NSMutableArrayに書き込まない

Question

NSMutableArrayにパスを追加する必要があるアプリケーションとwriteToFileを持っています。

int r = arc4random() % 100; 
int s = arc4random() % 100; 
int e = arc4random() % 100; 
NSLog(@"%i%i%i.MOV", r, s, e); 
NSString * tempFileName = [NSString stringWithFormat:@"%i%i%i.MOV", r, s, e]; 
NSString * tempFilePath = [[info objectForKey:UIImagePickerControllerMediaURL] path]; 
NSString * documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; 
NSString * storePath = [documentsDirectory stringByAppendingPathComponent:tempFileName]; 
NSError *error = nil; 
[[NSFileManager defaultManager] copyItemAtURL:[NSURL fileURLWithPath:tempFilePath] 
             toURL:[NSURL fileURLWithPath:storePath] 
             error:&error]; 

if (error) { 
    NSLog(@"%@", error); 
} 
NSLog(@"Old File path : %@", tempFilePath); 
NSLog(@"New File path : %@", storePath); 
dayCounter ++; 
    videoDayCounter = [[NSMutableArray alloc] initWithContentsOfFile:dayCounterPath]; 
    NSLog(@"DayCounter INIT"); 
[videoDayCounter addObject:dayCounter]; 
[videoDayCounter writeToFile:dayCounterPath atomically:YES]; 
NSLog(@"dayCounter wrote to file"); ' 
allVideos = [[NSMutableArray alloc] initWithContentsOfFile:allVideosPath]; 
NSLog(@"AllVideosINIT"); 
[allVideos addObject:storePath]; 
NSLog(@"array: %@", allVideos); 
[allVideos writeToFile:allVideosPath atomically:YES]; 
[videoCount setText:[allVideos count]]; 
[daysLabel setText:[videoDayCounter count]]; 
[self dismissModalViewControllerAnimated:YES]; 
[picker release]; 

NSLog for allVideosがNULLを返しています。

私は

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *allVideosPath = [documentsDirectory stringByAppendingPathComponent:@"allVideos.plist"]; 
NSString *dayCounterPath = [documentsDirectory stringByAppendingPathComponent:@"dayCount.plist"]; 
BOOL booleanAllVideos; 
BOOL booleanDayCounter; 
NSFileManager *fileManager = [NSFileManager defaultManager]; 

booleanAllVideos = [fileManager fileExistsAtPath:allVideosPath]; 
booleanDayCounter= [fileManager fileExistsAtPath:dayCounterPath]; 

if(booleanAllVideos == NO) 
{ 
    NSMutableArray *allVideos = [[NSMutableArray alloc] initWithCapacity:3]; 
    [allVideos writeToFile:allVideosPath atomically:YES]; 
} 
if(booleanDayCounter == NO) 
{ 
    NSMutableArray *videoDayCounter = [[NSMutableArray alloc] initWithCapacity:3]; 
    [allVideos writeToFile:dayCounterPath atomically:YES]; 
} 

によってアプリの起動時にallVideosPathを作成しようとしました。しかし、私はそれが動作しないと思いますか？

ありがとうございました！

Answer 1

[[NSFileManager defaultManager] copyItemAtURL:[NSURL fileURLWithPath:tempFilePath] 
            toURL:[NSURL fileURLWithPath:storePath] 
            error:&error]; 

"tempFilePath"ファイルが存在していますか？

リーディング機能では、allVideosPathが正しく定義されていますか？私はあなたの読書機能でそれを設定するコードは見ません。
