iphone - NSString stringWithContentsOfFile 持久编译器错误

Question

#import <Foundation/Foundation.h>

int main(int argc, const char * argv[])
{

@autoreleasepool {
    NSString *a;
    NSString *b;
    //NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Testimony" ofType:@"docx"];
    NSString *nameString = [NSString stringWithContentsOfFile:@"/Testimony.docx"
                                                     encoding:NSUTF8StringEncoding
                                                        errro:NULL];

    NSArray *names = [nameString componentsSeparatedByString:@"\n"];

    for(NSString *n in names){

        NSRange p = [n rangeOfString:@"Tobi" options:NSCaseInsensitiveSearch];
        NSRange r = [n rangeOfString:@"tobi" options:NSCaseInsensitiveSearch];


        if(p.location != NSNotFound){
            //NSLog(@"%@", n);
            a = n;
        }
        if(r.location != NSNotFound){
            //NSLog(@"%@", n);
            b = n;
        }

    }
    if([a caseInsensitiveCompare:b] == NSOrderedAscending){
        NSLog(@"a %@ comes before b %@", a, b);
    }

}
return 0;
}

编译器不断给我“选择器没有已知的类方法”错误。word文档与程序在同一个文件夹中。我不知道出了什么问题。您的帮助将不胜感激。谢谢

你有一个错字和拼写错误

错误

NSString *nameString = [NSString stringWithContentsOfFile:@"/Testimony.docx"
                                                     encoding:NSUTF8StringEncoding
                                                        error:NULL];
