how to get all button tag values from a group of buttons
hi i am new to iphone. what i did is creating group of buttons in the view.My code is as fallows
- (void)mymethod1 {
UIView *view = [[UIView alloc]initWithFrame:[[UIScreen mainScreen]bounds]];
int row = 0;
int column = 0;
for (int i=6; i<_images.count; i++) {
buttonimage = [UIButton buttonWithType:UIButtonTypeCustom];
buttonimage.frame = CGRectMake(column*60+5, row*60+5, 70,70);
[buttonimage setImage:[UIImage imageNamed:[_images objectAtIndex:i]] forState:UIControlStateNormal];
buttonimage.tag = i;
[buttonimage addTarget:self
action:@selector(buttonClicked:)
forControlEvents:UIControlEventTouchUpInside];
buttonimage.tag = i;
[view addSubview:buttonimage];
if (column == 4) {
column = 0;
row++;
} else {
column++;
}
}
self.view = view;
[ view release];
}
it works fine. but when ever i call the all the buttons in any other functions it gets last button only for eg:
- (void)mymethod2 {
NSLog(@"button value %d",buttonimage.tag);
}
"it get in console button value 5".but i need to get all the button tag values in mymethod2. how can i get all button tag values.Please开发者_如何学C post some code.Thank u in advance.
You need to iterate all the subviews of the current view and then check to see if it's a button before casting, something like this
for (UIView* view in [self.view subviews]) {
if([view isKindOfClass:[UIButton class]]){
UIButton *btn = (UIButton*)view;
NSLog(@"button value %d", btn.tag);
}
}
All button tag values:-
for(int i=0;i<3;i++){
UIButton *theButton=[[UIButton alloc]init];
theButton.tag=i;
//set their selector using add selector
[theButton addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchDown];
//set their frame color title or image
}
-(void)buttonClicked:(UIButton *)inButton{
int tags=inbutton.tag;
}
UIButton *BtnTmp=sender;
if([BtnTmp tag])
[BtnTmp setImage:[UIImage imageNamed:@"check.png"] forState:UIControlStateNormal];
else
[BtnTmp setImage:[UIImage imageNamed:@"uncheck.png"] forState:UIControlStateNormal];
BtnTmp.tag=!BtnTmp.tag;
