SJNotificationViewController lets you put dead-simple notifications that slide up from the bottom or down from the top of a view into your iOS apps.
All you need to do is create a notification, give it a view to slide up from, and tell it to show itself. Like this:
SJNotificationViewController *notificationController = [[SJNotificationViewController alloc] initWithNibName:@"SJNotificationViewController" bundle:nil]; [notificationController setParentView:aView]; [notificationController setNotificationTitle:@"Hello"]; [notificationController show];
That gives you a basic notification that slides up from the bottom of
aView. When you want your notification to slide back down, you just call
[notificationController hide]. Pretty simple, right?
You can customise a few things about SJNotificationViewController:
SJNotificationViewController has a property called
notificationLevel that changes the notification's background colour. A notification's
notificationLevel is one of
SJNotificationLevelError (red -- for error notifications),
SJNotificationLevelMessage (blue -- for regular notifications), or
SJNotificationLevelSuccess (green -- for success notifications). The exact RGB values for the notification levels aren't set in stone yet. Right now, they're extremely red, extremely blue, and extremely green.
There is also a property called
notificationPosition to control whether your notification should appear at the top or at the bottom of its parent view. Set it to
SJNotificationPositionBottom (default) accordingly.
By default, a notification stays on screen until you tap it. To automatically hide it after a given delay, just set the property
notificationDuration. There are a few predefined values for it:
SJNotificationDurationStay, which is the default, keeps the notification on screen until the user taps it.
SJNofificationDurationShortsets it to 1.5 seconds,
SJNotificationDurationMediumsets it to 3 seconds,
SJNotificationDurationLongsets it to 5 seconds
- and finally,
SJNotificationDurationAlmostForeversets it to 10 seconds.
Instead of giving these typedef'd values, you can also just give the amount of milliseconds as an integer. Examples:
Background and Text Color
You can set the background color as well as text color like this:
[notificationController setBackgroundColor:[UIColor brownColor]];and
[notificationController setTextColor:[UIColor yellowColor]];
Tapping on a Notification
By default, tapping on a notification just hides it, but you can define your own target/selector pair to be called when the notification is tapped with
[notificationController setTapTarget:self action:@selector(doSomething)].
By default, a notification doesn't have a spinner, but you can give it one by calling
[notificationController setShowSpinner:YES]. Doing so will shrink the notification's label to fit the spinner.
More In-Depth Customisations
If you want to get into the .m file, you can change the colours that correspond to the different notification levels, the durations of the various animations, and the opacity of the notification's background.
