Question

我遇到了XCode的问题并且需要很快的帮助......我有一个plist文件，我需要访问它，它应该填充所有可用车辆的数组......不幸的是它没有这样做。 rootPath有一个值。 path有一个值。 settings NOT 有值，它返回为零。为什么是这样？据我所知，这曾经适用于旧版本的iOS / OS / XCode版本。任何想法都是完美的！以下是plist文件出错的代码：

    -(NSArray *)AllAvailableVehicles {
    // load in vehicles from plist data

    //NSString *path = [[NSBundle mainBundle] pathForResource:
    //                  @"vehicles" ofType:@"plist"];

    NSString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                                              NSUserDomainMask, YES) objectAtIndex:0];

    NSString *path = [rootPath stringByAppendingPathComponent:@"vehicles.plist"];

    NSDictionary *settings = [NSDictionary dictionaryWithContentsOfFile:path];

    NSArray *array = [settings objectForKey:@"Vehicles"];

    NSMutableArray *vehicleMutArray = [NSMutableArray arrayWithCapacity:20];
    for (NSDictionary *dict in array){
        Vehicle *vehicle = [[Vehicle alloc] init];
        vehicle.displayName = [dict objectForKey:@"Display Name"];
        vehicle.keyName = [dict objectForKey:@"Key Name"];
        vehicle.maxPassengers = [[dict objectForKey:@"Max Passengers"] intValue];
        vehicle.cabCode = [dict objectForKey:@"Cabmaster Code"];
        vehicle.luggageImage = [dict objectForKey:@"Image"];
        [vehicleMutArray addObject:vehicle];
        [vehicle release];
    }
    NSArray *vehiclesArray = [[vehicleMutArray copy] autorelease];
    return vehiclesArray;

}

Answer 1

替换

NSString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                                          NSUserDomainMask, YES) objectAtIndex:0];

NSString *path = [rootPath stringByAppendingPathComponent:@"vehicles.plist"];

与

NSString *path = [[NSBundle mainBundle] pathForResource:@"vehicles" ofType:@"plist"];

Answer 2

我已经解决了这个问题！事实证明我有一些构建规则，这意味着Plist文件不会复制，我删除了所有的构建规则，它的工作原理！

iOS - 未填充数组 - NSDictionary / NSArray
