有没有办法在UIActionSheet中更改标题字体大小？ [英] Is there any way to change the title font size in a UIActionSheet?

问题描述

字体非常小，有些人难以阅读，所以我想让它更接近下面按钮上使用的字体大小。

The font is very small and hard for some to read so I'd like to make it closer to the font size used on the buttons below it.

推荐答案

您可以在show方法之后更改字体属性（如showFromBarButtonItem），如下所示。

You can change font property after show method(like showFromBarButtonItem) as below.

CGRect oldFrame = [(UILabel*)[[sheet subviews] objectAtIndex:0] frame];
UILabel *newTitle = [[[UILabel alloc] initWithFrame:oldFrame] autorelease];
newTitle.font = [UIFont boldSystemFontOfSize:17];
newTitle.textAlignment = UITextAlignmentCenter;
newTitle.backgroundColor = [UIColor clearColor];
newTitle.textColor = [UIColor whiteColor];
newTitle.text = @"My Title";
[sheet addSubview:newTitle];

[sheet release];
