日常报错收集记录

1.LGAlertView库viewWillTransitionToSize崩溃

- (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator {
    [super viewWillTransitionToSize:size withTransitionCoordinator:coordinator];

      __weak typeof(self) weakSelf = self;
   dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
        [UIView animateWithDuration:coordinator.transitionDuration animations:^{
            [self setNeedsStatusBarAppearanceUpdate];
            [self.alertView layoutValidateWithSize:size];
        }];
    });
}

-[_UIViewControllerOneToOneTransitionContext _duration]: message sent to deallocated instance

po coordinator.transitionDuration输出 error: property 'transitionDuration' not found on object of type 'id'

解决方法：

使用硬编码的持续时间，pod 'LGAlertView'更改为vovnit的派生库

pod 'LGAlertView', :git => 'https://github.com/vovnit/LGAlertView.git'

vovnit的派生库的具体解决方案

@vovnit的具体解决方式如下：

- (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator {
    if (coordinator) {
        [super viewWillTransitionToSize:size withTransitionCoordinator:coordinator];
    }
    
    @try {
        [[NSOperationQueue mainQueue] addOperationWithBlock:^{
            __weak typeof(self) weakSelf = self;
            [UIView animateWithDuration:0.5 animations:^{
                if (weakSelf) {
                    if ([weakSelf respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]) {
                        [weakSelf setNeedsStatusBarAppearanceUpdate];
                    }
                    if (weakSelf.alertView) {
                        [weakSelf.alertView layoutValidateWithSize:size];
                    }
                }
            }];
        }];
    } @catch (NSException *exception) {
        //
    } @finally {
        //
    }
}

2. Name types using UpperCamelCase.

骆驼拼写法

在单次底部有波浪线提示Typo: In word ''时，是由于未按照骆驼拼写法进行定义，一般是单词拼写错误了。如：

class RandowWords extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final wordPair = new WordPair.random();

    return Padding(
        padding: const EdgeInsets.all(8.0),
      child: new Text('随机字符串：${wordPair.toString()}'),
    );
  }
}

RandowWords底部会提示Typo:In word 'Randow'；此时是由于“随机”单词拼写错误，修改为Random就可以了。

3. hexo 报错

hexo s
ERROR Cannot find module 'hexo' from '/Users/pv/myBlog/blog'
ERROR Local hexo loading failed in ~/myBlog/blog
ERROR Try running: 'rm -rf node_modules && npm install --force'

只需要运行以下命令安装下就可以了

npm install hexo-util --save
