思路出自这篇博主的文章。

直接上代码

-(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
NSLog(@"你旋转了");
if (toInterfaceOrientation ==UIInterfaceOrientationLandscapeLeft ) {
[self addSegmentControl:UIInterfaceOrientationLandscapeLeft];
[self.segementControl_base addTarget:self action:@selector(clickOnSegment:) forControlEvents:UIControlEventValueChanged];
[self initData];
[self initLrc]; }
else if(toInterfaceOrientation == UIInterfaceOrientationLandscapeRight)
{
[self addSegmentControl:UIInterfaceOrientationLandscapeRight];
[self.segementControl_base addTarget:self action:@selector(clickOnSegment:) forControlEvents:UIControlEventValueChanged];
[self initData];
[self initLrc]; }
else
{
[self addSegmentControl:UIInterfaceOrientationPortrait];
[self.segementControl_base addTarget:self action:@selector(clickOnSegment:) forControlEvents:UIControlEventValueChanged];
[self initData];
[self initLrc]; }
}

通过给对应的segment传入当前的旋转状态来设置segment在旋转到不同的方向时加载的数据

-(void)addSegmentControl:(UIInterfaceOrientation)toInterfaceOrientation
{
[self.segementControl_base removeFromSuperview];
NSArray *segmentArray = [NSArray arrayWithObjects:@"基本课文",@"应用课文" ,@"单词",nil];
UISegmentedControl * segmentControl = [[UISegmentedControl alloc]initWithItems:segmentArray];
self.segementControl_base = segmentControl;
#warning 判断旋转方式
if(UIInterfaceOrientationLandscapeLeft == toInterfaceOrientation){
segmentControl.frame = CGRectMake(, self.navigationController.navigationBar.frame.size.height, self.view.frame.size.width, self.view.frame.size.height*0.1);
}else if(toInterfaceOrientation == UIInterfaceOrientationPortrait){
segmentControl.frame = CGRectMake(, , self.view.frame.size.width, self.view.frame.size.height*0.07);
}
else if (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight)
{
segmentControl.frame = CGRectMake(, self.navigationController.navigationBar.frame.size.height, self.view.frame.size.width, self.view.frame.size.height*0.1);
}
segmentControl.selectedSegmentIndex = tags;
// [segmentControl addTarget:self action:@selector(onSegmentedControlChanged:) forControlEvents:UIControlEventValueChanged];
[self.view addSubview:segmentControl];
}
