ios导航条分段控制器 怎么分段导航

一、设置分段导航器

在ViewController。m里写

- (void)viewDidLoad {
    [super viewDidLoad];
    [self creatView];  
}

// 设置页面

- (void)creatView{
    UISegmentedControl *seg = [[UISegmentedControl alloc] initWithFrame:CGRectMake(5, 50, fDeviceWidth-10, 29)];
    [seg insertSegmentWithImage:@"按钮button" atIndex:0 animated:YES];
    [seg insertSegmentWithImage:@"标签label" atIndex:1 animated:YES];
    seg.tintColor = [UIColor redColor];
    seg.selectedSegmentIndex = 0;
    [seg addTarget:self action:@selector(seg:) forControlEvents:UIControlEventValueChanged];
    [self.view addSubview:seg];
// 初始化button 和 label 页面的位置
    _button = [[ButtonView alloc] initWithFrame:CGRectMake(0, 160, fDeviceWidth, fDeviceHeight)];
    [self.view addSubview:_button];
    _label = [[LabelView alloc] initWithFrame:CGRectMake(fDeviceWidth, 160, fDeviceWidth, fDeviceHeight)];
    [self.view addSubview:_label];  
}

// 页面之间的切换

- (void)seg:(UISegmentedControl *)Seg{
    if (Seg.selectedSegmentIndex == 0) {
        Seg.selectedSegmentIndex = 0;
        [UIView animateWithDuration:0.2 animations:^{
            _button.hidden = NO;
            _button.frame = CGRectMake(0, 80, fDeviceWidth, fDeviceHeight - 30) ;
            _label.frame = CGRectMake(fDeviceWidth, 50, fDeviceWidth, fDeviceHeight);
        }];
    }else{
        Seg.selectedSegmentIndex = 1;
        [UIView animateWithDuration:0.2 animations:^{
            _button.frame = CGRectMake(-fDeviceWidth, 50, fDeviceWidth, fDeviceHeight);
            _label.frame = CGRectMake(0, 80, fDeviceWidth, fDeviceHeight - 30) ;
            _button.hidden = YES; 
        }];  
    }  
}

二、设置导航的2个页面 button页面 和 label 页面

①、

_oneButton = [[UIButton alloc] initWithFrame:CGRectMake( 20, 20, 20, 20)];
    _oneButton.backgroundColor = [UIColor brownColor];
    [self addSubview:_oneButton];
 _twoButton = [[UIButton alloc] initWithFrame:CGRectMake(50, 50, 50, 50)];
    _twoButton.backgroundColor = [UIColor greenColor];
    [self addSubview:_twoButton];

 ②、

 

_oneLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 90, 200, 30)];
    _oneLabel.text = @"只要功夫深";
    _oneLabel.font = [UIFont systemFontOfSize:13];
    [self addSubview:_oneLabel];
 _twoLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 200, 200, 30)];
    _twoLabel.text = @"调查2222";
    _twoLabel.font = [UIFont systemFontOfSize:15];
    [self addSubview:_twoLabel];
