Can anyone recommend a library for implementing growl or toast-style notifications on iOS? For example, after a user saves a profile, I wan开发者_C百科t to have a notification fade in, linger for 3 seconds, report "profile saved", and fade out. Right now I have a UIAlertView that interrupts the user's workflow with a single "OK" button, and I feel like that is overkill.
The Android Toast class is an example of what I am looking for on iOS.
Thanks!
I created a solution that I think you'll find useful: https://github.com/scalessec/toast
It's written as a obj-c category, essentially adding makeToast methods to any instance of UIView. eg:
[self.view makeToast:@"Profile saved"
duration:2.0
position:@"bottom"];
I solved it this way:
- Create common label on your view. Make it all screen wide, give it the size you will need and center text in it.
- Set it's position "on top" - this label must be below all of your controls in the list of controls.
- Add it to interface, properties, synthesize (let's call it "toastLabel" there).
- Associate in your XIB file with "toastLabel"
Add following line to your viewWillAppear to hide label for beginning:
[toastLabel setHidden:TRUE];Add the following code on Button click (or some other event):
toastLabel.text = @"Our toast text"; [toastLabel setHidden:TRUE]; [toastLabel setAlpha:1.0]; CGPoint location; location.x = 160; location.y = 220; toastLabel.center = location; location.x = 160; location.y = 320; [toastLabel setHidden:FALSE]; [UIView animateWithDuration:0.9 animations:^{ toastLabel.alpha = 0.0; toastLabel.center = location; }];
This label will "fall down" and disappear.
Albeit a little late, here's my take on it:
https://github.com/pcperini/PCToastMessage
You could try my open source library TSMessages: https://github.com/toursprung/TSMessages
It's really easy to use and looks beautiful on iOS 5/6 and on iOS 7 as well.
I made my own. The class linked to by Krishnan was ugly and didn't rotate correctly.
https://github.com/esilverberg/ios-toast
Here's what it looks like:
I made it in this way :
+ (void)showToastMessage:(NSString *)message {
UIAlertView *toast = [[UIAlertView alloc] initWithTitle:nil
message:message
delegate:nil
cancelButtonTitle:nil
otherButtonTitles:nil, nil];
[toast show];
// duration in seconds
int duration = 2;
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, duration * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
[toast dismissWithClickedButtonIndex:0 animated:YES];
});
}
Updated solution for iOS9+:
+ (void)showToastMessage:(NSString *)message
root:(id)view {
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:nil
message:message
preferredStyle:UIAlertControllerStyleAlert];
// duration in seconds
int duration = 2;
[view presentViewController:alertController animated:YES completion:nil];
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, duration * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
[alertController dismissViewControllerAnimated:YES completion:nil];
});
}
MBProgressHUD?
Hey you are looking for this.

This one is exactly what you want. This one is quite handy as well since it has a completion block, please have a look :) https://github.com/PrajeetShrestha/EkToast
Swift 2.0:
The idea is to work out a Toast class with zero dependency on CocoaPods.
Reference: https://github.com/scalessec/Toast-Swift
Make an empty Swift file (file-New-File- Empty Swift File - Name it Toast.)
Add the following code to it.
// Toast.swift
import UIKit
import ObjectiveC
enum ToastPosition {
case Top
case Center
case Bottom
}
extension UIView {
private struct ToastKeys {
static var Timer = "CSToastTimerKey"
static var Duration = "CSToastDurationKey"
static var Position = "CSToastPositionKey"
static var Completion = "CSToastCompletionKey"
static var ActiveToast = "CSToastActiveToastKey"
static var ActivityView = "CSToastActivityViewKey"
static var Queue = "CSToastQueueKey"
}
private class ToastCompletionWrapper {
var completion: ((Bool) -> Void)?
init(_ completion: ((Bool) -> Void)?) {
self.completion = completion
}
}

You can download a sample project from https://github.com/alvinreuben/ToastSample
This is something, which was needed by you. Created with lot of Animation Options, screen positions, and duration. Even you can provide your own duration. Check that out below.

Swift 3
Have been using Rannie/Toast-Swift for Swift 3 very happily for a while now and can recommend it for a very similar "Android-like" experience. Its very simple to implement without needing another pod and pretty customizable depending on your needs.
Easy Peasy
