计算label宽度和高度 - iOS

用到了，记录下

NSArray * labelArray = @[@"天苍苍",@"明日依山尽",@"老夫聊发少年狂",@"左牵黄右擒苍锦帽貂裘哈哈哈"];

for (int i = 0; i < labelArray.count; i++) {
    UILabel  *label = [UILabel new];

    label.font = [UIFont systemFontOfSize:11];
    label.text = labelArray[i];
    [self.view addSubview:label];
    CGSize size = [labelArray[i] sizeWithAttributes:@{NSFontAttributeName: [UIFont systemFontOfSize:11.0f]}];
    NSLog(@"==第%d个===%f===%f",i,size.width,size.height);
}
