推荐答案

你应该使用 NSAttributedString 和 NSKernAttributeName 属性

以下是一个小例子：

UILabel *label = [[UILabel alloc] initWithFrame:self.view.bounds];

NSString *string = @"Some important text";
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:string];

float spacing = 5.0f;
[attributedString addAttribute:NSKernAttributeName
            value:@(spacing)
            range:NSMakeRange(0, [string length])];

label.attributedText = attributedString;
[self.view addSubview:label];
