iphone - 制作一个垂直的 UIButton

Question

有没有办法让 UIButton 垂直显示，文本向下阅读，而不是横向显示？你能用IB或者编程的方式做到这一点吗？或者您需要使用 Photoshop 来制作自定义按钮吗？

干杯，山姆

Answer 1

// Define the transform
CGAffineTransform transform = CGAffineTransformMakeRotation(90 * (M_PI / 180));

// Initialize the UIView
UIView *myView    = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 320)];

// Do the transformation
// in this case, rotate the UIView 90 degrees
myView.transform = transform;
