排序后设置NSMutableArray
|
我有一个在UITableView中显示的Marker对象的NSMutableArray。我有一个segmentedControl对数据进行排序。我知道当我NSLog我的信息时，按名称排序是有效的：
// Create sort descriptors
NSSortDescriptor *descriptor = [[[NSSortDescriptor alloc] initWithKey:@\"Name\" ascending:YES selector:@selector(localizedCaseInsensitiveCompare:)] autorelease];
NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:descriptor, nil];
NSArray *sortedArray = [self.MarkersList sortedArrayUsingDescriptors:sortDescriptors];
for (Marker *m in self.MarkersList) {
NSLog(@\"-Name: %@\", m.Name);
}
for (Marker *m in sortedArray) {
NSLog(@\"sorted - Name: %@\", m.Name);
}
if ([segmentControl selectedSegmentIndex] == 0) {
if (self.MarkersList != nil) {
[self.MarkersList removeAllObjects];
[self.MarkersList arrayByAddingObjectsFromArray:sortedArray];
[self.MarkersTableView reloadData];
NSLog(@\"%s\", __FUNCTION__);
for (Marker *m in self.MarkersList) {
NSLog(@\"Name: %@\", m.Name);
}
}
}
没有找到相关结果
