ios - 在 IOS 7 中为 UIToolBar 设置标题

Question

我在下面声明了一个 UIToolBar 按钮:

UIToolbar *toolbar = [[UIToolbar alloc] init];
toolbar.frame = CGRectMake(0.0, 0.0, self.view.frame.size.width, 64.0);

我还有一个 UIBarButtonItem，它被添加到左侧作为后退按钮。但是，我该如何向 UIToolbar 添加一个居中的标签标题呢？

Answer 1

UILabel *lblTitle = [[UILabel alloc] initWithFrame:CGRectMake(50, 50, 150, 20)];
lblTitle.backgroundColor = [UIColor clearColor];
lblTitle.textColor = [UIColor blackColor];
lblTitle.textAlignment = NSTextAlignmentLeft;
[self.view addSubview:lblTitle];
UIBarButtonItem *typeField = [[UIBarButtonItem alloc] initWithCustomView:lblTitle];   
toolBar.items = [NSArray arrayWithArray:[NSArray arrayWithObjects:backButton,spaceBar,lblTitle, nil]];

我认为这将解决您的问题。
