正確AutoresizingMask

我有一個視圖出現在其父視圖肖像模式的中心，我應該使用什麼autoresizemask，以便它也出現在橫向模式的中心。它的大小應該保持不變。我只是希望它的原點應該自動在這一點上自動移動，以便它出現在中心位置。請任何幫助嗎？正確AutoresizingMask

我已經給

[parentView setAutoResizesSubview:YES]; 

parentView.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth;

// horizontal 
childView.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin; 

// vertical 
childView.autoresizingMask = UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin; 

// both 
childView.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin;

喲感謝的人... –

If you are using swift: 
// horizontal 
childView.autoresizingMask = [.flexibleLeftMargin, .flexibleRightMargin] 
// vertical 
childView.autoresizingMask = [.flexibleTopMargin, .flexibleBottomMargin] 
// both 
childView.autoresizingMask = [.flexibleLeftMargin, .flexibleRightMargin, .flexibleTopMargin, .flexibleBottomMargin]

斯威夫特3：

childView.translatesAutoresizingMaskIntoConstraints = false 

childView.autoresizingMask = [.flexibleTopMargin, .flexibleBottomMargin, .flexibleLeftMargin, .flexibleRightMargin]
