Split up NSString using a comma

问题

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".

I'm trying to split this up into two separate values by splitting at the comma.

Any advice? Thanks!!

回答1:

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

回答2:

NSString* myString = @"32.0235, 1.345".
NSArray* myArray = [myString  componentsSeparatedByString:@","];

NSString* firstString = [myArray objectAtIndex:0];
NSString* secondString = [myArray objectAtIndex:1];

See in documentation

回答3:

You want:

- (NSArray *)componentsSeparatedByString:(NSString *)separator

using @"," as separator.

回答4:

This is work for me as I was not looking to define any Array.

NSString* firstString = [[myString componentsSeparatedByString:@","] objectAtIndex:0];

回答5:

Try [yourCommaSeparatedString componentsSeparatedByString:@", "]
that will give a NSArray with strings you can then call floatValue on ;)
