将2个数组合并为一个数组

Question

我正在使用RestKit获得2个独立API的.我得到的API只是罚款,但我需要把二者结合起来arrays转换一个array.

我该怎么做？这是我的代码,将根据需要发布额外的内容,谢谢! (NSMutableArray *array是array这将是组合hArray和iArray)

ViewController.m

@property (strong, nonatomic) NSArray *hArray;
@property (strong, nonatomic) NSMutableArray *array;
@property (strong, nonatomic) NSArray *iArray;


[[RKObjectManager sharedManager] loadObjectsAtResourcePath:
[NSString stringWithFormat:@"/n/?limit=200&l=%@&t=%@&apikey=111", 
lAbbreviation, tID] usingBlock:^(RKObjectLoader *loader) {
        loader.onDidLoadObjects = ^(NSArray *objects){
            hArray = objects;
            [_tableView reloadData];
        };
        [loader.mappingProvider setMapping:[F mapping] forKeyPath:@"f"];
        loader.onDidLoadResponse = ^(RKResponse *response){
        };
    }];

    [self.iObjectManager loadObjectsAtResourcePath:
    [NSString stringWithFormat:@"/u/?client_id=111"] 
    usingBlock:^(RKObjectLoader *loader) {
        loader.onDidLoadObjects = ^(NSArray *oI){
            iArray = oI;
            [_tableView reloadData];
        };
        [loader.mappingProvider setMapping:[Data mapping] forKeyPath:@"data"];
        loader.onDidLoadResponse = ^(RKResponse *response){
        };
    }];

它应该像写作一样简单:

array = [NSMutableArray array];
[array addObjectsFromArray:hArray];
[array addObjectsFromArray:iArray];

为了更具体地说明您的示例,以下是编辑代码的方法:

@property (strong, nonatomic) NSArray *hArray;
@property (strong, nonatomic) NSMutableArray *array;
@property (strong, nonatomic) NSArray *iArray;

array = [NSMutableArray array]; // new line

[[RKObjectManager sharedManager] loadObjectsAtResourcePath:
[NSString stringWithFormat:@"/n/?limit=200&l=%@&t=%@&apikey=111", 
lAbbreviation, tID] usingBlock:^(RKObjectLoader *loader) {
    loader.onDidLoadObjects = ^(NSArray *objects){
        hArray = objects;
        [array addObjectsFromArray:hArray]; // new line
        [_tableView reloadData];
    };
    [loader.mappingProvider setMapping:[F mapping] forKeyPath:@"f"];
    loader.onDidLoadResponse = ^(RKResponse *response){
    };
}];

[self.iObjectManager loadObjectsAtResourcePath:
[NSString stringWithFormat:@"/u/?client_id=111"] 
usingBlock:^(RKObjectLoader *loader) {
    loader.onDidLoadObjects = ^(NSArray *oI){
        iArray = oI;
        [array addObjectsFromArray:iArray]; // new line
        [_tableView reloadData];
    };
    [loader.mappingProvider setMapping:[Data mapping] forKeyPath:@"data"];
    loader.onDidLoadResponse = ^(RKResponse *response){
    };
}];

为清楚起见,我使用了// new line我添加的每一行中的注释.

注意:如果您将iArray和hArray用作临时值,则还可以避免声明这两个属性.
