\n" 我们将nil传递给error:而不是NULL 我记录了NSMutableArray的描述，为了便于阅读，我选择在第二步中进行初始化。 我还删除了文件顶部的额外换行符，并确保最后没有换行符。
