How can we remove the shadow from the left sideMenu from react-native-navigation v2.
There is not support yet, but if you want to fork or edit the implementation here is the line https://github.com/wix/react-native-navigation/blob/a591fe4476ca152a336022e2570431b677f60225/lib/ios/RNNSideMenu/MMDrawerController/MMDrawerController.m#L220
[self setAnimationVelocityLeft:MMDrawerDefaultAnimationVelocity];
[self setAnimationVelocityRight:MMDrawerDefaultAnimationVelocity];
- [self setShowsShadow:YES];
+ [self setShowsShadow:NO];
[self setShouldStretchLeftDrawer:YES];
[self setShouldStretchRightDrawer:YES];

I'm creating a generic reusable UIViewController component that people can add to their applications. It requires a navigation bar at the top where it will add some buttons.
I can easily create a navigationBar and add the buttons, but if the developer using my component is adding the view as part of an existing navigation structure, they might end up with 2 navigation bars.
In other words, if my view is loaded with:
[self.navigationController pushViewController:controller animated:YES];
then it should not add a navigationbar and use what's already there. If the view is loaded with:
[self presentModalViewController:controller animated:YES];
then it should add its own navbar.
Without requiring the developer that uses my controller to do something like a useNavBar:YES, is there a way to do this automatically?
Something like a [self isRunningInsideANavigationController] or [self hasNavigationBar] would do.
You could use self.navigationController for that purpose. It will return nil or the navigationController.
How to add UINavigationController to xCode Tab Bar Application Delegate?
My structure is based on xCode Tab Bar Application Delegate, with 2 tabs, First View & Second View respectively. For First View, I added a UITableView. I just want to make use of UINavigationController function [self.navigationController pushViewController:animated:] to push a subview and allow a navigation bar to be shown in subview. After pushing the subview, the tab bar must still be there.
Sounds simple, but I have no idea how to achieve it. Please help.
I started with a Window-based template instead and did this to achieve the same thing.
I created my NavigationControllers and TabBarController in my app delegate manually.
In your:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
Add this:
//Seeting up the Navigation controllers and pushing our TableView controllers.
UINavigationController *unvc1 = [[UINavigationController alloc] init];
UINavigationController *unvc2 = [[UINavigationController alloc] init];
[unvc1 pushViewController:someViewController1 animated:NO];
[unvc2 pushViewController:someViewController2 animated:NO];
[someViewController1 release];[someViewController2 release];//Releasing our TableView controllers.
//Setting up the TabBar controller and pushing our Navigation controllers.
UITabBarController *tbvc = [[UITabBarController alloc] init];
tbvc.viewControllers = [NSArray arrayWithObjects:unvc1, unvc2, nil];
[unvc1 release];[unvc2 release]; //releasing our Navigation controllers.
I hope this helps.
I did this using presentModalViewController:animated . I added tabBar Controller in the modalView. In the method didSelectRowAtIndexPath use this presentModalViewController:animated .I might not be perfect but I had the same problem, but now my app works as I need.
Has Presenting modal view controller in iOS 4.3 for iPad changed?
I created a new view application, then created a new UIViewControllerSubclass called "One", I then changed the background of One.xib to black, in the applications view controller's viewDidLoad method I placed in the code below. I ran the project in the simulator and receive the log that the "Code has run..."
The project can be downloaded from here....Download Source Code of Project
#import "One.h"
- (void)viewDidLoad
{
One *newItemViewController = [[One alloc] initWithNibName:#"One" bundle:nil];
newItemViewController.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentModalViewController:newItemViewController animated:YES];
[newItemViewController release];
NSLog(#"Code has run...");
}
Try putting your this in the viewDidAppear method instead of viewDidLoad.
I have a textview which contains chat history obtained from a server.The chat history is being constantly updated through a thread which I had started in a previous view. My problem is how do I constantly update my UITextView to reflect the changes?
self.textView.text = [[NSString alloc]initWithFormat:#"%#",chatHistory];
I use something like this:
NSString *newMessage = [NSString stringWithFormat:#"%#\n%#", [textView text], newChat];
[textView setText:newMessage];
also make sure your GUI updates are on the main application thread.
[self performSelectorOnMainThread:#selector(updateMyGui) withObject:nil waitUntilDone:NO];
My view hierarchy containing the view from a MPMoviePlayerController vanishes the moment I present a Modal View Controller.
Instead of displaying a view with a movie and controls it depicts an earlier subview beneath it. I checked the subview array of the main view controller and all views including the movie player view exits.
Forcibly adding the movie player view after the modal view controller is done does not bring movie player view back on top.
Would welcome any suggestions/thoughts ?
your problem isn't specific to the MPMoviePlayerController. any time you present a modal view controller, all of the views from other view controllers beneath it disappear.
try it out with just a couple of simple view controllers.
in the app delegate, set your window background color to red:
[self.window setBackgroundColor:[UIColor redColor]];
then add a view controller with a green background:
UIViewController *vc = [[UIViewController alloc] init];
[[vc view] setBackgroundColor:[UIColor greenColor]];
self.window.rootViewController = vc;
finally, create another view controller with a transparent background, and present it modally:
UIViewController *vc2 = [[UIViewController alloc] init];
[[vc2 view] setBackgroundColor:[UIColor clearColor]];
[vc presentModalViewController:vc2 animated:YES];
you'd expect to see the green VC through the clear VC, but instead you see red (ie, you see the window).
