ios - UILabel : how do you set the font size?

Question

如何从 UILabel 设置字体大小？

我的代码:

UILabel *myView = [[UILabel alloc] initWithFrame:RectFrame];
[myView setBackgroundColor:[UIColor blueColor]];
[myView setText:[NSString stringWithFormat:@" A"]];
[myView setFont:[12] ]; <--- Error
[self.view addSubview:myView];

Answer 1

[myView setFont:[UIFont systemFontOfSize:12]];

或

[myView setFont:[UIFont boldSystemFontOfSize:12]];

或用于字体系列

[myView setFont:[UIFont fontWithName:@"Helvetica" size:12]];
