ios關於鍵盤遮擋的簡單方法

1 利用UIScrollview 的設定使得整體上移

把控制項都放在scrollview上面，然後利用當使用者點擊的時候，設定scrollview 的CGPointMake(scroll.contentOffset.x, y+100)就可以達到效-(void)textFieldDidB

-(void)textFieldDidBeginEditing:(UITextField *)textField{    UIScrollView *scroll=(UIScrollView *)self.superview;    float y = 200;    [scroll setContentOffset:CGPointMake(scroll.contentOffset.x, y+100) animated:YES];        }- (void)textFieldDidEndEditing:(UITextField *)textField {            UIScrollView *scroll = (UIScrollView *)self.superview;    [scroll setContentOffset:CGPointMake(scroll.contentOffset.x, 0) animated:YES];    return;}

記得這些都是放在scrollview上的控制項，

2 第二中的方法是利用就是把父類的view整體上移，

#pragma mark textKeyBoardHeight method//先響應Textfiled方法，因為有多個控制項，所以利用tag區分-(void)textFieldDidBeginEditing:(UITextField *)textField{    [self slideFrameUp:nil withTag:textField.tag];}-(void)textFieldDidEndEditing:(UITextField *)textField{        [self slideFrameDown:nil withTag:textField.tag];}//設定上移還是下降-(void) slideFrameUp:(id)up withTag:(NSInteger)tag{    [self slideFrame:YES withTag:tag];}-(void) slideFrameDown:(id)down withTag:(NSInteger)tag{    [self slideFrame:NO withTag:tag];}-(void) slideFrame:(BOOL) up withTag:(NSInteger)tag{//設定上移的多少    int movementDistance=1;    if (tag==3) {        movementDistance =70;    }else if (tag==4){        movementDistance = 100; // tweak as needed    }//判斷是上移還是下降    const float movementDuration = 0.3f; // tweak as needed    int movement = (up ? -movementDistance : movementDistance);    //動畫設定    [UIView beginAnimations: @"anim" context: nil];    [UIView setAnimationBeginsFromCurrentState: YES];    [UIView setAnimationDuration: movementDuration];    self.frame = CGRectOffset(self.frame, 0, movement);    [UIView commitAnimations];}

上面就是簡單的不被鍵盤遮擋的方法，
