![]() But in the case of a duplicate handling process, StoryBoard implementation becomes challenging to update as per the system functionality. ![]() It also produces the end-to-end visualization of the entire system process. They primarily use StoryBoard for quick UI representation based on appropriate design specifications. Explain StoryBoard and Programmatic UIView from an iOS perspective.ĭevelopers can construct a view and add new views to it programmatically for StoryBoard. It also implements the codes and displays the same in a much cleaner representative way.Īmong the different parameters implemented in a method, the completion handler should always remain the last parameter in the list. These can be processed later depending on the system’s capabilities and are not limited to real-time executions. With regard to the methods or functions, these produce distinctive code portions that can be passed. Explain Completion Handler and Blocks from an iOS perspective.īlocks are a language-level feature implemented along with C and C++ languages. So, when there is a rapid change in data or view of the animation process, viewDidAppear is an excellent method to implement the system functionalities. Developers can override this method to implement tasks that do not interfere with the ongoing animation view process. In the case of viewDidAppear, this is mainly called when the animation process, which is involved in the initial view appearance, has been completed. Developers can override this method to process the extra initialization on views implemented from nib files. ![]() In the case of viewDidLoad, this is mainly called when the hierarchy loading process for the view controller has been completed and the records have been loaded into memory successfully. Explain the vieDidLoad and viewDidAppear. So, if the user deletes a message through iPhone, the same will also be deleted from the synced iPad and Mac and vice-versa.
