Hello, can upgrade an old front-end app for mac ventura 13.0? I have the complete source write in cocoa xCode e object C. When try to export app the system tell me Build fail. Have 5 error in syntax of CGColours component and conversion. The source in question is avaible for free at this link. https://mnt.conts.it/winxound/downloads/WinXound_3_4_0_OSX_Sources_XCode_4_5_0.zip Thank’s anyway.

Hi, I'm wondering if anyone else has seen this (and hopefully found a workaround). I'm working on a bug in PyObjC (https://github.com/ronaldoussoren/pyobjc/issues/17) related to protocols and can reproduce this in pure (Objective-)C. PyObjC creates a protocol and populates the method descriptors using the Objective-C runtime API, e.g. objc_allocateProtocol and protocol_getMethodDescription. This appears to work unreliably when adding multiple methods using protocol_getMethodDescription when the selector name and/or type encoding argument to protocol_getMethodDescription are not static strings: When the arguments are not static strings I have trouble finding the method descriptor using protocol_getMethodDescription. The code fails intermittently when adding two methods (but still fairly often), and fails reliably for me when adding 3 methods. The PyObjC issue I mentioned earlier contains a full reproducer.

Is it possible to differentiate whether user has no signal from carrier's mobile internet or purposefully has Airplane mode enabled? I want to disable some features inside my app if user has Airplane mode enable. At the same time, I want to keep these same features enabled if the device simply do not have service from carrier at that moment. platform :ios, '11.0' Following block code with Objective C was found in a StackOverFlow post and it is helpfull but it either lack of signal from carrier or airplane mode returns as ConnectionTypeNone. typedef enum { ConnectionTypeUnknown, ConnectionTypeNone, ConnectionType3G, ConnectionTypeWiFi } ConnectionType; + (ConnectionType)connectionType { SCNetworkReachabilityRef reachability = SCNetworkReachabilityCreateWithName(NULL, "8.8.8.8"); SCNetworkReachabilityFlags flags; BOOL success = SCNetworkReachabilityGetFlags(reachability, &flags); CFRelease(reachability); if (!success) { return ConnectionTypeUnknown; } BOOL isReachable = ((flags & kSCNetworkReachabilityFlagsReachable) != 0); BOOL needsConnection = ((flags & kSCNetworkReachabilityFlagsConnectionRequired) != 0); BOOL isNetworkReachable = (isReachable && !needsConnection); if (!isNetworkReachable) { return ConnectionTypeNone; } else if ((flags & kSCNetworkReachabilityFlagsIsWWAN) != 0) { return ConnectionType3G; } else { return ConnectionTypeWiFi; } }

I have an authentication app (authApp) that runs on Mac. AuthApp lets you log in to the Mac. It runs in place of the default login screen. I have added a new button in authApp and I want that button to launch another app (let's call it newApp) when clicked. AuthApp is written in Objective-C and newApp in Swift. I am able to launch newApp from the login screen every time at logout with the help of launchd agents. But that is not what I want; I want it to open only when the button in AuthApp is clicked. This is my launchd plist `<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>com.example.apple-sample</string> <key>LimitLoadToSessionType</key> <string>LoginWindow</string> <key>KeepAlive</key> <true/> <key>ProgramArguments</key> <array> <string>/Library/PrivilegedHelperTools/newApp.app/Contents/MacOS/newApp</string> </array> </dict> </plist>` The file is saved in /Library/LaunchAgents. newApp is in /Library/PrivilegedHelperTools. Is there a way to execute this launchd programmatically (Objective-C++/Swift) from the code so that newApp is launched? Please note this needs to be done before the user has logged in to the machine.

Consider the following Objective-C protocol declaration, which requires only class methods: @protocol TDWMethoding<NSObject> + (void)foo; + (void)bar; @end Assuming I need to return an instance of a Class which conforms to this protocol from a method, how am I supposed to specify the return type? - (nullable /*return-type*/)instantiateMethoding { Class instance = ... // some implementation if ([instance conformsToProtocol:@protocol(TDWMethoding)]) { return instance; } return nil; } There are a number of working options I considered so far in regards to how to express the /*return-type*/, but each has its own downsides: Class - this way it doesn't expose conformance. What kind of Class is it? What does it do? Does it conform to the protocol at all? Class<TDWMethoding> - this looks like a viable solution and even was suggested a few times by other developers (here and here) but I personally find it inconsistent and misleading: when we have a variable of form Type<Protocol> *instance, it commonly means that protocol class methods should be sent to the instance's class ([[instance class] foo]) not the instance itself ([instance foo]); id<TDWMethoding> and returning an instance of the class instead - this is consistent, but it requires me to instantiate the class, which is both redundant and prevents me from hiding the constructors of the utility classes which conforms to the protocol with NS_UNAVAILABLE macro. Is there a better semantic to express such a return-type?

I try to parse a vcf-file. I use CNContact for this. That works quite well, but with the phonenumbers i have a problem. With CNLabeledValue<CNPhoneNumber*>* I get the label (e. g. "home") and the phonenumber in the value. Excerpt from the vCard: TEL;TYPE=home:1234567890 But if the number is tagged with a "pref" i can't get this tag for the phonenumber. Excerpt from the vCard: TEL;TYPE=home,pref:0987654321 Is there anyway to find out, which numbers are the preferred numbers? I use following code: for (CNLabeledValue<CNPhoneNumber*>* number in cnContact.phoneNumbers) { NSString *label = number.label; NSString *number = ((CNPhoneNumber*)number).stringValue; //Do some work with label and number }

Hello to everyone, my iOS banking app has a WKWebView that shows a webpage from an external supplier. For security reasons the file Cookies.binarycookies generated by this webpage should not be present in the backup of the app. I've implemented this code but it doesn't work  if ([[NSFileManager defaultManager] fileExistsAtPath:filePath]) {     BOOL result = NO;     NSURL *url = [NSURL URLWithString:filePath];     result = [url setResourceValue:[NSNumber numberWithBool:YES] forKey:NSURLIsExcludedFromBackupKey error:&error]; } The result value is YES after the execution but the file is still present in the backup. I doubt that this file is protected and this fix won't work. Have you any suggestion on how I can proceed? Thank you, Chiara

I have an application in iOS that needs to be stream from a device and display on iPhone. Also the user needs to record the stream to phone storage when they tap a button. Added a pipeline in server side: gst-launch-1.0 -v avfvideosrc device-index=0 ! video/x-raw,framerate=20/1 ! videoscale ! videoconvert ! x264enc tune=zerolatency bitrate=500 speed-preset=superfast ! rtph264pay ! queue ! udpsink host=192.168.0.106 port=5005 also in client side: (GStreamerBackend.m) pipeline = gst_parse_launch("udpsrc port=5005 caps="application/x-rtp, media=video, clock-rate=90000, encoding-name=H264, tune=zerolatency, bitrate=500, speed-preset=superfast, payload=96" ! rtph264depay ! h264parse ! tee name=t t. ! queue ! avimux ! filesink location=/var/mobile/Containers/Data/Application/C40A7960-18CC-480E-9171-520ADF26BB8D/Documents/video1.avi t. ! queue leaky=1 ! decodebin ! videoconvert ! autovideosink sync=false", &error); This will display and record the stream correctly. But how do I separate the display and record? I need to record the stream only on button click. I need to add a new class for start and stop recording. I found the code in .c But need it in objective c. If anybody knows, please let me inform.

Hi, I made an app where you can share photos and videos, but I want to make it a thing so the user can share the photo or video through the photos app on your phone. Is it something apple does automatically or do I have to embed this fature in.

I assign its navigationDelegate in my 'CustomWebView' init function, the init function is called in the viewDidLoad function and the 'CustomWebView' implements the WKNavigationDelegate functions, objection_requires(NSStringFromSelector(@selector(configRepository))) - (instancetype)initWithConfiguration:(WKWebViewConfiguration *)configuration configRepository:(SKYConfigRepository *)configRepository { self = [super init]; _configRepository = configRepository; if (self) { [[JSObjection defaultInjector] injectDependencies:self]; self.converterLink = [JSObjection defaultInjector][@protocol(UniversalLinkConverterProtocol)]; WKWebViewConfiguration *wkWebViewConfig = [self getWebViewConfigWithUpdatedUserAgent:configuration]; _wkWebView = [[WKWebView alloc] initWithFrame:CGRectZero configuration:wkWebViewConfig]; _wkWebView.navigationDelegate = self; ... ... then when I debug the '_wkWebView.navigationDelegate' is nil the 'self' is not nil, and it implements the WKNavigationDelegate, {   WKWebView *_wkWebView;   SKYConfigRepository *_configRepository; }

I read the article here... https://developer.apple.com/documentation/swift/imported_c_and_objective-c_apis/importing_swift_into_objective-cand this is what I did.Created a header file for swift file.added @class SwiftFile.h#import MyAppTargetName-Swift.h in the objc file from where I want to reference my swift code.Now in my swift file when I write...@interface ClassName { MySwiftClass *swiftClass; }I get error message Unknown Type Name "MySwiftClass".How can I resolve this and get going?Am I doing something wrong?Does the bridging header i created along with the swift file need to me edited?Neerav

I need for an objc implementation exactly the functionality of this swift documentation: https://developer.apple.com/documentation/accelerate/vimage/pixelbuffer/3951652-cropped?changes=_7_1&language=objc It seems that there is no objc documentation present. Does anyone know how to call the crop function in objc?

So currently this is happening when I set my C language dialect to gnu11. Which one would I have to use for these errors to disappear?

How do I check the host macOS version in which Xcode or the Simulator is running? None of the TargetConditionals in TARGET_OS would work for this.

I'm looking for a way to set up a new alarm in the actual IOS Alarm Clock application from a new (self-created) app.Basically, the app I'm creating would programmatically add a new alarm to the Default alarm Clock app, which would then simply behave as it normally does -- making the built-in alarm clock ring when the time arrives.

I'm using the below code to activate Esim, UIBackgroundTaskIdentifier backgroundTaskIdentifier = [[UIApplication sharedApplication] beginBackgroundTaskWithExpirationHandler:^{}]; [plan addPlanWith:request completionHandler:^(CTCellularPlanProvisioningAddPlanResult result) { if (result==CTCellularPlanProvisioningAddPlanResultFail){ NSError *error = [NSError errorWithDomain:@"react.native.simcardsmanager.handler" code:1 userInfo:nil]; reject(@"2", @"CTCellularPlanProvisioningAddPlanResultFail - Can't add an Esim subscription", error); }else if (result==CTCellularPlanProvisioningAddPlanResultUnknown){ NSError *error = [NSError errorWithDomain:@"react.native.simcardsmanager.handler" code:1 userInfo:nil]; reject(@"3", @"CTCellularPlanProvisioningAddPlanResultUnknown - Can't setup eSim due to unknown error", error); }else{ //CTCellularPlanProvisioningAddPlanResultSuccess resolve(@(true)); } [[UIApplication sharedApplication] endBackgroundTask:backgroundTaskIdentifier]; }]; When I call the method, it will simultaneously open the "Add Cellular Plan" wizard and return the CTCellularPlanProvisioningAddPlanResultUnknown. However, in the end, the Esim will add successfully, but I will not receive the prosperous state in "completion handler."
