如何使UILabel和UITextField字体大小相对于屏幕大小 [英] How to make UILabel and UITextField font size to be relative to screen size

问题描述

我有一个具有文本字段和标签的视图控制器，并且为文本字段和标签设置了高度限制，因此我觉得字体大小与我认为的屏幕无关.

I have a view controller which has a text field and label and I have set height constraint for text field and label and so I feel font size is not relative to the screen I believe.

如何使该项目的字体大小相对于屏幕大小?

How can I make this items' font size to be relative to the screen size?

推荐答案

您可以在ViewController的viewDidLayoutSubviews方法或superView的layoutSubviews方法中手动更改UIlabel或UITextfield字体.像这样:

You can manually change UIlabel or UITextfield font in viewDidLayoutSubviews method of your ViewController or layoutSubviews method of your superView. Like this:

CGRect screenSize = [UIScreen mainScreen].bounds;
textField.font = [UIFont fontWithName:@"YourFont-Name"  
    size:screenSize.size.width/15.f];
