Question

如果我使用此代码将图像放置在另一个按钮上而没有间距，我不知道如何水平对齐按钮（x轴）。

这是我用过的代码。提前感谢答案。

private static final Pattern matchPat = Pattern.compile("Hello(xyz)*Hello");
String line = "HelloxyzxyzxyzHello";
Matcher x8 = matchPat.matcher(line);

试试这段代码：

    NSArray *arr1 = [pJson1 objectForKey:@"Response"];
    int x ;
    for (int i=0; i<arr1.count; i++)
    {

       UIButton *btnNew = [[UIButton alloc]initWithFrame:CGRectMake(x,20, 50, 30)];
        btnNew.backgroundColor = [UIColor blackColor];
        NSString *str = [NSString stringWithFormat:@"%@",[[arr1 objectAtIndex:i]objectForKey:@"name"]];
        [btnNew setTitle:str forState:UIControlStateNormal];
        CGSize stringsize = [str sizeWithFont:[UIFont systemFontOfSize:14]];
        //or whatever font you're using
        btnNew.tag = i;
        [self.categoryView addSubview:btnNew];
        x += 55;
    }

如何在ios中的View中以水平方式编程创建按钮
