问题描述：
在己经测试好的工程中，加入了一个新的静态库target,该target编译完全正常没有报任何错。然后在另一个工程中使用生成的.a文件，编译我链接都没有任务错误，但是在调用静态库中定义的某些函数时，出现对象不能接受该消息的错程，导致程序崩掉。
用nm命令查看发现，生成的.a文件中的确没有这个函数：
nm /Users/yndfcd/Library/Developer/Xcode/DerivedData/Kline-enfzvyhrpqalelaiqkncnjkpgcau/Build/Products/Debug-iphonesimulator/libKlineView.a

另附上foo.h和klineview.h的定义：
//
// Foo.h
// Kline
//
// Created by yndfcd on 15/4/9.
//
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
#import “KlineView.h”
@interface Foo : NSObject
-(void)fooFunc1;
-(void)fooFunc2;
-(UIView*)creatKlineView:(CGRect)frame;
@end
//
// KlineView.h
// Kline
//
// Created by yndfcd on 15/3/27.
// Copyright (c) 2015年 BlueMobi. All rights reserved.
//
#import <UIKit/UIKit.h>
@interface KlineView : UIView
@property (nonatomic,strong) NSArray* rawData;
@property (nonatomic,assign) int startPos;
@property (nonatomic,assign) CGFloat segmentWidth;
@property (nonatomic,assign) CGFloat macdHeight;
@property (nonatomic,assign) CGFloat maHeight;
@property (nonatomic,assign) CGFloat diagramWidth;
@property (nonatomic,assign) CGFloat leading;
@property (nonatomic,assign) CGFloat top;
-(void)fetchData;
-(id) initWithFrame:(CGRect)frame;
@end
在foo.o中定义的函数调用均正常，包括返回一个UIView对象的那个方法，尝试在Foo中加一个方法返回一个KlineView类的对象仍然会崩掉，原因是KlineView不能接收initWithFrame消息。从上面nm打印的结果来看，KlineView的基类似乎是NSObject.
