在 Objective-C 中打开 txt 文件并输出内容（但不适用于 OSX 或 iOS）

为了解决我的问题，我经常需要对 CSV 文件进行搜索和替换。我想通过用 Objective-C 编写我的需求来开始执行此操作，然后运行可执行文件来完成工作。

我目前有这段代码来打开一个文件并将其内容粘贴到一个字符串中。然后我在终端中编译它，然后运行它。

下面是整个程序的代码：

#import <Foundation/Foundation.h>

int main (int argc, const char *argv[])
{    
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
NSLog (@"Running....");


NSString* filePath = @"/Users/xxxxxx/Desktop/test_level2.txt";

NSString* fileContents = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];

NSLog(@"file contents --->%@", fileContents);


[pool drain];
return 0;

}

奇怪的是它只打印文件的部分内容。在 20 行中，它打印第一行和最后一行以及中间的一些随机部分。

知道如何解决这个问题吗？关于如何将文件的全部内容放入 NSString 中的任何建议？

Just to give context to my problem, I often have to run search and replace on CSV files. I would like to start doing this by coding my needs in Objective-C and then run the executable to get the job done.

I currently have this chunk of code to open a file and stick it's contents into a string. I then compile it in terminal and then run it.

Here is the code of the entire program:

#import <Foundation/Foundation.h>

int main (int argc, const char *argv[])
{    
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
NSLog (@"Running....");


NSString* filePath = @"/Users/xxxxxx/Desktop/test_level2.txt";

NSString* fileContents = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];

NSLog(@"file contents --->%@", fileContents);


[pool drain];
return 0;

}

The weird thing about this is that it prints only some of the contents of the file. Out of 20 lines, it prints the first and the last and some random parts from the middle.

Any idea of how I can solve this? Any suggests of how I can get the entire contents of the file into an NSString?
