The shadow of the control appears in iOS code control

Only need to put the corresponding space, to rewrite. I developed the main target for UIButton this control

. h files, as follows:

#import

#import

@interface Shadowbutton:uibutton

{

Uicolor *shadowcolor;

}

@property (nonatomic, strong) Uicolor *shadowcolor;

@end

. m files, as follows

#import "ShadowButton.h"

@implementation Shadowbutton

@synthesize Shadowcolor;

-(void) SetProperty

{

Self.imageedgeinsets = Uiedgeinsetsmake (0,-1, 3, 2);

Self.shadowcolor = [Uicolor Graycolor];

}

-(ID) initWithFrame: (CGRect) frame

{

self = [super Initwithframe:frame];

if (self) {

Initialization code

}

return self;

}

-(ID) Initwithcoder: (Nscoder *) Adecoder

{

self = [super Initwithcoder:adecoder];

if (self) {

[Self setProperty];

}

return self;

}

Only override drawrect:if you perform custom drawing.

An empty implementation adversely affects performance during.

-(void) DrawRect: (cgrect) rect

{

Drawing Code

Cgcontextref context = Uigraphicsgetcurrentcontext ();

CGRect frame = rect;

Uiedgeinsets insets = self.imageedgeinsets;

Frame.origin.x +=insets.left;

FRAME.ORIGIN.Y +=insets.top;

Frame.size.width-= (insets.left + insets.right);

Frame.size.height-= (insets.top + insets.bottom);

if (Shadowcolor) {

Cgcontextsetshadowwithcolor (Context, Cgsizemake (Insets.right, Insets.bottom), [Shadowcolor Cgcolor]);

}

UIImage *image = self.imageView.image;

[Image Drawinrect:frame];

}

@end
