[操作系统]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:@"btn_cancel_a@2x.png"];  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:@"btn_ok_a@2x.png"];  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;}
