我想,當鍵盤出現在iPhone上滾動我的文本框了起來,我使用下面的代碼,但我得到的錯誤:屬性「出身」對象類型未找到「的UITextField」
Property 'origin' not found on object type 'UITextField'
studentLoanTextBox.frame = CGRectMake(
studentLoanTextBox.origin.x,
studentLoanTextBox.origin.y - 100.0,
studentLoanTextBox.frame.size.width,
studentLoanTextBox.frame.size.height
);
