现在在用storyboard拖拉界面。

1.崩溃 PassengerAcountViewController 0x7fdb78c29ed0> setValue:forUndefinedKey:]: this class is not key .....

http://q.cnblogs.com/q/36577/,忘记删除了storyboard里面的链接

2.push 不进去问题

解决方法:

添加约束文章

storyboard 添加tableview问题

1.协议方法不走 tableview的datesource和delegate 没有和控制器关联（在控制器里写代码貌似不好用）

UIView提供了大量管理视图的方法

//加一个视图到一个视图里面
addSubview:
//将一个视图移到前面
bringSubviewToFront:
//将一个视图推送到背后
sendSubviewToBack:
//把视图移除
removeFromSuperview
//插入视图并指定索引
insertSubview:atIndex:
//插入视图在某个视图之上
insertSubview:aboveSubview:
//插入视图在某个视图之下
insertSubview:belowSubview:
//交换两个位置索引的视图
exchangeSubviewAtIndex:withSubviewAtIndex:

建立UIView动画块

CGContextRef context = UIGraphicsGetCurrentContext();
//标记动画开始
[UIView beginAnimations:nil context:context];
//定义动画加速或减速的方式
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
//定义动画的时长 1秒
[UIView setAnimationDuration:1.0];
//中间处理位置变化，大小变化，旋转，等等的
[[self.view viewWithTag:999] setAlpha:1.0f];
//标志动画块结束
[UIView commitAnimations];
//还可以设置回调
[UIView setAnimationDelegate:self];
//设置回调调用的方法
[UIView setAnimationDidStopSelector:@selector(animationFinished:)];

使用storyboard 报错

property's synthesized getter follows Cocoa naming convention for returning 'owned' objects

You own any object you create

You create an object using a method whose name begins with “alloc”, “new”, “copy”, or “mutableCopy” (for example, alloc, newObject, or mutableCopy).

一定要注意命名规范，不能以alloc，new，copy，mutableCopy 作为开头命名，比如：newPassword,

iOS -[__NSCFConstantString size]: unrecognized selector sent to instance 0x10227a9c8

[__NSCFConstantString size]: unrecognized selector sent to instance 错误

因为使用时候的类型和初始化的对象类型不匹配造成的

提取本地json

NSData * data=[ NSData dataWithContentsOfFile :[[ NSBundle mainBundle ]
pathForResource : @"localobj"

ofType:@"json"]];

NSError* error;

NSDictionary *localObj =[ NSJSONSerialization JSONObjectWithData :data

options : NSJSONReadingMutableContainers

error:&error];

UIGestureRecognizer是一个抽象类，定义了所有手势的基本行为，使用它的子类才能处理具体的手势。
