2.i turn on the userInteractionEnabled of UIButtons UIView1 UIView2 , u can see in the code :
#import "TableViewDataSource.h"
#implementation TableViewDataSource
#synthesize tableView;
#synthesize tableCell;
#synthesize LHfetchedResultsController;
#synthesize numberOfRows;
#synthesize dataTemp;
#synthesize paused;
#synthesize type;
#synthesize imgAche;
#synthesize cellHeight;
#synthesize subHeaderViewFrame;
-(id)initWithTableView:(UITableView *) tableView
{
self = [super init];
if (self) {
self.tableView = tableView;
self.tableView.dataSource = self;
self.tableView.delegate = self;
self.tableView.tableHeaderView = [self setHeaderView];
}
return self;
}
-(UIView *)setHeaderView
{
CGSize screenSize = [UIScreen mainScreen].bounds.size;
UIView * container = [[UIView alloc] init];
container.frame = CGRectMake(0, 0, screenSize.width, 20);
container.userInteractionEnabled = YES;
UIView * headerView = [[UIView alloc] init];
headerView.frame = CGRectMake(0, 0, screenSize.width*1.5, 20);
headerView.tag = 01;
headerView.userInteractionEnabled = YES;
[container addSubview:headerView];
for (int i = 1; i < 7; i++) {
UIButton * button = [[UIButton alloc] init];
button.tag = i+10;
button.titleLabel.font = [UIFont boldSystemFontOfSize:12];
[button setTitle:[NSString stringWithFormat:#"but0%d",i] forState:UIControlStateNormal];

button.translatesAutoresizingMaskIntoConstraints = NO;

button.enabled = YES;
button.userInteractionEnabled = YES;
[headerView addSubview:button];
}

NSDictionary * views = NSDictionaryOfVariableBindings(button01,button02,button03,button04,button05,button06);

[headerView addConstraints:constraintsV3];
[headerView addConstraints:constraintsV4];
[headerView addConstraints:constraintsV5];
[headerView addConstraints:constraintsV6];
[headerView addConstraints:constraintsH1];
return container;
}
i have not find the reason
anyone could help me?
i also add some UISwipeGestureRecognizer into UIView2
thank u

Answer 1

Thank u Guys
i got the solution
reason is that
[button addTarget:NULL action:#selector(click:) forControlEvents:UIControlEventTouchUpInside];
i set target NULL, and write click: in the same file, but actually i get the table from the main controller, so when i click button, xcode will find click: in the main controller, then can not find, so no responsibility.
after i set target self or write click: in main controller
it works
