pickerController.delegate=self;
pickerController.allowsEditing=YES;
[self presentViewController:pickerController animated:YES completion:nil];

#pragma mark delegate
-(void)p_w_picpathPickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{
