I am working on a UITextView related problem recently, the widget, which have a fixed size, but need to show all content passed in. The text passed in have different length, so the font size should be different. The code snippet below will change the font size dynamically based on the text. // Set the text before setting font size my_text_view.text = foo_text; // Set the default font name and size int pre_defined_font_size = 14; my_text_view.

With the new permission schema in iOS6, app should acquire authentication before accessing calendar. So the code for calendar operation should be surrounded like this: EKEventStore *eventStore = [[EKEventStore alloc] init]; EKEvent *event = [EKEvent eventWithEventStore:eventStore]; [eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) { if (granted) { // Calendar operation } }]; As you can see, the code for calendar operation is written in a block. After the operation completed, you may want to show customer an alert box to say the operation is done.
