我有自定义 UIButton，它是视图高度/宽度的 1/4。我想要做的是在按钮标题上方设置一个图像，它们都位于所述按钮的中心。
代码：
CGRect imageFrame= CGRectMake(0, 0, 80, 80);
UIEdgeInsets imageInset = UIEdgeInsetsMake(0, 0, 30, 0);
UIEdgeInsets titleInset = UIEdgeInsetsMake(80, 0, 0, 0);
btnSideSettings = [UIButton buttonWithType:UIButtonTypeCustom];
btnSideSettings.frame = settingsFrame;
[btnSideSettings setImage:[UIImage imageNamed:@"btnSideSettings"] forState:UIControlStateNormal];
btnSideSettings.imageView.frame = imageFrame;
btnSideSettings.imageEdgeInsets = imageInset;
btnSideSettings.titleEdgeInsets = titleInset;
btnSideSettings.titleLabel.textAlignment = NSTextAlignmentCenter;
[btnSideSettings setTitle:@"Settings" forState:UIControlStateNormal];
结果：
我尝试了上述代码的一些变体，主要是编辑插图。如果我注释掉添加图片，标题也会居中。感谢任何帮助。
