Custom cell Upgrade in iOS (Advanced)

The last shared custom cell was optimized: http://blog.csdn.net/qq_31810357/article/details/49611255

To specify the root view:

    Self.window.rootViewController = [[Uinavigationcontroller alloc] initwithrootviewcontroller:[[ Roottableviewcontroller alloc] Initwithstyle:uitableviewstyleplain];

Roottableviewcontroller.m

#import "WGModel.h" #import "WGCell.h" @interface Roottableviewcontroller () @property (nonatomic, Strong) Nsmutabledictionary *datadict; @end @implementation roottableviewcontroller-(void) viewdidload{    [Super Viewdidload];        Self.datadict = [Nsmutabledictionary dictionary];        [Self.tableview Registerclass:[wgcell class] forcellreuseidentifier:@ "cell"];    [Self loaddataandshow];}

Request data:

-(void) loaddataandshow{nsurl *url = [Nsurl urlwithstring:@ "http://api.breadtrip.com/trips/2387133727/schedule/"];    Nsurlrequest *request = [Nsurlrequest Requestwithurl:url]; [Nsurlconnection sendasynchronousrequest:request queue:[nsoperationqueue Mainqueue] completionHandler:^ ( Nsurlresponse *response, NSData *data, Nserror *connectionerror) {if (data! = nil) {Nsarray *ar            Ray = [Nsjsonserialization jsonobjectwithdata:data options:nsjsonreadingallowfragments Error:nil];                For (nsdictionary *dict in array) {NSString *key = dict[@ "Date"];                Nsarray *placesarray = dict[@ "Places"];                Nsmutablearray *mutablearray = [Nsmutablearray array];                    For (Nsdictionary *placesdict in Placesarray) {Wgmodel *model = [[Wgmodel alloc] init];                    [Model Setvaluesforkeyswithdictionary:placesdict];                    Model.isshow = NO; [Mutablearray AddObject: Model];            } [Self.datadict Setobject:mutablearray Forkey:key];        } [Self.tableview Reloaddata]; }                    }];}

self-adapting high

prepare a model class
