ios-檢測outletcollection中所有項目

檢測outletcollection中所有項目

在進入下一個視圖中需要確保當前的控制段都被選中了

-(void)checkAllSegments
{   BOOL alertShown;
    alertShown = NO;
    for (UISegmentedControl *swItem in allSegmentControlOutlet) {
        int selectedSegment = swItem.selectedSegmentIndex;
        swItem.segmentedControlStyle = UISegmentedControlStyleBar;
//didPass = YES;
        if (selectedSegment == -1) {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Fill in all forms"
                                                            message:@"Please go back and fill in missing info"
                                                           delegate:nil
                                                  cancelButtonTitle:@"OK"                                                  otherButtonTitles:nil];

           // [swItem setTintColor:[UIColor redColor]];
            if (!alertShown) {
                [alert show];
                alertShown = YES;
                didPass = NO;
                return;
            }
        }
    }
    if (didPass) {
        [self performSegueWithIdentifier:@"ToHiring" sender:self];
        }
}

但是我不知道應該將 didPass = YES;放到哪，這句代碼所在的位置會被注釋掉。除非最後一條循環完成。有沒有更好的方法解決？

最佳回答：

給你改一下。

 -(void)checkAllSegments
    {   BOOL alertShown;
        alertShown = NO;
        for (UISegmentedControl *swItem in allSegmentControlOutlet) {
            int selectedSegment = swItem.selectedSegmentIndex;
            swItem.segmentedControlStyle = UISegmentedControlStyleBar;
    //didPass = YES;
            if (selectedSegment == -1) {
                alertShown=YES;
                break;  /////如果有一個沒有被選擇，直接退出for循環
            }
        }
        if (alertShown) {
              UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Fill in all forms"
                                         message:@"Please go back and fill in missing info"
                                         delegate:nil
                                         cancelButtonTitle:@"OK"
                                         otherButtonTitles:nil];
        }else {
           [self performSegueWithIdentifier:@"ToHiring" sender:self];
        }

    }
