UITextField *textField = [[UITextField alloc] init];
// configure text field
self.navigationItem.titleView = textField

Of course you could also use a property in your view controller instead of a local variable.

Please provide some sample code or a screenshot if you want a good answer. May I suggest you read this document for future questions.

This is clearly a case of you calling isEqualToString on a UITextField when this is a method that must be called on a NSString.

Try this 

-(void)viewDidAppear:(BOOL)animated{
    UITextField *txtField=[[UITextField alloc] initWithFrame:CGRectMake(0, 0, 200, 30)];
    [txtField setBorderStyle:UITextBorderStyleRoundedRect];
    txtField.text=@"Hello";
    [self.navigationController.navigationBar addSubview:txtField];
}

Will look like..

isEqualToString is method of string class not UITextField. Thatswhy you get this error. You are passing method to wrong object. Use textField.text instead of textField alone

You have to call it on the UITextField's text property:

UITextField *myTextField = [[UITextField alloc] initWithFrame:...];
myTextField.text = @"someString";
...
[myTextField.text isEqualToString:@"someString"]
