ios - 将 IBAction 分配给自定义 navigationBarItem

Question

我使用自定义 UIViews 作为 navigationBarItem（就像 Facebook 在他们的 iOS 应用程序中那样）。

UIImageView *linkesMenu = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"187menu.png"]];
UIBarButtonItem *barItem = [[UIBarButtonItem alloc] initWithCustomView:linkesMenu];

barItem.action = @selector(MenuSlider:);
self.navigationItem.leftBarButtonItem = barItem;

我尝试了这个和其他一些东西，但没有任何效果。

Answer 1

尝试先将图像放入按钮中：

UIImage *theImage = [UIImage imageNamed:@"image.png"];
UIButton *theButton = [UIButton buttonWithType:UIButtonTypeCustom];
theButton.bounds = CGRectMake(0, 0, theImage.size.width, theImage.size.height);
[theButton setImage:theImage forState:UIControlStateNormal];
UIBarButtonItem *theBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:theButton];


[theButton addTarget:self action:@selector(MenuSlider:) forControlEvent:UIControlEventTouchUpInside];
self.navigationItem.leftBarButtonItem = barItem;
