在最后一个欢迎界面上添加一个CheckBox.
// 2.添加4个UIImageView
for (int i = ; i < NEW_FEATURE_NUMS; i++) {
UIImageView *imageView = [[UIImageView alloc] init];
imageView.size = scrollView.size;
imageView.y = ;
imageView.x = i * scrollW;
NSString *imageName = [NSString stringWithFormat:@"new_feature_%d",i+];
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 - ) {
[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:];
shareBtn.titleEdgeInsets = UIEdgeInsetsMake(, , , );
shareBtn.width = ;
shareBtn.height = ;
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"); }
最终效果：
