效果如圖

目前旋轉和銳化的界面還沒做。

編輯模塊包含圖片裁剪、旋轉、銳化。

一、點擊美化圖片首頁【編輯】，進入具體操作界面

  FWFunctionViewController *vc = [[FWFunctionViewController alloc] initWithImage:self.image type:FWBeautyProcessTypeEdit];
  [self presentViewController:vc animated:YES completion:^{
  }];
  [vc displayEditPage];

二、配置要處理圖片

  UIImage *img = [UIImage scaleImage:self.image targetWidth:WIDTH];
        CGFloat x = 0;
        CGFloat y = 0;
        //HEIGHT - 115
        if (img.size.height > HEIGHT - 115)
        {
            img = [UIImage scaleImage:img targetHeight:HEIGHT - 115];
            x = WIDTH / 2 - img.size.width /2;
        }
        else
        {
            y =( HEIGHT - 115) / 2 - img.size.height / 2;
        }
        self.imageView.image = img;
        self.imageView.frame = CGRectMake(x, y, img.size.width, img.size.height);

三、配置bar

self.styleBar.frame = CGRectMake(100, HEIGHT - 55, 160, 55);
        
        autoDict = [[FWCommonTools getPlistDictionaryForButton] objectForKey:@'Edit'];

  NSArray *normalImageArr = [autoDict objectForKey:@'normalImages'];
    NSArray *hightlightedImageArr = [autoDict objectForKey:@'HighlightedImages'];
    NSArray *textArr = [autoDict objectForKey:@'Texts'];
    
    NSMutableArray *arr = [[NSMutableArray alloc] initWithCapacity:0];
    for (int i = 0; i < [textArr count]; i++)
    {
        FWEffectBarItem *item = [[FWEffectBarItem alloc] initWithFrame:CGRectZero];
        [item setFinishedSelectedImage:[UIImage imageNamed:[hightlightedImageArr objectAtIndex:i]] withFinishedUnselectedImage:[UIImage imageNamed:[normalImageArr objectAtIndex:i]] ];
        item.title = [textArr objectAtIndex:i];
        [arr addObject:item];
    }
    
    self.styleBar.items = arr;
    
    self.styleBar.effectBardelegate = self;
    [self.styleBar setSelectedItem:[self.styleBar.items objectAtIndex:0]];
    [self.view addSubview:self.styleBar];
    [self effectBar:self.styleBar didSelectItemAtIndex:0];

四、配置按鈕

UIButton *btnReset = [UIButton buttonWithType:UIButtonTypeSystem];
    [btnReset setTitle:@'重置' forState:UIControlStateNormal];
    
    btnReset.frame = CGRectMake(30, HEIGHT - 95, 50, 30);
    [btnReset.titleLabel setFont:[UIFont systemFontOfSize:12.0]];
    [btnReset setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
    btnReset.layer.borderWidth = 0.5;
    btnReset.layer.cornerRadius = 15.0;
    btnReset.layer.borderColor = [UIColor whiteColor].CGColor;
    btnReset.backgroundColor = [UIColor colorWithRed:26 / 255.0 green:26/ 255.0 blue:26/ 255.0 alpha:0.8];
    [self.view addSubview:btnReset];
    
    UIButton *btnScaleType = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [btnScaleType setTitle:@'比例：自由' forState:UIControlStateNormal];
    [btnScaleType setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
    btnScaleType.frame = CGRectMake(100, HEIGHT - 95, 80, 30);
    [btnScaleType.titleLabel setFont:[UIFont systemFontOfSize:12.0]];
    btnScaleType.layer.borderWidth = 0.5;
    btnScaleType.layer.cornerRadius = 15.0;
    btnScaleType.layer.borderColor = [UIColor whiteColor].CGColor;
    [btnScaleType addTarget:self action:@selector(scaleTypeClick:) forControlEvents:UIControlEventTouchUpInside];
    
    [self.view addSubview:btnScaleType];
    
    UIButton *btnConfirm = [UIButton buttonWithType:UIButtonTypeSystem];
    btnConfirm.backgroundColor = [UIColor blueColor];
    [btnConfirm setImage:[UIImage imageNamed:@'icon_clip_confim@2x.png'] withTitle:@'確定裁剪' forState:UIControlStateNormal];
    [btnConfirm setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
    btnConfirm.layer.cornerRadius = 15.0;
    btnConfirm.frame = CGRectMake(240, HEIGHT - 95, 90, 30);
    [self.view addSubview:btnConfirm];
    
    self.imageView.hidden = YES;
    self.cropView = [[FWCropView alloc] initWithFrame:self.imageView.frame];
    [self.cropView setImage:self.image];
    [self.view addSubview:self.cropView];
    [self.imageView removeFromSuperview];

五、配置裁剪比例視圖

    self.scaleScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, HEIGHT - 55 - 10 - 30 - 10 - 52, WIDTH, 52)];
    self.scaleScrollView.contentSize = CGSizeMake(WIDTH * 1.5, 52);
    self.scaleScrollView.bounces = NO;
    self.scaleScrollView.backgroundColor = [UIColor colorWithRed:26 / 255.0 green:26/ 255.0 blue:26/ 255.0 alpha:0.8];
    self.scaleScrollView.alpha = 0.9;
    self.scaleScrollView.showsHorizontalScrollIndicator = YES;
    NSDictionary *dict = [[FWCommonTools getPlistDictionaryForButton] objectForKey:@'scaleMode'];
    NSArray *normalImageArr = [dict objectForKey:@'normalImages'];
    NSArray *hightlightedImageArr = [dict objectForKey:@'HighlightedImages'];
    NSArray *textArr = [dict objectForKey:@'Texts'];
    
    CGFloat beginX = 20.0;
    CGFloat width = 30;
    CGFloat height = 48;
    CGFloat margin = 50;
    FWEffectBarItem *item = nil;
    
    for (int i = 0; i < [normalImageArr count]; i++)
    {
        item = [[FWEffectBarItem alloc] initWithFrame:CGRectMake(beginX + i * (margin + width), 2, width, height)];
        [item setFinishedSelectedImage:[UIImage imageNamed:[hightlightedImageArr objectAtIndex:i]] withFinishedUnselectedImage:[UIImage imageNamed:[normalImageArr objectAtIndex:i]]];
        item.title = [textArr objectAtIndex:i];
        [self.scaleScrollView addSubview:item];
    }
    [self.view addSubview:self.scaleScrollView];
