兼容 iOS 7 的 Alert Controller

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

@Elethom 个人最爱的代码字体。

@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.
