在Objective-C逗号分隔字符串的NSArray [英] Comma-separated string to NSArray in Objective-C

问题描述

所以我有数组没有经验......但我需要用一个来填充一个UIPickerView。我获得通过HTTP（NSURLConnection的）对象的列表。这工作得很好。目前，响应存储在一个的NSString作为一个逗号分隔的列表。我需要将其转换为一个数组。我觉得这是数组的我需要的类型：

So I have no experience with arrays... But I need to use one to populate a UIPickerView. I am obtaining a list of objects via HTTP (NSURLConnection). This works fine. Currently, the response is stored in a NSString as a comma-separated list. I need to convert it to an array. I think this is the type of array I need:

NSArray  * myArray2 = [NSArray arrayWithObjects:@"foo",@"bar",@"baz",nil];

也许我过于复杂的事情......我真的不知道。目前已为PickerView一个数组，我有这样的设置将项目添加到PickerView阵列我用这个code：

Maybe I'm overcomplicating things... I'm really not sure. There is already an array for the PickerView, and I have it setup so to add an item to the PickerView array I use this code:

[pickerArray addObject:@"Item 1"];

所以...我如何在一个逗号分隔的字符串（第1项，第2项，第3项，...）到单独的数组项分隔这些项目（[pickerArray ADDOBJECT：@项目1];） ??

So... How do I separate the items in a comma-separated string (item 1,item 2,item 3,...) into separate array items ([pickerArray addObject:@"item 1"];)??

推荐答案

假设没有关于转义/包含反向转义的字符串中的逗号担心，它应该是这个简单的：

Assuming there's no worry about escaping/unescaping commas contained within the strings, it should be this simple:

NSArray *items = [theString componentsSeparatedByString:@","];
