我在應用程序中遇到了另一個問題，我正在浪費這麼多時間。 請問任何人都可以幫助解決這個問題。將圖像添加到UIButton時出現問題。
其實我有一個事件，我應該給予評分該事件爲我寫的代碼爲：
在的cellForRowAtIndexPath ......我有代碼：
(UITableViewCell *)tableView:(UITableView *)tv cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"MasterViewIdentifier"];
//UITableViewCell *cell = nil;
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"MasterViewIdentifier"] autorelease];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
UIView* elementView = [[UIView alloc] initWithFrame:CGRectMake(20,170,320,280)];
elementView.tag = 0;
elementView.backgroundColor=[UIColor clearColor];
[cell.contentView addSubview:elementView];
[elementView release];
}
UIView* elementView = [cell.contentView viewWithTag:0];
elementView.backgroundColor=[UIColor clearColor];
for(UIView* subView in elementView.subviews)
{
[subView removeFromSuperview];
}
if(indexPath.section == 8)
{
UIImage *whiteImg = [UIImage imageNamed:@"white_star.png"] ;
UIImage *yellowImg = [UIImage imageNamed:@"yellow_Star.png"] ;
UIButton *button1 = [[UIButton alloc]initWithFrame:CGRectMake(159, 15, 25, 20)];
[button1 addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
button1.tag = 1;
UIButton *button2 = [[UIButton alloc]initWithFrame:CGRectMake(185, 15, 25, 20)];
[button2 addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
button2.tag = 2;
UIButton *button3 = [[UIButton alloc]initWithFrame:CGRectMake(211, 15, 25, 20)];
[button3 addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
button3.tag = 3;
UIButton *button4 = [[UIButton alloc]initWithFrame:CGRectMake(237, 15, 25, 20)];
[button4 addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
button4.tag = 4;
UIButton *button5 = [[UIButton alloc]initWithFrame:CGRectMake(263, 15, 25, 20)];
[button5 addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
button5.tag = 5;
if(event.eventRatings == 1)
{
[button1 setBackgroundImage:yellowImg forState:UIControlStateNormal];
[button2 setBackgroundImage:whiteImg forState:UIControlStateNormal];
[button3 setBackgroundImage:whiteImg forState:UIControlStateNormal];
[button4 setBackgroundImage:whiteImg forState:UIControlStateNormal];
[button5 setBackgroundImage:whiteImg forState:UIControlStateNormal];
}
else if(event.eventRatings == 2)
{
[button1 setBackgroundImage:yellowImg forState:UIControlStateNormal];
[button2 setBackgroundImage:yellowImg forState:UIControlStateNormal];
[button3 setBackgroundImage:whiteImg forState:UIControlStateNormal];
[button4 setBackgroundImage:whiteImg forState:UIControlStateNormal];
[button5 setBackgroundImage:whiteImg forState:UIControlStateNormal];
}
else if(event.eventRatings == 3)
{
[button1 setBackgroundImage:yellowImg forState:UIControlStateNormal];
[button2 setBackgroundImage:yellowImg forState:UIControlStateNormal];
[button3 setBackgroundImage:yellowImg forState:UIControlStateNormal];
[button4 setBackgroundImage:whiteImg forState:UIControlStateNormal];
[button5 setBackgroundImage:whiteImg forState:UIControlStateNormal];
}
else if(event.eventRatings == 4)
{
[button1 setBackgroundImage:yellowImg forState:UIControlStateNormal];
[button2 setBackgroundImage:yellowImg forState:UIControlStateNormal];
[button3 setBackgroundImage:yellowImg forState:UIControlStateNormal];
[button4 setBackgroundImage:yellowImg forState:UIControlStateNormal];
[button5 setBackgroundImage:whiteImg forState:UIControlStateNormal];
}
else if(event.eventRatings == 5)
{
[button1 setBackgroundImage:yellowImg forState:UIControlStateNormal];
[button2 setBackgroundImage:yellowImg forState:UIControlStateNormal];
[button3 setBackgroundImage:yellowImg forState:UIControlStateNormal];
[button4 setBackgroundImage:yellowImg forState:UIControlStateNormal];
[button5 setBackgroundImage:yellowImg forState:UIControlStateNormal];
}
else
{
[button1 setBackgroundImage:whiteImg forState:UIControlStateNormal];
[button2 setBackgroundImage:whiteImg forState:UIControlStateNormal];
[button3 setBackgroundImage:whiteImg forState:UIControlStateNormal];
[button4 setBackgroundImage:whiteImg forState:UIControlStateNormal];
[button5 setBackgroundImage:whiteImg forState:UIControlStateNormal];
}
[elementView addSubview:button1];
[button1 release];
[elementView addSubview:button2];
[button2 release];
[elementView addSubview:button3];
[button3 release];
[elementView addSubview:button4];
[button4 release];
[elementView addSubview:button5];
[button5 release];
if(isRightButton == YES)
{
button1.enabled = NO;
button2.enabled = NO;
button3.enabled = NO;
button4.enabled = NO;
button5.enabled = NO;
}
else if(isRightButton == NO)
{
button1.enabled = YES;
button2.enabled = YES;
button3.enabled = YES;
button4.enabled = YES;
button5.enabled = YES;
}
[elementView addSubview:ratingsTitleLabel];
cell.accessoryType = UITableViewCellAccessoryNone;
}
return cell;
}
And the action of the button is written as:
-(void)buttonAction:(id)sender
{
rating = [sender tag];
printf("\n Ratig Value inside Button Action~~~~~~~~~~~~~~~~%d",rating);
event.eventRatings = rating;
[tableView reloadData];
}
當我在3.1.2 OS的模擬器中構建應用程序時，它通過顯示星形圖像很好地工作。 當我在3.1.2 O.S設備中創建它時，我的圖標是不顯示的。我在文件名和它的gud中檢查了casesensitivity的代碼，但是Im沒有讓圖像顯示出來。
夥計們幫我解決這個問題。
謝謝， Monish Kumar。
你好傢伙......幫我解決這個問題。 – monish 2010-02-01 09:38:30
圖像加載是否正確？檢查調試，如果你的UIImage實例不是零。嘗試檢查應用程序包中是否缺少圖像。 – Vladimir 2010-02-01 09:48:43
是的圖像加載和UIImage insatnce不是nil.Also圖像出現在應用程序捆綁。 – monish 2010-02-01 10:31:54
