採用獨特的鍵

Question

NSKeyed存檔警告我越來越多的日誌警告，這樣，當我把我的應用程序到測試保存/恢復狀態時，使用home鍵的背景。

2014-02-13 20:13:08.275 FlowTrak[16777:60b] *** NSKeyedArchiver warning: replacing existing 
value for key 'UIStateRestorationViewControllerStoryboard'; probable duplication of encoding 
keys in class hierarchy 

該應用程序運行在設備上的罰款，和所有的狀態恢復/保存的作品，因爲它應該，但我很想擺脫這些警告。沒有一噸約這些警告信息在那裏，但是從我讀過，我應該去的好，只要我使用的唯一密鑰，我保留每個UI項目。

上整理了這一點任何想法？謝謝。

這裏是我的代碼：

// Restoration of text fields 
-(void)encodeRestorableStateWithCoder:(NSCoder *)coder 
{ 
    // start level text 
    [coder encodeObject:_startLevel.text forKey:@"startText"]; 
    [super encodeRestorableStateWithCoder:coder];

    [coder encodeObject:_stopLevel.text forKey:@"stopText"]; 
    [super encodeRestorableStateWithCoder:coder]; 

    // start time label 
    [coder encodeObject:_startTimeLabel.text forKey:@"startTimeText"]; 
    [super encodeRestorableStateWithCoder:coder];

    [super encodeRestorableStateWithCoder:coder];

    // calculate button state

    // resume button state 
    [coder encodeBool:self.resume.enabled forKey:@"resumeButtonState"]; 
    [super encodeRestorableStateWithCoder:coder]; 

    // tank selector segmented control 
    [coder encodeInteger:self.tankControl.selectedSegmentIndex forKey:@"tankIndex"]; 
    [super encodeRestorableStateWithCoder:coder]; 

    // start time for equation 
    [coder encodeDouble:startTime forKey:@"startTimeEquation"]; 
    [super encodeRestorableStateWithCoder:coder];

    // tank selector segmented control for equation

你爲什麼叫超級實施多次？只調用一次！
