UIButton 标题被剪裁

Question

我有一个带有字体的自定义按钮。

customButtonSynchronize = [UIButton buttonWithType:UIButtonTypeCustom];
customButtonSynchronize.frame=CGRectMake(578, 27.5, 91, 29) ;
[customButtonSynchronize setBackgroundImage:[UIImage imageNamed:@"synchronize.png"]
                                   forState:UIControlStateNormal];
customButtonSynchronize.titleLabel.font = [UIFont fontWithName:@"HelveticaLTStd-Roman" size:14.0f];
[customButtonSynchronize setTitle:@"Sincronizzare" forState:UIControlStateNormal];
/////HERE//////////
customButtonSynchronize.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
customButtonSynchronize.contentVerticalAlignment = UIControlContentVerticalAlignmentTop;
customButtonSynchronize.contentEdgeInsets = UIEdgeInsetsMake(8, 0, 0, 0);
customButtonSynchronize.backgroundColor=[UIColor clearColor];
[customButtonSynchronize addTarget:self action:@selector(synchronizeDB:) forControlEvents:UIControlEventTouchUpInside];

但是上面的文字好像有点“Cut off”了。见“S”的顶部。

我不想改变按钮的框架，字体的大小。改变插图不能避免这个问题。是模拟器错误还是 helvetica 字体的问题？有什么解决办法吗？

将 uibutton 标题设置为 nil，然后使用文本创建标签并将子视图添加到 uibutton 就是这样，现在它将根据您的需要正确显示文本
