How do you set the text in an NSTextField?
提问by Alexsander Akers
I'm trying to set the text in an NSTextField, but the -setStringValue:and -setTitleWithMnemonic:methods are not working. Any ideas?
我正在尝试在 NSTextField 中设置文本，但-setStringValue:和-setTitleWithMnemonic:方法不起作用。有任何想法吗？
回答by Ken Aspeslagh
setStringValue:is the way to do it. You should make sure your outlet is being set properly. (In the debugger, make sure your textfield variable is not null.)
setStringValue:是这样做的方法。您应该确保您的插座设置正确。（在调试器中，确保您的文本字段变量不为空。）

Just do something like this:
只是做这样的事情：
myLabel.stringValue = @"My Cool Text";

Just myLabel.stringValue = "MY TEXT"works here, using Swift and Xcode 6.
只是myLabel.stringValue = "MY TEXT"在这里工作，使用 Swift 和 Xcode 6。

self.yourTextField.stringValue = "Your_Value"
Note: Fetching value from self.yourTextField.stringValue at that will get warning message i.e.
To avoid this kind of warning you can use like this (suggested way)
注意：从 self.yourTextField.stringValue 中获取值会得到警告消息，即
为了避免这种警告，你可以像这样使用（建议的方式）
DispatchQueue.main.async {
your code ...
}
OR also refer to this.
或者也参考这个。

If the value you're trying to set happens to be an integer rather than a string, you don't need to convert the integer value to a string manually; you can just call:
如果您尝试设置的值恰好是整数而不是字符串，则无需手动将整数值转换为字符串；你可以打电话：
myLabel.integerValue = i;
The integerValueproperty is defined on NSTextField's parent class, NSControl. See that linked documentation page for a full list of methods it supports.
该integerValue属性是在NSTextField的父类上定义的NSControl。有关它支持的方法的完整列表，请参阅链接的文档页面。
