Question

我有一个名为courseOptionsView的子视图，我希望在某些条件下显示和隐藏按钮。当我使用滑动手势时，视图正常工作并且位置正确，但是当我使用另一个按钮对该函数进行完全相同的调用时，它会重新定位它，但它会将其重新定位到它所在的原始位置而不是坐标我是发送。：/我很难过。

*编辑似乎当我使用++或 - 来自cHNumber它会重置子视图。有什么想法吗？

 IBOutlet UIView *courseOptionsView; 
- (IBAction)nextHole:(id)sender;
- (IBAction)showCourseOptionsView:(id)sender;
- (IBAction)hideCourseOptionsView:(id)sender;


//show and hide functions
-(void) showCourseOptions{
    if(activeRound){
        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
        [UIView setAnimationDuration:1.0];
        [courseOptionsView setFrame:CGRectMake(50, 44, 200, 455)];
    }
}
-(void) hideCourseOptions{
    if(activeRound){
        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
        [UIView setAnimationDuration:1.0];
        [courseOptionsView setFrame:CGRectMake(-200, 44, 200, 455)];
    }
}
// swipe calls
- (IBAction)showCourseOptionsView:(id)sender {
    [self showCourseOptions];
}

- (IBAction)hideCourseOptionsView:(id)sender {
    [self hideCourseOptions];
}
//button call
- (IBAction)nextHole:(id)sender
{
    int totalStrokes = 0;
    int totalPlusMinus = 0;
    //[courseOptionsView setFrame:CGRectMake(0, 44, 200, 455)];
    //[self showCourseOptions];

    //save current hole
    if(cHStrokes != [[currentRound objectForKey:[NSString stringWithFormat:@"hole%i",cHNumber]] intValue] ||
       cHPutts != [[currentRound objectForKey:[NSString stringWithFormat:@"hole%i_putts",cHNumber]] intValue]){
        [self saveCurrentHole];
    }
    // calculate and display +/- and strokes
    for (int i = 0; i < ([currentRound count]/2); i++){
        totalStrokes += [[currentRound objectForKey:[NSString stringWithFormat:@"hole%i",i+1]] intValue];
        totalPlusMinus += [[[selectedScoreCardData objectAtIndex:0] objectForKey:[NSString stringWithFormat:@"hole%i_par",i+1]] intValue];
    }
    totalPlusMinus = totalStrokes - totalPlusMinus;
    self.totalStrokesLabel.text = [NSString stringWithFormat:@"%i", totalStrokes];
    self.totalPlusMinusLabel.text = [NSString stringWithFormat:@"%i",totalPlusMinus];
        //set to next hole
    /*------------------- 
    |   SHOW VIEW HERE 
    --------------------*/
    if(cHNumber == 17){
        self.nextHoleButton.enabled = NO;
        [self showCourseOptions];
    }
    if(cHNumber == 1){
        self.prevHoleButton.enabled = YES;
    }
    cHNumber ++;
    self.cHNumberLabel.text = [NSString stringWithFormat:@"%i", cHNumber];
    [self populateScoreCard];
    [strokePickerView reloadAllComponents];
    if(([currentRound count]/2) < cHNumber){

        [strokePickerView selectRow:cHStrokes - 1 inComponent:0 animated:YES];
        [strokePickerView selectRow:0 inComponent:1 animated:YES];
    }else{
        [strokePickerView selectRow:[[currentRound objectForKey:[NSString stringWithFormat:@"hole%i",cHNumber]] intValue] - 1 inComponent:0 animated:YES];
        [strokePickerView selectRow:[[currentRound objectForKey:[NSString stringWithFormat:@"hole%i_putts",cHNumber]] intValue] inComponent:1 animated:YES];
    }
}

我想也许在您定位视图后，您正在调用另一个更改布局的函数。可能的候选人是populateScoreCard。

无法正确定位子视图
