iOS mbprogresshud effects Learning

In the open source China iOS client also used the Mbprogresshud this special effect, the main role for the application to show a transition role, commonly used to open a networked page loading process, to prevent the phenomenon of suspended animation, if the speed of slow to tell the user has been very hard to load.

On GitHub: Https://github.com/jdg/MBProgressHUD

The source code also comes with a demo, display 13 animation effect, you can choose the special effects to use as needed, the use of the same method is basically the same, when using only add MBProgressHUD.h and mbprogresshud.m into the project, in the use of the file added # Import "MBProgressHUD.h"

Only one effect is used in the open source Chinese iOS client when we select a piece of information to view the details:

We are jumping to the implementation of the Code section, in the NEWSDETAIL.M Clickfavorite and Viewdidload methods

Analyze the Viewdidload method,

The first is to determine if the network is connected, if it is

Defines a Mbprogresshud object to be initialized in the current view.

[toolShowhud:@ " loading " Andview:self.viewAndhud:HUD]; is a package in the Tool class, Setting display information for Mbprogresshud

[CPP]View Plaincopy

1. +  (void) Showhud: (nsstring *) text  andview: (uiview *) View andhud: (mbprogresshud *) hud  
2. {   
3.     [VIEW ADDSUBVIEW:HUD];  
4.      hud.labelText = text; //display prompt   
5.     hud.dimbackground = yes; //make the background black and gray, Mbprogresshud Cheng Gaoliang display   
6.     hud.square = YES; //set the height and width of the display box as   
7.     [HUD SHOW:YES];  
8. }  

Then use the getPath:parameters:success:failure: Method of the Afnetwork class library to determine whether the requested URL was successful in the block block and execute the [Tool getoscnotice2:o Peration.responsestring]; This method is also encapsulated in the tool class, encapsulated by the Tbxml parser, if the parse succeeds immediately set Mbprogresshud hidden properties [HUD Hide:yes]; If the requested URL is not successfully set directly Mbprogresshud hidden property [HUD Hide:yes], then use Gcdiscreetnotificationview to notify "error network no connection";
