ios - 在 UIView 中的 UISegmentedControl 中切换 View

Question

我在切换 UISegmentedControl View 时遇到了问题。我导入了 HMSegmentedControl 框架来使用多个 View (7 个 View )。我想在点击“新匹配”时切换 View ，它应该显示匹配 View ，而在点击“每日推荐”时，它应该显示匹配 View 等等。下面是我的代码。我已经尝试了很多通过 segmentedControlChangedValue 切换 View ，但它对我不起作用。有什么要做的还是我做错了吗？

  @interface MatchesViewController ()
  @property (nonatomic, strong) UIScrollView *scrollView;
  @property (strong, nonatomic) IBOutlet UIScrollView *scrollVw;
  @property (strong, nonatomic) IBOutlet UIView *matchesView;
  @property (strong, nonatomic) IBOutlet UIView *dailyRecommendationsView;
  @property (strong, nonatomic) IBOutlet UIView *preferedMatchesView;
  @property (strong, nonatomic) IBOutlet UIView *broaderMatchesView;
  @property (strong, nonatomic) IBOutlet UIView *twowayMatcheVsiew;
  @property (strong, nonatomic) IBOutlet UIView *reverseMatchesView;
  @property (strong, nonatomic) IBOutlet UIView *decideLaterView;
  - (IBAction)btnMenuClicked:(id)sender;
  @end

  @implementation MatchesViewController

  - (void)viewDidLoad {
  [super viewDidLoad];
  self.title = @"Matches";
  self.navigationController.navigationBar.barTintColor = [UIColor colorWithRed:16/255.0 green:97/255.0 blue:61/255.0 alpha:1.0];

  [self.navigationController.navigationBar
  setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}];


  [self.scrollVw addSubview:self.matchesView];
  [self.scrollVw setContentSize:CGSizeMake(self.view.frame.size.width, self.matchesView.frame.size.height)];

  [self.scrollVw addSubview:self.dailyRecommendationsView];

  segmentedControl1.selectionStyle = HMSegmentedControlSelectionStyleFullWidthStripe;
  segmentedControl1.selectionIndicatorLocation = HMSegmentedControlSelectionIndicatorLocationDown;

  //segmentedControl1.selectionStyle = HMSegmentedControlSelectionStyleBox;
  //segmentedControl1.selectedSegmentIndex = HMSegmentedControlNoSegment;


  segmentedControl1.selectionIndicatorColor = [UIColor whiteColor];
  segmentedControl1.selectionIndicatorHeight = 2.0f;
  segmentedControl1.verticalDividerEnabled = YES;
  segmentedControl1.verticalDividerColor = [UIColor whiteColor];
  segmentedControl1.verticalDividerWidth = 1.0f;
  [segmentedControl1 setTitleFormatter:^NSAttributedString *(HMSegmentedControl *segmentedControl, NSString *title, NSUInteger index, BOOL selected) {
  NSAttributedString *attString = [[NSAttributedString alloc] initWithString:title attributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}];
  return attString;
  }];

  [segmentedControl1 addTarget:self action:@selector(segmentedControlChangedValue:) forControlEvents:UIControlEventValueChanged];
  [self.view addSubview:segmentedControl1];

  [self.navigationController.navigationBar
  setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}];

  }

  - (void)uisegmentedControlChangedValue:(UISegmentedControl *)segmentedControl {
  NSLog(@"Selected index %ld", (long)segmentedControl.selectedSegmentIndex);

  }

Answer 1

您的方法 segmentedControlChangedValue 是否被调用？

尝试在其上添加断点并跟踪 segment.selectedSegmentIndex 值。我认为问题出在这里。

由于 HMSegmentedControl 不是 UISegmentedControl 的子类而是 UIControl 的子类，方法应该是:

  - (void)segmentedControlChangedValue:(HMSegmentedControl *)segment

代替:

  - (void)segmentedControlChangedValue:(UISegmentedControl *)segment

希望这对您有所帮助。
