需要读取@selector,请帮忙看看
解析一个参数到 @selector,实现代码如下:
- (void)viewDidLoad{
[super viewDidLoad];
NewsCell *cell = (NewsCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil){
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"NewsCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
NSString *string = @"image.png";
[self performSelectorInBackground:@selector(doSomeThing::) withObject:nil];
}
-(void) doSomeThing:(UITableViewCell *)newsCell imageName:(NSString *)imageName{
NSLog(@"newsCell: %@", newsCell);
NSLog(@"imageName: %@", imageName);
}
创建了新的UITableViewCell名为cell,是从其它nib文件中加载的,并创建了新字符串名为string
问题,如何将cell和string作为参数发送到 performSelectorInBackground 中的 @selector ?
