ios - IOS开发垂直按钮

Question

在我的项目中，我想做一个垂直按钮，文本也是垂直的，，，有人帮忙吗？！

完全一样的东西

Answer 1

Use this code to rotate the button

btn.transform = CGAffineTransformMakeRotation(-M_PI / 2);

And

btn.transform = CGAffineTransformMakeRotation(M_PI / 2);

Answer 2

You can instead rotate a button by using :

yrButton.transform = CGAffineTransformMakeRotation(90.0*M_PI/180.0);

This will give you 90 Degree rorate.

Answer 3

try like this i hope it'l helps you,

btn.transform= CGAffineTransformMakeRotation(DEGREES_TO_RADIANS(270));

and define

#define DEGREES_TO_RADIANS(x) (M_PI * x / 180.0) 

Answer 4

You can use CGAffineTransform for this purpose, it does the rotation according to your choice

Answer 5

您可以通过转换来实现这一点。

顺时针旋转：

button.transform = CGAffineTransformMakeRotation(90.0*M_PI/180.0);

和逆时针：

button.transform = CGAffineTransformMakeRotation(-90.0*M_PI/180.0);

第一个数字（90.0 或 -90.0）指定旋转按钮的角度（以度为单位）。
