如何为 UISplitViewController 在纵向模式下显示的 UIBarButtonItem 提供自定义视图？

当我们使用 UISplitViewController 进入纵向模式时，它们将为我们提供一个 barButtonItem。如何为该 barButtonItem 使用 customView？

我尝试了以下方法。如果我从纵向开始，它会起作用。但如果我去风景，当我回来时它就会崩溃。

在 viewDidLoad 中

UIImage *image = [UIImage imageNamed:@"home.png"];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.bounds = CGRectMake(0, 0, 22.00, 22.00);    
[button setImage:image forState:UIControlStateNormal];
[button addTarget:self action:@selector(showHomeDetails) forControlEvents:UIControlEventTouchDown];    
homeButton = [[UIBarButtonItem alloc] initWithCustomView:button];
[button release];

然后在 willHideViewController 中

barButtonItem = homeButton;

我该做什么？或者有替代解决方案吗？

When we go portrait mode while using a UISplitViewController, they will provide us by a barButtonItem. How can I use a customView for that barButtonItem?

I tried the following way. It works if I start with portrait orientation. But if I go landscape and when I come back it crashes.

In viewDidLoad

UIImage *image = [UIImage imageNamed:@"home.png"];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.bounds = CGRectMake(0, 0, 22.00, 22.00);    
[button setImage:image forState:UIControlStateNormal];
[button addTarget:self action:@selector(showHomeDetails) forControlEvents:UIControlEventTouchDown];    
homeButton = [[UIBarButtonItem alloc] initWithCustomView:button];
[button release];

Then in willHideViewController

barButtonItem = homeButton;

What shud I do? OR is there an alternate solution?

在 willHideViewController 中像这样重写它并完成。

UIImage *image = [UIImage imageNamed:@"news.png"];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.bounds = CGRectMake(0, 0, image.size.width, image.size.height );    
[button setImage:image forState:UIControlStateNormal];
[button addTarget:self action:@selector(showSideTable) forControlEvents:UIControlEventTouchUpInside];    
[barButtonItem setCustomView:button];

主要更改已删除[按钮释放]。

Rewrote it like this inside the willHideViewController and its done.

UIImage *image = [UIImage imageNamed:@"news.png"];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.bounds = CGRectMake(0, 0, image.size.width, image.size.height );    
[button setImage:image forState:UIControlStateNormal];
[button addTarget:self action:@selector(showSideTable) forControlEvents:UIControlEventTouchUpInside];    
[barButtonItem setCustomView:button];

Main change is removed [button release].

我相信应该是这样的：

UIImage *image = [UIImage imageNamed:@"home.png"];
UIImageView *imageView = [UIImageView initWithImage:image];
homeButton = [[UIBarButtonItem alloc] initWithCustomView:imageView];
[homeButton addTarget:self action:@selector(showHomeDetails)];
[homeButton setBounds:CGRectMake(0, 0, 22.00, 22.00)];

希望这能解决您的问题

I believe it should be this:

UIImage *image = [UIImage imageNamed:@"home.png"];
UIImageView *imageView = [UIImageView initWithImage:image];
homeButton = [[UIBarButtonItem alloc] initWithCustomView:imageView];
[homeButton addTarget:self action:@selector(showHomeDetails)];
[homeButton setBounds:CGRectMake(0, 0, 22.00, 22.00)];

Hope this solves your problem

假设图像是您正在寻找的自定义视图：

- (void)splitViewController:(UISplitViewController *)splitController willHideViewController:(UIViewController *)viewController withBarButtonItem:(UIBarButtonItem *)barButtonItem forPopoverController:(UIPopoverController *)popoverController
{
    [barButtonItem setImage:[UIImage imageNamed:@"awesome_menu_icon.png"]];
    [[self navigationItem] setLeftBarButtonItem:barButtonItem];
}

Assuming an image is the custom view you're looking for:

- (void)splitViewController:(UISplitViewController *)splitController willHideViewController:(UIViewController *)viewController withBarButtonItem:(UIBarButtonItem *)barButtonItem forPopoverController:(UIPopoverController *)popoverController
{
    [barButtonItem setImage:[UIImage imageNamed:@"awesome_menu_icon.png"]];
    [[self navigationItem] setLeftBarButtonItem:barButtonItem];
}
