Retrieving data from a plist - plist

`Okay so I am trying to pull questions and possible answers from a plist file I have created
<key>Question1</key>
<string></string>
<key>Answer1</key>
<array/>
<key>4</key>
<string>A</string>
<key>2</key>
<string>B</string>
<key>3</key>
<string>C</string>
So I have tried to do this in code from looking a various tutorials, I am only new to this so I know I have it all wrong
so then I want to place the question in an label created in the storyboard and the same with the possible answers????
`
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *listPath = [[self docDir]stringByAppendingPathComponent:#"work.plist"];
if (![[NSFileManager defaultManager]fileExistsAtPath:listPath]) {
[[NSFileManager defaultManager] copyItemAtPath:[[NSBundle mainBundle]pathForResource:#"work" ofType:#"plist"]toPath:listPath error:nil];
}
NSMutableArray *array = [NSMutableArray arrayWithContentsOfFile:listPath];NSLog(#"count: %i", [array count]);
NSDictionary *temp = (NSDictionary *)[NSPropertyListSerialization
propertyListFromData:#"work.plist";
self.firstQuestion = [temp objectForKey:#"Question1"];
self.firstanswer = [NSMutableArray arrayWithArray:[temp objectForKey:#"Answer"]];`

TRY this too.
NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [path objectAtIndex:0];
NSString *plistpath = [documentsPath stringByAppendingPathComponent:#"question.plist"];
NSMutableArray *savedStock = [[NSMutableArray alloc] initWithContentsOfFile:plistFilePath];
for (int i=0; i<[savedStock count]; i++)
{
[A-array addObject:[[savedStock objectAtIndex:i] valueForKey:#"A"]];
[B-array addObject:[[savedStock objectAtIndex:i] valueForKey:#"B"]];

How to get a video PHAsset disk file size?

I'm trying to determine the file size on disk of a PHAsset video.
The following code is returning am error "The file “IMG_0188.mov” couldn’t be opened because you don’t have permission to view it."
PHVideoRequestOptions *options = [[PHVideoRequestOptions alloc] init];
options.version = PHVideoRequestOptionsVersionOriginal;
[[PHImageManager defaultManager] requestAVAssetForVideo:asset options:options resultHandler:^(AVAsset *avAsset, AVAudioMix *audioMix, NSDictionary *info) {
videoURL = [(AVURLAsset*)avAsset URL];
NSNumber *videoDiskFileSize;
NSError *error;
[videoURL getResourceValue:&videoDiskFileSize forKey:NSURLFileSizeKey error:&error];
if(error){
NSLog(#"ERROR %#", error.localizedDescription);
}
NSLog(#"size is %f",[videoDiskFileSize floatValue]/(1024.0*1024.0));
}];
Here's the correct way to do it.
PHVideoRequestOptions *options = [[PHVideoRequestOptions alloc] init];
options.version = PHVideoRequestOptionsVersionOriginal;
[[PHImageManager defaultManager] requestExportSessionForVideo:asset options:options exportPreset:AVAssetExportPresetHighestQuality resultHandler:^(AVAssetExportSession *exportSession, NSDictionary *info) {
CMTime videoDuration = CMTimeMultiplyByFloat64(exportSession.asset.duration, 1);
exportSession.timeRange = CMTimeRangeMake(kCMTimeZero, videoDuration);
NSLog(#"Byyte size = %lld", exportSession.estimatedOutputFileLength);
videoSize = exportSession.estimatedOutputFileLength;
}];

I think you have not added UITableviewDataSource and UITableViewDelegate in your .h file
Add UITableViewDataSource,UITableViewDelegate in interface (.h) file
#interface MSPackagesController : UIViewController <UITableViewDataSource,UITableViewDelegate>

GPUImageView Integration in my project

What I am trying to do is this.
- (void)viewDidLoad
{
[super viewDidLoad];
NSURL *url2 = [[NSBundle mainBundle] URLForResource:#"NAN" withExtension:#"mov"];
GPUImageMovie *movie2 = [[GPUImageMovie alloc] initWithURL:url2];
movie2.playAtActualSpeed = YES;
filter0 = [[GPUImageSepiaFilter alloc] init];
[movie2 addTarget:filter0];
[filter0 addTarget:view0]; // view0 is a GPUImageView taken in nib
[self recordVideo];
isRecording = YES;
[movie2 startProcessing];
[movieWriter setCompletionBlock:^{
if (isRecording) {
[self stopRecording];
isRecording = NO;
} }];
}
-(void)recordVideo {
NSString *path = [NSTemporaryDirectory() stringByAppendingPathComponent:#"file.mov"];
NSURL *url = [NSURL fileURLWithPath:path];
NSFileManager *fm = [NSFileManager defaultManager];
[fm removeItemAtPath:path error:nil];
movieWriter = [[GPUImageMovieWriter alloc] initWithMovieURL:url size:CGSizeMake(640, 480)];
[filter0 addTarget:movieWriter];
[movieWriter startRecording];
}
-(void)stopRecording {
[movieWriter finishRecording];
}
But this is not working at all. I always get a black video with this code. There is no crash, I get a black video with the same duration as of original video. Has anyone faced the same issue. Kindly help.
Any help would be great.

This gives you an example of how the search bar uses things around it and how it works
I Recently worked on something similar and this website should tell you everything wrong as well as give you an example of how it works

}
please help
thankzzzzz
What you described is much like a message borad with images, there is a twitter open source project tweetero: http://code.google.com/p/tweetero/ You can take a look at MessageListController and ImageLoader.
In generally, you could do like this:
1) Send async request to server to get message date(not images)
2) reload the table data, and send the image loader request for each uiimageview.
3) set the uiimageview when the image is loaded. A default loading image can be used until the real image is loaded.
