UIAlertViewで問題が発生しました。繰り返しソースが見つかりませんでした。

Question

私の問題は、ユーザーが重要ではない場所をクリックしたときに発生します。alertViewが呼び出されました。何度も何度も何度も何度も空いていることを示しています。しかし、幽霊警報はどこにも壊れていません誰がそれを投げているのか分かりません、ただ感情的な見方です。

ビューがどこに呼び出されているかを特定する方法に関するヒントを教えてください。

Answer 1

持つあなたのViewControllerを確認を貼り付けることはできませんUialertviewdelegate。

1. あなたalertview.delegateをログ

2. それはuialertviewdelegate関数を呼び出していないことのViewControllerのあなたのスーパークラスを確認してください。

3. それはUIAlertControllerある場合は、チェックviewwillappear、彼らはあなたがあなたのAlertViewのコンテンツをキャッチすることができます

Answer 2

[alertviewショー]呼び出すことはありませんviewdidappear、viewwilldisappear（スーパークラスすぎ）と知り、コンテンツがまったくない場合は、提示しないでください！

これを行うには、alertViewを表示するメソッドに渡すメッセージをチェックします。

ただし、あなたのメソッドshowAreYouReadyToSubmitFormMsgが見つかりません。唯一のテストのために

Answer 3

：あなたはalertviewのために列挙型を取るのはなぜ

サブクラスUIAlertViewすなわち@interface MyAlertView : UIAlertView

その後MyAlertView すなわちMyAlertView *someAlert = [[MyAlertView alloc] init.......];

からUIAlertViewのすべてのインスタンスを置き換えるその後

-(void)show { 

[super show]; 

//Your breakpoint here 

OR 

NSLog([NSThread callStackSymbols]); 
} 

Answer 4

を上書き？表示する必要がある場合は、UIAlertViewのインスタンスを作成してください。あなたは2つの文字列パラメータalertviewマッサージとタイトルとメソッドを渡すことができる1つのメソッドを作成することができますこのタイトルとマッサージのalertviewを示しています。
