iOS Project-Contact list

One, Project introduction

First, briefly describe the effect of this project

Enter the program, the first is the login page

Login page Use Nsuserdefault remember login password

Then the

Then the login jump, use the Mbprogresshud

Then the contact list is a uitableview.

Click + to go to the Add Contact page

Click on each line of contact to enter the edit screen.

Click Logout to Eject Uialertcontroller

Two, enter the code

First build the schema of the view in SB

Then set up several corresponding controllers, and do a good job of sub-category link

Then implement the Login interface

First add the observer to monitor the change of the value of the TextField

[[Nsnotificationcenter defaultcenter]addobserver:self selector: @selector (textchange) Name: Uitextfieldtextdidchangenotification object:self.nameTxtFiled];

[[Nsnotificationcenter defaultcenter]addobserver:self selector: @selector (textchange) Name: Uitextfieldtextdidchangenotification Object:self.pwdTextField];

Set up

Nsuserdefaults

Remember password

Setting events

-(void) TextChange

{

self.loginBtn.enabled = self.nametxtfiled.text.length&&self.pwdtextfield.text.length;

}

Set a jump for each Segwe

-(void) Prepareforsegue: (Uistoryboardsegue *) Segue Sender: (ID) Sender {

if ([Segue.identifier isequaltostring:@ "id"]) {

Contacttableviewcontroller *CONTACTVC = Segue.destinationviewcontroller;

Contactvc.title = [NSString stringwithformat:@ "%@ contact list", Self.nameTxtFiled.text];

}

}

Click events

-(ibaction) Loginclick {

if (![ Self.nameTxtFiled.text isequaltostring:@ "DSN"]) {

[Mbprogresshud showerror:@ "User name error"];

Return

}

if (![ Self.pwdTextField.text isequaltostring:@ "123"])

{

[Mbprogresshud showerror:@ "password error"];

Return

}

[Mbprogresshud showmessage:@ "is landing, please wait ..."];
