I found simple one 

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

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

Code:

(void)cacheDirectory {

    NSString *tempPath = NSTemporaryDirectory();

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

Call the method from wherever you want.

This will return the tmp folder name, then in finder do (cmd-shift-G) and paste the response 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 clears only JPGs from the directory, so if you want to clear anything else then amend it.
