  • 新浪微博客户端(11)-自定义checkBox

    在最后一个欢迎界面上添加一个CheckBox.

    // 2.添加4个UIImageView
        for (int i = 0; i < NEW_FEATURE_NUMS; i++) {
           UIImageView *imageView = [[UIImageView alloc] init];
            imageView.size = scrollView.size;
            imageView.y = 0;
            imageView.x = i * scrollW;
            NSString *imageName = [NSString stringWithFormat:@"new_feature_%d",i+1];
            imageView.image = [UIImage imageNamed:imageName];
            [scrollView addSubview:imageView];
            
            // 如果是最后一张图片,则添加进入按钮
            if (i == NEW_FEATURE_NUMS - 1) {
                [self setupEnterBtn:imageView];
            }
            
        }
    /** 添加分享checkbox及进入微博按钮 */
    - (void)setupEnterBtn:(UIImageView *)imageView {
    
        // 0.设置imageView可以交互
        imageView.userInteractionEnabled = YES;
        
        // 1.添加shareBtn
        UIButton *shareBtn = [[UIButton alloc] init];
        [shareBtn setImage:[UIImage imageNamed:@"checkbox_unchecked"] forState:UIControlStateNormal];
        [shareBtn setImage:[UIImage imageNamed:@"checkbox_checked"] forState:UIControlStateSelected];
        
        [shareBtn setTitle:@"分享到微博" forState:UIControlStateNormal];
        [shareBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
        shareBtn.titleLabel.font = [UIFont systemFontOfSize:14];
        shareBtn.titleEdgeInsets = UIEdgeInsetsMake(0, 16, 0, 0);
        shareBtn.width = 200;
        shareBtn.height = 44;
        shareBtn.centerX = imageView.width * 0.5;
        shareBtn.centerY = imageView.height * 0.75;
        [shareBtn addTarget:self action:@selector(shareBtnClick:) forControlEvents:UIControlEventTouchUpInside];
        
        [imageView addSubview:shareBtn];
        
        
        // 2.添加进入微博按钮
        UIButton *enterBtn = [[UIButton alloc] init];
        [enterBtn setBackgroundImage:[UIImage imageNamed:@"new_feature_button"] forState:UIControlStateNormal];
        [enterBtn setBackgroundImage:[UIImage imageNamed:@"new_feature_button_highlighted"] forState:UIControlStateHighlighted];
        enterBtn.size = enterBtn.currentBackgroundImage.size;
        enterBtn.centerX = shareBtn.centerX;
        enterBtn.centerY = imageView.height * 0.82;
        [imageView addSubview:enterBtn];
        
    }
    
    
    
    - (void)shareBtnClick:(UIButton *)btn {
    
        btn.selected = !btn.isSelected;
        
        DJLog(@"fdfd");
    
    }
