In iOS, implementing an app to launch another application, using UIApplication's OpenURL: Method can be implemented, here is the example of test jumping to test02. (These two projects need to be created first)

Registering a Custom URL protocol (in test)

The app that was launched first needs to register a custom URL protocol with the iphone. This is done in the Info.plist file.

1. Right-click and select "Add Row"

2. Key value Select "URL Types"

3. Open the Item 0″ and add a URL identifier for the key. Can be any value, but it is recommended to use "anti-domain name" (for example, "Com.fcplayer.test").

4. Add a line under "Item 0".

5. Select "URL schemes" as key.

6. Enter your URL protocol name (e.g. "test://" should be written "test"). If necessary, you can add multiple protocols here.

The operation is as follows:

7. Two item URL identifier cannot be the same, and the URL schemes of item 0 cannot be the same, this needs to be noted .

Accessing the custom URL (in test02)

Launch another application in the main application by accessing the custom URL: (test is installed, this code is written in another application, such as test02)

-(void) viewdidload {

[Super viewdidload];

UIButton *btn = [UIButton buttonwithtype:uibuttontypecustom];

Btn. Frame = CGRectMake (+, +, + );

Btn. backgroundcolor = [uicolor redcolor];

[Btn addTarget:self action:@selector(onbtnclick) forcontrolevents: UIControlEventTouchUpInside];

[self. View addsubview: btn];

}

-(void) onbtnclick{

nsurl * urlstr = [nsurl urlwithstring:@ "test://x=100"]; The following is a parameter

if ([[uiapplication sharedapplication] canopenurl: Urlstr]) {

NSLog(@ "can go to test");

[[uiapplication sharedapplication] openURL: urlstr];

}Else{

NSLog(@ "Can not go to test!!!!! ");

}

}

Custom processing URL (in test)

Sometimes we need to send parameters to another application in addition to booting, which can also be done through custom URLs, such as:

test://config=1&abar=2

In general, we parse the URL from the parameter to display it in the view or store it in the userpreference. The following example stores the URL as a URL variable in user preference or prints it out:

In this case, we have to do the custom processing in the launch application, and implement the message in delegate (Cocos2d added in appdelegate), for example:

-(BOOL) Application: (uiapplication *) application OpenURL: (nsurl *) URL sourceapplication: ( nsstring *) sourceapplication annotation: (ID) annotation{

if(!url) {

return NO;

}

nsstring *urlstring = [url absolutestring];

NSLog(@ "%@", urlstring);

return YES;

}

Methods such as calling map phones

How to use OpenURL:
View Plaincopy Toclipboardprint?
[[UIApplication sharedapplication] Openurl:[nsurl urlwithstring:appstring]];
Among the system's appstring are:

1.Map Http://maps.google.com/maps?q=Shanghai
2.Email Mailto://[email protected]
3.Tel tel://10086
4.MSG sms://10086
OpenURL can help you run Maps,sms,browser,phone and even other applications. This is a piece of code that I often need to use in iphone development, and it's just a single line.
-(ibaction) Openmaps {
Open map
Nsstring*addresstext = @ "Beijing";
@ "1Infinite Loop, Cupertino, CA 95014";
Addresstext =[addresstextstringbyaddingpercentescapesusingencoding:nsasciistringencoding];
Nsstring*urltext = [nsstringstringwithformat:@ "http://maps.google.com/maps?q=%@", Addresstext];
NSLog (@ "urltext===============%@", urltext);
[[Uiapplicationsharedapplication] Openurl:[nsurl Urlwithstring:urltext];
}

-(ibaction) Openemail {
Open mail/Fire off a email to Apple support
[[UIApplication sharedapplication]openurl:[nsurl urlwithstring:@ "Mailto://[email protected]"];
}

-(ibaction) Openphone {

Dial number
Callgoogle 411
[[UIApplication sharedapplication] openurl:[nsurl urlwithstring:@ "tel://8004664411"];
}

-(ibaction) opensms {
Open sms
Text Togoogle SMS
[[UIApplication sharedapplication] openurl:[nsurl urlwithstring:@ "sms://466453"];
}

-(ibaction) Openbrowser {
Open your browser
Lanuch any IPhone developers fav site
[[UIApplication sharedapplication] openurl:[nsurl urlwithstring:@ "http://itunesconnect.apple.com"];
}
Call Google Maps inside iphone program

Use the Cllocationmanager class, Mkmapview. and achieve <MKMapViewDelegate,CLLocationManagerDelegate>
Initialize Cllocationmanager,cllocationmanager to get current geographic coordinates
Locmanager=[[cllocationmanager Alloc]init];

[Locmanager setdelegate:self];
Set accuracy
[Locmanager Setdesiredaccuracy:kcllocationaccuracybest];

[Locmanager startupdatinglocation];
After execution, the proxy method is automatically invoked:
