Object－C文件的读写

NSArray *array = [NSArray arrayWithObjects:@"Foo", [NSNumber numberWithBool:YES],[NSDate dateWithTimeIntervalSinceNow:60],nil];
[array writeToFile:@"MyArray.plist" atomically:YES];
NSLog(@"file is writed success!");

NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:@"Dingdongxia",@"Name",[NSNumber numberWithInt:36],@"Age", nil];
[dict writeToFile:@"MyDict.plist" atomically:YES];

NSDictionary *dict1 = [NSDictionary dictionaryWithObjectsAndKeys:
@"Sam",@"Name",
@"Male",@"Sex",
[NSNumber numberWithInt:36],@"Age",
@"dingdongxia@163.com",@"Email",
@"www.dingdongxia.com",@"Websit",
nil];

if ([dict1 writeToFile:@"Sam" atomically:YES]==NO) {
NSLog(@"make xml is fail!");
}

//读文件
NSDictionary *dict1_read = [NSDictionary dictionaryWithContentsOfFile:@"Sam"];
for (NSString *key in dict1_read) {
NSLog(@"%@:%@",key,[dict1_read objectForKey:key]);
}

运行结果如下：

2015-07-27 15:28:40.140 test[634:19716] file is writed success!
