如何在从家庭屏幕上重开 app子时更新刺条内容? (iOS /Xcode)
原标题:How to refresh tab bar content upon reopening the app from home screen? (iOS / Xcode)

页: 1 我的法典多数是:

- (void)viewDidAppear:(BOOL)animated

因此,每当我从每个角度把所有胎儿都换成tab时,都会复发。 (好!) 尽管当我从家中听听说时,这张表格获得了更新。 我不得不转向另一个表格,然后再回来,以便装上。

任何解决办法?

最佳回答

您需要签署一份处理通知。 每一表格登记通知和处理通知的方法。 然后,我只想听你的看法。 它与一家药店一样。

-(void)viewDidLoad {

   [super viewDidLoad];

   [[NSNotificationCenter defaultCenter] addObserver:self
                                                 selector:@selector(becomeActive:)
                                                     name:UIApplicationDidBecomeActiveNotification
                                                   object:nil];
}

-(void)becomeActive:(NSNotification *)notification {
    // only respond if the selected tab is our current tab
    if (self.tabBarController.selectedIndex == 0) { // Tab 1 is 0 index, Tab 2 is 1, etc 
        [self viewDidAppear:YES];
    }

}
问题回答

或许你可以援引你的更新法。

(void)applicationDidBecomeActive:(UIApplication *)application
{
}

这种方法在您的提名中。

view view view

- (IBAction)done:(id)sender {
    [self dismissModalViewControllerAnimated:YES];
}
