Draggable items//拖动项目
Here's how to create a simple draggable image.//这是如何生成一个简单的拖动图象
iphone代码
1. Create a new class that inherits from UIImageView
@interface myDraggableImage : UIImageView
{
}
2. In the implementation for this new class, add the 2 methods:
- (void) touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event
{
// Retrieve the touch point 检索接触点 游戏编程 2009FLY文摘,正正博客 WWW.2009FLY.COM
CGPoint pt = [[touches anyObject] locationInView:self];
startLocation = pt;
[[self superview] bringSubviewToFront:self];
}
- (void) touchesMoved:(NSSet*)touches withEvent:(UIEvent*)event
{
// Move relative to the original touch point 相对以前的触摸点进行移动
CGPoint pt = [[touches anyObject] locationInView:self];
CGRect frame = [self frame];
frame.origin.x += pt.x - startLocation.x;
frame.origin.y += pt.y - startLocation.y;
[self setFrame:frame];
}
3. Now instantiate the new class as you would any other new image and add it to your view copyright 2009fly 2009FLY文摘,正正博客 WWW.2009FLY.COM
//实例这个新的类,放到你需要新的图片放到你的视图上
dragger = [[myDraggableImage alloc] initWithFrame:myDragRect];
[dragger setImage:[UIImage imageNamed:@"myImage.png"]];
[dragger setUserInteractionEnabled:YES];
线程:
Java代码
1. Create the new thread:
[NSThread detachNewThreadSelector:@selector(myMethod)toTarget:self withObject:nil];
2. Create the method that is called by the new thread:
- (void)myMethod
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
*** code that should be run in the new thread goes here ***
[pool release];
}
