两个viewController的view显示到另一个viewController

就是addChildViewController,没什么好解释的,代码粘过来方便下次偷懒

#import "SegmentHistoryViewController.h"
#import "HistoryViewController.h"
#import "PatientHistoryViewController.h"

@interface SegmentHistoryViewController ()
{
    HistoryViewController *historyVC;
    PatientHistoryViewController *patientHisVC;
    UIView *leftView, *rightView;
}
@end

@implementation SegmentHistoryViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    NSArray *segArr = @[@"接诊统计", @"接诊记录"];
    UISegmentedControl *segment = [[UISegmentedControl alloc]initWithItems:segArr];
    segment.frame = CGRectMake(10, 100, self.view.frame.size.width-2*87, 25);
    segment.selectedSegmentIndex = 0;
    segment.tintColor = [UIColor whiteColor];
    [segment addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
    self.navigationItem.titleView = segment;
    
    historyVC = [HistoryViewController new];
    patientHisVC = [PatientHistoryViewController new];
    [self addChildViewController:historyVC];
    [self addChildViewController:patientHisVC];
    //将viewController的view定制frame之后加入到self.view上。
    historyVC.view.frame = self.view.bounds;
    patientHisVC.view.frame = self.view.bounds;
    patientHisVC.view.hidden = YES;
    [self.view addSubview:historyVC.view];
    [self.view addSubview:patientHisVC.view];
    
}

- (void)segmentAction:(UISegmentedControl *)sender {
    if (sender.selectedSegmentIndex == 0) {
        //接诊统计
        historyVC.view.hidden = NO;
        patientHisVC.view.hidden = YES;
        [self.view resignFirst];
    } else {
        //就诊记录
        historyVC.view.hidden = YES;
        patientHisVC.view.hidden = NO;
    }
}
