I have pageView where in the bottom of each page there is a scrollView.
I want that the pageView doesn't turn when the scrollView is scrolling.
My problem is:
when I scroll (in the scrollView) the pages turn with him!
This may not a good practice but it can solve your problem: in Xcode go to your project/ cocos2d_libs.xcodeproject/ extensions/ GUI/ CCScrollView
In CCScrollView.h add:
void mySetSwallowTouch(bool enabled);
In CCScrollView.cpp add:
void ScrollView::mySetSwallowTouch(bool enabled) {
_touchListener->setSwallowTouches(enabled);}
Now call mySetSwallowTouch(true) at your scrollview
scrollview->mySetSwallowTouch(true);
You can also use this with your table view inside a pageView
Since cocos2d-x v3.3 there is already a method void mySetSwallowTouch(bool enabled) available for ListView.
You can simply use it:
ListView* listView = ListView::create();
listView->setSwallowTouches(true);
BTW, I believe swallow touches is currently set to true for ListView by default.

I know that on the view you can add the following modifiers to modify the navigation bar to create a custom back button.
SomeView{ ... }
.navigationBarBackButtonHidden(true)
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
Button {
mode.wrappedValue.dismiss()
} label: {
Image(systemName: "chevron.backward")
}
}
However, I do not want to go through my entire app to every secondary view and add these modifiers. I've considered creating a reusable header component, but at the moment, I'm just wondering if there was a way to override the system default for the back button to impact the entire app.
Unfortunately In SwiftUI there is not. You could however, override UINavigationController but it is not recommended as APIs can change.
Look at List for example, we used to set the UITableView appearance background color to .clear to customize List's background, but in iOS 16 this solution works no more.
Extended View and create a func where you put your code in it, then use that function wherever you need!
I have an app that loads a tabbar with a view as initial screen, RecipeList(). Inside of RecipeList I call another view to show a recipe full screen. In RecipeList file I have code to show or hide the status bar checking if the recipe detail fullscreen view is loaded or not. It works perfectly if I preview it in xcode, BUT when I preview the code below, which is my Home() view file, and what I want to load as initial screen due to tabbar need, THEN the code inside of RecipeList to show or hide statusbar doesnt work anymore, and status bar is always on.
If i try to hide the statusbar in the code below, it works, but then is always off, something i dont want. Only wanna hide it for the fullscreen view.
I actually used this Introspect package from Github to hide the tabbar when the child view is loaded full screen, and i made it work!
SwiftUI hide TabBar in subview
https://github.com/siteline/SwiftUI-Introspect
Actually, I wonder if anyone has used Introspect to hide the statusbar like the tabbar. I tried to use it, but I am a rockie, I only know a bit of SwiftUI, no Swift, no view controller experience, nothing.
But I have a totally functional app with only this issue, and I am super frustrated not to have the skills to know why the tabbar view is forcing a persistent status bar.
Any help, please?
var body: some View {
ZStack {
Color("background2")
.edgesIgnoringSafeArea(.all)
TabView {
RecipeList().tabItem {
Image(systemName: "book.fill")
.font(.system(size: 24, weight: .bold))
Text("Galería")
}
PostList(section: sectionData[0]).tabItem {
Image(systemName: "list.bullet")
.font(.system(size: 22, weight: .bold))
Text("Listado")
}
}
.accentColor(Color("accent"))
.introspectTabBarController { tabBarController in
// customize here the UITabBarViewController if you like
self.viewModel.tabBarController = tabBarController
}
}
}
I can suggest you using the #EnvironmentObject wrapper which basically allows you to use an object as global state. You can find fair amount of tutorials explaining how to do that and inject it in your initial view so that this object is accessible in the whole view hierarchy.
Once you have that global state set up, you can hide your status bar conditionally like this:
MyOutterWrapper {
Text("Some text")
}
.statusBar(hidden: myGlobalState.statusBarHidden)
If you are using NavigationView note that hiding the status bar works best if you set it up there (also assuming navigation view is your first view that appears).
Now all you got to do is inside your view set the variable to true when entering full screen and set it back to false when exiting. Hope that helps!
EDIT: Forgot to mention that hiding status bar as of June 26, 2020 only works if it's set on the initial view. You cannot change it later and that's the reason we set up this variable in order to go back and change the value dynamically.
I want to flash the scrollbars of a ListView in Axway / Appcelerator Titanium. So I cast a Titanium ListView to a iOS UIScrollView and then try to call the flashScrollIndicators method on it, but I get an exception. Does anyone now how to accomplish this? See my code below:
-- View
<Alloy>
<Window onOpen="onWindowOpen">
<ListView id="listView">
etc...
-- Controller
// After displaying the ListView I call:
var UIScrollView = require('UIKit/UIScrollView');
var listView = UIScrollView.cast($.listView);
listView.flashScrollIndicators();
The $.listView object is natively a subclass of UIView, not a UIScrollView. It contains a UITableView as a child view. You could access the tableview like this:
var UIView = require('UIKit/UIView');
var listView = UIView.cast($.listView);//you cast it to be able to access it's native properties
listView.tableView.flashScrollIndicators();
Haven't tested it but I guess it should work.
When in doubt about the type of a Titanium UI element, just go and check the source code by opening the project compiled in the build/iphone directory. Open it with XCode and search for the header file.
newBie here. I have added an UItableViewController into storyBoard. I use this as a setting page.
HomeVC ----> Setting VC
In code : I use the below code to bring the tableView below the battery Bar:
self.tableView.contentInset = UIEdgeInsets(top: 20,left: 0,bottom: 0,right: 0)
Problem:
How to move the TableView down below the battery bar so that I can add a button above the table in StoryBoard
Please help.
For this you should use a normal view controller and drag a table on the view controller this way you can make the table size whatever you like. This will also allow you to place buttons wherever you like.
Don't forget to assign the TableViewDataSource and TableViewDelegate to your view controller.
Good luck!
After doing some search on UiTableViewController, to use it as setting page I have to set static cell to it. This UiTableViewController will occupy the entire view.
To set the tableView below the battery icon,
use:self.tableView.contentInset = UIEdgeInsets(top: 20,left: 0,bottom: 0,right: 0)
However, No need to do so. In the first TableViewSection, you can create a few tableView cell, just leave the first cell blank which acts as a margin below the battery bar.
I have a button in one of view controller of tab bar controller. All set up in storyboard. I registered action method like this
- (IBAction)buttonPressed:(id)sender {
NSLog(#"Button pressed");
}
The thing is that once I make left and top constraints (to force it stay in the right upper corner) touch up inside event stops working after I change rotation. So just open app in portrait mode - method is working. Change to landscape and I cannot tap button suddenly.
I've recreated problem in this easy example project.
Many thanks.
Just put the following code in you TabBarViewController class.
- (void)viewDidLayoutSubviews
{
// fix for iOS7 bug in UITabBarController
self.selectedViewController.view.superview.frame = self.view.bounds;
}
Recently I noticed same bug in my application. First I tried Slavco Petkovski method. But this caused me another bug with rotating and getting right bounds and frame, so I kept searching.
I found another solution for this problem, mainly setting autoresizing mask of view controller's view in xib. But since arrows in inspector in my Xcode (version 5.0.1) are inactive and you can't set them, you have to open xib file in text editor find autoresizingMask property for main view and change it like this:
<autoresizingMask key="autoresizingMask" widthSizable="YES" heightSizable="YES"/>
EDIT:
Alternatively you can do this in your view controller's code - same result as in changes in xcode:
self.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
