UInavigation控制器不起作用

如何解决UInavigation控制器不起作用

| 我正在制作应用程序，就像设备每次更改其方向模式时都会更改其视图一样。 首先，当视图为纵向时，它显示完美的SearchViewController，然后当我旋转为横向时，将其推入横向的新视图MapView中。现在，当我再次将视图更改为纵向时，地图将旋转为纵向...但应该是做搜索视图控制器...，当我点击详细信息披露按钮时，还有一件事情应该回到搜索视图控制器...我认为导航控制器在地图视图中不起作用。 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;  
}

    

解决方法

        

shouldAutorotateToInterfaceOrientation:

是实施任何类型导航的不正确位置。您应该改用

didRotateFromInterfaceOrientation:

。检查当前的

interfaceOrientation

，必要时推动或弹出。 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];
    }
}

然后将您的

shouldAutorotateToInterfaceOrientation:

更改为

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