Toast for iOS

Toast 是一个基于 Objective-C 语言的范畴（category）框架，它向 UIView 对象添加 Toast 通知。它简单、轻便且易于使用。大多数 Toast 通知都可以通过一行代码触发。

如果你在使用 Swift? 这个框架也有一个原生的 Swift 版本支持: Toast-Swift

简单示例

// 基本用法
[self.view makeToast:@"This is a piece of toast."];

// 指定位置和持续时间
// duration：显示 Toast 的持续时间，默认显示 3.0 秒后自动消失。
// position：显示 Toast 的位置，
// 可选位置参数：CSToastPositionTop、CSToastPositionCenter、CSToastPositionBottom
[self.view makeToast:@"This is a piece of toast with a specific duration and position." 
            duration:3.0
            position:CSToastPositionTop];

// 带所有可自定义配置选项的 Toast
[self.view makeToast:@"This is a piece of toast with a title & image"
            duration:3.0
            position:[NSValue valueWithCGPoint:CGPointMake(110, 110)]
               title:@"Toast Title"
               image:[UIImage imageNamed:@"toast.png"]
               style:nil
          completion:^(BOOL didTap) {
              if (didTap) {
                  NSLog(@"completion from tap");
              } else {
                  NSLog(@"completion without tap");
              }
          }];
                
// 显示加载活动指示器的 Toast，这个方法类似于 MBProgressHUD
[self.view makeToastActivity:CSToastPositionCenter];

// 显示自定义 UIView 的 Toast
[self.view showToast:myView];

注：Toast 框架中的 makeToast: 这个方法其实也可以用 MBProgressHUD 中的方法实现：

// 封装成通用一个方法
- (void)showMBProgressHudWithString:(NSString *)string {
    MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
    
    // Set the text mode to show only text
    hud.mode = MBProgressHUDModeText;
    hud.label.text = NSLocalizedString(string, @"HUD message title");
    // 移动到底部中心
    hud.offset = CGPointMake(0.f, MBProgressMaxOffset);
    // 3秒后自动消失
    [hud hideAnimated:YES afterDelay:3.f];
}

另外，Toast 中显示 Loading 动画的方法 makeToastActivity: 你也可以等同于 MBProgressHUD 中的这个方法：

[MBProgressHUD showHUDAddedTo:self.view animated:YES];

等等，还有更多!

// CSToastStyle 类是用来创建自定义样式的
CSToastStyle *style = [[CSToastStyle alloc] initWithDefaultStyle];

// this is just one of many style options
// 文本颜色
style.messageColor = [UIColor orangeColor];

// present the toast with the new style
[self.view makeToast:@"This is a piece of toast."
            duration:3.0
            position:CSToastPositionBottom
               style:style];

// or perhaps you want to use this style for all toasts going forward?
// just set the shared style and there's no need to provide the style again
// 设置一个共享的自定义样式，然后通用所有 Toast
[CSToastManager setSharedStyle:style];

// toggle "tap to dismiss" functionality
// 打开 “点击以关闭” 功能
[CSToastManager setTapToDismissEnabled:YES];

// toggle queueing behavior
// 按顺序显示 Toast
[CSToastManager setQueueEnabled:YES];

// immediately hides all toast views in self.view
// 立即隐藏所有正在显示的 Toast
[self.view hideAllToasts];
