我已按编程方式添加 Map<String, String> params = new HashMap<String, String>();
params.put("grant_type", "password");
params.put("username", email);
params.put("password", password);
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, AppConfig.URL_LOGIN, new JSONObject(params), new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
}){
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/x-www-form-urlencoded");
return headers;
}
};
，如下所示。有用。但是，当我尝试使用pageviewController删除时，它不会删除它。
添加pageViewController
[self.pageViewController.view removeFromSuperview];删除pageViewController
self.pageViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"PageViewController"];
self.pageViewController.dataSource = self;
self.pageViewController.delegate = self;
PageContentViewController *startingViewController = [self viewControllerAtIndex:0];
NSArray *viewControllers = @[startingViewController];
[self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];
[self addChildViewController:self.pageViewController];
[self.view addSubview:self.pageViewController.view];
[self.pageViewController didMoveToParentViewController:self];
答案 0 :(得分：1)
使用以下说明删除pageViewController：
[self.pageViewController willMoveToParentViewController:nil];
[self.pageViewController.view removeFromSuperview];
[self.pageViewController removeFromParentViewController];
