我有一个自动滚动的 UIScrollView，我使用 initWithFrame 创建了几个按钮，每个按钮都有一个图像和一个独特的操作（方法），并将它们全部添加到滚动视图中。按钮的图像可以随着滚动视图自动滚动，但是当我单击每个按钮时，这不是我分配给该按钮的方法。当我点击同一个位置时，无论经过哪个按钮，它都会转到相同的方法，而不是该按钮的方法。下面是我创建按钮的代码：
for (int i = 0; i < 4; i++) {
//create an imageView object in every 'page' of the scrollView.
CGRect frame;
frame.origin.x = 62 * i;
frame.origin.y = 0;
frame.size = CGSizeMake(52.0, 52.0);
myButton = [[UIButton alloc] initWithFrame:frame];
[myButton setImage:[MyImageArray objectAtIndex:i] forState:normal];
switch (i) {
case 0:
[myButton addTarget:self action:@selector(aMethod0) forControlEvents:UIControlEventTouchUpInside];
break;
case 1:
[myButton addTarget:self action:@selector(aMethod1) forControlEvents:UIControlEventTouchUpInside];
break;
case 2:
[myButton addTarget:self action:@selector(aMethod2) forControlEvents:UIControlEventTouchUpInside];
break;
case 3:
[myButton addTarget:self action:@selector(aMethod3) forControlEvents:UIControlEventTouchUpInside];
break;
default:
break;
}
[self.MyScrollView addSubview:myButton];
下面是自动滚动scrollview的代码：
- (void)move_pagination {
UIPageControl *pgCtr = MyPageControl;
CGFloat contentOffset = MyScrollView.contentOffset.x;
__block int nextPage = (int)(contentOffset/(MyScrollView.frame.size.width+10)) + 1 ;
[UIView animateWithDuration:10
delay:0
options:UIViewAnimationOptionCurveLinear | UIViewAnimationOptionAllowUserInteraction
animations:^{
if( nextPage!=3 ) {
MyScrollView.contentOffset = CGPointMake(nextPage*(10+MyScrollView.frame.size.width), 0);
pgCtr.currentPage=nextPage;
// else start sliding from 1 :)
} else {
nextPage = 1;
MyScrollView.contentOffset = CGPointMake(0, 0);
MyScrollView.contentOffset = CGPointMake(nextPage*(10+MyScrollView.frame.size.width), 0);
pgCtr.currentPage=2;
}
}
completion:nil];
}
有任何线索为什么会发生这种奇怪的行为吗？谢谢。
试试这个代码..
在你看来确实加载方法
float x=62;
for(int i=0;i<4;i++)
{
self.stack=[UIButton buttonWithType:UIButtonTypeCustom];
self.stack.frame=CGRectMake(x+(62*i), 100, 52, 52);
[self.stack setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[self.stack setTitle:[self.titleName objectAtIndex:i] forState:UIControlStateNormal];
[self.stack setBackgroundColor:[UIColor redColor]];
self.stack.tag=i;
[self.stack addTarget:self action:@selector(actionMethod:) forControlEvents:UIControlEventTouchUpInside];
//your scroll view
//[self.scrView addSubview:self.btnlabe1];
[self.view addSubview:self.stack];
}
并创建这样的方法......
-(void)actionMethod:(id)sender
{
UIButton *button=(UIButton *)sender;
switch (button.tag) {
case 0:
NSLog(@"ACTIONMETHOD CODE HERE");
break;
case 1:
NSLog(@"ACTIONMETHOD1 CODE HERE");
break;
case 2:
NSLog(@"ACTIONMETHOD2 CODE HERE");
break;
case 3:
NSLog(@"ACTIONMETHOD3 CODE HERE");
break;
default:
break;
}
}
编辑过的代码
float x=62;
for(int i=0;i<4;i++)
{
self.stack=[UIButton buttonWithType:UIButtonTypeCustom];
self.stack.frame=CGRectMake(x+(62*i), 100, 52, 52);
[self.stack setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[self.stack setTitle:[temp objectAtIndex:i] forState:UIControlStateNormal];
[self.stack setBackgroundColor:[UIColor redColor]];
switch (i) {
case 0:
[self.stack addTarget:self action:@selector(aMethod0) forControlEvents:UIControlEventTouchUpInside];
break;
case 1:
[self.stack addTarget:self action:@selector(aMethod1) forControlEvents:UIControlEventTouchUpInside];
break;
case 2:
[self.stack addTarget:self action:@selector(aMethod2) forControlEvents:UIControlEventTouchUpInside];
break;
case 3:
[self.stack addTarget:self action:@selector(aMethod3) forControlEvents:UIControlEventTouchUpInside];
break;
default:
break;
} //your scroll view
//[self.scrView addSubview:self.stack];
[self.view addSubview:self.stack];
}
和方法
-(void)aMethod0
{
NSLog(@"action 0");
}
-(void)aMethod1
{
NSLog(@"action 1");
}
-(void)aMethod2
{
NSLog(@"action 2");
}
-(void)aMethod3
{
NSLog(@"action 3");
}
