我正在尝试读取CSV文件。我已经在我的应用程序中导入了该文件,因此该文件位于本地。当我执行下面的这部分代码时:
@autoreleasepool {
NSError *error;
NSString *alldata = [NSString stringWithContentsOfFile:@"config_menu_position.csv"
encoding:NSUTF16StringEncoding error:&error];
NSLog(@"alldata: %@", alldata);
NSLog( @"error: %@", error );
}
我有这个日志错误消息,我的变量总是为nul:
2013-04-21 17:05:37.571 PageViewController[1578:c07] alldata :(null)
2013-04-21 17:05:38.242 PageViewController[1578:c07] error: Error Domain=NSCocoaErrorDomain
Code=260 "The operation couldn’t be completed. (Cocoa error 260.)" UserInfo=0x7ebf100
{NSFilePath=config_menu_position.csv, NSUnderlyingError=0x7ebf060 "The operation couldn’t be
completed. No such file or directory"}
任何想法?

您缺少文件的完整路径,请尝试以下操作:
NSString* filePath = [[NSBundle mainBundle] pathForResource:@"config_menu_position" ofType:@"csv"];
NSString *alldata = [NSString stringWithContentsOfFile:filePath
encoding:NSUTF16StringEncoding
error:&error];

从pathForResource:ofType
尝试NSBundle
,例如
[[NSBundle mainBundle] pathForResource:@"config_menu_position" ofType:@"csv"]
然后使用A NSString
初始值设定项中返回的路径。
