UITextField не работает программно?

Question

Я создал UITextField программно все работает хорошо, но мой UITextField не редактируя, то есть, когда я пытаюсь нажать на UITextField его не здесь работает мой образец кода,

CGRect frame = CGRectMake(16, 281, 288, 47); 
cycle = [[UITextField alloc] initWithFrame:frame]; 
cycle.placeholder = @"Cycle Number"; 
cycle.textColor = [UIColor blackColor]; 
cycle.font = [UIFont systemFontOfSize:17.0]; 
cycle.borderStyle = UITextBorderStyleLine; 
cycle.autocorrectionType = UITextAutocorrectionTypeYes; 
cycle.keyboardType = UIKeyboardTypeDefault; 
cycle.clearButtonMode = UITextFieldViewModeWhileEditing; 
cycle.delegate = self; 
cycle.text = @""; 
[self.view addSubview:cycle]; 

Answer 1

'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];' 

Below delegate methods must use 

-(BOOL)textFieldShouldReturn:(UITextField *)textField 
{ 
    [self endEditing]; 
    [textField resignFirstResponder]; 
    return YES; 

} 

- (void)textFieldDidBeginEditing:(UITextField *)textField { 
     [self beginEditing:textField]; 
} 

- (void)textFieldDidEndEditing:(UITextField *)textField { 


    // [self endEditing]; 
} 



I hope you it is useful for u
