UIToolBar （API+自定义工具栏）

初始化

navToolBar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, k_navBar_height)];
    navToolBar.barStyle = UIBarStyleBlackTranslucent;
//    [navToolBar setBackgroundImage:[UIImage imageNamed:@"transparentImage"] forToolbarPosition:0 barMetrics:0];
    [self.view addSubview:navToolBar];
    [navToolBar setBackgroundImage:[UIImage new]
                forToolbarPosition:UIBarPositionAny
                        barMetrics:UIBarMetricsDefault];
    [navToolBar setShadowImage:[UIImage new]
            forToolbarPosition:UIToolbarPositionAny];
    [navToolBar setBackgroundColor:[UIColor colorWithWhite:.06f alpha:.3f]];
    
    UIButton *imageBtn=[UIButton buttonWithType:UIButtonTypeCustom];
    [imageBtn setFrame:CGRectMake(0,0,50,k_navBar_height)];
    [imageBtn setBackgroundImage:[UIImage imageNamed:@"lookForPhoto_icon"] forState:UIControlStateNormal];
    [imageBtn addTarget:self action:@selector(selectedEditImg) forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *imageItem=[[UIBarButtonItem alloc] initWithCustomView:imageBtn];
    
    UIButton *rightBtn=[UIButton buttonWithType:UIButtonTypeCustom];
    [rightBtn setFrame:CGRectMake(0,0,45,k_navBar_height)];
    [rightBtn setBackgroundImage:[UIImage imageNamed:@"swich"] forState:UIControlStateNormal];
    [rightBtn addTarget:self action:@selector(cameraToggle) forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *rightItem=[[UIBarButtonItem alloc] initWithCustomView:rightBtn];
    
    UIButton *lightBtn=[UIButton buttonWithType:UIButtonTypeCustom];
    [lightBtn setFrame:CGRectMake(0,0,50,k_navBar_height)];
    [lightBtn setBackgroundImage:[UIImage imageNamed:@"lighting_close"] forState:UIControlStateNormal];
    [lightBtn setBackgroundImage:[UIImage imageNamed:@"lighting"] forState:UIControlStateSelected];
    [lightBtn addTarget:self action:@selector(changeFlash:) forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *lightItem=[[UIBarButtonItem alloc] initWithCustomView:lightBtn];
    lightBtn.tag = k_item_tag+1;
    
    UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];

自定义

    [self tranFromToolBarFrame:toolBar height:k_toolBar_height];
    toolBar.autoresizesSubviews = NO;
    toolBar.autoresizingMask = UIViewAnimationTransitionNone;
    [self.view bringSubviewToFront:toolBar];
    [self.view addSubview:toolBar];
    toolBar.backgroundFace = [UIColor blackColor];
[toolBar toolbarSetItems:[NSArray arrayWithObjects:flexSpace,@"share_icon",flexSpace,@"3d_icon",flexSpace,@"edit_icon",flexSpace,@"delete_icon",flexSpace,nil] size:toolBarSize tag:k_item_tag];
