Question

我是IOS的新手并创建了一款应用。我正在使用CapsPageMenu iOS objective-c库。我在Tap上看到了这一点，例如：如果我有Tab1，Tab2，Tab3和Tab4，我当前在Tab1上，那么当我点击Tab4时，我看到Tab2的API也被调用了。这很可能是因为可以看到Tab2视图水平滚动一秒..但是我需要在加载时从每个选项卡上的Web服务获取数据。因此，这会导致不必要的网络呼叫。

如何确保仅在实际加载该选项卡时对选项卡执行Web服务调用，而不是滚动过去？

父ViewController CapsPageMenu

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.

    self.title = @"Point History";
    [self.navigationController.navigationBar setTitleTextAttributes:
     @{NSForegroundColorAttributeName:[ApplicationDesignClass sharedInstance].appLayoutDesign.appHeader._headerLabel._textColor}];

    ViewController *controller1 = [[AllViewController alloc]initWithNibName:@"AllViewController" bundle:nil];
    controller1.title = @"ALL";
    controller1.historyType = HistoryTypeAll;

    ViewController *controller2 = [[AllViewController alloc]initWithNibName:@"AllViewController" bundle:nil];
    controller2.title = @"ADDED";
    controller2.historyType = HistoryTypeAdded;

    ViewController *controller3 = [[AllViewController alloc]initWithNibName:@"AllViewController" bundle:nil];
    controller3.title = @"USED";
    controller3.historyType = HistoryTypeUsed;

    ViewController *controller4 = [[AllViewController alloc]initWithNibName:@"AllViewController" bundle:nil];
    controller4.title = @"UNUSED";
    controller4.historyType = HistoryTypeUnused;

    NSArray *controllerArray = @[controller1, controller2, controller3, controller4];
    NSDictionary *parameters = @{
                                 CAPSPageMenuOptionScrollMenuBackgroundColor: [UIColor blackColor],
                                 CAPSPageMenuOptionUnselectedMenuItemLabelColor: [UIColor whiteColor],
                                 CAPSPageMenuOptionSelectedMenuItemLabelColor: [UIColor lightgraycolor],
                                 CAPSPageMenuOptionViewBackgroundColor: [UIColor colorWithRed:20.0/255.0 green:20.0/255.0 blue:20.0/255.0 alpha:1.0],
                                 CAPSPageMenuOptionSelectionIndicatorColor: [UIColor whiteColor],
                                 CAPSPageMenuOptionBottomMenuHairlineColor: [UIColor colorWithRed:70.0/255.0 green:70.0/255.0 blue:70.0/255.0 alpha:1.0],
                                 CAPSPageMenuOptionMenuItemFont: [UIFont fontWithName:@"HelveticaNeue" size:13.0],
                                 CAPSPageMenuOptionMenuHeight: @(40.0),
                                 CAPSPageMenuOptionMenuItemWidth: @(70.0),
                                 CAPSPageMenuOptionCenterMenuItems: @(NO)
                                 };

    _pageMenu = [[CAPSPageMenu alloc] initWithViewControllers:controllerArray frame:CGRectMake(0.0, 0.0, self.view.frame.size.width, self.view.frame.size.height) options:parameters];
    [self.view addSubview:_pageMenu.view];
}

Child ViewController

注意： - 例如：如果我有AllTab，AddedTab，UsedTab和UnusedTab，我目前在AllTab上，那么当我点击UnusedTab时，我看到AddedTab数据显示但我想要UnusedTab数据显示

#import <UIKit/UIKit.h>
typedef NS_ENUM(NSInteger, HistoryType){
  HistoryTypeAll,
  HistoryTypeAdded,
  HistoryTypeUsed,
  HistoryTypeUnused
};
@interface ViewController : UIViewController
@property (nonatomic, assign) HistoryType historyType;
@end

CapsPageMenu API点击选项卡上单击
