Я добавил UIScrollView из раскадровки и внутри этого прокрутки. У меня есть еще один UIView в виде контейнера. За UIScrollView у меня есть UIImageView тоже как родной брат. Это моя иерархия просмотра.Случай нажатия кнопки не срабатывает иногда для программно созданного UIButton
Теперь я добавляю Просмотров в этом виде контейнера программно.
-(void)setUI
{
int i;
for (i=0; i<[array count]; i++) {
NSLog(@"Object at index %i %@",i,[array objectAtIndex:i]);
UIView *view=[self GetAlertView:i];
[self.contentView addSubview:view];
float sizeOfContent = 0;
if (notY+viewParent.frame.size.height>self.contentView.frame.size.height) {
CGRect frame=self.contentView.frame;
frame.size.height=notY;
self.contentView.frame=frame;
}
self.mainScroll.contentSize = self.contentView.frame.size;
}
Вот как я генерирую виды.

}
Но моя проблема заключается в том, что btnEvac не доступен для просмотра. Но иногда я могу щелкнуть его только один раз. Это мое событие нажатия кнопки.
-(IBAction)EvacuateClick :(UIButton *)sender
{
NSLog(@"Evacuate clicked");
}
Иногда это срабатывает в первый раз. После этого ничего не происходит. Я не знаю, в чем причина. Я установил взаимодействие с пользователем enabled = YES с моим видом прокрутки и контейнером. но не к представлению всплеска изображения. Надеюсь, я тоже этого не хочу. Пожалуйста, помогите мне.
Благодаря
Это, как я загружаю больше вид на нижнюю
- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView {
float bottomEdge = self.mainScroll.contentOffset.y + self.mainScroll.frame.size.height;
if (bottomEdge >= self.mainScroll.contentSize.height) {
// we are at the end
//[self performSelectorInBackground:@selector(callscrol) withObject:nil];
[self callscrol];
}
}
-(void)callscrol
{
if(!loading&& !resNull)
{
float offs = (self.mainScroll.contentOffset.y+self.mainScroll.bounds.size.height);
float val = (self.mainScroll.contentSize.height);
if (offs==val)
{
loading=YES;
start_rec+=1;
[self performSelectorInBackground:@selector(LoadData) withObject:nil];
}
}
}
И получить больше данных с сервера
-(void)LoadData
{
[self.actind startAnimating];
[self.actind setHidden:NO];
loading=YES;
NSString *serverURL = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"BaseURL"];
NSString *queryString=[NSString stringWithFormat:@"GetDisasterAlertsJson?authCode=%@&lastUpdated=%@&version=%@&langId=%@&pageNo=%@&noOfMessages=%@",dm.strAuthCode,lastUpdate,@"1.0",@"1",[NSString stringWithFormat:@"%i",start_rec],@"5"];
NSString *urlString=[NSString stringWithFormat:@"%@%@",serverURL,queryString];
// Create the request.
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:urlString]];
// Create url connection and fire request
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
if (!data) {
NSLog(@"%s: sendAynchronousRequest error: %@", __FUNCTION__, connectionError);
return;
} else if ([response isKindOfClass:[NSHTTPURLResponse class]]) {
NSInteger statusCode = [(NSHTTPURLResponse *)response statusCode];
if (statusCode != 200) {
NSLog(@"%s: sendAsynchronousRequest status code != 200: response = %@", __FUNCTION__, response);
return;
}
}
NSError *parseError = nil;
NSData *dataXMLRemoved=[self ReplaceXMLData:data];
NSLog(@"======= Data XML Removed ======== %@",dataXMLRemoved);
dictionary = [NSJSONSerialization JSONObjectWithData:dataXMLRemoved options:NSJSONReadingAllowFragments error:&parseError];
if (!dictionary) {
NSLog(@"%s: JSONObjectWithData error: %@; data = %@", __FUNCTION__, parseError, [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]);
resNull=NO;
return;
}
// now you can use your `dictionary` object
else
{
NSLog(@"JSON Dictionary================ %@",dictionary);
array=[dictionary objectForKey:@"Cmessage"];
NSLog(@"Array ####### %@",array);
resNull=NO;
loading=NO;
[self.actind stopAnimating];
[self.actind setHidden:YES];
[self setUI];
}
}];
}
похоже, что он не работает после того, как загрузите больше изображений снизу – user1960169
