Question

I have a class Events

@interface MeEvents : NSObject {
    NSString* name;**strong text**
    NSString* location;

}

@property(nonatomic,retain)NSString* name;strong text
@property(nonatomic,retain)NSString* location;

In my NSMutablArray I add object of Events

Events* meEvent;
[tempArray addObject:meEvent];

Please tell me how to sort this array by member name.

The easiest way is to use sortUsingComparator: like this:

[tempArray sortUsingComparator:^(id a, id b) {
    return [[a name] compare:[b name]];
}];

If you are sorting these strings because you want to show a sorted list to the user, you should localizedCompare: instead:

[tempArray sortUsingComparator:^(id a, id b) {
    return [[a name] localizedCompare:[b name]];
}];

Or you might want to use localizedCaseInsensitiveCompare:.
