    这是一个创建于 3677 天前的主题,其中的信息可能已经有所发展或是发生改变。

    Features:

    • 和 UIAlertController 使用相同的 API;
    • 自帶 -show-dismiss, 不需要考慮從哪個 view controller present 的問題;
    • 自動忽略長度為 0 的 title, 不會在 iOS 8 出現一個難看的空 title.

    Known issues:

    • text field 在 iOS 7 和 iOS 8 的差別太大, 無法同時支持;
    • controller 繼承自 NSObject, 無法當做普通的 view controller 使用 (下個版本修改).

    PRAlertController

    Cocoapods

    Alert controller with the same APIs as iOS 8 SDK (text field not supported), compatible with iOS 7.

    Installation

    With CocoaPods

    In your Podfile:

    pod 'PRAlertController'
    

    Usage

    It has exactly the same APIs as iOS 8 SDK does except the text field part. Besides, with -show, -dismiss methods you can pop up alerts wherever you want without having to worry about how to get current view controller's pointer.

    Example:

    PRAlertController *alertController = [PRAlertController alertControllerWithTitle:@"Title"
                                                                             message:@"This is the message."
                                                                      preferredStyle:PRAlertControllerStyleAlert];
    PRAlertAction *firstAction = [PRAlertAction actionWithTitle:@"First"
                                                          style:PRAlertActionStyleDefault
                                                        handler:^(PRAlertAction *action) {
                                                            [self doFirstAction];
                                                        }];
    PRAlertAction *secondAction = [PRAlertAction actionWithTitle:@"Second"
                                                           style:PRAlertActionStyleDefault
                                                         handler:^(PRAlertAction *action) {
                                                             [self doSecondAction];
                                                         }];
    PRAlertAction *destructiveAction = [PRAlertAction actionWithTitle:@"Destructive"
                                                                style:PRAlertActionStyleDestructive
                                                              handler:^(PRAlertAction *action) {
                                                                  [self doDestructiveAction];
                                                              }];
    PRAlertAction *cancelAction = [PRAlertAction actionWithTitle:@"Cancel"
                                                           style:PRAlertActionStyleCancel
                                                         handler:^(PRAlertAction *action) {
                                                             [self doCancelAction];
                                                         }];
    [alertController addAction:firstAction];
    [alertController addAction:secondAction];
    [alertController addAction:destructiveAction];
    [alertController addAction:cancelAction];
    [alertcontroller show];
    

    Easy as it seems.

    建議調整為可左右滾動的, 折行很難看.

    搜索了一下, 原來 Panic Sans 是 Coda 附帶的字體, 難怪叫做 "Panic". XD

    似乎沒有單獨的下載?

    試了一下, 給代碼部份的 CSS 加上:
    white-space: pre;
    overflow-x: scroll;
    這樣比較好, 可以橫向滾動, 換行不好看.
