how to split string into NSMutableArray

Question

I want to split string into NSMutableArray

I know

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

is available but this one is for NSArray not for NSMutableArray .

I need because after spliting i want to remove element from array by using

-(void)removeObjectAtIndex:(NSUInteger)index

which is not possible with NSArray.

Thank you

Answer 1

You can also just get a mutable copy of the returned array:

NSMutableArray *array = [[myString componentsSeparatedByString:@"..."] mutableCopy];

Also, remember that copy, like alloc, does allocate new memory. So when used in non-ARC code you must autorelease the copied array or manually release it when you are done with it.

Answer 2

Make a new NSMutableArray using

NSArray *array = [NSString componentsSeparatedByString:@"..."];
NSMutableArray *mutable = [NSMutableArray arrayWithArray:array];

Answer 3

从由componentsSeparatedByString创建的输出NSArray创建一个NSMutableArray。

NSMutableArray *mutableArray = [[NSMutableArray alloc] initWithArray:array];
