计算label文字Size

直接上代码 直接copy 过去用吧.

- (CGSize)stringCGSizeWithString:(NSString *)stringText Font:(CGFloat)font

{

CGSize stringTextSize = [stringText boundingRectWithSize:CGSizeMake(self.view.frame.size.width, MAXFLOAT) options:NSStringDrawingUsesLineFragmentOrigin attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:font]} context:nil].size;

return stringTextSize;

}
