iphone - 如何在 iOS 中通过函数从同一个类调用 ViewDidLoad 方法

Question

我的第一个类是厨房课，从画廊课我将一些变量和对象传递给我的图像显示类，在我的图像显示类中有下一个图像按钮，当我按下该按钮时，我的图像中出现的所有图像显示类需要更改。

       MixViewController *mixVC = [[MixViewController alloc] init];
    mixVC.readOnlyMode = YES;
    mixVC.location = location;

    NSArray *tree = location.gallerySerialised;
    NSDictionary *galleryEntryTree = [tree objectAtIndex:tappedCoverIndex];
    NSArray *sliderStates = [galleryEntryTree objectForKey:@"state"];
    mixVC.infotext=[galleryEntryTree objectForKey:@"description"];
    mixVC.authortext=[galleryEntryTree objectForKey:@"author"];
    mixVC.tappedIndex=tappedCoverIndex;

    mixVC.initialSliderStates = [NSArray arrayWithObjects:
                                 [NSNumber numberWithInt:[[sliderStates objectAtIndex:0] intValue]],
                                 [NSNumber numberWithInt:[[sliderStates objectAtIndex:1] intValue]],
                                 [NSNumber numberWithInt:[[sliderStates objectAtIndex:2] intValue]],
                                 [NSNumber numberWithInt:[[sliderStates objectAtIndex:3] intValue]],
                                 [NSNumber numberWithInt:[[sliderStates objectAtIndex:4] intValue]],
                                 [NSNumber numberWithInt:[[sliderStates objectAtIndex:5] intValue]],
                                 nil];


    mixVC.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
    [self.parentViewController presentModalViewController:mixVC animated:YES];

这是我调用 mixviewcontroller 的代码。当我按下一个按钮时，我想更改 Sliderstates 的值并重新加载 View 以根据 slider 和图库索引显示新图像。

现在我在该类的混合图像类中，当用户单击 next 而不是我调用 nextGalleryview 函数时，我想更改图像，但它不会工作

我编写这段代码通过传递相同的值来调用 self view-did-load 但它不会改变任何东西。

感谢任何帮助谢谢

   -(void)nextGalleryView
      {
     NSLog(@"tap index is %i",tappedIndex);
        [ScrollView removeFromSuperview];
    self.readOnlyMode = YES;
    self.location = location;
    NSArray *tree = location.gallerySerialised;
    NSDictionary *galleryEntryTree = [tree objectAtIndex:tappedIndex];
    NSArray *sliderStates = [galleryEntryTree objectForKey:@"state"];
    self.infotext=[galleryEntryTree objectForKey:@"description"];
    self.authortext=[galleryEntryTree objectForKey:@"author"];
    self.tappedIndex=tappedIndex;

    self.initialSliderStates = [NSArray arrayWithObjects:
                                 [NSNumber numberWithInt:[[sliderStates objectAtIndex:0] intValue]],
                                 [NSNumber numberWithInt:[[sliderStates objectAtIndex:1] intValue]],
                                 [NSNumber numberWithInt:[[sliderStates objectAtIndex:2] intValue]],
                                 [NSNumber numberWithInt:[[sliderStates objectAtIndex:3] intValue]],
                                 [NSNumber numberWithInt:[[sliderStates objectAtIndex:4] intValue]],
                                 [NSNumber numberWithInt:[[sliderStates objectAtIndex:5] intValue]],
                                nil];
    [self viewDidLoad];
    }

您需要重新设计代码。

如果您希望从 viewDidLoad 和其他方法运行相同的代码，请将这些代码从 viewDidLoad 中拉出并将其放入一个方法中，然后从 viewDidLoad 和您的方法中调用此方法。

因为显式调用 viewDidLoad 并不好。
