Macos – Get value from NSTextField

cocoamacosnstextfield

I have an NSTextField and I need to get the field's value into a variable. What's the appropriate method?

Best Solution

For an NSString you would use:

NSString *myString = [theTextField stringValue];

For an int you would use:

int myInt = [theTextField intValue];

There are many other methods for getting the value from a control. Have a look at the NSControl reference for more info, under the "Getting and Setting the Control’s Value" section.

Here's a list:

doubleValue
floatValue
intValue
integerValue
objectValue
stringValue
attributedStringValue

Git – How to Remove .DS_Store files from a Git repository

Remove existing files from the repository:

find . -name .DS_Store -print0 | xargs -0 git rm -f --ignore-unmatch

Add this line:

.DS_Store

to the file .gitignore, which can be found at the top level of your repository (or create the file if it isn't there already). You can do this easily with this command in the top directory:

echo .DS_Store >> .gitignore

Then commit the file to the repo:

git add .gitignore
git commit -m '.DS_Store banished!'

Important: This check should always be performed asynchronously. The majority of answers below are synchronous so be careful otherwise you'll freeze up your app.

Swift

Install via CocoaPods or Carthage: https://github.com/ashleymills/Reachability.swift

Test reachability via closures

let reachability = Reachability()!

reachability.whenReachable = { reachability in
    if reachability.connection == .wifi {
        print("Reachable via WiFi")
    } else {
        print("Reachable via Cellular")
    }
}

reachability.whenUnreachable = { _ in
    print("Not reachable")
}

do {
    try reachability.startNotifier()
} catch {
    print("Unable to start notifier")
}

Objective-C

Add SystemConfiguration framework to the project but don't worry about including it anywhere
Add Tony Million's version of Reachability.h and Reachability.m to the project (found here: https://github.com/tonymillion/Reachability)

Update the interface section

#import "Reachability.h"

// Add this to the interface in the .m file of your view controller
@interface MyViewController ()
{
    Reachability *internetReachableFoo;
}
@end

Then implement this method in the .m file of your view controller which you can call

// Checks if we have an internet connection or not
- (void)testInternetConnection
{
    internetReachableFoo = [Reachability reachabilityWithHostname:@"www.google.com"];

    // Internet is reachable
    internetReachableFoo.reachableBlock = ^(Reachability*reach)
    {
        // Update the UI on the main thread
        dispatch_async(dispatch_get_main_queue(), ^{
            NSLog(@"Yayyy, we have the interwebs!");
        });
    };

    // Internet is not reachable
    internetReachableFoo.unreachableBlock = ^(Reachability*reach)
    {
        // Update the UI on the main thread
        dispatch_async(dispatch_get_main_queue(), ^{
            NSLog(@"Someone broke the internet :(");
        });
    };

    [internetReachableFoo startNotifier];
}

Important Note: The Reachability class is one of the most used classes in projects so you might run into naming conflicts with other projects. If this happens, you'll have to rename one of the pairs of Reachability.h and Reachability.m files to something else to resolve the issue.

Note: The domain you use doesn't matter. It's just testing for a gateway to any domain.
