把主要的代码先复制过来……
读Plist文件

　　NSString *errorDesc = nil;　　NSPropertyListFormat format;　　NSString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];　　NSString *plistPath = [rootPath stringByAppendingPathComponent:@"bookmarks.plist"];　　if (![[NSFileManager defaultManager] fileExistsAtPath:plistPath]) {　　plistPath = [[NSBundle mainBundle] pathForResource:@"bookmarks" ofType:@"plist"];　　}　　NSData *plistXML = [[NSFileManager defaultManager] contentsAtPath:plistPath];　　context.bookmarksDic = (NSMutableDictionary *)[[NSPropertyListSerialization propertyListFromData:plistXML mutabilityOption:NSPropertyListMutableContainersAndLeaves　　format:&format　　errorDescription:&errorDesc] retain];　　keysArr = [[[context.bookmarksDic allKeys] sortedArrayUsingSelector:@selector(compare:)] retain];　　if (!context.bookmarksDic) {　　NSLog(@"Error reading plist: %@, format: %d", errorDesc, format);　　}

写入Plist

Context *context = [Context getInstance];　　NSString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,　　NSUserDomainMask, YES) objectAtIndex:0];　　NSString *plistPath = [rootPath stringByAppendingPathComponent:@"bookmarks.plist"];　　NSString *error;　　NSData *plistData = [NSPropertyListSerialization dataFromPropertyList:context.bookmarksDic　　format:NSPropertyListXMLFormat_v1_0　　errorDescription:&error];　　if(plistData) {　　[plistData writeToFile:plistPath atomically:YES];　　}　　else {　　NSLog(@"%@",error);　　[error release];　　}
