Question

so I m making an iphone app, which needs to download a .plist from a server...

我知道如何制造和洗 to,并用一盘点文件做任何事情,但只是为我下载。

I ve tried using this code

NSMutableArray *profileArray;
profileArray = [[NSMutableArray Alloc] initWithContentsOfUrl:@"myurl.plist"];

but it always comes back with a (null) value, what should I do?

预收:D

Answer 1

InitWithContentsOfUrl: 方法将NSURL物体作为参数。你们需要像你那样,制造一只NSURL物体:

NSURL *url = [NSURL URLWithString: @"myurl.plist"];

then use this to instantiate the array:

NSMutableArray *profileArray; profileArray = [[NSMutableArray Alloc] initWithContentsOfUrl: url];
