does anybody see what's wrong with this code?
UIImagePickerControllerSourceType pickerType = UIImagePickerControllerSourceTypePhotoLibrary;
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
[imagePicker setSourceType:pickerType];
[imagePicker setMediaTypes:[UIImagePickerController availableMediaTypesForSourceType:pickerType]];
[imagePicker setDelegate:self];
UIPopoverController *pop = [[UIPopoverController alloc] initWithContentViewController:imagePicker];
[pop setDelegate:self];
[pop presentPopoverFromRect:CGRectMake(100, 100, 100, 100) inView:self permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
[pop setPopoverContentSize:CGSizeMake(300, 500)];
On ios4 it works well. But on ios5/ipad it crashes with
*** Assertion failure in -[PLHighlightingTableView _createPreparedCellForGlobalRow:withIndexPath:], /SourceCache/UIKit_Sim/UIKit-1912.3/UITableView.m:6072
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:'
The exception occurs when I scroll the image picker.
Any ideas?

After some changes with help from #Frank van Puffelen
I getting a new error see below updated code and updated error
Hello everyone im trying to save a gif which I create with flutter_ffmpeg: ^0.4.2
With this code im trying to create a gif of picked video from user which is currently widget.videopathasstring
THis is the path of picked video.
Directory gifDirectory;
String gifOutputFile;
getpreviewvideo() async {
String currentvideo = widget.videopathasstring;
await getApplicationDocumentsDirectory().then((directory) {
print("13");
gifDirectory = Directory(directory.path + '/gif');
print("14");
gifDirectory.exists().then((exists) async {
print("0");
if (!exists) {
print("1");
await gifDirectory.create();
}
}).then((value) => {
print("3"),
gifOutputFile = gifDirectory.path +
'/' +
DateTime.now().millisecondsSinceEpoch.toString() +
'.gif',
});
});
print("4");
var arguments = [
'-i',
currentvideo,
'-t',
'2.5',
'-ss',
'2.0',
'-f',
'gif',
gifOutputFile,
];
_flutterFFmpeg.executeWithArguments(arguments).then((rc) {
print("FFmpeg process exited with rc $rc");
});
return File(gifOutputFile);
}
The problem is im getting this error

It seems you're not uploading the file to Cloud Storage, which only happens once you call putFile.
Have a look at the FlutterFire documentation on uploading files for an example of how to use putFile
I just switched to xcode 6 and ios8, I was trying to fix some warnings. The warnings were about some deprecated methods. So I changed the code in AppDelegate.h for push notifications to work with iOS 8 but I get errors
old code(xcode 5, iOS7)
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
New Code for iOS8
[[UIApplication sharedApplication] registerForRemoteNotifications:
(UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
How Can resolve this error?
Read the documentation. This is not how you use registerForRemoteNotifications. You call registerUserNotificationSettings: with the appropriate settings, and finally call [[UIApplication sharedApplication] registerForRemoteNotifications]; to register.
here is what we have done:
we added the framework to our project and
have the following in one of our classes:
GCSearchViewController.h
#interface GCSearchViewController : UIViewController<UISearchBarDelegate, GNSearchResultReady, GNAudioSourceDelegate>
GCSearchViewController.m
// - As per the web tutorial
#import <GracenoteMusicID/GNConfig.h>
#import <GracenoteMusicID/GNOperations.h>
#import <GracenoteMusicID/GNSearchResponse.h>
#import <GracenoteMusicID/GNSearchResult.h>
// - As per what we saw in the demo app
#import <GracenoteMusicID/GNRecognizeStream.h>
#import <GracenoteMusicID/GNAudioConfig.h>
#import <GracenoteMusicID/GNAudioSourceMic.h>
#import <AVFoundation/AVAudioSession.h>
…
#pragma mark - Gracenote Delegate
-(void) identifySong {
[[AVAudioSession sharedInstance] requestRecordPermission:^(BOOL response){
NSLog(#"Allow microphone use response: %d", response);
if (response) {
[GNOperations recognizeMIDStreamFromMic:self config:self.config];
}
}];
}
- (void) GNResultReady:(GNSearchResult *) result
{
GNSearchResponse *best = [result bestResponse];
if (![result isFailure] && (best.artist!=nil)) {
NSLog(#"Artist %#", best.artist);
NSLog(#"Song name %#", best.trackTitle);
} else {
NSLog(#"No Match");
}
}
- (void) audioBufferDidBecomeReady:(GNAudioSource*)audioSource samples:(NSData*)samples {
NSError *err;
err = [self.recognizeFromPCM writeBytes:samples];
if (err) {
NSLog(#"ERROR: %#",[err localizedDescription]);
}
}
this code works ok in the simulator, but whenever we run it on the device (ipod touch 5th or iphone 5) the app breaks with the following error:

our app is targeting iOS7... appreciate any pointers on how to make it work
This is an error with acquiring the Microphone hardware. The error log:
2013-11-16 22:00:40.402 GC[1758:60b] 22:00:40.401 ERROR: [0x3c29f18c] >aurioc> 783: failed: -10851 (enable 1, outf< 2 ch, 0 Hz, Float32, non-inter> inf< 1 ch, 44100 Hz, Int16>)
Above error happens in two cases:
Microphone Hardware was not configured correctly OR
RemoteIO was unable to acquire hardware.
This is typically happens with Simulator but can happen on the device if the microphone is inaccessible. The error can also happen if AVAudioSession is not correctly configured or is messed up. Check AVAudioSession configuration and Try deleting the iOS app, re-installing it and doing a clean build.
Before updating my Xcode from 4.1 to 4.2 the following was code was working fine with iOS 4.3, but after upgrading Xcode and test my app on iPhone with iOS 5 it keep crashing on startup!
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[self.window addSubview:tabController.view];
[[tabController.tabBar.items objectAtIndex:0] setTitle:#"Tab1"];
[[tabController.tabBar.items objectAtIndex:1] setTitle:#"Tab2"];
[[tabController.tabBar.items objectAtIndex:2] setTitle:#"Tab3"];
[[tabController.tabBar.items objectAtIndex:3] setTitle:#"Tab4"];
[[tabController.tabBar.items objectAtIndex:4] setTitle:#"Tab5"];
[[tabController.tabBar.items objectAtIndex:5] setTitle:#"Tab6"];
[[tabController.tabBar.items objectAtIndex:6] setTitle:#"Tab7"];
[[tabController.tabBar.items objectAtIndex:7] setTitle:#"Tab8"];
[[tabController.tabBar.items objectAtIndex:8] setTitle:#"Tab9"];
[self.window makeKeyAndVisible];
return YES;
}
It throws the following error:
2011-10-15 15:13:31.238 Mobile[2347:707] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayI objectAtIndex:]: index 5 beyond bounds [0 .. 4]'

If I kept only the first 5 setTitle it will work, but if its more than 5 it will crash!
Please note that I'm creating the UITabBarController in IB not programatically.
Try accessing the viewControllers array on the tabController instead and editing the tabItem on the View Controller directly.
[[tabController.viewControllers objectAtIndex:0].tabBarItem setTitle:#"Tab1"];
I want to monitor a virtual COM port (Arduino RFID) on my Mac. I can run "screen /dev/tty.serialnumber" from the terminal, and it outputs the RFID serial number when I swipe it.
As soon as I try it from Xcode with an NSTask I get the following output.
Must be connected to a terminal.
Here's my code:
NSTask *cd = [[NSTask alloc] init];
[cd setLaunchPath:#"/usr/bin/screen"];
[cd setArguments:[NSArray arrayWithObjects:#"-L",#"/dev/tty.usbserial-A800509K",nil]];
NSPipe *pipe;
pipe = [NSPipe pipe];
[cd setStandardOutput: pipe];
[cd setStandardInput:[NSPipe pipe]];
NSFileHandle *file;
file = [pipe fileHandleForReading];
[cd launch];
NSData *data;
data = [file readDataToEndOfFile];
NSString *string;
string = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];
NSLog (#"%#", string);
[cd waitUntilExit];
[cd release];
I think you'd better directly access the COM port, either by using the foundation libraries, or by using third party Obj-C libs (for example, https://github.com/pbosetti/PBSerialPort).
Also, if you want to monitor the COM port, you will have to set a thread reading the serial port, and updating a text area in the UI. Remember that secondary thread should update the UI via the method - (void)performSelector:(SEL)aSelector onThread:(NSThread *)thr withObject:(id)arg waitUntilDone:(BOOL)wait.
