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];

}
