You can change the height of text field but you cannot use more than one line of data in text field instead you can use textview as given below:

UITextView *textView=[UITextView alloc]init];
textView.frame= CGRectMake(20,20, 455, 80);
textView.layer.cornerRadius=6;
textView.font = [UIFont systemFontOfSize:15.0];
textView.layer.borderWidth=1;
textView.layer.borderColor=[[UIColor grayColor] CGColor];
textView.textColor=[UIColor blackColor];
textView.editable=YES;
[self.view addSubView:textView];
