How to automatically resize UIImageView to image size in Interface Builder

0

It’s always frustrated me that when I create a UIImageView in Interface Builder I need to manually enter the size of view so that it matches the size of the image. I always go into Finder, open the image in Preview, find out the dimensions and type them into Interface Builder. Painful!

I learned a much better way today. Just drag in a UIImageView object into your .xib. Set the image in the Attributes Inspector. Then select the UIImageView and press Command =. Boom! The UIImageView is automagically resized to the size of the image!

This was the #1 thing that annoyed me about Interface Builder.

Presentation slides and code from my “Polishing Your App” YYC Dev Camp talk now available

I’ve released the presentation notes and posted the code from my YYC Dev Camp #6 talk last week.

Presentation Slides

The presentation slides are available here as a PDF.

Hopefully I’ll soon do a blog post to walk through the steps, but for now, the code is available on GitHub in fully functional examples projects. These are released royalty free for your use (but not the included sample images, those are copyrighted).

Custom UINavigationBar and Stretchable Custom Back Button Code

Here is the project that shows how to create custom UINavigationBar background images on both iOS 4 and iOS 5. It also shows how to create a custom back button that has a text-based title (i.e. not baked into the image) using a stretchable image. I originally learned how to do this from iDev Recipes – How do iPhone apps Instagram/Reeder/DailyBooth implement custom NavigationBars with variable width back buttons? but I have refactored the code significantly to make it more modular and easy to use.

Here is the code:

Full Screen Animations – Path-style open book animation and falling star animation

The other sample code shows how to do a couple of full screen animations. First, it performs a Path-style open book animation when the app opens. This will be included in an upcoming version of the John Gilchrist Calgary Eats and Cheap Eats apps. This works on both iPhone  (portrait only) and iPad (in any orientation). It also shows how to do the falling-star animation used in those same apps.

iOS: How to embed a Twitter feed and/or hashtag in your app

0

One of my recent projects required a simple Twitter feed integration. Basically just a table view that showed recent tweets from either a @username or a #hashtag. No requirements to post tweets or anything like that. This seems to be a fairly common request for a lot of clients.

Being lazy, I didn’t want to sign up for an API Key or anything onerous. Someone recommended a very simple way to do this, which worked beautifully. I wanted to pass it on.

What you’ll need:

  1. JSONKit – to quickly parse the JSON.
  2. ASI – A nice simplified library for doing asynchronous HTTP requests.
  3. Google Toolbox for Mac – A useful toolkit from Google. Used for escaping HTML-style escapes.
  4. (Optional) JSONView – An extension for Chrome to very nicely format JSON.

Step 1. Find the Twitter URL
Twitter provides a really simple API that returns recent tweets in JSON format. If you do a normal search like this:

you can get back the results in JSON format by simply tweaking the URL:

If you’re using Chrome, try using JSONView to nicely visualize that. Perfect! Recent tweets about a certain theme, all in a nice machine-parseable format, no API key required. What’s more, you can use their Advanced Search GUI to tweak the query then still get back the results in JSON. Using that, I found I could combine a hashtag (#epicwinning) and a username (@charliesheen) like so:

Step 2. Set up your project
Add JSONKit and ASI to your project. This is pretty straightforward, I’m not going to walk through it. Soon we’ll see that I also needed GTM (Google Toolbox for Mac). Being a little lazy and not wanting the whole thing, I just added these two files to my project.
  • GTMNSString+HTML.h
  • GTMNSString+HTML.m

 Then I tweaked the .m file as follows to avoid external dependencies:
//#import "GTMDefines.h"
#define _GTMDevLog NSLog
#define _GTMDevAssert NSAssert
Step 3. Make the Request
Here we make a simple ASI request to fetch the recent tweets.
- (void)loadTweets
{
    // Looking for #kTwitterHashtag or @kTwitterUsername
    NSString *urlString = [[[@"http://search.twitter.com/search.json?q=%23" stringByAppendingString:(NSString *)kTwitterHashtag]
                            stringByAppendingString:@"+OR+%40"] stringByAppendingString:(NSString *)kTwitterUsername];

    ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:urlString]];
    request.delegate = self;
    [request startAsynchronous];
}
Note that Cocoa started going a little crazy when I had one big format string with things like %40 in there. I ended up breaking the string into smaller parts and appending them.

Step 3. Parse the result
When the HTTP request finishes, ASI will call your delegate method. I simply use my UITableView’s mutable array of model objects and replace its content with the “results” array contents from the JSON.
- (void)requestFinished:(ASIHTTPRequest *)aRequest
{
    NSDictionary *result = [aRequest.responseString objectFromJSONString];

    // an array of NSDictionarys with the properties
    // properties can be seen by looking at the URL with Chrome extension JSONView
    [_modelObjects removeAllObjects];
    [_modelObjects addObjectsFromArray:[result objectForKey:@"results"]];

    [self.tableView reloadData];
}
In your, -tableView:cellForRowAtIndexPath: method, just grab the key from the JSON that you wanted.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    .... // Get the cell

    NSDictionary *tweet = [_modelObjects objectAtIndex:indexPath.row];
    cell.textLabel.text = [tweet objectForKey:@"from_user"];
    cell.detailTextLabel = [[tweet objectForKey:@"text"] gtm_stringByUnescapingFromHTML];
}
Why do I use the Google Toolbox gtm_stringByUnescapingFromHTML? Because the returned JSON has things like this in it:
“I think I dislike the whole &quot;[email protected]&quot; phenomena”.
Those &quot; need to be unescaped into normal quotes. This is also true for lots of other characters – ampersands, less than, greater than, etc.

Don’t forget to handle errors. In my case, I just made a fake tweet entry which said the request failed.
- (void)requestFailed:(ASIHTTPRequest *)request
{
    NSLog(@"Fetching tweets failed. Error: %@", [[request error] localizedDescription]);
    [_modelObjects removeAllObjects];

    NSDictionary *fakeErrorTweet = [NSDictionary dictionaryWithObjectsAndKeys:
                                    @"Twitter Error", @"from_user",
                                    @"Could not fetch tweets. Maybe Twitter is down?", @"text",
                                    nil];
    [_modelObjects addObject:fakeErrorTweet];
    [self.tableView reloadData];
}
Summary
That’s all there is to it. Pretty simple right?
