在IOS 7中将标题设置为UIToolBar

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作为后退按钮添加到左侧.但是,如何在UIToolbar中添加居中的标签标题？

解决方法

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]];

这会解决你的问题.
