ios - 如何为 UIToolbar 添加标题？

Question

请我刚刚在我的 View 中添加了一个带有后退按钮的 UIToolbar ，我想为此 UIToolbar 添加一个标题，在界面生成器中我无法手动执行此操作，所以我应该将其添加到程序中，应该如何添加我愿意，我的 View 类是这样的:

#import "AproposView.h"


@implementation AproposView

-(IBAction)backMainView{


    [self dismissModalViewControllerAnimated:YES];

}

这个后退按钮位于 UItoolbar 中，所以我只需要添加一个标题，提前谢谢:)

#define UIColorFromRGB(rgbValue) [UIColor \
colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 \
green:((float)((rgbValue & 0xFF00) >> 8))/255.0 \
blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]    

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 202, 23)];
label.textAlignment = UITextAlignmentCenter;
label.backgroundColor = [UIColor clearColor];
label.shadowColor = UIColorFromRGB(0xe5e7eb);
//  label.shadowOffset = CGSizeMake(0, 1);
    label.textColor = UIColorFromRGB(0x717880);
    label.text = @"Edit Classes";
    label.font = [UIFont boldSystemFontOfSize:20.0];
    label.shadowColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.5];
    label.shadowOffset = CGSizeMake(0, -1.0);
    UIBarButtonItem *toolBarTitle = [[UIBarButtonItem alloc] initWithCustomView:label];
UIBarButtonItem *fixedSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:self action:nil];
toolBar.items = [NSArray arrayWithObjects:fixedSpace, toolBarTitle, fixedSpace, nil];
