Switch 2 views with switch controller

Question

這是主視圖，我想切換兩個分離的視圖;用於ON狀態和OFF狀態。

代碼的外觀如何？

Answer 1

執行以下操作

- (void)viewDidLoad //of mainViewController { 
     //do viewController1 alloc init  // Gray Color 
     [self.view addSubview:viewController1.view]; 

     //do viewController2 alloc init  //Red Color 
     [self.view addSubview:viewController2.view]; 

     [viewController2.view setHidden:YES]; 
    } 

---

//assign this method to segmented controls' valueChanged event 
    - (IBAction)segmentControlClicked:(id)sender { 
     UISegmentedControl *segmentedControl = (UISegmentedControl *)sender; // if segmented control is not declared as an IBOutlet 
     if (segmentedControl.selectedSegmentIndex == 0) { 
      [viewController1.view setHidden:NO]; 
      [viewController2.view setHidden:YES]; 
     } 
     else if (segmentedControl.selectedSegmentIndex == 1) { 
      [viewController2.view setHidden:NO]; 
      [viewController1.view setHidden:YES]; 
     } 
    } 

確保 'Y' 起源viewController1和viewController2是分段的控制之下，這樣的分割控制不隱藏。

你可以在廈門國際銀行雙視角和主視圖，在視圖中添加這兩種觀點做負載，並設置爲隱藏的一個屬性，它不想顯示，然後設置隱藏屬性TRUE或關閉開關控制事件的FALSE。

請嘗試以下

- (IBAction)segmentControlClicked:(id)sender { 
    if (!viewController1) { 
     //do alloc init 
    } 
    if (!viewController2) { 
     //do alloc init 
    } 

    UISegmentedControl *segmentedControl = (UISegmentedControl *)sender; 
    if (segmentedControl.selectedSegmentIndex == 0) { 
     [viewController1.view setHidden:NO]; 
     [viewController2.view setHidden:YES]; 
    } 
    else if (segmentedControl.selectedSegmentIndex == 1) { 
     [viewController2.view setHidden:NO]; 
     [viewController1.view setHidden:YES]; 
    } 
}
