Question

我需要用一些案文来补充一下。重新计算的规模是固定的。

我行使以下职能:

- (void)drawText:(NSString *)text onView:(UIView *)view inRect:(CGRect)rect
{
    UILabel *lbl = [[UILabel alloc] initWithFrame:rect];
    lbl.minimumFontSize = 1;
    lbl.font = [UIFont systemFontOfSize:30];
    [lbl setText:text];
    lbl.adjustsFontSizeToFitWidth = YES;
    [view addSubview:lbl];
    [lbl release];
}

接着,我写了类似的内容:

[self drawText:@"Asdfghjkl;" onView:view inRect:CGRectMake(45, 40, 85, 13)];
[self drawText:@"qwertyui" onView:view inRect:CGRectMake(173, 31, 126, 22)];

我拿到了截断的文本。我的错误在哪里?

Answer 1

I think the main trouble is that some text fits width only but it must fit both width and height. So the fastest solution for me is to make a bigger transparent UILabel and put a text inside it using alignment

Answer 2

正如加戈莱夫所说,它将根据适当的宽度调整 only/em>。

因此,你应选择合适的体格,以适应你再次提供的高度。

如果不事先知道你会再次使用这个词,那么简单的解决办法是:

UILabel *label = [[UILabel alloc] initWithFrame:myView.bounds]; label.font = [UIFont fontWithName:@"Helvetica" size:1.f]; float fontAspectFactor = 1.f/label.font.lineHeight; label.font = [UIFont fontWithName:@"Helvetica" size:myView.height*fontAspectFactor]; [myView addSubview:label];
