京贝debug
1.Safe Area Layout Guide before iOS 9.0
设置不用
2.Multiple commands produce
iphoneos/NoteBook.app/.gitkeep’
在buildsetting删掉这些文件
3.Build input file cannot be found: /NoteBook.pch
实际文件不在这个位置
4.duplicate symbol for architecture x86_64
删除重复添加的文件
5.Undefined symbol: _OBJC_CLASS_$_CellModel
没有实现文件,只有头文件
6.不用一下子把很多cell都拉进去
7.Could not find a storyboard named ‘Main’ in bundle NSBundle
8.Terminating app due to uncaught exception ‘Bad property protocol declaration’, reason: ‘ is not allowed JSONModel property protocol, and not a JSONModel class.
类没实现
9‘NSInvalidArgumentException’, reason: ‘\* -[__NSArrayM insertObject:atIndex:]: object cannot be nil’**
空对象
10.JSON转的模型部分为空:key写错了.
11.Terminating app due to uncaught exception ‘NSInternalInconsistencyException’, reason: ‘could not dequeue a view of kind: UICollectionElementKindCell with identifier HYBannerCellID - must register a nib or a class for the identifier or connect a prototype cell in a storyboard’
12.does not have a reuseIdentifier - cells must be retrieved by calling -dequeueReusableCellWithReuseIdentifier:forIndexPath:’
13.‘the cell returned from -collectionView:cellForItemAtIndexPath: does not have a reuseIdentifier - cells must be retrieved by calling -dequeueReusableCellWithReuseIdentifier:forIndexPath:’
14.banner图片显示不出来
15.数据为空,首先检查字符串
16.’Bad property protocol declaration’, reason: ‘ is not allowed JSONModel property protocol, and not a JSONModel class.’
16.itemForIndex 中用masonry
NSInternalInconsistencyException’, reason: ‘attempting to add unsupported attribute: <DCHandPickViewController: 0x101f39670>’
17.index 0 beyond bounds for empty array’
没初始化homeViewModel
18.‘the view returned from -collectionView:viewForSupplementaryElementOfKind:atIndexPath (UICollectionElementKindSectionFooter,<NSIndexPath: 0xca82a82eec4d21d1> {length = 2, path = 0 - 0}) was not retrieved by calling -dequeueReusableSupplementaryViewOfKind:withReuseIdentifier:forIndexPath: or is nil
因为返回高度给已删除的footer
19.Masonry导致卡顿,多余的constraints.
20.6 duplicate symbols for architecture arm64
复制的文件没删除
21.增加了数据后滚动后不见了,因为是重新处理的图的原因.
22.collect没数据,先看数据源
23.‘NSInvalidArgumentException’, reason: ‘\* -[__NSArrayM insertObject:atIndex:]: object cannot be nil’**
把 字典写成了对象.
24.‘-[__NSDictionaryM name]: unrecognized selector sent to instance 0x280ae28e0’
25NSRangeException’, reason: ‘\* -[__NSArrayM objectAtIndexedSubscript:]: index 0 beyond bounds for empty array’**
26__NSArrayM objectAtIndexedSubscript:]: index 0 beyond bounds for empty array’
跟加载无关,是有的数据没有
27.内存耗用大.因为图片多
28.masonry导致卡顿.也许要分两个section,或者重新定义个cell(搞定).
29空白
1 | CGFloat top = 24; //XMGTitilesViewY; |
30.导入错了info.plist,导致错误:删除building,phase,info
Multiple commands produce /Info.plist’:
31.pch文件在Xcode新版本里需要手动添加,路径要写全
32.UIImageRenderingModeAlwaysOriginal导致图片显示不出来

34.Use of undeclared identifier ‘AFHTTPRequestOperationManager’
现在都用的是NSURLSession了，AFN中用的是AFHTTPSessionManager了~~
35.‘UICollectionView must be initialized with a non-nil layout parameter’
要在init里注册
36.标签没字,要看赋值那里是不是有问题
尤其第一个显示了最后一个,可能就是全都赋给了第一个.
37.nearby顶部label没显示,看看加没加
38.nearby顶部label显示模糊图片,两个label,添加了两次,而且没对齐.
39.nearby顶部titlebuttons,没走到就变红,走完了还不变回白色.
设isShaping关闭好了
40.nearby 底部多出一条白线,黑白都有.
1 | self.contentScrollView.frame = CGRectMake(0, tY + tH + bD, ScreenW, ScreenH - (tY + tH + bD) + 2); |
41.data parameter is nil’
文件名没写对
42.‘NSInternalInconsistencyException’, reason: ‘Delegate must respond to locationManager:didFailWithError:’
43.滑动起来总是距离就刷没了
把计算的距离放在模型里存起来
44.行间有灰色空白
1 | layout.minimumLineSpacing = 0; |
45.Undefined symbol: ___gxx_personality_v0
46.字典数组数据取不到,看key是否写错了
47.只显示左侧不显示右侧,cell内部坐标用cell.bounds
48.dequeueReusableSupplementaryViewOfKind:UICollectionElementKindSectionHeader
+[DCDeatilCustomHeadView length]: unrecognized selector sent to class 0x10469bfa8’
49NSInvalidArgumentException’, reason: ‘\* -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[0]’**
发通知的通知名写错
50DYGLInitPlatform] connection to host has failed: Error Domain=NSPOSIXErrorDomain Code=2 “No such file or directory”
51.启动图片失效.
52. JSONModel,字典数组可以不是mutable
NSMutableDictionary *dict2 = [content objectForKey:@”storeInfo”]; dict2是nil,
53.Property type of MR_StoreInfo.shortName is not supported by JSONModel.’
54.转模型为nil,搞了半天找到了工具.其实是局部变量的原因.
55.NSSring longlongValue,null设成了NSUInteger,改为了string
56.-[MR_SectionMenuFooter _setReuseIdentifier:] refactor导致
57.Cannot remove an observer
<MR_StoreInfoFirstCollectionViewCell 0x11653afb0> for the key path “distanceStr” from <MR_StoreInfo 0x101779ea0> because it is not registered as an observer.’
58.[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[0]’
59.-[__NSArrayM objectAtIndexedSubscript:]: index 7 beyond bounds [0 .. 3]’
60.-[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[0]’
