U導航控制器沒有工作

Question

我正在製作應用程序，就像設備改變其定向模式時它改變它的視圖一樣。
第一次當視圖是肖像時，它顯示完美的SearchViewController，然後當我旋轉到風景時推動到新的視圖MapView在風景......現在當我再次改變視圖到肖像地圖旋轉到肖像......但它應該做的搜索視圖控制器......還有一件事情，當我挖掘細節泄露按鈕它應該回去搜索視圖控制器...我認爲導航控制器不能在地圖視圖中工作..

這是searchViewController

我的代碼部分

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{ 


    //return (interfaceOrientation == UIInterfaceOrientationPortrait); 
    if(interfaceOrientation == UIInterfaceOrientationPortrait|| inte rfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) 
    { 
    } 
    else { 
     MapView *mapView = [[MapView alloc] initWithNibName:@"MapView" bundle:nil]; 
     mapView.title = @"Map"; 
     [self.navigationController pushViewController:mapView animated:YES]; 
     return YES; 

    } 
    return YES; 

} 

，這是我的MapView代碼

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { 
    // Return YES for supported orientations 
    // return (interfaceOrientation == UIInterfaceOrientationLandscapeRight|| UIInterfaceOrientationLandscapeLeft); 
    if(interfaceOrientation == UIInterfaceOrientationPortrait|| interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) 
    { 
     NSLog(@"hi Potrait"); 
     [self.navigationController popViewControllerAnimated:NO]; 
     return YES; 
    } 
    else { 
    } 
    return YES; 
}

shouldAutorotateToInterfaceOrientation:是一個不正確的地方來實現任何類型的導航。您應該使用didRotateFromInterfaceOrientation:來代替。檢查當前的interfaceOrientation並在必要時按下或彈出。

在searchViewController，

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation { 
    if (UIInterfaceOrientationIsLandscape(self.interfaceOrientation)) { 
     MapView *mapView = [[MapView alloc] initWithNibName:@"MapView" bundle:nil]; 
     mapView.title = @"Map"; 
     [self.navigationController pushViewController:mapView animated:YES]; 
    } 
} 

在MapView，

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation { 
    if (UIInterfaceOrientationIsPortrait(self.interfaceOrientation)) { 
     [self.navigationController popViewControllerAnimated:NO]; 
    } 
} 

，並改變你的shouldAutorotateToInterfaceOrientation:到

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { 
    return YES; 
}
