When using Xcode, you will always need to check the build set in the project with the version(s) you have installed. In other words, the project was created some time ago, with an older SDK. Chances are you are using a much new SDK, so you will need to change that in the build settings to match you SDK version.

Hi John this tutorial is great! I downloaded the source files, and see that (for me at least) the following are missing:
under Products folder: JSONFlickr.app
under Frameworks folder: Foundation.framework , CoreGraphics.framework, and UIKit.framework

It also show “Base SDK Missing” in the Xcode dropdown top left.

I’m new to Xcode and may be overlooking something.

Thx!

Here is a post that discusses initialization, it may provide some insight.

Hi, first off, great tutorial!! I must say I am new to iOS development so please bear with me:)

I do not really understand the function of the -(id)init method. I mean, could you not initialize the arrays in the viewWillLoad method? And whats the need to alloc memory for the view? And after that you call the [self searchFlickrPhotos:@"iPhone"]; function. Why do you do so? The user didn’t want to do so or am I missing something?

Yes, there are probably a number of ways to extend the code and make things more robust if you were to use this within a more complete project. Often times I write short examples with the primary intention to demonstrate a concept and keep things simple…

Hey John,

Thanks for the tutorial !

Just one suggestion : wouldn’t it be nicer to create a Photo class with attributes title, smallImageData and largeImageUrl and then having an NSMutableArray of those instead of storing everything in three separate NSMutableArrays ?

Hi,

Your JSON parser code doesn’t seem to be available anymore, would you mind providing it?

If ‘year’ is an NSString, you can use the method integerValue to convert the string to an integer.

Hello

in the bellow snippet profileType is defined as a NSString while year is defined as an int.
When setting the values of my class with the json object the first line works but the second fail as year expect an int but not a NSString nor a Dictionary Object. What is the good/clean approach to cast my json year entry into an int?

profileType = [NSString stringWithFormat:@"%@", [jsonEntry objectForKey:@"profileType"]]
year = [jsonEntry objectForKey:@"year"]

Thanks :-)
