ios - 如何更改 TextView 的文本颜色？

Question

我试过使用:

    hintView.textColor = [UIColor greenColor];  



- (IBAction)secondHintq:(id)sender {

if(!btn2Pressed) {
    if((coins -10) >= 0){
        coins = coins -10;
        score = score -2;


coinsLabel.text = [NSString stringWithFormat:@"%d",coins];
hintView.text = @"Type in text here 2";

 [_candletwo setImage:[UIImage imageNamed:@"candle2_03.png"] forState:UIControlStateNormal];
        coinsLabel.text = [NSString stringWithFormat:@"%d",coins];
        self.candlethree.hidden = NO;
        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:0.5];


        CGPoint center = [_candlethree center];
        center.x = 160;
        center.y = 70;
        [_candlethree setCenter:center];

        [UIView commitAnimations];
        btn2Pressed = true;



    }
    else{
        //Show an alert that the user has not enough coins
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"TITLE" message:@"MESSAGE" delegate:nil cancelButtonTitle:@"RETURN BUTTON" otherButtonTitles:nil];
        [alert show];

    }
}
}

我怎样才能让它发挥作用？

Answer 1

也许尝试做这样的事情:

[hintView setTextColor:[UIColor greenColor]];

如果您使用的是 IB，还要确保 socket 连接正确。
