Apostila iPhone - Manipulando um Picker View

Podemos manipular a seleção feita pelo usuário, para isso vamos modificar o método showHello.

NSInteger row = [dataPicker selectedRowInComponent:0];

NSString *selected = [dataElementos objectAtIndex:row];

lblHello.text = selected;

Exercício

  1. Crie um projeto chamado iPicker. Crie um Picker View com todos os estados do Brasil, crie um botão que quando pressionado exiba o conteúdo selecionado no Picker View.
