Split up NSString using a comma
提问by Adam Storr
I have a JSON feed connected to my app. One of the items is lat & long separated by a comma. For example: "32.0235, 1.345".
我有一个连接到我的应用程序的 JSON 提要。其中一项是经纬度，以逗号分隔。例如：“32.0235、1.345”。
I'm trying to split this up into two separate values by splitting at the comma.
我试图通过在逗号处拆分来将其拆分为两个单独的值。
Any advice? Thanks!!
有什么建议吗？谢谢！！

NSArray *strings = [coords componentsSeparatedByString:@","];

NSString* myString = @"32.0235, 1.345".
NSArray* myArray = [myString componentsSeparatedByString:@","];
NSString* firstString = [myArray objectAtIndex:0];
NSString* secondString = [myArray objectAtIndex:1];
See in documentation
见文档

You want:
你要：
- (NSArray *)componentsSeparatedByString:(NSString *)separator
- (NSArray *)componentsSeparatedByString:(NSString *)separator
using @"," as separator.
使用@"," 作为分隔符。

This is work for me as I was not looking to define any Array.
这对我有用，因为我不想定义任何数组。
NSString* firstString = [[myString componentsSeparatedByString:@","] objectAtIndex:0];

Try [yourCommaSeparatedString componentsSeparatedByString:@", "]
that will give a NSArray with strings you can then call floatValue on ;)
尝试[yourCommaSeparatedString componentsSeparatedByString:@", "]
将给出一个带有字符串的 NSArray，然后您可以在 ;) 上调用 floatValue
