ios - CHCSV 解析器错误 : No known class method for selector 'arrayWithContentsOfCSVFile:encoding:error:'

Question

当尝试像这样使用 CHCSV 解析器时:

#import "CHCSVParser.h"
....

- (IBAction)hi:(id)sender {
    NSString *path = [[NSBundle mainBundle] pathForResource:@"nood" ofType:@"csv"];

    NSError *error = nil;
    NSArray *rows = [NSArray arrayWithContentsOfCSVFile:path encoding:NSUTF8StringEncoding error:&error];
    if (rows == nil) {
        //something went wrong; log the error and exit
        NSLog(@"error parsing file: %@", error);
        return;
    }

}

我得到错误:

No known class method for selector arrayWithContentsOfCSVFile:encoding:error:

我已经包含了 CHCSV header ，但此错误仍然发生。这个问题与this完全一样一个，但从未得到答复，因此请不要将其标记为重复。

Answer 1

The header from github貌似没有这种方法。您的选择似乎是:

+ (instancetype)arrayWithContentsOfCSVFile:(NSString *)csvFilePath;
+ (instancetype)arrayWithContentsOfCSVFile:(NSString *)csvFilePath options:(CHCSVParserOptions)options;

请注意，两者都没有 encoding: 参数。
