Cross dissolve transition required without using segue
提问by RGriffiths
I want to use the Cross Dissolve transition but not by using a segue. I use the code below to present the new view when a button is pressed but the transition is Cover Vertical. Is there any way of changing this?
我想使用 Cross Dissolve 过渡，但不想使用 segue。我使用下面的代码在按下按钮时显示新视图，但过渡是 Cover Vertical。有什么办法可以改变这种情况吗？
ObViewControllerMonitorMenu *monitorMenuViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"observationSummary"];
monitorMenuViewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentViewController:monitorMenuViewController animated:YES completion:nil];
The code above now works with the additional line to set the transition type.
上面的代码现在使用附加行来设置转换类型。
回答by Valent Richie
Please take a look at the documentation to see the list of transition style while presenting a view controller modally, especially at the section Presenting View Controllers:
请查看文档以查看以模态方式呈现视图控制器时的过渡样式列表，尤其是在以下部分Presenting View Controllers：
https://developer.apple.com/reference/uikit/uiviewcontroller?language=objc
https://developer.apple.com/reference/uikit/uiviewcontroller?language=objc
（快速回答）
And then you can set the modalTransitionStyleproperty of the view controller to the desired value, in which what you want is UIModalTransitionStyleCrossDissolve.
然后你可以将视图控制器的modalTransitionStyle属性设置为所需的值，其中你想要的是UIModalTransitionStyleCrossDissolve.
