如何以编程方式创建此工具栏 [英] How to create this toolbar programmatically

问题描述

我真的很难以编程方式创建 UIToolBar （没有xib文件）。这就是我想要创造的。

I am really having a hard time creating a UIToolBar programmatically(no xib file). This is what I would like to create.

但到现在为止，我觉得我没有以正确的方式接近它。我尝试过添加一个barbuttonitem，但我不能创建效果，如png所示。我应该怎么做呢。需要帮助。

But till now, I feel I have not approached it in the right way. I have tried adding a barbuttonitem to it, but I cant create the effect as shown in the png. How should I go about it. Help needed.

编辑：我添加了更大的图像

推荐答案

UIBarButtonItem *spaceItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
[self.navigationController.toolbar setBarStyle:UIBarStyleBlackOpaque];
UIBarButtonItem *customItem = [[UIBarButtonItem alloc] initWithTitle:@"toolbar title" style:UIBarButtonItemStylePlain    target:self     action:@selector(onToolbarTapped:)];
NSArray *toolbarItems = [NSArray arrayWithObjects:spaceItem, customItem, spaceItem, nil];

[self setToolbarItems:toolbarItems animated:NO];
