UInavigationcontroller没有用

Question

我正在制作app，就像设备改变它的方向模式一样，它改变了它的视图 首先，当视图是肖像时，它显示完美的SearchViewController，然后当我旋转到横向它推送到景观中的新视图MapView ...现在当我再次将视图更改为肖像时，地图旋转为肖像......但它应该是做搜索视图控制器...还有一件事，当我点击详细信息披露按钮时，它应该回到搜索视图控制器...我认为导航控制器不能在地图视图中工作..

这是我的searchViewController的代码部分

- (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;

}  

这是我的MapView代码

- (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:是一个不正确的地方，可以实现任何类型的导航。您应该在didRotateFromInterfaceOrientation:中执行此操作。检查当前interfaceOrientation并在必要时按或弹出。

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];
    }
}

将您的shouldAutorotateToInterfaceOrientation:改为

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