1.Invalid parameter not satisfying: [views count] == 3

用到这个函数的时候，报了这个错，后来animated改为no就好了，查的显示，动画会引起奔溃

[self.pageViewController setViewControllers:@[_controllers[_currentTypeIndex]]

direction:UIPageViewControllerNavigationDirectionForward

animated:NO

completion:nil];

2.16.5.19  'NSInternalInconsistencyException', reason: 'UITableView (; layer =; contentOffset: {0, 0}; contentSize: {375, 415}>) failed to obtain a cell from its dataSource ()' 

原因:没有在调用之前注册    ps:快一个月没写代码了,手生了........

解决办法先注册cell才可以:[mTable registerNib:[UINib nibWithNibName:TESTIMAGECELL bundle:nil] forCellReuseIdentifier:TESTIMAGECELL];\

2.16.5.19  Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'table view row height must not be negative - provided height for index path ({length = 2, path = 0 - 1}) is nan'

我返回了一个nan,非整数,所以崩了

3.u3d项目打包到xcode

ld: warning: ignoring file /Users/apple/Desktop/iosU3dPro_test/Libraries/libiPhone-lib.a, file was built for archive which is not the architecture being linked (i386): /Users/apple/Desktop/iosU3dPro_test/Libraries/libiPhone-lib.a

Undefined symbols for architecture i386:

解决办法：1.u3项目直接运行在xcode上  ，不要用模拟器，选择真机

2.如果非要使用模拟器，用如下方法（第一次需要以后就不用了）

3.上面的问题（这种问题多发于拿到不适自己的项目）

"_OBJC_CLASS_$_ALAssetsLibrary", referenced from:

objc-class-ref in OAlbumController.o

可能情况有两种：

1>OAlbumController.m  类没有添加  需要在build phases->complile sources查看是否有，没有就添加下

2>查看ALAssetsLibrary类使用时需要的框架是不是都添加了，可以百度下需要的框架，然后在build phases－>link binary with libraries  里面检查是否缺失

4.2016.8.17  我又开始做项目了
