ios - 如何设置绘图文本的Arial字体样式

Question

我使用下一个代码来创建一个 png 文件。我需要用 Arial 24 写一些文字。我该怎么做？我找不到在哪里可以设置 Arial 字体样式。

UIImage *image = [BSSharedObject getInstance].downloadedImage;
    UILabel *label = [[UILabel alloc]init];
    UIFont *font = [UIFont systemFontOfSize:24.0];


UIGraphicsBeginImageContextWithOptions(CGSizeMake(WIDTH, HEIGHT), NO, 1.0);
[message drawInRect:CGRectMake(INDENT, INDENT, WIDTH - 2 *INDENT ,600) withFont:font lineBreakMode:UILineBreakModeWordWrap alignment:UITextAlignmentLeft];
[image drawInRect:CGRectMake((WIDTH - INDENT - image.size.width), (HEIGHT - INDENT- image.size.height), image.size.width, image.size.height)];
UIImage *resultImage  = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

[BSSharedObject getInstance].createdImage = resultImage;

UIImage *im =  [BSSharedObject getInstance].createdImage;
return resultImage;

Answer 1

[UIFont fontWithName:@"Arial"size:24]

这将为您提供所需的字体。调用 systemFontOfSize 可以预见会返回 system 字体 - 在 iOS 中，您会得到 Helvetica Neue。
