iOS开发之复制字符串到剪贴板

这次需求有复制功能,把字符串复制到系统剪贴板,

1.在 View 里贴上scrollView
2.在scrollView里贴上 UITextView,用于上下滑动展示完整数据

    // 邀请链接
    UIView *linkView2 = [[UIView alloc] init];
    linkView2.backgroundColor = [UIColor whiteColor];
    linkView2.frame = CGRectMake(0, CGRectGetMaxY(line.frame), UI_View_Width, cellH);
    [self.view addSubview:linkView2];
    // 邀请链接label
    UILabel *linkLabel2 = [[UILabel alloc] init];
    linkLabel2.backgroundColor = [UIColor clearColor];
    linkLabel2.frame = CGRectMake(marginX, -1, 60, cellH);
    linkLabel2.text = @"邀请链接";
    linkLabel2.font = setupTextLabelFont;
    linkLabel2.textColor = XHHColor(102, 102, 102);
    [linkView2 addSubview:linkLabel2];
    // 复制按钮
    UIButton *copyBtn = [UIButton buttonWithType:UIButtonTypeCustom];
    [copyBtn setTitle:@"复制" forState:UIControlStateNormal];
    copyBtn.frame = CGRectMake(UI_View_Width - marginX - btnW, (cellH - btnH) * 0.5, btnW, btnH);
    copyBtn.titleLabel.font = [UIFont systemFontOfSize:12];
    [copyBtn addTarget:self action :@selector(copylinkBtnClick) forControlEvents:UIControlEventTouchUpInside];
    copyBtn.backgroundColor = [UIColor whiteColor];
    [copyBtn setTitleColor:XHHTitleColor forState:UIControlStateNormal];
    copyBtn.layer.borderColor = XHHTitleColor.CGColor;
    copyBtn.layer.cornerRadius = XHH_btnCornerRadius;
    copyBtn.layer.borderWidth = 1.0f;
    [linkView2 addSubview:copyBtn];
    self.copylinkBtn = copyBtn;

    // 滑动邀请链接
    UIScrollView *scrollView = [[UIScrollView alloc]initWithFrame:CGRectMake(CGRectGetMaxX(linkLabel2.frame), 0, UI_View_Width - linkLabel2.width - btnW - marginX * 2, cellH)];
    scrollView.showsHorizontalScrollIndicator = NO;
    scrollView.showsHorizontalScrollIndicator = NO;
    scrollView.bounces = NO;
    [linkView2 addSubview:scrollView];
    
    UITextView *link = [[UITextView alloc]initWithFrame:CGRectMake(0, 0, UI_View_Width - linkLabel2.width - btnW - marginX * 2, 50)];
    link.text = @"wwww.ujfwegertkyluiopafsdfghnlrjkliop[sdfghjklertyui";
    link.textColor = [UIColor grayColor];
    link.textContainer.maximumNumberOfLines = 1;
    link.scrollEnabled = YES;//是否可以拖动
    link.editable = NO;//禁止编辑
    [scrollView addSubview:link];
    scrollView.contentSize = CGSizeMake(CGRectGetWidth(link.bounds), 50);
    self.link = link;

/**
 * 复制链接
 */
- (void)copylinkBtnClick {
    
    [MBProgressHUD showSuccess:@"复制成功!"];
    UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
    pasteboard.string = self.link.text;
}
