我可以在siumulator上测试它吗？似乎没有为我工作。我在我的控制器的viewDidLoad方法中创建了一个toast。 – 2011-02-22 14:42:09

它在模拟器上工作。你可以通过示例代码吗？ – clide313 2011-02-22 19:29:48

这真的很不错，但是LGPL授权，所以你不能在iPhone应用程序中使用它，而不会使你的所有源代码都在LGPL之下。它与iPhone平时不同的原因是iPhone使用静态库.. – 2011-03-15 18:59:14

你在找什么类似UIAlertView？

不，这需要一个计时器来显示和隐藏。更简单一些，也许是开源社区的一个罐头类。敬酒内部照顾更多的管道。 – 2010-11-19 01:27:37

为什么不创建一个包装警报视图和计时器的类？也许你可以开源，从而解决你的问题和其他人的问题。 – Jasarien 2010-11-19 01:32:54

Jasarien是对的，你想解决的问题很简单，也很有用，敬酒摇滚。这对社区会有很大的帮助。 – blindstuff 2010-11-19 01:55:59

你可能会在本地通知之后，很确定他们允许你设置一个时间，我想在时间被解雇了。不要认为有办法隐藏它们。虽然我不熟悉吐司，但我可能会误解你的问题。

MonoTouch吐司版本在这里。受Android的启发。

称呼它，

 ToastView t = new ToastView ("Email Sent", 1000); 
     t.Show();

枚举文件：

public enum ToastGravity 
{ 
    Top = 0, 
    Bottom = 1, 
    Center = 2 
}

ToastSettings文件：

using System; 
using System.Drawing; 
using MonoTouch.UIKit; 
namespace General 
{ 

    public class ToastSettings 
    { 
     public ToastSettings() 
     { 
      this.Duration = 500; 
      this.Gravity = ToastGravity.Center; 
     } 

     public int Duration 
     { 
      get; 
      set; 
     } 

     public double DurationSeconds 
     { 
      get { return (double) Duration/1000 ;} 

     } 

     public ToastGravity Gravity 
     { 
      get; 
      set; 
     } 

     public PointF Position 
     { 
      get; 
      set; 
     } 


    } 
}

主要吐司类：

      UIWindow window = UIApplication.SharedApplication.Windows[0];

       point = new PointF (window.Frame.Size.Width/2, window.Frame.Size.Height - 45); 
      } 
      else if (theSettings.Gravity == ToastGravity.Center) 
      { 
       point = new PointF (window.Frame.Size.Width/2, window.Frame.Size.Height/2);

我在github上创建了一个新的回购库，提供一个类来执行iOS吐司式警报。我不喜欢code.google.com上的那个，它没有正确旋转并且不漂亮。

这里是我的版本：http://github.com/scalessec/toast

我认为这是简单的使用，因为它实现为OBJ-C类，从而增加了makeToast方法的UIView的任何实例。例如：

[self.view makeToast:@"This is some message as toast." 
      duration:3.0 
      position:@"bottom"];

有没有办法禁用父视图，以便用户不能点击远离活动吐司？我需要用户停止与应用程序交互，同时显示活动面包。（只有活动吐司，其余不需要这种行为。） – jkcl 2012-12-12 12:40:47

你可以使用这个链接，Objective-C代码的吐司

http://code.google.com/p/toast-notifications-ios/source/browse/trunk/

虽然这个链接，其使用

http://code.google.com/p/toast-notifications-ios/wiki/HowToUse

这可能是像任何以下示例之一

[[iToast makeText:NSLocalizedString(@"The activity has been successfully saved.", @"")] show]; 

[[[iToast makeText:NSLocalizedString(@"The activity has been successfully saved.", @"")] 
          setGravity:iToastGravityBottom] show]; 

[[[[iToast makeText:NSLocalizedString(@"Something to display a very long time", @"")] 
        etGravity:iToastGravityBottom] setDuration:iToastDurationLong] show];

你可以试试我的开源库TSMessages：https://github.com/toursprung/TSMessages

这真的很容易使用，外观漂亮iOS上5/6和iOS 7为好。

只要你可以使用下面的代码与uilabel和uianimation得到像在android中的烤面包。它做两件作品之一是烤面包的任务，它增加了标签的高度根据与换行IOS 7文本长度后link here

CGRect initialFrame = CGRectMake(20, self.view.frame.size.height/2,300, 40); 


NSString *[email protected]"Toast in Iphone as in Android"; 
UILabel *flashLabel=[[UILabel alloc] initWithFrame:initialFrame]; 
flashLabel.font=[UIFont fontWithName:@"Optima-Italic" size:12.0]; 
flashLabel.backgroundColor=[UIColor whiteColor]; 
flashLabel.layer.cornerRadius=3.0f; 
flashLabel.numberOfLines=0;

CGSize maxSize = CGSizeMake(flashLabel.frame.size.width, MAXFLOAT); 

CGRect labelRect = [message boundingRectWithSize:maxSize options:NSStringDrawingUsesLineFragmentOrigin attributes:@{NSFontAttributeName:flashLabel.font} context:nil]; 

//adjust the label the the new height.

我修改了约翰的回答如下：

@interface Toast : NSObject 

+ (void)toast:(NSString *)message 
      :(UIView *) view 
      :(int)delay; 

@end

Toast.m

#import "Toast.h" 

@interface Toast() 

@end 

@implementation Toast 

+ (void)toast:(NSString *)message 
      :(UIView *) view 
      :(int)delay 
{ 
    CGRect initialFrame = CGRectMake(10, view.frame.size.height/2, 300, 40); 
    UILabel *flashLabel=[[UILabel alloc] initWithFrame:initialFrame]; 
    flashLabel.font=[UIFont fontWithName:@"Optima-Italic" size:19.0]; 
    flashLabel.backgroundColor=[UIColor whiteColor]; 
    flashLabel.layer.cornerRadius=9.0f; 
    flashLabel.clipsToBounds = YES; 
    flashLabel.numberOfLines=3; 
    flashLabel.textAlignment=NSTextAlignmentCenter; 
    CGSize maxSize = CGSizeMake(flashLabel.frame.size.width, MAXFLOAT); 
    CGRect labelRect = [message boundingRectWithSize:maxSize 
              options:NSStringDrawingUsesLineFragmentOrigin 
              attributes:@{NSFontAttributeName:flashLabel.font} 
              context:nil]; 

    //adjust the label the the new height. 
    CGRect newFrame = flashLabel.frame; 
    newFrame.size.height = labelRect.size.height * 2; 
    flashLabel.frame = newFrame; 
    flashLabel.text=message; 
    [view addSubview:flashLabel]; 
    flashLabel.alpha=1.0; 
    view.userInteractionEnabled=FALSE; 

    [UIView animateWithDuration:delay animations:^

     flashLabel.alpha=0.0f; 
    } 

    completion:^(BOOL finished) 
    {

我非常喜欢Bahai提出的MonoTouch解决方案。

以下不是替代品。只是一个准备好的方法为我工作。

private async Task ShowToast(string message, UIAlertView toast = null) 
    { 
     if (null == toast) 
     { 
      toast = new UIAlertView(null, message, null, null, null); 
      toast.Show(); 
      await Task.Delay(2000); 
      await ShowToast(message, toast); 
      return; 
     } 

     UIView.BeginAnimations(""); 
     toast.Alpha = 0; 
     UIView.CommitAnimations(); 
     toast.DismissWithClickedButtonIndex(0, true); 
    }

如果该方法是从一个后台线程（未在主UI线程）然后BeginInvokeOnMainThread需要这意味着只是这样称呼它调用。

BeginInvokeOnMainThread(() => 
{ 
ShowToast(message); 
});

这会阻止用户交互，直到显示Toast时，Android中的Toast并不是这种情况。 – 2016-04-15 11:02:06
