iphone - UITextField 垂直对齐

Question

UITextField有没有办法在中间垂直对齐文本，UIControlContentVerticalAlignmentCenter或者UIControlContentVerticalAlignmentBottom我必须使用其中一个？

Answer 1

您应该继承 UITextField，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);
}
