Actually, it’s very simple: [_tableView reloadSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationFade]; From the documentation: Calling this method causes the table view to ask its data source for new cells for the specified sections. The table view animates the insertion of new cells in as it animates the old cells out.
You can do the following: Make an NSTimer that will start up when the app starts or in viewDidLoad and also make a boolean. For example: //Declare the timer, boolean and the needed IBActions in interface. @interface className { NSTimer * timer; bool g; } -(IBAction)theTouchDown(id)sender; -(IBAction)theTouchUpInside(id)sender; -(IBAction)theTouchUpOutside(id)sender; //Give the timer properties. @property (nonatomic, retain) … Read more
Read the Apple iPhone Human Interface Guidelines (HIG). The “splash screen” isn’t supposed to be for branding or displaying a logo, it’s supposed to look like the default condition of the app so it appears to start up quickly. Making it stay there for longer would be a violation of the HIG.
Defaulting to a particular language is not what you should strive for. Suppose a japanese user living in France and fluently speaking French has his phone set to Japanese. Your App would default to German, despite it having a French translation; I guess that’s not what you want and it’s certainly not what the user … Read more
The entry point in a plain Swift module is the file in the module called main.swift. main.swift is the only file which is allowed to have expressions and statements at the top level (all other Swift files in the module can only contain declarations). Cocoa Touch uses the @UIApplicationMain attribute on an implementation of UIApplicationDelegate … Read more
I had to do this enough that I extended UILabel to do it for me: @interface UILabel (BPExtensions) – (void)sizeToFitFixedWidth:(CGFloat)fixedWidth; @end @implementation UILabel (BPExtensions) – (void)sizeToFitFixedWidth:(CGFloat)fixedWidth { self.frame = CGRectMake(self.frame.origin.x, self.frame.origin.y, fixedWidth, 0); self.lineBreakMode = NSLineBreakByWordWrapping; self.numberOfLines = 0; [self sizeToFit]; } @end then to have a label to have a variable multiline height but … Read more
Replying to myself: My understanding of the documentation says that using keyword block and setting the variable to nil after using it inside the block should be ok, but it still shows the warning. __block ASIHTTPRequest *request = [[ASIHTTPRequest alloc] initWithURL:… [request setCompletionBlock:^{ NSDictionary *jsonDictionary = [[CJSONDeserializer deserializer] deserialize:request.responseData error:nil]; request = nil; // …. … Read more
awakeFromNib is called when the controller itself is unarchived from a nib. viewDidLoad is called when the view is created/unarchived. This distinction is especially important when the controller’s view is stored in a separate nib file.
The answer to Using a regular expression to validate an email address explains in great detail that the grammar specified in RFC 5322 is too complicated for primitive regular expressions. I recommend a real parser approach like MKEmailAddress. As quick regular expressions solution see this modification of DHValidation: – (BOOL) validateEmail: (NSString *) candidate { … Read more
As others described, the easiest solution is to put your UIImageView into a UIScrollView. I did this in the Interface Builder .xib file. In viewDidLoad, set the following variables. Set your controller to be a UIScrollViewDelegate. – (void)viewDidLoad { [super viewDidLoad]; self.scrollView.minimumZoomScale = 0.5; self.scrollView.maximumZoomScale = 6.0; self.scrollView.contentSize = self.imageView.frame.size; self.scrollView.delegate = self; } You … Read more
