I am following your code on page 185 and received an error for the last two lines of code for setBorderStyle and setPlaceholder. Xcode generated this message, "! Receiver type ‘UITextView’ for instance message does not declare a method with selector 'setBorderStyle’
I am not sure what this means.
// Create and configure the text field where new tasks will be entered
taskField = [[UITextField alloc] initWithFrame:fieldFrame];
[taskField setPlaceholder:@“Type a task, tap Insert”];
