[英]how to check the condition for UIButtons in UITableview
I am having three button image in table view, I want to check the conditions between them.
我在表格视图中有三个按钮图像,我想检查它们之间的条件。 when I click the button 1 means background image change to blue colour.
当我单击按钮1时,表示背景图像变为蓝色。 at the same time I click the button 1 it will move to normal state white colour.
同时单击按钮1,它将变为正常状态的白色。 Same for another two buttons.
其他两个按钮相同。
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath![button3 condition][3]
{
static NSString *cellIdentifier = @"HistoryCell";
CustomizedCellView *cell = (CustomizedCellView *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[CustomizedCellView alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}
UIButton *button1;
button1 = [UIButton buttonWithType:UIButtonTypeCustom];
button1.frame = CGRectMake(80, 27, 36, 36);
[button1 setImage:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"l"ofType:@"png"]] forState:UIControlStateNormal];
button1.tag = 1;
[button1 addTarget:self action:@selector(radiobtn:) forControlEvents:UIControlEventTouchUpInside];
[button1 setSelected:true];
[cell.contentView addSubview:button1];
UIButton *button2;
button2 = [UIButton buttonWithType:UIButtonTypeCustom];
button2.frame = CGRectMake(160, 27, 36, 36);
[button2 setImage:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"e"ofType:@"png"]] forState:UIControlStateNormal];
button2.tag = 1;
[button2 addTarget:self action:@selector(radiobtn:) forControlEvents:UIControlEventTouchUpInside];
[button2 setSelected:true];
[cell.contentView addSubview:button2];
UIButton *button3;
button3 = [UIButton buttonWithType:UIButtonTypeCustom];
button3.frame = CGRectMake(240, 27, 36, 36);
[button3 setImage:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"v"ofType:@"png"]] forState:UIControlStateNormal];
button3.tag = 1;
[button3 addTarget:self action:@selector(radiobtn:) forControlEvents:UIControlEventTouchUpInside];
[button3 setSelected:true];
[cell.contentView addSubview:button3];
return cell;
}
My condition is: when button 1 is clicked means button 3 should not change. 我的条件是:单击按钮1时,意味着按钮3不应更改。 when button 3 is clicked means button 1 should not change.button 2 can select in both the condition.
当单击按钮3时,意味着按钮1不应更改。按钮2可以在两种情况下都选择。
- (void)radiobtn:(UIButton *)button
{
if(button.tag == 1)
{
[button setImage:[UIImage imageNamed:@"lblue.png"] forState:UIControlStateSelected];
}
if(button.tag == 2)
{
[button setImage:[UIImage imageNamed:@"eblue.png"] forState:UIControlStateSelected];
}
if(button.tag == 3)
{
[button setImage:[UIImage imageNamed:@"vblue.png"] forState:UIControlStateSelected];
}
}
can any one help me in coding. 谁能帮我编码。
First of all you can set different tag for each button's like 首先,您可以为每个按钮的样式设置不同的标签
button.tag == 1,
button.tag == 2,
button.tag == 3
And then after you can write your radiobtn
Action like this way.. 然后,您可以像这样编写
radiobtn
Action。
-(IBAction) radiobtn:(id)sender
{
UIButton *yourBtn = (UIButton *)[self.view viewWithTag:[sender tag]];
if(yourBtn.tag == 1) {
[yourBtn setImage:[UIImage imageNamed:@"lblue.png"] forState:UIControlStateSelected];
}
else if(yourBtn.tag == 2){
[yourBtn setImage:[UIImage imageNamed:@"eblue.png"] forState:UIControlStateSelected];
}
else{
[yourBtn setImage:[UIImage imageNamed:@"vblue.png"] forState:UIControlStateSelected];
}
}
U can set tags to button 您可以将标签设置为按钮
button1.tag=1;
button2.tag=2;
button3.tag=3; //instead of tag 1 for all buttons
Take reference for buttons as button1,button2,button3 globally.. 全局将按钮的引用作为button1,button2,button3。
NSLog(@"%@",[[sender superview] class]); //UITableViewCellContentView
NSLog(@"%@",[[[sender superview] superview] class]); //UITableViewCellScrollView
NSLog(@"%@",[[[[sender superview]superview]superview] class]); //UITableViewCell
- (void)radiobtn:(UIButton *)button
{
if(button.tag==1)
{
//handle
CustomizedCellView * cell = (CustomizedCellView*)[[[button superview]superview]superview];
if ([button.imageView.image isEqual:[UIImage imageNamed:@"lblue.png"]]) {
[button setImage:[UIImage imageNamed:@"lwhite.png"] forState:UIControlStateSelected];
}
for (UIButton *btn in cell.contentView.subviews) {
if (btn.tag==3) {
[btn setImage:[UIImage imageNamed:@"vwhite.png"] forState:UIControlStateSelected];
}
}
}
else if(button.tag==2)
{
//handle
if ([button.imageView.image isEqual:[UIImage imageNamed:@"eblue.png"]]) {
[button setImage:[UIImage imageNamed:@"ewhite.png"] forState:UIControlStateSelected];
}
}
else if(button.tag==3)
{
//handle
CustomizedCellView * cell = (CustomizedCellView*)[[[sender superview]superview]superview];
if ([button.imageView.image isEqual:[UIImage imageNamed:@"vblue.png"]]) {
[button setImage:[UIImage imageNamed:@"vwhite.png"] forState:UIControlStateSelected];
}
for (UIButton *btn in cell.contentView.subviews) {
if (btn.tag==2) {
[btn setImage:[UIImage imageNamed:@"lwhite.png"] forState:UIControlStateSelected];
}
}
}
}
Hope it helps you...! 希望它可以帮助您...!
button1.tag=1; button2.tag=2; button3.tag=3;
-(void)radiobtn:(UIButton *)button
{
if(button.tag==1)
{
if(![button3 isSelected])
{
if([button1 isSelected])
button1.backgroundColor = [UIColor blueColor];
else
button1.backgroundColor = [UIColor whiteColor];
}
else
{
//No change
}
}
else if(button.tag==2)
{
if([button2 isSelected])
button2.backgroundColor = [UIColor blueColor];
else
button2.backgroundColor = [UIColor whiteColor];
}
else if(button.tag==3)
{
if(![button1 isSelected])
{
if([button3 isSelected])
button3.backgroundColor = [UIColor blueColor];
else
button3.backgroundColor = [UIColor whiteColor];
}
else
{
//No change
}
}
}
Can you have a try on this.. 你可以试一试吗..
Please check!! 请检查!! i have done same thing on my code.
我在代码上做了同样的事情。
