Use a sort descriptor NSSortDescriptor* sortOrder = [NSSortDescriptor sortDescriptorWithKey: @”self” ascending: NO]; return [myArray sortedArrayUsingDescriptors: [NSArray arrayWithObject: sortOrder]];
You can create a NSMutableArray from the navigationController’s array of viewcontrollers and insert new viewController before the current one. Then set the viewControllers array without animation and pop back. UIViewController *newVC = …; NSMutableArray *vcs = [NSMutableArray arrayWithArray:self.navigationController.viewControllers]; [vcs insertObject:newVC atIndex:[vcs count]-1]; [self.navigationController setViewControllers:vcs animated:NO]; [self.navigationController popViewControllerAnimated:YES];
#include <ifaddrs.h> #include <arpa/inet.h> // Get the INTERNAL ip address – (NSString *)getIPAddress { NSString *address = @”error”; struct ifaddrs *interfaces = NULL; struct ifaddrs *temp_addr = NULL; int success = 0; // retrieve the current interfaces – returns 0 on success success = getifaddrs(&interfaces); if (success == 0) { // Loop through linked list … Read more
