小鍵盤隱藏UITextField

Question

我有10個UITextField'正在整個屏幕。當我想改變它們時，我在半屏上得到鍵盤，所以我不能改變'隱藏'字段。 有沒有人知道解決方案？

Answer 1

您需要在調用鍵盤時向上移動框架。

- (void)keyboardWillShow:(NSNotification *)aNotification 
{ 
    self.frame = CGRectMake(0,-[size of keyboard],self.frame.size.width,self.frame.size.height); 
} 

Answer 2

i have taken from here：

- (void)textFieldDidBeginEditing:(UITextField *)textField { 
    if (textField == textField1) { 
     [UIView beginAnimations:nil context:NULL]; 
     [UIView setAnimationDelegate:self]; 
     [UIView setAnimationDuration:0.5]; 
     [UIView setAnimationBeginsFromCurrentState:YES]; 
     textfield1.frame = CGRectMake(textfield1.frame.origin.x, (textfield1.frame.origin.y - 100.0), textfield1.frame.size.width, textfield1.frame.size.height); 
     [UIView commitAnimations]; 
    } else if (textField == textField2) { 
     [UIView beginAnimations:nil context:NULL]; 
     [UIView setAnimationDelegate:self]; 
     [UIView setAnimationDuration:0.5]; 
     [UIView setAnimationBeginsFromCurrentState:YES]; 
     textfield2.frame = CGRectMake(textfield2.frame.origin.x, (textfield2.frame.origin.y - 100.0), textfield2.frame.size.width, textfield2.frame.size.height); 
     [UIView commitAnimations]; 
    } 
} 
- (void)textFieldDidEndEditing:(UITextField *)textField { 
    if (textField == textField1) { 
     [UIView beginAnimations:nil context:NULL]; 
     [UIView setAnimationDelegate:self]; 
     [UIView setAnimationDuration:0.5]; 
     [UIView setAnimationBeginsFromCurrentState:YES]; 
     textfield1.frame = CGRectMake(textfield1.frame.origin.x, (textfield1.frame.origin.y + 100.0), textfield1.frame.size.width, textfield1.frame.size.height); 
     [UIView commitAnimations]; 
    } else if (textField == textField2) { 
     [UIView beginAnimations:nil context:NULL]; 
     [UIView setAnimationDelegate:self]; 
     [UIView setAnimationDuration:0.5]; 
     [UIView setAnimationBeginsFromCurrentState:YES]; 
     textfield2.frame = CGRectMake(textfield2.frame.origin.x, (textfield2.frame.origin.y + 100.0), textfield2.frame.size.width, textfield2.frame.size.height); 
     [UIView commitAnimations]; 
    } 

和觸摸：

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 

{ [文本字段resignFirstResponder]; }

希望能幫助你。
