UIScrollView中的UITextField鍵盤遮擋問題的最簡單解決辦法

兩步:

1重載textFieldDidBeginEditing

- (void)textFieldDidBeginEditing:(UITextField *)textField
{
    foucsTextField = textField;
    s_mainScrollView.contentSize = CGSizeMake(SCREEN_WIDTH,SCREEN_HEIGHT +216);//原始滑動距離增加鍵盤高度
    CGPoint pt = [textField convertPoint:CGPointMake(0, 0) toView:s_mainScrollView];//把當前的textField的坐標映射到scrollview上
    if(s_mainScrollView.contentOffset.y-pt.y+NAVIGATION_BAR_HEIGHT<=0)//判斷最上面不要去滾動
        [s_mainScrollView setContentOffset:CGPointMake(0, pt.y-NAVIGATION_BAR_HEIGHT) animated:YES];//華東

}</pre>


2:重載textFieldShouldReturn

- (BOOL)textFieldShouldReturn:(UITextField*)theTextField
{
    {
        [theTextField resignFirstResponder];


    //開始動畫 
    [UIView beginAnimations:nil context:nil];  
    //設定動畫持續時間 
    [UIView setAnimationDuration:0.3];
    s_mainScrollView.frame = CGRectMake(0, NAVIGATION_BAR_HEIGHT, __SCREEN_WIDTH, __SCREEN_HEIGHT);
    s_mainScrollView.contentSize = CGSizeMake(__SCREEN_WIDTH,__SCREEN_HEIGHT);
    //動畫結束 
    [UIView commitAnimations]; 


}
return YES;

}</pre>



這樣就可以自動的滑動scrollview里面的輸入控件了.
