Question

我对FPPopover库的实现有疑问。

我遇到的问题与其他帖子类似：Same issue on StackOverFlow

不幸的是，对popover控制器的引用并不能解决我的问题。

在我未来的控制器上，单击操作按钮时会动态加载UITableView。这是我的代码：

- (IBAction)displayAlternateNicknames:(id)sender{
  PXAlternativeNicknamesViewController * suggestionsVC=    [[UIStoryboard storyboardWithName:[ViewsParamsSingleton sharedLoginSignUpStoryBoard] bundle:nil] instantiateViewControllerWithIdentifier:NicknameSuggestionsStoryBoardID];
  suggestionsVC.title=@"Suggestions";
  suggestionsVC.nicknameSuggestions=self.nicknameSuggestions;
  suggestionsVC.callerVC=self;

  //our popover
  suggestionsPopover = [[FPPopoverController alloc] initWithViewController:suggestionsVC];

  suggestionsPopover.contentSize = CGSizeMake(200,200);

  //the popover will be presented from the okButton view
  [suggestionsPopover presentPopoverFromView:sender];
}

这是我在生产中工作的实施。试试吧。可能只是你没有正确设置所有属性。

// MyViewController.m
@interface MyViewController ()

@property(nonatomic, strong) FPPopoverController *popover;

@end

...

// Instantiate popover

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
LoginViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:@"LoginViewController"];

if (self.popover) {
    [self.popover dismissPopoverAnimated:NO];
    self.popover = nil;
}

self.popover = [[FPPopoverController alloc] initWithViewController:viewController];
self.popover.contentSize = viewController.size;
self.popover.border = NO;
self.popover.arrowDirection = FPPopoverNoArrow;
self.popover.tint = FPPopoverRedTint;

[self.popover presentPopoverFromView:self.loginButton];

如果问题仍然存在，我找到了另一个可能有帮助的答案here。基本上，您必须为FPPopover禁用ARC。我不确定如何使用Cocoapods这样做，因此您可能只需将库直接复制并粘贴到项目中。我知道这不是一个理想的解决方案，但我认为它值得一试。

另一种可能性是创建FPPopover的实例变量并以这种方式引用它。例如：

@property (nonatomic, strong) FPPopover *popover;
...
- (FPPopover *)popover {
    if(!_popover){
        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
        LoginViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:@"LoginViewController"];

        _popover.contentSize = viewController.size;
        _popover.border = NO;
        _popover.arrowDirection = FPPopoverNoArrow;
        _popover.tint = FPPopoverRedTint;
    }
    return _popover;
}
...
-(void)buttonTapped:(UIButton *)sender{
    [self.popover presentPopoverFromView:sender];
}

FPPopoverController不会弹出
