Changing value of UITextField using an array doesn't work

I have an array located within the variable lstaInfo, as follows: 

[0] = fruits 
[1] = bee 
[2] = computer
[3] = cars

And I'm entering every part of the array in its respective text field, as follows:

-(void)setFields{

  field0.text = lstaInfo[0];
  field1.text = lstaInfo[1];
  field2.text = lstaInfo[2];
  field3.text = lstaInfo[3];
}

I'm calling setFields function in viewDidLoad, but every time I run the simulator, it crashes and returns me an error message called:

Thread 1: signal SIGABRT

The array is perfect and IBOutlets also, could someone help me?

Setting the array:

NSArray *lstaInfo = @[@"fruits",@"bee", @"computer", @"car"];

Then populating fields:

-(void)setFields{

  field0.text = lstaInfo[0];
  field1.text = lstaInfo[1];
  field2.text = lstaInfo[2];
  field3.text = lstaInfo[3];
}

Try to call setFields on viewWillAppear. The viewDidLoad method only is called once, when the view is loaded.

You are not using the "text" property of the UITextField.

It should be:

field0.text = lstaInfo[0];
