Question

I have an NSMutableArray of NSMutableDictionary (it’s a plist). Each dictionary in the array has 2 keys: ‘id‘ and ‘lu‘.

How can I find the index in NSMutableArray of NSMutableDictionary where, for example, id = ‘47653’?

I tried to do it but it’s not working:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *basePath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;
NSString *path = [basePath stringByAppendingPathComponent:@"id.plist"];
NSMutableArray *mut_array = [[NSArray arrayWithContentsOfFile:path] mutableCopy];

NSMutableDictionary *mut_dico = [[NSMutableDictionary alloc] init];

NSString *egalIDPlistData = [contentDictio objectForKey:@"id"];

for(mut_dico in mut_array) {
    if([[mut_dico objectForKey:@"id"] isEqualToString:@"47653"]) {
        NSLog(@"Test");
    }
}

The objects in the loaded plist are not mutable.

Try:

for(NSDictionary * dict in mut_array)
{
    if([[dict objectForKey:@"id"] isEqualToString:@"49711"]) {
        NSLog(@"Test");
    }
}
