我正在编写一款iPhone游戏,并且能够很好地处理硬编码的水平数据,但我希望将水平数据存储在plist中并在启动时加载它.我从来没有使用过plists,也很难理解我应该如何根据我的数据模型设置plist.
@H_404_8@
这是我现在硬编码的方式：@H_404_8@
(在我的appDelegate中)@H_404_8@
@H_404_8@
- (void)loadLevels {
//setup NSNumber objects to load into sequences
NSNumber * rID = [[[NSNumber alloc] initWithInt:0] autorelease];
NSNumber * bID = [[[NSNumber alloc] initWithInt:1] autorelease];
NSNumber * gID = [[[NSNumber alloc] initWithInt:2] autorelease];
NSNumber * yID = [[[NSNumber alloc] initWithInt:3] autorelease];
NSNumber * rbID = [[[NSNumber alloc] initWithInt:4] autorelease];
NSNumber * rgID = [[[NSNumber alloc] initWithInt:5] autorelease];
NSNumber * ryID = [[[NSNumber alloc] initWithInt:6] autorelease];
NSNumber * bgID = [[[NSNumber alloc] initWithInt:7] autorelease];
NSNumber * byID = [[[NSNumber alloc] initWithInt:8] autorelease];
NSNumber * gyID = [[[NSNumber alloc] initWithInt:9] autorelease];
//Level One's Sequence
NSMutableArray * aSequence = [[[NSMutableArray alloc] initWithCapacity:1] autorelease];
[aSequence addObject: rID];
[aSequence addObject: bID];
[aSequence addObject: gID];
[aSequence addObject: yID];
[aSequence addObject: rbID];
[aSequence addObject: rgID];
[aSequence addObject: ryID];
[aSequence addObject: bgID];
[aSequence addObject: byID];
[aSequence addObject: gyID];
// Load level One
_levels = [[[NSMutableArray alloc] init] autorelease];
Level *level1 = [[[Level alloc] initWithLevelNum:1 levelSpeed:1.0 levelSequence:aSequence] autorelease];
[_levels addObject:level1];
//do the same thing for subsequent levels//
}
(这就是我实现Level Level的方法)@H_404_8@
@H_404_8@
#import "Level.h"
@implementation Level
@synthesize levelNum = _levelNum;
@synthesize levelSpeed = _levelSpeed;
@synthesize levelSequence = _levelSequence;
- (id)initWithLevelNum:(int)levelNum levelSpeed:(float)levelSpeed levelSequence:(NSMutableArray *)levelSequence {
if ((self = [super init])) {
self.levelNum = levelNum;
self.levelSpeed = levelSpeed;
self.levelSequence = [[[NSMutableArray alloc] initWithArray:levelSequence] autorelease];
}
return self;
}
- (void)dealloc {
[_levelSequence release];
_levelSequence = nil;
[super dealloc];
}

我只是没有得到如何设置一个plist来存储我的数据以匹配我的模型.请问有人可以给我一些建议吗？@H_404_8@
加成：
(这是我认为我需要设置plist的方式 – 数据模型只是初始化我的级别的三个变量(上图).如果你查看我当前的plist,可能会更清楚它是如何设置的,但是每个级别都包含在内of：级别编号,级别速度和表示该级别所需序列的数字数组.)@H_404_8@
现在,如果我确实有正确的设置,我如何将值加载到我的程序中？@H_404_8@
解决方法
>将plist文件添加为项目中的资源文件.说,它的名字是config.plist
>获取资源文件的路径. (但是,请注意[NSBundle mainBundle],因为它不会在单元测试中返回单元测试包.)
>获取资源文件的路径. (但是,请注意[NSBundle mainBundle],因为它不会在单元测试中返回单元测试包.)
@H_404_8@
NSString *plistPath = [[NSBundle mainBundle] pathForResource:@"config" ofType:@"plist"];
>您的根对象是一个级别数组.将其加载到NSArray中.@H_404_8@
// this is autoreleased. you can retain it if needed NSArray *levelArray = [NSArray arrayWithContentsOfFile:plistPath];
>现在你有了一系列关卡.每个级别都是字典.加载级别i(从0开始计数).@H_404_8@
NSDictionary *level = [levelArray objectAtIndex:i];
>现在,您可以使用objectForKey方法从级别字典中获取对象.例如,要获取序列数组：@H_404_8@
NSArray *seq = [level objectForKey:@"levelSequence"];
