如何在註冊的水龍頭後從工作中刪除或停止表格視圖中的按鈕

我在添加行的表格視圖中有一個按鈕。最多五行後，我想停止添加用戶。目前，我會在按鈕按下5個按鍵後顯示提醒。如何在註冊的水龍頭後從工作中刪除或停止表格視圖中的按鈕

如何阻止用戶使用此按鈕？設置爲隱藏不會工作作爲一個自定義的子類，property hidden未在類

- (void)viewDidLoad 
{ 

[super viewDidLoad]; 

UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectZero]; 
titleLabel.backgroundColor = [UIColor clearColor]; 
titleLabel.textColor = [UIColor whiteColor]; 
titleLabel.shadowColor = [UIColor darkGrayColor]; 
titleLabel.text = self.distributionBoard.dbRef; 
titleLabel.font = [UIFont boldSystemFontOfSize:15.0f]; 
[titleLabel sizeToFit]; 
self.navigationItem.titleView = titleLabel; 

self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(doneButtonPressed:)]; 

// Add new appliance button to the table view's footer view 
UIView *footerView = [[UIView alloc] initWithFrame:CGRectMake(10.0f, 0, 300.0f, 100.0f)]; 
footerView.backgroundColor = [UIColor clearColor]; 
UIButton *newBoardButton = [UIButton buttonWithType:UIButtonTypeContactAdd]; 
CGRect buttonFrame = newBoardButton.frame; 
buttonFrame.origin.x = footerView.frame.size.width - buttonFrame.size.width; 
newBoardButton.frame = buttonFrame; 
[newBoardButton addTarget:self action:@selector(addCircuitButtonPressed:) forControlEvents:UIControlEventTouchUpInside]; 
[footerView addSubview:newBoardButton]; 
self.tableView.tableFooterView = footerView; 




}

發現.....

////limit to five appliances 

- (void)addCircuitButtonPressed:(id)sender { 
LogCmd(); 
Circuit *circuit = [[ICCircuitManager manager] newCircuit]; 
circuit.distributionBoard = self.distributionBoard; 
circuit.circuitReference = [NSString stringWithFormat:@"%d", [self.circuits count] + 1]; 
circuit.createdAt = [NSDate date]; 
circuit.modifiedAt = [NSDate date]; 
[self.distributionBoard addCircuitsObject:circuit]; 
[self loadData]; 
[self.tableView reloadData]; 

{ 
    m_buttonTouchCount++; 
    if (m_buttonTouchCount == 4) 



    { 
     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"iCertifi" 
                 message:@"Maximum number of appliances reached" 
                 delegate:nil 
               cancelButtonTitle:@"Ok" 
               otherButtonTitles:nil]; 
     [alert show]; 
     // m_buttonTouchCount = 0; // reset to 0 here if required. 
    } 



    } 
}

哪個是自定義子類？ newBoardButton？看起來像你的代碼中的UIButton，並且應該隱藏屬性。 – iDev

是的，這就是我需要做的！我試圖隱藏錯誤的項目。 – JSA986

如果你有AlertView你可以輸入這個代碼，以禁用按鈕：

[(UIButton *)sender setEnabled:NO];

或隱藏按鈕：

[(UIButton *)sender setHidden:YES];

非常感謝，發件人工作後，刪除了支架！ '[（UIButton *）sender setHidden：YES];' – JSA986

你是對的括號:-)我編輯它 –
