@inte易做图ce ABCustomAlertView : UIWindow
// 显示
- (void)show;

self.windowLevel = UIWindowLevelAlert;
// 这里，不能设置UIWindow的alpha属性，会影响里面的子view的透明度，这里我们用一张透明的图片
// 设置背影半透明
self.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"alert_bg.png"]];
UIView *view = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 80)] autorelease];
view.backgroundColor = [UIColor blackColor];
view.center = CGPointMake(160, 240);
[self addSubview:view];
}
return self;
}
- (void)show {
[self makeKeyAndVisible];
}
- (void)dismiss {
[self resignKeyWindow];
[self release];
}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
// 点击消失
[self dismiss];
}
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
}
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
}

[self release];

}

@end
这只是基本的思路，调用的时候只要调show和dismiss就可以显示、消失了。。。
补充：移动开发 , IOS ,
