如何使用纯代码编写横屏的UIView?

1. 在UIView中,将该view使用到的坐标进行旋转,这样当该view addSubview时,会使用坐标方向来进行:

@implementation PoseDetailContentView

- (id)initWithFrame:(CGRect)frame 

{

    if (self = [super initWithFrame:frame]) 

{

            // Important here, rotate THIS UIView

            [self setCenter: CGPointMake(160.0f, 240.0f)];

            [self setTransform: CGAffineTransformMakeRotation(degreesToRadian(90))];

2. 

该view中的其他子视图使用原计划的坐标,添加到横屏中即可.

补充:

下面的代码,可以让UIView即旋转,又缩放.

        CGAffineTransform transform = CGAffineTransformMakeRotation(degreesToRadian(60));

        transform = CGAffineTransformScale(transform, 0.5, 0.5);

        

        [self setTransform: transform];    // this effects the SUBVIEWS rotate and scale
