如何使用（instancetype）arrayWithObjects：（id）？

Question

我正在嘗試使用此iOS功能

• +（實例類型）arrayWithObjects：（id）

我相信我將數組傳遞給它，但是我無法弄清楚如何訪問該數組，而且我不知道如何使用它。 我花了幾個小時試圖弄清楚...請幫助我！

+ (instancetype)arrayWithObjects:(id)[@"Starcraft", @"League of Legends", @"Starcraft 2", @"World of Warcraft",
@"The Sims", @"Icewind Dale", @"Shadowbane", @"Grand Theft Auto 3", @"Pac Man", @"Astroids",
@"Grand Theft Auto 4", @"Grand Theft Auto 5", @"MineCraft", @"Mass Effect", @"Mass Effect 2",
@"Mass Effect 3", @"Dragon Age", @"The Sims 2", @"The Sims 3", @"Rockband", @"Rockband 2",
@"Rockband 3", @"Dragon Age 2", @"The Witcher", @"The Witcher 2", @"Plants vs Zombies",
nil]
{
    return [[[self class] alloc] init];
}

Answer 1

這是您真正想要的，如果您想要對象的整個數組而不是原來具有單個數組的數組。

NSArray* array = [NSArray arrayWithObjects:@"Starcraft", @"League of Legends", @"Starcraft 2", @"World of Warcraft",
@"The Sims", @"Icewind Dale", @"Shadowbane", @"Grand Theft Auto 3", @"Pac Man", @"Astroids",
@"Grand Theft Auto 4", @"Grand Theft Auto 5", @"MineCraft", @"Mass Effect", @"Mass Effect 2",
@"Mass Effect 3", @"Dragon Age", @"The Sims 2", @"The Sims 3", @"Rockband", @"Rockband 2",
@"Rockband 3", @"Dragon Age 2", @"The Witcher", @"The Witcher 2", @"Plants vs Zombies",
nil];

它會在運行時創建一個以nil結尾的給定字符串的NSArray，以指示結尾。
