的Objective-C：

CGRect someRect = CGRectMake(0.0, 0.0, 100.0, 30.0); 
UITextField* text = [[UITextField alloc] initWithFrame:someRect]; 
UIView* view = [[UIView alloc] initWithFrame:someRect]; 

[view addSubview:text];

斯威夫特：

let someFrame = CGRect(x: 0.0, y: 0.0, width: 100.0, height: 30.0) 

let text = UITextField(frame: someFrame) 
let view = UIView(frame: someFrame) 
view.addSubview(text)

什麼框架？ – galactikuh 2016-01-24 18:47:56

@galactikuh你是什麼意思？框架是放置視圖的矩形。 – Skie 2016-01-25 09:10:32

如果這是答案的重要部分，那麼框架的創建應該包含在代碼中。 – galactikuh 2016-01-25 14:14:27

如果你想要一個看起來像在Interface Builder中的文本字段：

UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(10, 200, 300, 40)]; 
textField.borderStyle = UITextBorderStyleRoundedRect; 
textField.font = [UIFont systemFontOfSize:15]; 
textField.placeholder = @"enter text"; 
textField.autocorrectionType = UITextAutocorrectionTypeNo; 
textField.keyboardType = UIKeyboardTypeDefault; 
textField.returnKeyType = UIReturnKeyDone; 
textField.clearButtonMode = UITextFieldViewModeWhileEditing; 
textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;  
textField.delegate = self; 
[self.view addSubview:textField]; 
[textField release];

'contentVerticalAlignment'是這裏至關重要的元素 – 2013-02-20 23:11:16

+1 @NathanielSymer：我花了1個小時計算出來，直到我在這裏看到您的評論... :)謝謝.. – 2013-03-22 11:06:05

非常感謝@ioshero這真的是一個很好的答案...恕我直言，我認爲應該被標記爲一個正確的答案。你所涵蓋的UITextField的不同參數的事實是非常棒的。再次感謝您的回答。 – Jiraheta 2013-09-05 20:37:47

在斯威夫特2.0：

let sampleTextField = UITextField(frame: CGRectMake(20, 100, 300, 40)) 
sampleTextField.placeholder = "Enter text here" 
sampleTextField.font = UIFont.systemFontOfSize(15) 
sampleTextField.borderStyle = UITextBorderStyle.RoundedRect 
sampleTextField.autocorrectionType = UITextAutocorrectionType.No 
sampleTextField.keyboardType = UIKeyboardType.Default 
sampleTextField.returnKeyType = UIReturnKeyType.Done 
sampleTextField.clearButtonMode = UITextFieldViewMode.WhileEditing; 
sampleTextField.contentVerticalAlignment = UIControlContentVerticalAlignment.Center 
sampleTextField.delegate = self 
self.view.addSubview(sampleTextField)
