I would simply like to read from a text file. I included the text file using File >> Add Files. I then added the file using Build Phases >> Copy File.

The code compiles. However, the warning I receive states "stringWithContentsOfFile is deprecated." I'm assuming it is not reading or finding the file properly. Any suggestions?

Here is my code:

#import <Foundation/Foundation.h>

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

    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
    
    NSString* fileName = @"Pie.txt";
    NSString *fileString = [NSString stringWithContentsOfFile: fileName];
        
    //NSArray *lines = [fileString componentsSeparatedByString:@"\n"];    
    
    //NSArray *recipeDictionaries = [[NSArray alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"Recipes" ofType:@"plist"]];


    [pool drain];
    return 0;
}

I am using XCode 4. I have not yet registered as an apple developer.

Sorry. That code was lame. I forgot to remove my comments. Here goes again:

#import <Foundation/Foundation.h>

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

NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

NSString* fileName = @"Pie.txt";
NSString *fileString = [NSString stringWithContentsOfFile: fileName];

[pool drain];
return 0;
}

If it works then you're ok for now. At some point that function may no longer be available, hence the warning.

Doing some poking around I was able to workout some code that worked for me. Being new to Object C myself I'm still learning how to play with directories.

Test file placed in home directory.

Programming is fun.
This is the second line.
This is the third line.

#import <Foundation/Foundation.h>

int main (int argc, const char * argv[])
{
    @autoreleasepool {
        NSString *fileName  = @"test.txt";
        NSString *homeDir   = NSHomeDirectory();
        NSString *fullPath  = [homeDir stringByAppendingPathComponent:fileName];

        NSString * inStr = [NSString stringWithContentsOfFile: fullPath
                                    encoding:NSASCIIStringEncoding 
                                    error:NULL];

        NSArray * strArray = [inStr componentsSeparatedByString:@"\n"];
        
        for (NSString * strLine in strArray) {
            NSLog(@"%@", strLine);
        } 
    }
    return 0;
}

What function are you referring to... stringWithContentsOfFile?

/r

Isn't that what you were talking about? You never said the code wasn't working so I assumed you were worried about the warning since you did talk about that.

Since I was not the original poster I can not say what he meant. I took his question as he was unable to read the file.

My question is is the function {stringWithContentsOfFile} going away in future release?

Here is a way without function {stringWithContentsOfFile}

#import <Foundation/Foundation.h>

int main (int argc, const char * argv[])
{
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

    NSString *fileName  = @"test.txt";
    NSString *homeDir   = NSHomeDirectory();
    NSString *fullPath  = [homeDir stringByAppendingPathComponent:fileName];
    NSArray * strArray = [NSArray arrayWithContentsOfFile:fullPath];;
            
    for (NSString * strLine in strArray) 
    {
        NSLog(@"%@", strLine);
    } 

    [pool drain];
    return 0;
}

Thanks. However, when I use my standard TXT file I receive:

2012-01-31 20:11:28.302 ReadToArray[6015:707] CFPropertyListCreateFromXMLData(): Old-style plist parser: missing semicolon in dictionary.
Program ended with exit code: 0

Now when I used a test plist it worked great.

2012-01-31 20:14:36.868 ReadToArray[6035:707] (
    HO,
    HI
)
Program ended with exit code: 0
