Those annotations will float in mid-air before dropping because they are moved into the user’s visible map rect. Another is that it also drops the user location … Read more
I’ve had success by creating my own UIBarButtonItem instead of setting the title of the existing one: UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@”Back” style:UIBarButtonItemStylePlain target:nil action:nil]; self.navigationItem.backBarButtonItem = backButton; [backButton release];
NSString *str=@”1,2,3,4″; [str stringByReplacingOccurrencesOfString:@”3,” withString:@””]; That will remove ALL occurrences of @”3,” in str. If you want to remove only the first occurrence of @”3,”: NSString* str = @”1,2,3,4″; NSRange replaceRange = [str rangeOfString:@”3,”]; if (replaceRange.location != NSNotFound){ NSString* result = [str stringByReplacingCharactersInRange:replaceRange withString:@””]; } Hope this helps.

As of iOS5 we have an excellent new way of customizing the appearance of almost any control using the UIAppearance protocol, i.e. [UIBarButtonItem appearance]. The appearance proxy allows you to create application wide changes to the look of controls. Below is an example of a custom back button created with the appearance proxy. Use the … Read more
Here’s how to do it with just one line of code: myview.frame = CGRectMake(23, 50, myview.frame.size.width, myview.frame.size.height); or [myview setFrame:CGRectMake(23, 50, myview.frame.size.width, myview.frame.size.height)];
You can get a list of countries using the NSLocale class’s isoCountryCodes which returns an array of [String]. From there, you get the country name by using NSLocale‘s displayName(forKey:) method. It looks like this: var countries: [String] = [] for code in NSLocale.isoCountryCodes { let id = NSLocale.localeIdentifier(fromComponents: [NSLocale.Key.countryCode.rawValue: code]) let name = NSLocale(localeIdentifier: “en_UK”).displayName(forKey: … Read more
