iOS development UI Chapter---Custom Uiactionsheet

Reprinted from: http://www.cnblogs.com/pengyingh/articles/2343200.html

Uiactionsheet class is an important class that implements warning boxes in iOS development, and in many applications it has been extended to introduce a custom style of uiactionsheet today.

First, Custom Customactionsheet class

The Customactionsheet class inherits the Uiactionsheet, and the specific implementation is as follows:

1) CustomActionSheet.h header file

#import <Foundation/Foundation.h>

@interface Customactionsheet:uiactionsheet {

uitoolbar* ToolBar;

uiview* view;

}

@property (Nonatomic,retain) uiview* view;

@property (Nonatomic,retain) uitoolbar* ToolBar;

/* Because the actionsheet is changed by adding a button to Actionsheet, so the size is related to the number of button Actionsheet

*height = 84, 134, 184, 234, 284, 334, 384, 434, 484

* If you want to use Self.view = Anotherview. Then the size of the another must also be the same size as the view

*/

-(ID) Initwithheight: (float) Height withsheettitle: (nsstring*) title;

@end

2) CUSTOMACTIONSHEET.M implementation file

#import "CustomActionSheet.h"

@implementation Customactionsheet

@synthesize view;

@synthesize ToolBar;

-(ID) Initwithheight: (float) Height withsheettitle: (nsstring*) title

{

self = [super init];

if (self)

{

int theight = height-40;

int btnnum = THEIGHT/50;

for (int i=0; i<btnnum; i++)

{

[Self addbuttonwithtitle:@ "];

}

ToolBar = [[Uitoolbar alloc] Initwithframe:cgrectmake (0, 0, 320, 44)];

Toolbar.barstyle = Uibarstyleblackopaque;

Uibarbuttonitem *titlebutton = [[Uibarbuttonitem alloc] Initwithtitle:title

Style:uibarbuttonitemstyleplain

Target:nil

Action:nil];

Uibarbuttonitem *rightbutton = [[Uibarbuttonitem alloc] initwithtitle:@ "Done"

Style:uibarbuttonitemstyledone

Target:self

Action: @selector (done)];

Uibarbuttonitem *leftbutton = [[Uibarbuttonitem alloc] initwithtitle:@ "Cancel"

Style:uibarbuttonitemstylebordered

Target:self

Action: @selector (Docancel)];

Uibarbuttonitem *fixedbutton = [[Uibarbuttonitem alloc] Initwithbarbuttonsystemitem: Uibarbuttonsystemitemflexiblespace

Target:nil

Action:nil];

Nsarray *array = [[Nsarray alloc] initwithobjects:leftbutton,fixedbutton,titlebutton,fixedbutton,rightbutton,nil];

[ToolBar Setitems:array];

[Titlebutton release];

[LeftButton release];

[Rightbutton release];

[Fixedbutton release];

[Array release];

[Self addsubview:toolbar];

view = [[UIView alloc] Initwithframe:cgrectmake (0, height-44)];

View.backgroundcolor = [Uicolor Grouptableviewbackgroundcolor];

[Self addsubview:view];

}

return self;

}

-(void) Done

{

[Self dismisswithclickedbuttonindex:0 animated:yes];

}

-(void) Docancel

{

[Self dismisswithclickedbuttonindex:0 animated:yes];

}

-(void) dealloc

{

[View release];

[Super Dealloc];

}

@end

Second, using the custom Customactionsheet class display prompt box

#import "TestActionSheetViewController.h"

#import "CustomActionSheet.h"

@implementation Testactionsheetviewcontroller

-(Ibaction) Btndown

{

customactionsheet* sheet = [[Customactionsheet alloc] initwithheight:284.0f

withsheettitle:@ "Custom Actionsheet"];

uilabel* label = [[UILabel alloc] Initwithframe:cgrectmake (0,50, 320, 50)];

Label.text = @ "Here is the control to customize the release";

Label.backgroundcolor = [Uicolor Clearcolor];

Label.textalignment = Uitextalignmentcenter;

[Sheet.view Addsubview:label];

[Sheet ShowInView:self.view];

[Sheet release];

}

@end

The Uilabel here is an example where you can switch to your own content.
