改變UIButton的標題不起作用

Question

我在tableview單元格中添加了一個按鈕。 我的問題是當我在調用方法pressHonkBtn:(id)sender上更改其標題時pressHonkBtn:(id)sender它沒有更改其標題。

怎么解決這個問題。

Answer 1

使用您的代碼：

Objective-C的：

-(IBAction)pressHonkBtn:(id)sender
{
    UIButton *tempBtn = (UIButton *)sender;
    [tempBtn setTitle:@"YOUR_TITLE" forState:UIControlStateNormal];// YOUR_TITLE is your button title
    [tempBtn setTitle:@"YOUR_TITLE" forState:UIControlStateHighlighted];
}

迅速：

someUIButton.setTitle("String To Set", forState: UIControlState.Normal)

希望它能幫到你。

Answer 2

請嘗試使用這個......它會正常工作。

-(IBAction)pressHonkBtn:(id)sender
{
    UIButton *btn = (UIButton *)sender;
    [btn setTitle:@"title" forState:UIControlStateNormal];
}

Answer 3

試試這個：

-(IBAction)pressHonkBtn:(id)sender
{
    UIButton *btn = (UIButton *)sender;

    [btn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    [btn setTitleColor:[UIColor blackColor] forState:UIControlStateHighlighted];

    [btn setTitle:@"title" forState:UIControlStateNormal];
    [btn setTitle:@"title" forState:UIControlStateHighlighted];
}

Answer 4

由於您正在接收id作為參數，因此您需要鍵入將其轉換為UIButton。

-(IBAction)pressHonkBtn:(id)sender
 {
    UIButton *senderBtn = (UIButton *)sender;

    [senderBtn setTitle:[NSString stringWithFormat:@"Title"] forState:UIControlStateNormal];
 }
