我如何为borderWidth自定义所有UITextField外观？ [英] How may i customise all UITextField appearances for borderWidth?

问题描述

我正在尝试自定义borderWith的所有UITextField外观。

i am trying to customise all UITextField appearances for borderWith.

尝试类似的方法。
只有前2行有所作为。
其余行不起作用？

Trying something like this. Only first 2 lines are making a difference. Rest of the lines not working ?

[[UITextField appearance] setBackgroundColor:[UIColor greenColor]];
[[UITextField appearance] setTextColor:[UIColor blackColor]];
[UITextField appearance].layer.cornerRadius = 6.0f;
[UITextField appearance].layer.borderColor = [UIColor redColor].CGColor;
[UITextField appearance].layer.borderWidth = 3.f;

推荐答案

不幸的是，外观代理无法在做您想做的事情，您应该继承UITextField并在layoutSubviews方法（或init）中进行自定义

Unfortunately the appearance proxy doesn't work on layers to do what you want you should subclass UITextField and do your customisations in the layoutSubviews method (or in the init)
