问题 I'm currently making an iOS App for my school, and have no previous experience with iOS programming. However, I do have experience with HTML/PHP/MySQL. Currently we have a basic tab bar application with 5 tabs at the bottom. Obviously, since this is an app for a school, it needs to be dynamic and hopefully we can set something up to connect to a database and retrieve school lunch menus, and news. I know how to connect to a database normally with PHP, but I have no idea how to do it using the

问题 In the 3.1 SDk, Apple added support for associated objects. However, the simulator will not compile code that includes references to objc_setAssociatedObject, objc_getAssociatedObject, et al. (Undeclared errors) Is there away around this? Can I make the iPhone simulator compile this code? I would hate to have to do all testing on the device. Update Bug Filed: rdar://7477326 回答1: A quick and dirty workaround (largely untested, may be buggy): #if TARGET_IPHONE_SIMULATOR #import <objc/runtime.h>

问题 I'm working on a multiview app for iPhone and currently have my views (VIEW) set up and their transitions (CONTROLLER?) working nicely. Now I'd like to add objects for the actual program data (MODEL). My question is: How should I structure my data to adhere to the Model View Controller (MVC) design pattern? I know I should create separate classes to implement my data structures and that my controller classes can pass messages to them from the view, but are there any other organizational

问题 I've been searching for a way to make the UISlider progress bar taller, that is, increase the height. However, I haven't had any success. I don't want to use a custom image or anything, just make it taller, so the UISlider doesn't look so thin. Am I missing something super obvious? 回答1: The accepted answer will undesirably change the slider's width in some cases, like if you're using a minimumValueImage and maximumValueImage . If you only want to change the height and leave everything else

问题 I'm using this code to delete a UITableViewCell, but when I swipe to delete, it is showing the minus sign on the right first, then deleting. I took a video to help illustrate my point: Video on YouTube - (void)setEditing:(BOOL)editing animated:(BOOL)animate { [self.tableView setEditing: !self.tableView.editing animated:YES]; if (self.tableView.editing) [self.navigationItem.leftBarButtonItem setTitle:@"Done"]; else [self.navigationItem.leftBarButtonItem setTitle:@"Edit"]; } -(void)tableView:
