With NSArray
only i can find values as:
NSArray *arr = [NSArray arrayWithObjects:@"299-1-1", @"299-2-1", @"299-3-1", @"399-1-1", @"399-2-1", @"399-3-1", @"499-1-1", @"499-2-1", @"499-3-1", nil];
NSString *search = @"299";
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF CONTAINS %@",[NSString stringWithFormat:@"%@", search]];
NSArray *array = [arr filteredArrayUsingPredicate: predicate];
NSLog(@"result: %@", array);
Found Result
as expected :
result: (
"299-1-1",
"299-2-1",
"299-3-1"
)
But for NSArray
having NSArray
with NSString
NSArray *arr = [NSArray arrayWithObjects:[NSArray arrayWithObjects:@"299-1-1", nil],[NSArray arrayWithObjects:@"399-1-1", nil],[NSArray arrayWithObjects:@"499-1-1", nil], nil];
What will be predicate syntax
here?????
To search in a nested array, you can use the "ANY" operator in the predicate:
NSArray *arr = [NSArray arrayWithObjects:[NSArray arrayWithObjects:@"299-1-1", nil],[NSArray arrayWithObjects:@"399-1-1", nil],[NSArray arrayWithObjects:@"499-1-1", nil], nil];
NSString *search = @"299";
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"ANY SELF CONTAINS %@", search];
NSArray *array = [arr filteredArrayUsingPredicate: predicate];
NSLog(@"result: %@", array);
Output:
(
(
"299-1-1"
)
)
If you want to provide an array of searchTerms then you'll need to change your predicate.
Something like this would do it
NSArray *arr = @[ @"299-1-1", @"299-2-1", @"299-3-1", @"399-1-1", @"399-2-1", @"399-3-1", @"499-1-1", @"499-2-1", @"499-3-1" ];
NSArray *searchTerms = @[ @"299", @"399" ];
NSPredicate *predicate = [NSPredicate predicateWithBlock:^ (id evaluatedObject, NSDictionary *bindings) {
for (NSString *searchTerm in searchTerms) {
if (NSNotFound != [evaluatedObject rangeOfString:searchTerm].location) {
return YES;
}
}
return NO;
}];
NSArray *array = [arr filteredArrayUsingPredicate:predicate];
NSLog(@"result: %@", array);
//#=> result: (
"299-1-1",
"299-2-1",
"299-3-1",
"399-1-1",
"399-2-1",
"399-3-1"
)
NSArray *arr = [NSArray arrayWithObjects:[NSArray arrayWithObjects:@"299-1-1", nil],[NSArray arrayWithObjects:@"399-1-1", nil],[NSArray arrayWithObjects:@"499-1-1", nil], nil];
NSString *search = @"299";
NSMutableArray *filteredArray = [[NSMutableArray alloc] init];
for (NSArray *array in arr) {
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"self CONTAINS %@",search];
if([array filteredArrayUsingPredicate:predicate].count)
{
[filteredArray addObject:[array filteredArrayUsingPredicate:predicate]];
}
}
NSLog(@"%@", filteredArray);
