You're using a round rect button which is pretty ugly, and pretty hard to customise.
您正在使用一个圆形的矩形按钮，它非常难看，而且很难定制。
You can create a custom type button and use a background image, or create a custom type button and round the corners and set the background colour of the layer yourself.
您可以创建自定义类型按钮并使用背景图像，或创建自定义类型按钮并圆角并自己设置图层的背景颜色。
If you want to get really fancy there is a nice tutorial herewhich can give you any-sized gradient type buttons using layers, no image files required.
如果你想变得非常喜欢这里有一个很好的教程，它可以为你提供使用图层的任何大小的渐变类型按钮，不需要图像文件。

I discovered this almost by accident:
我几乎是偶然发现的：
self.loginButton.tintColor = [UIColor redColor];
Definitely works and has been available since iOS 2.0.
绝对有效并且自 iOS 2.0 以来一直可用。
