How to delete files from fron iOS temp directory?

I used the code to delete temp directory files while using the device.

-(void) clearAllTempFiles {
    NSString *path = NSTemporaryDirectory();
    if ([path length] > 0)
    {
        NSError *error = nil;  
        NSFileManager *fileManager = [NSFileManager defaultManager];

        BOOL deleted = [fileManager removeItemAtPath:path error:&error];

        if (deleted != YES || error != nil)
        {

        }
        else{
            // Recreate the Documents directory
            [fileManager createDirectoryAtPath:path withIntermediateDirectories:NO attributes:nil error:&error];
        }

    }
}

is it not working fine? is this the correct code to delete files from temp directory?

Help me?

You can get the name of the tmp directory on your mac using this in your code:

code:

(void)cacheDirectory {

    NSString *tempPath = NSTemporaryDirectory();

    NSLog(@"Temp Value = %@", items);
}

Call the method from anywhere.

This will return the name of the tmp folder, then in finder do (cmd-shift-G) and paste the answer you got from the console window.



The following will clear the TMP directory used by the simulator.

code:

NSString *tempPath = NSTemporaryDirectory();
NSArray *dirContents = [[NSFileManager defaultManager] directoryContentsAtPath:tempPath];
NSArray *onlyJPGs = [dirContents filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"self ENDSWITH '.jpg'"]];

NSFileManager *fileManager = [NSFileManager defaultManager];

if (onlyJPGs) { 
    for (int i = 0; i < [onlyJPGs count]; i++) {
    NSLog(@"Directory Count: %i", [onlyJPGs count]);
    NSString *contentsOnly = [NSString stringWithFormat:@"%@%@", tempPath, [onlyJPGs objectAtIndex:i]];
    [fileManager removeItemAtPath:contentsOnly error:nil];
}

The above code only clears the JPG from the directory, so if you want to remove anything else change it.

I found simple



NSArray* tmpDirectory = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:NSTemporaryDirectory() error:NULL];
for (NSString *file in tmpDirectory) {
    [[NSFileManager defaultManager] removeItemAtPath:[NSString stringWithFormat:@"%@%@", NSTemporaryDirectory(), file] error:NULL];
}
