我想将图像存储在NsMutable Array.But中,但它不能在该函数中工作。但最终在其他功能它正常工作。有人告诉我为什么它不工作。未存储在NSMutableArray中的图像
- (void)readPlistData {
objectButtonArray = [[NSMutableArray alloc] init]; \\Use to store Buttons
editButtonArray = [[NSMutableArray alloc] init]; \\ another array use to store deletebutton(such as.crossmark button.)
selectImage = [[NSMutableArray alloc] init];
self.myPlistPath = [NSString stringWithString:[self plistPath]];
plistArray = [[NSMutableArray alloc] initWithContentsOfFile:self.myPlistPath];
for (int i =0; i< [plistArray count];i++)
{
UIGraphicsEndImageContext();
NSData *imageData = [plistArray objectAtIndex:i];
currentObjectImage = [UIImage imageWithData:imageData] ;
[selectImage addObject:currentObjectImage]; \\value not stored in selectimage NSMutableArray
CGRect imageSize = CGRectMake(0, 0, 100, 90);
UIGraphicsBeginImageContext(imageSize.size); // this will crop
[currentObjectImage drawInRect:imageSize];
UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
imageButton = [[UIButton alloc]initWithFrame:CGRectMake(width, 0, 100, 90)];
[imageButton setTag:tag];
[imageButton addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
[imageButton setImage:newImage forState:UIControlStateNormal];
CGRect backFrame = backView.frame;
backFrame.size.width = 120+width;
backView.frame = backFrame;
[backView addSubview:imageButton];
editButton = [[UIButton alloc]initWithFrame:CGRectMake(width-10, -10, 35, 35)];
[editButton setImage:[UIImage imageNamed:@"DeleteButton.png"] forState:UIControlStateNormal];
[editButton addTarget:self action:@selector(deleteObjectViewImage:) forControlEvents:UIControlEventTouchUpInside];
editButton.hidden = YES;
[editButton setTag:tag];
[backView addSubview:editButton];
tag++;
width = 120 + width;
[objectButtonArray addObject:imageButton];
[editButtonArray addObject:editButton];
}
scrollView.contentSize = backView.bounds.size;
}
有人可以帮助我。
“不工作”是什么意思?这是一个编译器错误?运行时错误? plist没有被加载?图像是错误地创建的?根本没有图像?按钮不显示在视图上?请更具体地说 - 粘贴一些代码并说'不工作'是不好的形式。帮助我们帮助你! – 2011-06-04 08:29:58
