在我的代码中,我在一个数组中创建了点,并使用该数组创建了 10 个按钮。我将每个按钮的标签按顺序设置为 0 - 9。我想要做的是检查一个按钮何时被滑过(不仅仅是点击),然后能够检查它的标签并根据标签是什么做一些事情!
这是我的代码:
#import "LevelOneController.h"
@interface LevelOneController ()
@end
@implementation LevelOneController
@synthesize whereStuffActuallyHappens, squareLocations;
- (void)viewDidLoad
{
[super viewDidLoad];
NSLog(@"View loaded");
squareLocations = [[NSMutableArray alloc] init];
CGPoint dotOne = CGPointMake(1, 25);
[squareLocations addObject:[NSValue valueWithCGPoint:dotOne]];
CGPoint dotTwo = CGPointMake(23, 25);
[squareLocations addObject:[NSValue valueWithCGPoint:dotTwo]];
CGPoint dotThree = CGPointMake(45, 25);
[squareLocations addObject:[NSValue valueWithCGPoint:dotThree]];
CGPoint dotFour = CGPointMake(67, 25);
[squareLocations addObject:[NSValue valueWithCGPoint:dotFour]];
CGPoint dotFive = CGPointMake(89, 25);
[squareLocations addObject:[NSValue valueWithCGPoint:dotFive]];
CGPoint dotSix = CGPointMake(111, 25);
[squareLocations addObject:[NSValue valueWithCGPoint:dotSix]];
CGPoint dotSeven = CGPointMake(133, 25);
[squareLocations addObject:[NSValue valueWithCGPoint:dotSeven]];
CGPoint dotEight = CGPointMake(155, 25);
[squareLocations addObject:[NSValue valueWithCGPoint:dotEight]];
CGPoint dotNine = CGPointMake(177, 25);
[squareLocations addObject:[NSValue valueWithCGPoint:dotNine]];
CGPoint dotTen = CGPointMake(199, 25);
[squareLocations addObject:[NSValue valueWithCGPoint:dotTen]];
int numby = [squareLocations count];
for (int i = 0; i < numby; i++)
{
NSValue *pointLocation = [squareLocations objectAtIndex:i];
CGPoint tmpPoint = [pointLocation CGPointValue];
UIImage *theSquare = [UIImage imageNamed:@"square.png"];
UIButton *squareButton = [[UIButton alloc] init];
squareButton = [UIButton buttonWithType:UIButtonTypeCustom];
squareButton.frame = CGRectMake(tmpPoint.x, tmpPoint.y, theSquare.size.width, theSquare.size.height);
squareButton.tag = *(&i);
[squareButton setImage:theSquare forState:UIControlStateNormal];
[whereStuffActuallyHappens addSubview:squareButton];
}
}
有谁知道实现这一目标的好方法?谢谢!
