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
clang: error: no such file or directory: '/Users/apple/Desktop/SigninViewController.m'
clang: error: no input files
