美图秀秀美化图片之【边框】界面设计【重大更新】

　　在进行写边框前，需要通知大家一声，整个美化图片的界面开发已经完全重写，请大家先下载最新的项目【点击下载】

效果图

在前面的开发方法中由于没有考虑许多因素，造成viewcontroller代码混乱，所以重新开发了界面，所有美化图片的独立功能都具有一个独立的viewController,这样不易混乱。另外学习到了，使用

imageNamed方法时，如果图片的格式是PNG的可以不加.png,但是其他比如jpg的图片必须加.jpg后缀。

一、链接

    else if ([text isEqualToString:@"边框"])
    {
        FWBorderViewController *vc = [[FWBorderViewController alloc] initWithImage:self.image];
        [self presentViewController:vc animated:YES completion:^{
        }];
    }

二、加载界面

1.加载要处理的图片

 //显示图片
    self.imageView = [[UIImageView alloc] initWithImage:self.image];
    self.imageView.frame = CGRectMake(0, 0, WIDTH, HEIGHT - 50 - 70);
    self.imageView.contentMode = UIViewContentModeScaleAspectFit;
    [self.view addSubview:self.imageView];

2.加载保存、取消按钮

    //保存与取消按钮的添加
    UIImage *i1 = [UIImage imageNamed:@"[email protected]"];
    self.btnClose = [UIButton buttonWithType:UIButtonTypeCustom];
    [self.btnClose setImage:i1 forState:UIControlStateNormal];
    self.btnClose.frame = CGRectMake(20, HEIGHT - kCancelHeight - 10, kCancelHeight, kCancelHeight);
    [self.btnClose addTarget:self action:@selector(btnCancelOrSaveClicked:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:self.btnClose];

    UIImage *i2 = [UIImage imageNamed:@"[email protected]"];
    self.btnSave = [UIButton buttonWithType:UIButtonTypeCustom];
    [self.btnSave setImage:i2 forState:UIControlStateNormal];
    self.btnSave.frame = CGRectMake(WIDTH - kCancelHeight - 20, HEIGHT - kCancelHeight - 10, kCancelHeight, kCancelHeight);
    [self.view addSubview:self.btnSave];
    [self.btnSave addTarget:self action:@selector(btnCancelOrSaveClicked:) forControlEvents:UIControlEventTouchUpInside];

3.加载边框样式【海报、简单、炫彩】bar

    self.styleBar = [[FWEffectBar alloc] initWithFrame:CGRectMake(50, HEIGHT - 40, 200, 20)];
    NSMutableArray *items = [[NSMutableArray alloc] initWithCapacity:0];

    NSArray *titles = [NSArray arrayWithObjects:@"海报边框", @"简单边框", @"炫彩边框", nil];
    for (int i = 0; i < [titles count]; i ++)
    {
        FWEffectBarItem *item = [[FWEffectBarItem alloc] initWithFrame:CGRectZero];
        item.title = [titles objectAtIndex:i];

        [items addObject:item];
    }

    self.styleBar.items = items;
    self.styleBar.effectBarDelegate = self;
    [self.styleBar setSelectedItem:[self.styleBar.items objectAtIndex:0]];
    [self effectBar:self.styleBar didSelectItemAtIndex:0];
    [self.view addSubview:self.styleBar];

4.加载【更多素材】视图

FWMoreEffectView *seView = [[FWMoreEffectView alloc] initWithFrame:CGRectMake(15, HEIGHT - 50 - kHeight, kWidth, kHeight)];
    [self.view addSubview:seView];

FWMoreEffectView是一个自定义的视图，比较简单，这里不多介绍。

5.加载具体边框样式

    self.borderStyleBar = [[FWEffectBar alloc] initWithFrame:CGRectMake(70, HEIGHT - 50 - kHeight, WIDTH - 70, kHeight)];
    self.borderStyleBar.effectBarDelegate = self;
    self.borderStyleBar.itemBeginX = 15.0;
    self.borderStyleBar.itemWidth = 50.0;
    self.borderStyleBar.margin = 10.0;　　//边框样式默认视图

　　　　[self setupPosterBorder];

    [self.view addSubview:self.borderStyleBar];

- (void)setupBorderEffect:(NSArray *)images
{
    FWEffectBarItem *item = nil;
    NSMutableArray *items = [[NSMutableArray alloc] initWithCapacity:0];

    for (int i = 0; i < [images count]; i++)
    {
        item = [[FWEffectBarItem alloc] initWithFrame:CGRectMake((kWidth + kSpace) * i + 10, 0, kWidth, kHeight)];
        item.backgroundColor = [UIColor whiteColor];
        UIImage *img1 = [UIImage scaleImage:[UIImage imageNamed:[images objectAtIndex:i]] targetWidth:50];

        [item setFinishedSelectedImage:img1 withFinishedUnselectedImage:img1];
        [items addObject:item];
    }

    self.borderStyleBar.items = items;
}

定义一个加载具体边框样式的方法，传递一个样式图片数组，然后调用下面3个方法实现显示

//简单边框视图
- (void)setupSimpleBorderView
{
    [self setupBorderEffect:[NSArray arrayWithObjects:@"border_baikuang_a.jpg", @"border_baolilai_a.jpg", @"border_heikuang_a.jpg", @"border_luxiangji_a.jpg", @"border_onenight_a.jpg", @"border_simple_15.jpg", @"border_simple_16.jpg", @"border_simple_17.jpg", @"border_simple_18.jpg", @"border_simple_19.jpg",nil]];
}

//海报边框视图
- (void)setupPosterBorder
{
    [self setupBorderEffect:[NSArray arrayWithObjects:@"pb1", @"pb2", @"pb3", @"pb4", @"pb5", @"pb6", @"pb7", @"pb8", @"pb9", @"pb10",nil]];
}

//炫彩边框视图
- (void)setupDazzleBorder
{
    [self setupBorderEffect:[NSArray arrayWithObjects:@"xborder_aixin_a.jpg", @"xborder_guangyun_a.jpg", @"xborder_qisehua_a.jpg", @"xborder_wujiaoxing_a.jpg", @"xborder_xueye_a.jpg", @"xborder_yinhe_a.jpg",nil]];
}

我们通过给borderStyleBar不同的items来实现显示不同的样式item。

6.实现bar 的委托

#pragma mark - FWEffectBarDelegate
- (void)effectBar:(FWEffectBar *)bar didSelectItemAtIndex:(NSInteger)index
{
    if (bar == self.styleBar)
    {
        switch (index) {
            case 0:
                [self setupPosterBorder];
                break;

            case 1:
                [self setupSimpleBorderView];
                break;

            case 2:
                [self setupDazzleBorder];
                break;
        }
    }
    else
    {
        FWEffectBarItem *item = (FWEffectBarItem *)[bar.items objectAtIndex:index];
        item.ShowBorder = YES;
    }

}

当我们点击styleBar时，切换边框样式类型，当我们点击borderStyleBar时，应用具体的边框样式，且被选中的样式出现边框。

隐藏状态栏

//隐藏状态栏
- (BOOL)prefersStatusBarHidden
{
    return YES;
}

OVER.THANKS!
