ios xcode中怎么查看工程的路径

都要用到NSSearchPathForDirectoriesInDomains 这个函数找path 写入信息到iOS txt file: NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *fileName = [NSString stringWithFormat:@"%@/textfile.txt", documentsDirectory]; NSString *content = [[NSString alloc] initWithContentsOfFile:fileName usedEncoding:nil error:nil]; content=@"something"; [content writeToFile:fileName atomically:NO encoding:NSStringEncodingConversionAllowLossy error:nil]; 读取信息用同样的path: NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *fileName = [NSString stringWithFormat:@"%@/textfile.txt",documentsDirectory]; NSString *content = [[NSString alloc] initWithContentsOfFile:fileName usedEncoding:nil error:nil]; NSLog(@"%@",content); //我在自己的ipad上试过的，能行
