3.iPhone书架中加载本地网页

（1）利用page= [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"iphone/baobaoweiyang"];函数来进行逐个判断和读取。

（2）将各个书籍网页的首页地址写入.plist文件中，然后读取.plist文件，并将读取处理封装成一个DM类。

本文上述采用的是方法（1），下边来讲述方法（2）：

DM.h

#import <Foundation/Foundation.h>

@interface DM : NSObject
{
        NSString *csurl;
	NSArray *tbc;
	NSInteger netref;
    
}

@property (nonatomic, retain) NSString *csurl;
@property (nonatomic, retain) NSArray *tbc;


+ (DM *)getInstance;

- (NSString *)getTabBarViewURL:(NSInteger)index;
- (NSInteger)getTabBarItemNumber;

@end
