Android Toast equivalent in iOS
提问by Bil Kimes
Does anyone know what the Java Toastequivalent of this iOS Objective C event would be in a Fragment? Below is a sample of what I have written in iOS. What I am looking for the same Alert in Java using a Toast in place of the iOS UIAlert. I am sorry if I did not make that clear on my original post.
有谁知道这个 iOS Objective C 事件的Java Toast等价物在 Fragment 中是什么？下面是我在 iOS 中编写的示例。我正在使用 Toast 代替 iOS UIAlert 在 Java 中寻找相同的警报。如果我没有在我的原始帖子中说清楚，我很抱歉。
- (void) dateLogic {
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"MMMM dd"];
NSString *theDate = [dateFormat stringFromDate:[NSDate date]];
//JANUARY
if ([theDate isEqualToString:@"January 01"]) {
feastDay = [[UIAlertView alloc]
initWithTitle:@"New Years Day!"
message:@"January 01"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:@"Close", nil];
feastDay.delegate = self;
[feastDay show];
}
}

I found this amazing class in github that works like a charm. Toast for iOSIt is enough to import the UIView+Toast.h and UIView+Toast.m files and then add
我在 github 中发现了这个神奇的类，它的作用就像一个魅力。 Toast for iOS只需导入 UIView+Toast.h 和 UIView+Toast.m 文件，然后添加
[self.view makeToast:@"This is a piece of toast."];
as written in the page examples.
如页面示例中所述。

There is no android toast equivalent in iOS.
在 iOS 中没有 android toast 等价物。
But there are always workarounds like
但总有一些解决方法，比如
you can animate a view and play with its alpha
您可以为视图设置动画并使用其 alpha
The below is just sample code not a solution
以下只是示例代码，而不是解决方案
UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:3.0f];
imageView.alpha = 0.0f;
[UIView commitAnimations];
if you dont want to slowly fade within 3 seconds, you can use
如果你不想在 3 秒内慢慢淡出，你可以使用
[UIView setAnimationDelay:3];
and reduce the animation duraction to 0.5f or something. i think using a short fade out time feels better than just simply set hide to YES
并将动画持续时间减少到 0.5f 左右。我认为使用较短的淡出时间比简单地将隐藏设置为 YES 感觉更好

I handled it with a simple static UI Helper method using the Key Window:
我使用 Key Window 通过一个简单的静态 UI Helper 方法处理它：
+(void)displayToastWithMessage:(NSString *)toastMessage
{
[[NSOperationQueue mainQueue] addOperationWithBlock:^ {
UIWindow * keyWindow = [[UIApplication sharedApplication] keyWindow];
UILabel *toastView = [[UILabel alloc] init];
toastView.text = toastMessage;
toastView.font = [MYUIStyles getToastHeaderFont];
toastView.textColor = [MYUIStyles getToastTextColor];
toastView.backgroundColor = [[MYUIStyles getToastBackgroundColor] colorWithAlphaComponent:0.9];
toastView.textAlignment = NSTextAlignmentCenter;
toastView.frame = CGRectMake(0.0, 0.0, keyWindow.frame.size.width/2.0, 100.0);
toastView.layer.cornerRadius = 10;
toastView.layer.masksToBounds = YES;
toastView.center = keyWindow.center;
[keyWindow addSubview:toastView];
[UIView animateWithDuration: 3.0f
delay: 0.0
options: UIViewAnimationOptionCurveEaseOut
animations: ^{
toastView.alpha = 0.0;
}
completion: ^(BOOL finished) {
[toastView removeFromSuperview];
}
];
}];
}

We've implemented something like this in our open source library Raisin Toast. Setup is quite straightforward once you add the files to your project:
我们已经在我们的开源库Raisin Toast 中实现了类似的功能。将文件添加到项目后，设置非常简单：
Add a property to your app delegate:
向您的应用委托添加一个属性：
@property (strong, nonatomic) RZMessagingWindow *errorWindow;
Create the default messaging window:
创建默认消息窗口：
self.errorWindow = [RZMessagingWindow defaultMessagingWindow];
[RZErrorMessenger setDefaultMessagingWindow:self.errorWindow];
and then one line to present the messaging window:
然后一行显示消息窗口：
[RZErrorMessenger displayErrorWithTitle:@"Whoops!" detail:@"Something went horribly wrong and we accidentally cut off the wrong leg"];
The demo project highlights some of the more advanced customizations of adding images and custom styles.
演示项目重点介绍了添加图像和自定义样式的一些更高级的自定义。
The implementation uses a second UIWindow and because of the RZErrorMessenger class method it's available everywhere.
该实现使用了第二个 UIWindow，并且由于 RZErrorMessenger 类方法，它在任何地方都可用。

Maybe this can help someone:
也许这可以帮助某人：
NSString *message = @"Toast kind of message";
UIAlertView *toast = [[UIAlertView alloc] initWithTitle:nil
message:message
delegate:nil
cancelButtonTitle:nil
otherButtonTitles:nil, nil];
[toast show];
int duration = 1; // in seconds
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, duration * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
[toast dismissWithClickedButtonIndex:0 animated:YES];
});
UPDATEUIAlertView is deprecated in IOS 8. Here the new way:
更新UIAlertView 在 IOS 8 中已弃用。这里是新方法：
NSString *message = @"Toast kind of message";
UIAlertController *toast =[UIAlertController alertControllerWithTitle:nil
message:message
preferredStyle:UIAlertControllerStyleAlert];
[self presentViewController:toast animated:YES completion:nil];
int duration = 1; // in seconds
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, duration * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
[toast dismissViewControllerAnimated:YES completion:nil];
});
EDIT:For the ones that using Xamarin.IOS you can do like this:
编辑：对于那些使用 Xamarin.IOS 你可以这样做：
new UIAlertView(null, message, null, "OK", null).Show();
using UIKit; is required.
使用 UIKit；是必须的。

A Swift 3 solution ready for copy paste:
准备复制粘贴的 Swift 3 解决方案：
import UIKit
public extension UIView {
public func showToast(message:String, duration:Int = 2000) {
let toastLabel = UIPaddingLabel();
toastLabel.padding = 10;
toastLabel.translatesAutoresizingMaskIntoConstraints = false;
toastLabel.backgroundColor = UIColor.darkGray;
toastLabel.textColor = UIColor.white;
toastLabel.textAlignment = .center;
toastLabel.text = message;
toastLabel.numberOfLines = 0;
toastLabel.alpha = 0.9;
toastLabel.layer.cornerRadius = 20;
toastLabel.clipsToBounds = true;
self.addSubview(toastLabel);
self.addConstraint(NSLayoutConstraint(item:toastLabel, attribute:.left, relatedBy:.greaterThanOrEqual, toItem:self, attribute:.left, multiplier:1, constant:20));
self.addConstraint(NSLayoutConstraint(item:toastLabel, attribute:.right, relatedBy:.lessThanOrEqual, toItem:self, attribute:.right, multiplier:1, constant:-20));
self.addConstraint(NSLayoutConstraint(item:toastLabel, attribute:.bottom, relatedBy:.equal, toItem:self, attribute:.bottom, multiplier:1, constant:-20));
self.addConstraint(NSLayoutConstraint(item:toastLabel, attribute:.centerX, relatedBy:.equal, toItem:self, attribute:.centerX, multiplier:1, constant:0));
UIView.animate(withDuration:0.5, delay:Double(duration) / 1000.0, options:[], animations: {
toastLabel.alpha = 0.0;
}) { (Bool) in
toastLabel.removeFromSuperview();
}
}
}
The UIPaddingLabel class:
UIPaddingLabel 类：
import UIKit
@IBDesignable class UIPaddingLabel: UILabel {
private var _padding:CGFloat = 0.0;
public var padding:CGFloat {
get { return _padding; }
set {
_padding = newValue;
paddingTop = _padding;
paddingLeft = _padding;
paddingBottom = _padding;
paddingRight = _padding;
}
}
@IBInspectable var paddingTop:CGFloat = 0.0;
@IBInspectable var paddingLeft:CGFloat = 0.0;
@IBInspectable var paddingBottom:CGFloat = 0.0;
@IBInspectable var paddingRight:CGFloat = 0.0;
override func drawText(in rect: CGRect) {
let insets = UIEdgeInsets(top:paddingTop, left:paddingLeft, bottom:paddingBottom, right:paddingRight);
super.drawText(in: UIEdgeInsetsInsetRect(rect, insets));
}
override var intrinsicContentSize: CGSize {
get {
var intrinsicSuperViewContentSize = super.intrinsicContentSize;
intrinsicSuperViewContentSize.height += paddingTop + paddingBottom;
intrinsicSuperViewContentSize.width += paddingLeft + paddingRight;
return intrinsicSuperViewContentSize;
}
}
}

I know this question is pretty old, but I found myself here wondering the same thing, and I found a solution, so I thought I would share. This method allows for the alert to be dismissed after a time delay set by you.
我知道这个问题已经很老了，但我发现自己在这里想知道同样的事情，我找到了一个解决方案，所以我想我会分享。此方法允许在您设置的时间延迟后解除警报。
let alertController = UIAlertController(title: "Error", message: "There was a problem logging in, please try again", preferredStyle: UIAlertControllerStyle.alert)
self.present(alertController, animated: true, completion: nil)
let delay = DispatchTime.now() + 1 // change 1 to desired number of seconds
DispatchQueue.main.asyncAfter(deadline: delay) {
// Your code with delay
alertController.dismiss(animated: true, completion: nil)
}
If you get an error that crashes your app, it may be because the alertConroller is being run on a background thread. To fix this wrap your code in this:
如果您收到导致应用程序崩溃的错误，可能是因为 alertConroller 正在后台线程上运行。要解决此问题，请将您的代码包装在：
DispatchQueue.main.async(execute: {
});
This method allows the message to be dismiss when the user clicks an "OK" button below the message
当用户单击消息下方的“确定”按钮时，此方法允许关闭消息
let alertController = UIAlertController(title: "Error", message: "There was a problem logging in, please try again", preferredStyle: UIAlertControllerStyle.alert)
let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default) { (result : UIAlertAction) -> Void in
print("OK")
}
alertController.addAction(okAction)
self.present(alertController, animated: true, completion: nil)

Daniele D has an elegant solution, but UIAlertView is deprecated. Use UIAlertController instead:
Daniele D 有一个优雅的解决方案，但不推荐使用 UIAlertView。使用 UIAlertController 代替：
NSString *message = @"Toast message.";
UIAlertController *toast =[UIAlertController alertControllerWithTitle:nil message:message preferredStyle:UIAlertControllerStyleAlert];
[self presentViewController:toast animated:YES completion:nil];
int duration = 2; // in seconds
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, duration * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
[toast dismissViewControllerAnimated:YES completion:nil];
});
