iOS - 更改UIBarButtonItem的高度 [英] iOS - Changing UIBarButtonItem's height

问题描述

UIToolbar有一个很好的调整大小的选项（self.navigationController.toolbar.frame）我想知道是否有人知道如何改变UIBarButtonItem的高度？

<我有一个高度为117像素的自定义工具栏，到目前为止我还没有找到修改工具栏上按钮的方法。此外，我需要它作为工具栏，因为显示的视图覆盖了另一个动画视图（剪切场景样式），而我在第一个视图中设置资源，工具栏需要在所有它期间保持在顶部。

解决方案

我实际上遇到过这个问题，我唯一能想到的就是利用initWithCustomView并传入一个带有定义框架的UIButton。 / p>

  UIButton * button = [UIButton buttonWithType：UIButtonTypeCustom]; 
 
 / * 
 *插入按钮样式
 * / 
 
 button.frame = CGRectMake（0,0，宽度，高度）; 
 
 UIBarButtonItem * barButtonItem = [[UIBarButtonItem alloc] initWithCustomView：button]; 
  

否则UIBarButtonItem只有一个可以设置的width属性，但遗憾的是不是height属性。我用initWithCustomView做的另一件好事就是传入一个带有按钮的工具栏和其他东西，比如活动指示器。希望这会有所帮助。

UIToolbar has a nice option for resizing (self.navigationController.toolbar.frame) I'm wondering if anyone knows of a way to change the height of a UIBarButtonItem?

I have a custom toolbar with a height of 117 pixels and so far I haven't found a way of modifying the buttons on the toolbar. Also I need it to be a toolbar because the displayed view gets covered with another animated view (cut scene style) while I setup assets in the first view and the toolbar needs to stay on top during all of it.

解决方案

I've actually run into this myself and the only thing I could come up with was leveraging initWithCustomView and passing in a UIButton with a defined frame.

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];

/*
* Insert button styling
*/

button.frame = CGRectMake(0, 0, width, height);

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

Otherwise UIBarButtonItem only has a width property that can be set but unfortunately not a height property. Another nifty thing I've done with initWithCustomView is to pass in a toolbar with a button and other things like activity indicators. Hope this helps.
