在代码中对button上的字进行设置,我们可以通过:
m_addButton.titleLabel.font = [UIFont systemFontOfSize: 7];
m_addButton.titleLabel.textColor = [UIColor blackColor];
m_addButton.titleLabel.textAlignment = UITextAlignmentRight;
但是改变上面的字的时候不能用
m_addButton.titleLabel.text = @"Add Stuff";
而是要通过
[m_addButton setTitle:@"1111" forState: UIControlStateNormal];
另外设置背景图以下两种方法也容易混淆:
[self setImage:[UIImageimageNamed:@"ic_home_page_unlike"]forState:UIControlStateNormal];
[self setBackgroundImage:[UIImageimageNamed:@"ic_home_page_unlike"] forState:UIControlStateNormal];
