解決辦法

解決輸入框位置顯示不對(duì)

- (CGRect)rightViewRectForBounds:(CGRect)bounds {
    CGRect rightViewRect = [super rightViewRectForBounds:bounds];

    if (@available(iOS 13.0, *)) {
        
        CGFloat left = self.frame.size.width - self.rightView.frame.size.width;
        CGFloat top = round((self.frame.size.height - self.rightView.frame.size.height)/2.0);
        rightViewRect = CGRectMake( left, top, self.rightView.frame.size.width , self.rightView.frame.size.height);
    } else {
        
    }

    return rightViewRect;
}


- (CGRect)leftViewRectForBounds:(CGRect)bounds {
    CGRect leftViewRect = [super leftViewRectForBounds:bounds];

    if (@available(iOS 13.0, *)) {
        CGFloat top = round((self.frame.size.height - self.leftView.frame.size.height)/2.0);

        leftViewRect = CGRectMake(0, top, self.leftView.frame.size.width, self.leftView.height);

    } else {
        
    }
    return leftViewRect;
}

喜歡的話(huà)，給個(gè)星星喲，如果沒(méi)有解決你的問(wèn)題，也可以留言，我看到了，會(huì)想想解決辦法的
