直接运行swift demo报错，因为没有设置textView的字体样式，崩溃日志如下，还有，键盘输入时，最大行数限制有效，选择键盘上的候选文本，行数限制无效

Xcode版本: 11.3
编译swift demo，修改如图代码，运行闪退

崩溃位置

建议该方法做以下调整：

朋友，你在11.3运行这个font是空的？textview应该会有默认的字体的，如果这里崩溃，那所有的self.font都是有问题的。我升级11.3看下 | | zhangyuluios | | 邮箱：zhangyuluios@163.com | Signature is customized by Netease Mail Master 在2019年12月19日 16:40，jkwf 写道： Xcode版本: 11.3 编译swift demo，修改如图代码，运行闪退 崩溃位置 建议该方法做以下调整： — You are receiving this because you commented.

对，获取的font是nil， 模拟器版本是13.3

很奇怪。等我升级看下。你这个代码不是新的，你先更新代码。 | | zhangyuluios | | 邮箱：zhangyuluios@163.com | Signature is customized by Netease Mail Master 在2019年12月19日 17:05，jkwf 写道： 对，获取的font是nil， 模拟器版本是13.3 — You are receiving this because you commented. Reply to this email directly, view it on GitHub, or unsubscribe.

更新最新的也是有问题，建议增加默认font，还有发现一个问题
override func viewDidLoad() { super.viewDidLoad() view.backgroundColor = .lightGray let textview = UITextView(frame: CGRect(x: 100, y: 100, width: 200, height: 20)) textview.placeholder = "喜欢请Star" textview.limitLines = 4; textview.autoHeight = true textview.center = self.view.center view.addSubview(textview) }
这样写，选择输入中文，第一次输入中文确定后，就输不了中文，不加这一句代码《textview.placeholder = "喜欢请Star"》会闪退

应该是11.3的问题。以前没有发现过。新的xcode我还没下载。 | | zhangyuluios | | 邮箱：zhangyuluios@163.com | Signature is customized by Netease Mail Master 在2019年12月19日 17:24，jkwf 写道： 更新最新的也是有问题，建议增加默认font，还有发现一个问题 override func viewDidLoad() { super.viewDidLoad() view.backgroundColor = .lightGray let textview = UITextView(frame: CGRect(x: 100, y: 100, width: 200, height: 20)) textview.placeholder = "喜欢请Star" textview.limitLines = 4; textview.autoHeight = true textview.center = self.view.center view.addSubview(textview) } 这样写，选择输入中文，第一次输入中文确定后，就输不了中文，不加这一句代码《textview.placeholder = "喜欢请Star"》会闪退 — You are receiving this because you commented.

嗯，你更新一下最新版的看一下
