兼容 iOS 7 的 Alert Controller

[Elethom]

Features:

• 和 UIAlertController 使用相同的 API;
• 自帶 -show 和 -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

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.

输入帐号密码或文本的那种alert怎么写？

[xhacker]

@Livid: 在 iOS 上代码的字体有问题。

[Elethom]

@xhacker
Mac 上也有問題.

[Elethom]

@xhacker
@Livid
Fallback 中的字體我一個都沒有...

[Livid]

@xhacker
@Elethom

收到，我现在调整。

[Elethom]

@Livid
建議調整為可左右滾動的, 折行很難看.

[Livid]

@xhacker
@Elethom

现在加入了 Menlo

[Elethom]

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

[Livid]

@Elethom 个人最爱的代码字体。

[Elethom]

@Livid

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.

[Livid]

@Elethom 好的，现在调整。

[Esay]

酷，给你补个截图（代码最后一行的 Controller 大小写写错了）

[Elethom]

@Livid
似乎還沒 update?

@Esay
Thanks! 已修改.
