自定义 UINavigationController UINavigationBar

发布于 2024-09-29 12:12:26 字数 289 浏览 5 评论 0原文

基本上我想要一个自定义的UINavigationBar。我不希望它是“半透明”或任何东西，就像图片应用程序一样。

我基本上想完全删除它，但我仍然希望能够在推送导航控制器时添加后退按钮等，并且我希望将视图（EG：UITableViewController）推到其下方。

像这样：

alt text

有什么想法可以实现这一点吗？

谢谢

@implementation UINavigationBar (background)

- (void)drawRect:(CGRect)rect {
    UIImage *image = [UIImage imageNamed:@"navigationbar.png"];
    [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
}

@end

基本上，它并没有完全透视——这是一个视觉谎言。实际执行此操作的唯一方法是重写 UINavigationBar 的 drawRect: 方法，如上所示。

@implementation UINavigationBar (background)

- (void)drawRect:(CGRect)rect {
    UIImage *image = [UIImage imageNamed:@"navigationbar.png"];
    [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
}

@end

basically, its not completely see through - its a visual lie. The only way to do it realistically is to override UINavigationBar's drawRect: method, as shown above.

要查看 UINavigationBar，如果您选择使用 UINavigationBar，只需：

self.navigationController.navigationBar.translucent=YES;

如果您希望它看起来像您发布的图像，则必须更改色调/颜色以匹配背景。

To see through the UINavigationBar, if you choose to have one, just:

self.navigationController.navigationBar.translucent=YES;

You'll have to change the tint/color to match the background if you want it to appear like the image you posted.

在您的 AppDelegate 子类 UINavigationBar 的开头，如下所示：

@interface CustomNavBar : UINavigationBar

@end

@implementation CustomNavBar

- (void)drawRect:(CGRect)rect {
    UIImage *image = [UIImage imageNamed:@"bar.png"];
    [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
}

然后在 AppDelegate 中执行此魔术：

//Set custom NavigationBar
[self.navController setValue:[[CustomNavBar alloc]init] forKeyPath:@"navigationBar"];
//Set tint to match bar.png
self.navController.navigationBar.tintColor = [UIColor colorWithRed:0.93 green:0.43 blue:0 alpha:1];
//Set font for NavigationBar
[self.navController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"Comfortaa-Bold" size:20], UITextAttributeFont, nil]];

这应该给您更多的控制权UINavigationController 外观&感觉。

At the beginning of your AppDelegate subclass UINavigationBar as below:

@interface CustomNavBar : UINavigationBar

@end

@implementation CustomNavBar

- (void)drawRect:(CGRect)rect {
    UIImage *image = [UIImage imageNamed:@"bar.png"];
    [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
}

and then in the AppDelegate do this magic:

//Set custom NavigationBar
[self.navController setValue:[[CustomNavBar alloc]init] forKeyPath:@"navigationBar"];
//Set tint to match bar.png
self.navController.navigationBar.tintColor = [UIColor colorWithRed:0.93 green:0.43 blue:0 alpha:1];
//Set font for NavigationBar
[self.navController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"Comfortaa-Bold" size:20], UITextAttributeFont, nil]];

That should give you a lot more control over UINavigationController look & feel.
