How to Read Data in Xcode

The XCode application provides iPhone developers with the necessary tools to create iPhone apps. XCode includes libraries for reading data files. You transfer and read data from text files stored on the phone. You can read other apps' data or import information from your users. The XCode NSData class facilitates data reads in your iPhone apps.

Instructions

1. Open your XCode development software and the iPhone project you want to edit. Double-click the iPhone file to import the data file.

2. Add a string variable to specify the file you want to import into the app. The following code specifies the mydata.txt file to the XCode compiler:

   NSString *file= [[NSBundle mainBundle] pathForResource:@"mydata" ofType:@"txt"];

3. Create the NSData class variable. You must initialize the NSData class before you can use its functions. The following code initializes the variable and points to the class to the mydata.txt file:

   NSData *data = [NSData file];

4. Display the file's data to the user, using a text view control in your app. The following code displays the data using the mytext control:

   mytext.text= data;
