An easier way to watch for file system events.
The starting point of any use is CBHFileSystemWatcher. It is used to describe what kind of file system events you want to get and how/where you want to receive them. When an event matching the description occurs the callback is invoked and passed a CBHFileSystemEvent which describes where and what happened.
Watch the contents of a directory with a block:
// [...]
NSString *path = @"/path/to/directory/to/watch";
CBHFileSystemWatcherType type = CBHFileSystemWatcherType_default;
id someContext = nil;
CBHFileSystemWatcher *watcher = [CBHFileSystemWatcher watcherOfPath:path withType:type andBlock:^(CBHFileSystemEvent *event) {
// Do something with the event and someContext.
}];
// [...]Watch the contents of a directory with an observer:
// [...]
- (void)watchPath
{
NSString *path = @"/path/to/directory/to/watch";
CBHFileSystemWatcherType type = CBHFileSystemWatcherType_default;
SEL selector = @selector(_fileSystemEventOccurred:);
id someContext = nil;
_watcher = [CBHFileSystemWatcher watcherWithObserver:self andSelector:selector ofPath:path withType:type andObject:someContext];
}
- (void)_fileSystemEventOccurred:(CBHFileSystemEvent *)event
{
id context = [event object];
// Do something with the event.
}
