iOS detailed tableview: Built-in refresh, EGO, and search display controller

These days because of the network of the place to live a little problem, in addition to the Q, on the micro-blog other than the Web page can not be landed. Blogs are not followed up.

Resumed today, so continue to update the blog. I also hope that you can continue to comment or give me some advice or exchange:-)

Today found a previous example of a tableview, mainly about up and down pull refresh, so wrote a demo, and then updated to the blog.

Built-in Refresh

Built-in refresh is Apple IOS6 after the introduction of an API, mainly for Tableviewcontroller added a property, Refreshcontrol, so if you want to use this built-in Drop-down refresh, it is best to Your TableView specifies a dedicated view controller.

When used, we need to assign a Uirefreshcontrol object to Refreshcontrol. Follow the header file to see

Three properties, the initialization of three methods, not difficult, and then configure Refreshcontrol

/****** built-in refresh of common generic

settings ******/
uirefreshcontrol *refresh = [[Uirefreshcontrol alloc] init];  
Refresh.attributedtitle = [[Nsattributedstring alloc] initwithstring:@ "Drop-down refresh"];  
Refresh.tintcolor = [Uicolor bluecolor];  
[Refresh Addtarget:self action: @selector (Pulltorefresh) 

forcontrolevents:uicontroleventvaluechanged];  
Self.refreshcontrol = Refresh;

Set up a listening method to simply look at its implementation

Drop-down

Refresh  
-(void) Pulltorefresh  
{  
    //analog network access  
    [UIApplication sharedapplication]. networkactivityindicatorvisible = YES;  
    Self.refreshControl.attributedTitle = [[Nsattributedstring alloc] initwithstring:@ "Refresh

"];  
          
    Double delayinseconds = 1.5;  
    dispatch_time_t poptime = Dispatch_time (Dispatch_time_now, (int64_t) (Delayinseconds * 

nsec_per_sec));  
    Dispatch_after (Poptime, Dispatch_get_main_queue (), ^ (void) {  
        _rowcount = 5;  
        [Self.tableview Reloaddata];  
        Refresh control settings At the end of the refresh  
        [Self.refreshcontrol endrefreshing];  
        Self.refreshControl.attributedTitle = [[Nsattributedstring alloc] initwithstring:@ "Drop-down

Refresh"];  
              
        [UIApplication sharedapplication].networkactivityindicatorvisible = NO;  
        _bottomrefresh.frame = CGRectMake (0, 44+_rowcount*rcellheight, rcellheight);}
