我有一个可以玩不同类别的游戏。这些类别基本上是plist文件。所以,如果在将来,我想添加plists,用户应该能够下载一个plist并发挥新的水平。所以我的目标是:
这是我做的,它的工作原理(控制台日志“完成!!”),但是如果我检查文件是否在文件目录中,则没有响应(布尔文件存档保持为NO)。
-(void)startGame:(id)sender{
NSArray *categoriesArray = [[GameStateSingleton sharedMySingleton] categoriesArray];
NSString *category = [NSString stringWithFormat:[categoriesArray objectAtIndex:[sender tag]]];
NSString *thePath = [mainPath stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.plist",category]];
NSDictionary *categoryPlist = [NSDictionary dictionaryWithContentsOfFile:thePath];
if(categoryPlist != nil){
[[GameStateSingleton sharedMySingleton]setCurrentCategory:category];
[[GameStateSingleton sharedMySingleton]updateHexCountAndInitalTime];
[[CCDirector sharedDirector]replaceScene:[CCTransitionFade transitionWithDuration:TRANSITIONDURATION scene:[LevelSets scene]]];
}
else{
[self plistForCategory:category];
NSString* documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *myCategory= [documentsPath stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.plist",category]];
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:myCategory];
if(fileExists == YES){
[[GameStateSingleton sharedMySingleton]setCurrentCategory:category];
[[GameStateSingleton sharedMySingleton]updateHexCountAndInitalTime];
[[CCDirector sharedDirector]replaceScene:[CCTransitionFade transitionWithDuration:TRANSITIONDURATION scene:[LevelSets scene]]];
NSLog(@"category exists now");
}
}
}
-(void)plistForCategory:(NSString*)category
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSURL *url = [NSURL URLWithString:[ NSString stringWithFormat:@"http://www.tinycles.com/wannaplay/plists/%@.plist",category]];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDownloadDestinationPath:documentsDirectory];
[request setDelegate:self];
[request startAsynchronous];
}
- (void)requestFinished:(ASIHTTPRequest *)request
{
NSLog(@"finished !!");
}
- (void)requestFailed:(ASIHTTPRequest *)request
{
// Download failed. This is why.
NSError *error = [request error];
NSLog(@"%@", error);
}
答案 0 :(得分:0)
也许问题是因为你正在启动异步请求,所以如果请求还没有完成,你的if(fileExist==YES)
仍会返回NO;我建议你在这种情况下启动同步请求:
- (IBAction)startRequest:(id)sender
{
NSURL *url = [NSURL URLWithString:LINK_TO_PLIST];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDownloadDestinationPath:DOC_PATH];
[request startSynchronous];
NSError *error = [request error];
if (!error) {
//start your game after the file is downloaded
}
}
