参考 https://juejin.im/post/5d79af99e51d453c11684ce8 flutter_boost从0.1.53开始提供了swift demo，但example_swift居然跑不起来，oc的example可以。 1、直接把example Flutter下的Debug.xcconfig、Release.xcconfig、AppFrameworkInfo.plist拷过来更新分割线------------------- 这个blog的集成方法好像没集成插件- -，不过应该是move脚本有些问题没把所有framework文件cp过去，继续参考 https://www.kikt.top/posts/flutter/exists/add-flutter-to-ios/?tdsourcetag=s_pctim_aiomsg 将四个framework文件都install进来，然后和android一样调路由和通信报错1： Could not cast value of type 'TabbarController' (0x1055dc680) to 'UINavigationController' 解决： PlatformRouterImp.swift func navigationController() -> UINavigationController

Custom Navigation Bar in iOS 5

问题 I use a class to style the NavigationControllers in iOS 5. The problem I have is the moreNavigationController which is created automatically. I found a way to style the moreNavigation itself, if ([[[UIDevice currentDevice] systemVersion] intValue] >= 5.0){ [self.rootController.moreNavigationController.navigationBar setBackgroundImage: [UIImage imageNamed:@"noten_header.png"] forBarMetrics:UIBarMetricsDefault]; } but i have no clue how I style the edit view of the moreNavigationController (if

Navigation Bar Changes Height

问题 When I push my UIViewController to the screen from my previous controller it animates the change. But when it finishes loading it resizes my navigation bar and the jumpy transition makes it look bad. How can I fix this? All I'm doing is hiding the navigation bar in Controller A in viewWillAppear and showing it in Controller B in viewDidLoad . 回答1: Ok solved it. In viewDidLoad of Controller B (the view controller I'm pushing) add the following: UINavigationBar *navigationBar = self

问题 Let me explain clearly. I have a tabbarcontoller in the viewcontroller which is the main view controller of the single view application project. I added a tabbarcontroller to the viewcontroller as the subview. In the tabbarcontroller, I added two navigation controllers like below image, I have added three(named First, Second, Third) more viewcontrollers as new file. If I navigate from one viewcontroller to other in a tab using below, third = [[Third alloc] initWithNibName:@"Third" bundle:

Determine viewWillAppear from Popped UINavigationController or UITabBarController

阅读更多关于 Determine viewWillAppear from Popped UINavigationController or UITabBarController

问题 I am unable to find a way to distinguish between popping from the Nav controller stack and entering the view controller from the UITabBarController. I want to call a method in ViewWillAppear only when the view is presented from the TabBar, not when someone presses back in the navigation controller. If I wasn't using a TabBarController, I could easily get this functionally using viewDidLoad. I've tried, override func viewWillAppear(animated: Bool) { super.viewWillAppear(animated) println("View

Instantiate UIViewController programmatically without nib

阅读更多关于 Instantiate UIViewController programmatically without nib

问题 I want to create a UIViewController programmatically without the use of a nib or a storyboard. I thought it would be enough to implement the UIViewController as: class TestViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() //Add some setup code here, without it it should just be blank } } instantiate it with let vc = TestViewController(nibName: nil, bundle: nil) or just TestViewController() and then just push it: navigationController?.pushViewController(vc,

问题 My setup is simple, and my issue is not very different from this one. However to better explain it I have posted it here: NavController -> VC1 -> VC2 VC1 is root view controller of NavController. VC2 is accessible via Push segue from VC1. I want to detect, within VC1, whether: It appeared directly as root view controller (via Push) It appeared as a result of VC2 being popped I read the docs which says following should tell me if later is true. isMovingToParentViewController == NO However that

问题 I see that a similar question was asked here: How to add a right button to a UINavigationController? (among others) but its not quite what I'm looking to do and they arent solving my problem. Essentially, I've created a UIViewController called WebViewViewController with a UIWebView on it which will be shown using presentModalViewController. Essentially its a mini web browser to display a web page while keeping the user in the app rather than launching Safari. The viewController does the

问题 I want to make a custom navigation bar as like in the BestBuy App or like shown in the below given screenshot. I want this type of Navigation to be always on the top of each and every viewController. If anyone can tell me the procedure or any kind of help would be appreciated. Thanks. 回答1: write a subclass of UINavigationBar in which you do custom drawing and add subviews as needed. then tell your navigationController to use that class by initing it using initWithNavigationBarClass
