iPhone读取和写入plist文件
plist文件是标准的xml文件，在cocoa中可以很简单地使用。这里介绍一下使用方法：
以下代码在Mac和iPhone中均适用。
?
写入plist文件：
NSMutableDictionary?*??dict?=??[??[??NSMutableDictionary??alloc??]??initWithContentsOfFile?:@"/Sample.plist"??]?;[??dict?setObject?:?@"Yes"??forKey?:?@"RestartSpringBoard"??]?;[??dict?writeToFile?:?@"/Sample.plist"??atomically?:?YES??]?;
?
读取plist文件：
NSMutableDictionary?*??dict?=???[??[??NSMutableDictionary??alloc??]??initWithContentsOfFile?:@"/Sample.plist"??]?;NSString?*??object??=??[??dict?objectForKey?:?@"RestartSpringBoard"??]?;
//读plist 文件?
到 NSMutableDictionary 中
????
??? dictplist = [[NSMutableDictionary alloc ] initWithContentsOfURL:[NSURL fileURLWithPath:path]];
??? [dictplist setObject:@"testOne" forKey:@"key1"];
??? NSLog([dictplist objectForKey:@"key1"]);
????
??? NSArray *array = [[NSArray alloc] initWithObjects:@"item1",@"item2",@"item3",nil];
??? [dictplist setObject:array forKey:@"arrayitemtest"];
????
??? [dictplist writeToFile:plistPath atomically:YES];
????
??? NSString *name = [dictplist objectForKey:@"name" ];
??? NSLog(name);
????
??? arraylist = [[NSMutableArray alloc] initWithArray:[dictplist objectForKey:@"arrayitemtest"]];
????
????
??? //从NSMutableDictionary 中构建 plist 文件?
??? ?
??? NSArray *array = [[NSArray alloc] initWithObjects:@"item1",@"item2",@"item3",nil];
??? ?dictplist = [[NSMutableDictionary alloc ] init];
??? [dictplist setObject:@"nameOne" forKey:@"name"];
????
??? [dictplist setObject:array forKey:@"item"];
??? ?
??? [dictplist writeToFile:plistPath atomically:YES];
??? ?//arraylist = [[NSMutableArray alloc] init];
??? //[arraylist addObject:[dictplist objectForKey:@"name"]];
????
??? arraylist = [[NSMutableArray alloc] initWithArray:[dictplist objectForKey:@"item"]];
