iOS基础-UItoolBar简单使用

自定义如图工具栏

    //创建工具栏
    NSMutableArray *items = [[NSMutableArray alloc] initWithCapacity:3];
    UIBarButtonItem *confirmBtn = [[UIBarButtonItem alloc] initWithTitle:@"确定" style:UIBarButtonItemStyleDone target:self action:@selector(confirmPickView)];
    UIBarButtonItem *flexibleSpaceItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
    
    titleItem = [[UIBarButtonItem alloc] initWithTitle:@"用户类型" style:UIBarButtonItemStylePlain target:nil action:nil];
    
    //titleItem.tintColor = [UIColor blackColor];
    //titleItem.appearance.tintColor = [UIColor redColor];
    
    [titleItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor blackColor],UITextAttributeTextColor,[UIColor clearColor],UITextAttributeTextShadowColor, nil] forState:UIControlStateNormal];
//
//    [titleItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor blackColor],UITextAttributeTextColor,[UIColor clearColor],UITextAttributeTextShadowColor, nil] forState:UIControlStateDisabled];
    
    titleItem.enabled = NO;
    titleItem.tag = 1;
    
    UIBarButtonItem *cancelBtn = [[UIBarButtonItem alloc] initWithTitle:@"取消" style:UIBarButtonItemStyleBordered target:self action:@selector(pickerHide)];
    [items addObject:cancelBtn];
    [items addObject:flexibleSpaceItem];
    [items addObject:titleItem];
    [items addObject:flexibleSpaceItem];
    [items addObject:confirmBtn];
    
    if (toolBar==nil) {
        toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, self.view.frame.size.height, 320, 44)];
        [toolBar setBackgroundImage:[UIImage imageNamed:@"search_buttom"] forToolbarPosition:0 barMetrics:0];
    }
    //toolBar.hidden = YES;
    
    toolBar.barStyle = UIBarStyleBlackTranslucent;
    toolBar.items = items;
    [self.view addSubview:toolBar];
