How to convert string to array in objective C. i.e,I have a string,
NSString *str = @"Hi,How r u";
This should be converted into an array *NSMutableArray arr , where in
arr[0] = "Hi"
arr[1] = ","
arr[2] = "How"
arr[3] = "r"
arr[4] = "u"
Can anybody help with the idea to crack this thing.
NSString *str=@"Hi,How r u";
NSArray *arr = [str componentsSeparatedByString:@","];
NSString *strSecond = [arr objectAtIndex:1];
NSMutableArray *arrSecond = [strSecond componentsSeparatedByString:@" "];
NSString *strHow = [arr objectAtIndex:0];
NSString *strAre = [arr objectAtIndex:1];
NSString *strYou = [arr objectAtIndex:2];
[arr removeObjectAtIndex:1];
[arr addObject:@","];
[arr addObject:strHow];
[arr addObject:strAre];
[arr addObject:strYou];
arr is the desired array.
I guess this link will help you.
NSString *str = @"Hi,How r u";
NSArray *listItems = [str componentsSeparatedByString:@","];
You have to do,
NSString *str = @"Hi,How r u";
NSArray *arr = [str componentsSeparatedByString:@" "];
And, in order for this to work as you expect, there should be a white-space between "Hi," and "How". Your string should look like @"Hi, How r u".
try this
NSString *str2=@"Hi,How r u";
NSMutableArray *arary = [[NSMutableArray alloc] initWithArray:[str2 componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@", "]]];
NSLog(@"%@",arary);
if you want , as a object
NSString *str2=@"Hi,How r u";
str2 = [str2 stringByReplacingOccurrencesOfString:@"," withString:@" , "];
NSMutableArray *arary = [[NSMutableArray alloc] initWithArray:[str2 componentsSeparatedByString:@" "]];
NSLog(@"%@",arary);
You can use the NSString method componentsSeparatedByString. Take a look at the reference here.
