How to remove empty string data from an NSMutableArray

I am getting an array from php server like:

<__NSArrayM 0x7fe6326f2340>(
 01460367533.jpg,
 01460353708.jpg,
 01460354725.jpg,

no idea, we know nothing about the server or the data, but when it arrives at the device you're still processing that and adding it to the array, what code does that? — Wain

You can create a non-empty array from mutable array.

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"length > 0"];
NSArray *anotherArray = [yourMutableArray filteredArrayUsingPredicate:predicate];

Agree with the first comment, though. You should take care of it while adding data to array.

You can remove multiple occurrence of multiple strings/objects.

NSMutableArray *arr = [NSMutableArray arrayWithObjects:@"hello", @"", @"HI", @" ", nil];

[arr removeObjectsInArray:@[@"", @" "]];

NSLog(@"%@", arr);

I would suggest just use this simple one line of code

[mutableArrayOfStrings removeObject:@""];

to remove empty string items from your mutable string array.
