Swift Base demo contains refresh, load, network request, MVC

Swift has a alamofire third party is making a request for the network, it is written by the author of the Swift form of afnetworking, today first introduced, using Pod to import Afnetworking,svprogresshud, Mjrefresh and other third-party implementation to refresh data, load more, network requests, while using the MVC model for interface Building, then study the function of Alamofire network request, and then share to everyone ....

This article has two interfaces, the first interface directly uses the afnetworking to make the network request, then the interface displays

The first interface creates the table:

Self.mytableview = Uitableview.init (Frame:CGRect.init (x:0, y:0, Width:screen_w, Height:screen_h), style:uitableviews Tyle.plain);
Self.myTableView.delegate = self;
Self.myTableView.dataSource = self;
Self.myTableView.rowHeight = 80;
Self.myTableView.tableHeaderView = Uiview.init ();
Self.myTableView.tableFooterView = Uiview.init ();
Self.view.addSubview (Self.mytableview);
Register cell
Self.myTableView.register (mycelltableviewcell.self, Forcellreuseidentifier: "MyCell");
NIB Registration
Self.tableView.registerNib (uinib (nibname: "Mycelltableviewcell", Bundle:nil), Forcellreuseidentifier: "MyCell")
Add drop-down refresh
Self.myTableView.mj_header = Mjrefreshnormalheader (refreshingblock: {
Data loading
Self.pageindexi = 1;
Self.datahttprequest (PageIndexStr:NSString.init (format: "%d", Self.pageindexi));
});
Set Startup to refresh
Self.myTableView.mj_header.beginRefreshing ();

Then make the network request method:

MARK:-------afnetworking basic Data Request form (not encapsulated method)
Func datahttprequest (pageindexstr:nsstring) {

Svprogresshud.show (withstatus: "Loading");
If Pageindexstr.isequal (to: "1") {
Self.dataArray.removeAllObjects ();
}

Let urlstr = "http://www.healthmanage.cn/android/hrsBabyAction_loadHrsBabyHealth.action";
Let paramsdic = ["UserId": "38567", "pagesize": "8", "PageIndex":p ageindexstr];

Afnetworking using POST requests
Let SessionManager = Afhttpsessionmanager.init ();
SessionManager.responseSerializer.acceptableContentTypes?. Insert ("Text/plain");
Sessionmanager.post (Urlstr, Parameters:paramsdic, Progress:nil, Success: {(_, Responseobject), Void in
Print ("Output data request results at this time ... \ (responseobject)");

Svprogresshud.dismiss (withdelay:1);
Self.myTableView.mj_header.endRefreshing ();
Guard statement, used to determine when a condition is not met and exits safely, not crash
Guard (Responseobject as?) nsdictionary)! = Nil else{
Print ("The return data is nil, or the type does not match");
Return
};
Let Resultdic = Responseobject as! Nsdictionary;
Let SUCCESSB = resultdic["Success"] as! Bool;
if (SUCCESSB) {
If a value is returned
Let ItemArray = resultdic["ITEMS"] as! Nsarray;

if (self.myTableView.mj_footer! = nil)
{
Self.myTableView.mj_footer.endRefreshing ();
}
Else
{
Determine the number of arrays and page, add pull-up load if eligible
if (Itemarray.count = = 8 && pageindexstr.isequal (to: "1"))
{
Self.myTableView.mj_footer = Mjrefreshbacknormalfooter (refreshingblock:{(), Void in

Self.pageindexi = self.pageindexi+1;
Self.datahttprequest (PageIndexStr:NSString.init (format: "%d", Self.pageindexi));
})
}
}

For DiC in ItemArray {
Because the array is: [String:anyobject] Dictionary type, you cannot use as. Nsdictionary, I understand that, I don't know, right?
Let Itemdic = dic as! [String:anyobject];
Self.dataArray.add (Itemdic);
}
Self.myTableView.reloadData ();
}
Else
{
Request no data novalue situation
If self.dataarray.count>0{
Self.myTableView.mj_footer.endRefreshing ();
Self.myTableView.mj_footer = nil;
}
}
}) {(_, error) in
Print ("Request data error Report ... \ (error)");
Svprogresshud.showerror (withstatus: "Network request Error");
}

After the first interface is finished, the second layer of the interface is designed using the MVC structure for style creation:

Create a tabular interface, then use the Data Request tool and model to parse the data, then display the model data in the cell

Data Request Tool Method:

Tool methods for creating request data
Parameter description: mtype: Mode urlstring:url parametersdic: Parameter success: Successful closure structure failure: failure closure structure
Func Urlrequesttool (mtype:methodtypes,urlstring:string,parametersdic:dictionary<string,any>?, Successcomplete: @escaping successclosure,failurecomplete: @escaping failureclosure) {
Svprogresshud.show (withstatus: "Loading");
if mtype = =. GET {
Self.get (URLString, Parameters:parametersdic, Progress:nil, Success: {(_, Respdata), Void in
Return data
Svprogresshud.dismiss (withdelay:1);
Successcomplete (Respdata);
}, Failure: {(_, Err) in
return error
Svprogresshud.dismiss (withdelay:1);
Failurecomplete (ERR);
})
}else{
Self.post (URLString, Parameters:parametersdic, Progress:nil, Success: {(_, Respdata) in
Return data
Svprogresshud.dismiss (withdelay:1);
Successcomplete (Respdata);
}, Failure: {(_, Err) in
return error
Svprogresshud.dismiss (withdelay:1);
Failurecomplete (ERR);
})
}
}

Model class:

Class Mydic:nsobject {
var petnamestr:string!;
var genderidstr:string!;
var birthdaystr:string!;

Init (Dict:[string:anyobject]) {
Super.init ();
Self.petnamestr = dict["PetName"] as! string!;
Self.genderidstr = dict["Genderid"] as! string!;
Self.birthdaystr = dict["Birthday"] as! string!;
}
}

Data Display in cell:
Func Setmydicmodel (Datamodel:mydic)
{
Self.nameLabel.text = Datamodel.petnamestr;
Let Sexstr = datamodel.genderidstr;//can also be turned into nsstring use
NSString has a method isequaltostring method used to determine whether two strings are exactly equal, string does not have this method, but because string is a value type, you can use = = to determine whether it is exactly equal.
if sexstr = = "1" {
Self.sexImgView.image = Uiimage.init (named: "Baby_sex_boy");
Self.headImgView.image = Uiimage.init (named: "Baby_default_boy");
}
Else
{
Self.sexImgView.image = Uiimage.init (named: "Baby_sex_girl");
Self.headImgView.image = Uiimage.init (named: "Baby_default_girl");
}

Self.birthDayLabel.text = nsstring.init (format: "Birthday:%@", datamodel.birthdaystr) as String;
}
