我使用的是委託UITabbarController
像這樣的過渡動畫:ViewDidAppear不會被調用
-(BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController {
NSArray *tabViewControllers = tabBarController.viewControllers;
UIView * fromView = tabBarController.selectedViewController.view;
UIView * toView = viewController.view;
if (fromView == toView)
return TRUE;
NSUInteger fromIndex = [tabViewControllers indexOfObject:tabBarController.selectedViewController];
NSUInteger toIndex = [tabViewControllers indexOfObject:viewController];
[UIView transitionFromView:fromView
toView:toView
duration:0.3
options: toIndex > fromIndex ? UIViewAnimationOptionTransitionFlipFromLeft : UIViewAnimationOptionTransitionFlipFromRight
completion:^(BOOL finished) {
if (finished) {
tabBarController.selectedIndex = toIndex;
}
}];
return true;
}
只有這打破了我的整個ViewDidAppear
上的意見。我重置UIWebView
到主頁選項卡之間切換時,但這不工作了。有什麼建議麼?這裏是我的VieDidLoad
:
-(void)viewDidAppear:(BOOL)animated{
[super viewDidAppear:animated];
_progressProxy = [[NJKWebViewProgress alloc] init];
_webView.delegate = _progressProxy;
_progressProxy.webViewProxyDelegate = self;
_progressProxy.progressDelegate = self;
[self loadSite];
[TestFlight passCheckpoint:@"Bekijkt homepage"];
}
[self loadSite];
被定義爲:在提前
-(void)loadSite
{
NSString *dealerurl = [[NSUserDefaults standardUserDefaults] stringForKey:@"name_preference"];
NSString *urlAddress= @"http://www.sportdirect.com/shop/";
NSURLRequest *req = [[NSURLRequest alloc] initWithURL:[NSURL URLWithString:urlAddress]];
[_webView loadRequest:req];
[[_webView scrollView] setBounces: NO];
}
感謝。
你的代碼看起來OK,設置viewDidAppear一個Breakoint並嘗試與viewWillAppear中 –
@DavidG更換您的viewDidAppear梅索德。原來它居然達到斷點'自loadsite'設置每一個開關。它只是不改變'UIWeview' .. –
OK,在第一行設置一個斷點 - (空)loadSite,檢查值,檢查是否有些東西是零。我想補充一點梅索德認識到,如果沒有web視圖加載失敗: - (無效)webView的:(UIWebView的*)webView的didFailLoadWithError:(NSError *)錯誤{ 的NSLog(@ 「錯誤」); } –
