NSString *path=[paths objectAtIndex:0];
NSLog(@"path = %@",path);
NSString *filename=[path stringByAppendingPathComponent:@"test.plist"];
NSFileManager* fm = [NSFileManager defaultManager];
[fm createFileAtPath:filename contents:nil attributes:nil];
//NSDictionary* dic = [NSDictionary dictionaryWithContentsOfFile:plistPath];

//创建一个dic，写到plist文件里
NSDictionary* dic = [NSDictionary dictionaryWithObjectsAndKeys:@"sina",@"1",@"163",@"2",nil];
[dic writeToFile:filename atomically:YES];
