将NSString转换为具有多个条件的NSArray

Question

I have a string that contains some text with periods and commas. I'd like to convert it to an NSArray based on the commas AND the periods. I use this method to separate based on one type of condition, but how do I do that with two?

componentsSeparatedByString:

Thanks.

Answer 1

You can use componentsSeparatedByCharactersInSet: .

For example:

NSString *str = @"1,2.3";

NSArray *arr = [str componentsSeparatedByCharactersInSet:
                [NSCharacterSet characterSetWithCharactersInString:@",."]];

Please refer to NSString Class Reference .

Answer 2

You need to create NSCharacterSet with a comma and a dot in it, and use this method:

- (NSArray *)componentsSeparatedByCharactersInSet:(NSCharacterSet *)separator

Here is an example:

NSArray *arr = [str componentsSeparatedByCharactersInSet:
      [NSCharacterSet characterSetWithCharactersInString:@",."]];

Answer 3

 NSString *tempTextOut = [NSString stringWithFormat:@"jdnfj,adsfsajfhkj,hasdfjhdsjkfh,hdsufhajkdsfhk"];
NSMutableArray *array = [[tempTextOut componentsSeparatedByString: @","] mutableCopy];
NSLog(@"%@",array);

>>OutPut1

jdnfj,
adsfsajfhkj,
hasdfjhdsjkfh,
hdsufhajkdsfhk

and

NSString *tempTextOut = [NSString      stringWithFormat:@"jdnfj,adsfsajfhkj,,,hasdfjhdsjkfh,,,,hdsufhajkdsfhk"];
NSMutableArray *array = [[tempTextOut componentsSeparatedByString: @",,,"] mutableCopy];
NSLog(@"%@",array);

>>OutPut2

 "jdnfj,adsfsajfhkj",
hasdfjhdsjkfh,
",hdsufhajkdsfhk"

Hope,this will help you..
