How to read a text file from my application's bundle and display it in a UITextView

I want to read a text file called "config.txt" from my application's bundle and display it in a UITextView. The code below is not working, can anyone help me?

IF i want to display it on a View then what i should do as well.

I have a IBOutlet to a UITextView, also please tell me how to change the text font and colour programmatically.

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"config" ofType:@"txt"];  
if (filePath) {  
    NSString *myText = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding];
    if (myText) {  
        textView.text= myText;    
    }
}


[super viewDidLoad];

The below code worked for me :

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"config" ofType:@"txt"]; 

if (filePath) {  
    NSError *error;
    NSString *myText = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:&error];

    if(!error) {
        if (myText) {  //config file contains text
            textView.font = [UIFont fontWithName:@“Times New Roman” size:16.0f];
            textView.textColor = [UIColor blackColor];
            textView.text= myText;    
        }
    }
    else {
        //Handle error while reading file
    }
}
else {
    //File path does not exists. Handle error
}

see whether your config.txt is normal or messy code I mean you may check your txt file in the X-code surroundings

Check to make sure textView is not nil and that you setup the IBOutlet connection in Interface Builder.

To set the font and color of the UITextView programmatically, use:

textView.font = [UIFont fontWithName:@"Helvetica" size:18.0f];

and

textView.textColor = [UIColor blueColor];

Is your file extension ".text" or ".txt"?

Also, why are you reading the file into an NSData object and then an NSString?
