How do you set the text in an NSTextField?

问题

I'm trying to set the text in an NSTextField, but the -setStringValue: and -setTitleWithMnemonic: methods are not working. Any ideas?

回答1:

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.)

回答2:

Just do something like this:

myLabel.stringValue = @"My Cool Text";

回答3:

Just myLabel.stringValue = "MY TEXT" works here, using Swift and Xcode 6.

回答4:

Swift 4

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)

DispatchQueue.main.async {
 your code ... 
} 

OR also refer to this.

回答5:

ObjectiveC:

[label setStringValue: @"I am a label"];

original code I use in my code to display application version is:

    [lblVersion setStringValue:[NSString stringWithFormat:@"v%@", [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"]]];

回答6:

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:

myLabel.integerValue = i;

The integerValue property is defined on NSTextField's parent class, NSControl. See that linked documentation page for a full list of methods it supports.

just do this

[textField setString:@"random"];
