更改 UIBarButtonSystemItemCancel 的颜色

发布于 2024-10-15 23:36:59 字数 125 浏览 6 评论 0原文

如果我使用 UIBarButtonSystemItemCancel，它的颜色将设置为导航栏的颜色。但是，在照片应用程序中，“取消”按钮显示为蓝色背景。我怎样才能将 UIBarButtonSystemItemCancel 设置为蓝色背景？

您可以使用图像作为按钮图像

UIImage *buttonImage = [UIImage imageNamed:@"image.png"];

//create the button and assign the image
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:buttonImage forState:UIControlStateNormal];


//create a UIBarButtonItem with the button as a custom view
//UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithCustomView:button];

[button addTarget:self action:@selector(clickActionItem:) forControlEvents:UIControlEventTouchUpInside];

UIBarButtonItem *rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button ];




self.navigationItem.rightBarButtonItem = rightBarButtonItem;

your can use image as button image as

UIImage *buttonImage = [UIImage imageNamed:@"image.png"];

//create the button and assign the image
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:buttonImage forState:UIControlStateNormal];


//create a UIBarButtonItem with the button as a custom view
//UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithCustomView:button];

[button addTarget:self action:@selector(clickActionItem:) forControlEvents:UIControlEventTouchUpInside];

UIBarButtonItem *rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button ];




self.navigationItem.rightBarButtonItem = rightBarButtonItem;

将 theNavigationController.navigationBar.barStyle 设置为 UIBarStyleBlackTranslucent

theNavigationController.navigationBar.barStyle = UIBarStyleBlackTranslucent;

，按钮默认为蓝色。

set the theNavigationController.navigationBar.barStyle to UIBarStyleBlackTranslucent

theNavigationController.navigationBar.barStyle = UIBarStyleBlackTranslucent;

and the buttons will be blue by default.

有比使用图像更好的方法。 UISegmentedControl 可以配置为看起来像 UIBarButtonItem，并且 UISegmentedControl 具有 TintColor 属性。

UISegmentedControl *button = [[[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:itemTitle, nil]] autorelease];
    button.momentary = YES;
    button.segmentedControlStyle = UISegmentedControlStyleBar;
    button.tintColor = color;
    [button addTarget:theTarget action:selector forControlEvents:UIControlEventValueChanged];

    UIBarButtonItem *removeButton = [[[UIBarButtonItem alloc] initWithCustomView:button] autorelease];

我建立了一个 UIBarButtonItem 类别< /a> 这样就可以了。

There is a better way than using an image. The UISegmentedControl can be configured to look just like a UIBarButtonItem and UISegmentedControl has a tintColor property.

UISegmentedControl *button = [[[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:itemTitle, nil]] autorelease];
    button.momentary = YES;
    button.segmentedControlStyle = UISegmentedControlStyleBar;
    button.tintColor = color;
    [button addTarget:theTarget action:selector forControlEvents:UIControlEventValueChanged];

    UIBarButtonItem *removeButton = [[[UIBarButtonItem alloc] initWithCustomView:button] autorelease];

I built a UIBarButtonItem category that'll do this.
