IOS alert dialog box

Alert dialog box
The implementation method is very similar to the operation table. When defining a class, add uialertviewdelegate to process button events later.

IOSCode
@ Interface testcontroller: uiviewcontroller <uialertviewdelegate> {...}

 

The call method is as follows:

 
IOS code
Uialertview * Alert = [[uialertview alloc]

Initwithtitle: @ "title"

Message: @ "message displayed"

Delegate: Self

Cancelbuttontitle: @ "cancel"

Otherbuttontitles: @ "OK", nil];

[Alert show]; // display

[Alert release];

 

The method for event processing is to implement the uialertviewdelegate method.

IOS code
-(void) alertview :( uialertview *) alertview
clickedbuttonatindex :( nsinteger) buttonindex

{< br>
nsstring * newtext = [[nsstring alloc] initwithformat: @ "% d", buttonindex];
leftlabel. TEXT = newtext;
[newtext release];

}
