IOS-如何調整programitically創建的UILabel，UITextView的，UITextField，用於programitically創建滾動視圖按方向變化

Question

我已經創建程序創建scollview它會調整爲每orientation.But上滾動視圖創建的UI元素是固定的它是不changes.Now我需要改變的UILabel，UITextView的，大小的UITextField按方向我試着用下面的代碼，但它不是爲我工作。

CGRect textfieldFrame = CGRectMake(12.0, 20.0, textView.frame.size.width-20,  textView.frame.size.height-424); 
//CGRect textfieldFrame = CGRectMake(12.0, 20.0, 270, 35);/* I used For fixed size 
UITextField *textField = [[UITextField alloc] initWithFrame:textfieldFrame]; 
[textField setAutoresizesSubviews:YES]; 
[textField setAutoresizingMask: 
UIViewAutoresizingFlexibleWidth | 
UIViewAutoresizingFlexibleHeight]; 
textField.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; 

現在我必須根據方向change.Please幫我解決這個問題。

嘿Anupama試試這個

UIInterfaceOrientation orientation = [UIApplication 
    sharedApplication].statusBarOrientation; 

    if(orientation == UIInterfaceOrientationLandscapeRight || 
    orientation == UIInterfaceOrientationLandscapeLeft) 

     { 
      // your frame for landscape    

     } 
    else if(orientation==UIInterfaceOrientationPortrait) 
     { 
     // your frame for portrait 

     }
