UITextField垂直对齐

Question

有没有办法在UITextField和UIControlContentVerticalAlignmentCenter之间的UIControlContentVerticalAlignmentBottom中间垂直对齐文字，还是我必须选择其中一个？

Answer 1

您应该为UITextField创建子类，并覆盖以下方法：

- (CGRect) textRectForBounds: (CGRect) bounds
{
  CGRect origValue = [super textRectForBounds: bounds];

  /* Just a sample offset */
  return CGRectOffset(origValue, 0.0f, 4.0f);
}

- (CGRect) editingRectForBounds: (CGRect) bounds
{
  CGRect origValue = [super textRectForBounds: bounds];

  /* Just a sample offset */      
  return CGRectOffset(origValue, 0.0f, 4.0f);
}
