IOS根据文字计算laber的行数与长度

计算行数

CGFloat labelHeight = [self.content sizeThatFits:CGSizeMake(self.content.frame.size.width, MAXFLOAT)].height;

 NSNumber *count = @((labelHeight) / self.content.font.lineHeight);

计算长度

- (CGSize)getSizeRectMakeText:(NSString *)type addTextSize:(CGSize)text addFontDic:(NSDictionary *)dic{

    CGRect temp = [type boundingRectWithSize:text options:NSStringDrawingUsesLineFragmentOrigin attributes:dic context:nil];

    return temp.size;

}
