为什么在以编程方式创建时UIButton模糊不清

Question

我创建了一个像这样的uibutton：

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button.frame = CGRectMake(280, 320, 100, 30);
[button setTitle:@"World" forState:UIControlStateNormal];
[button addTarget:self action:@selector(button:) forControlEvents:UIControlEventTouchUpInside];
button.backgroundColor= [UIColor clearColor];
[cell.contentView addSubview:button];

按钮的文字看起来很锋惠，有人知道为什么吗？

Answer 1

更改

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

到

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
                                                        ^^^^^^

一切都会好..

Answer 2

尝试给予Font：

 // Configure the cell...
    UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    button.frame = CGRectMake(0, 0, 100, 30);
    [button setTitle:@"World" forState:UIControlStateNormal];
    [button addTarget:self action:@selector(button:) forControlEvents:UIControlEventTouchUpInside];
    button.titleLabel.font=[UIFont fontWithName:@"HelveticaNeu-CondensedBold" size:16];
    button.backgroundColor= [UIColor clearColor];
    [cell.contentView addSubview:button];
