如何在iphone应用程序中设置UIFont粗体

Question

我想设置的字体UILabel,以黑体加粗,但它只是显示正常字体.

我正在使用下面的代码

UILabel *labelHeadingOne = [[UILabel alloc] initWithFrame:CGRectMake(22,260, 504, 20)];
labelHeadingOne.backgroundColor = [UIColor clearColor];

labelHeadingOne.font=[UIFont fontWithName:@"Helvetica" size:16];

labelHeadingOne.text=@"Pre-emergent herbicide with residual control for warm-season turf";

Answer 1

您可以使用字体名称Helvetica-Bold.查看http://iosfonts.com/获取完整列表.

Answer 2

用这个 :

  labelHeadingOne.font=[UIFont fontWithName:@"Helvetica-Bold" size:16];
