给UILabel 设置行间距

在UILabel设置多行

self.titleL.numberOfLines = 0

为了美观, 需求要求有一定的行间距.

-(NSMutableAttributedString * ) getTextStringLineSpace:(NSString *) string lineSpace:(CGFloat)space{

NSMutableAttributedString * attributedString1 = [[NSMutableAttributedString alloc] initWithString:string];
NSMutableParagraphStyle * paragraphStyle1 = [[NSMutableParagraphStyle alloc] init];
[paragraphStyle1 setLineSpacing:space];
[attributedString1 addAttribute:NSParagraphStyleAttributeName value:paragraphStyle1 range:NSMakeRange(0, [string length])];

return attributedString1;

}

调用此方法即可.

[self.titleL setAttributedText:[string getTextStringLineSpace:string lineSpace:3]];
