问题描述
我有一个 viewcontroller
,我想显示 3 个 tableviews
(因为内容和表格属性不同).如何在一个 viewcontroller
中为 3 个表添加这些委托方法?
I have a viewcontroller
in that i want to show 3 tableviews
(because the content and the table properties are different). How do i add these delegate methodes for 3 tables in one viewcontroller
?
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [array1 count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {}

那么,如果我想使用自定义 cell
将 uislider
添加到一个表格行,并且当我滑动该值时我想更改显示亮度,我该怎么办?
So what will i do if i want add a uislider
to one table row using custom cell
and when i slide the value i want to change the display brightness?
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
if (tableView == _displayThemes) {
return 1;
} else {
return 1;
}
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if(tableView==_displayThemes) {
return 1;
} else {
return 5;
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
if (tableView == _displayThemes) {
cell.textLabel.text = [displaytheme objectAtIndex:indexPath.row];
return cell;
} else {
cell.textLabel.text = [fontlist objectAtIndex:indexPath.row];
return cell;
}
}
- (IBAction)fontButton:(id)sender {
_fontList = [[UITableView alloc]init];
[self.view addSubview:_fontList];
[UIView animateWithDuration:1.5
delay:0
options: UIViewAnimationOptionTransitionCurlUp
animations:^{
_fontList.fram e= CGRectMake(0,800,320,200);
}
completion:^(BOOL finished){
_fontList.frame = CGRectMake(0,280,320,200);
}];
[_fontList reloadData];
}
- (IBAction)button:(id)sender {
_displayThemes = [[UITableView alloc]init];
[self.view addSubview:_displayThemes];
[UIView animateWithDuration:1.5
delay:0
options: UIViewAnimationOptionTransitionCurlUp
animations:^{
_displayThemes.frame=CGRectMake(0,800,320,200);
}
completion:^(BOOL finished){
_displayThemes.frame=CGRectMake(0,280,320,200);
}];
}
推荐答案
这和你用一个 table view 做的一样,但你应该检查当前正在使用哪个 tableview.
It will be the same as you do it with one table view, but you should check which tableview is currently using.
myTableView1.dataSource = self;
...
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
if (tableView == myTableView1) {
// your code 1
}
else
if (tableView == myTableView2) {
// your code 2
}
else
if (tableView == myTableView3) {
// your code 3
}
}
关于亮度:
关于 UISlider
它有 minimunValue
和 maximumValue
属性.
And about UISlider
it has minimunValue
and maximumValue
properties.
- (void) sliderChanged:(UISlider*)sender{
UISlider *slider = (UISlider*)sender;
[[UIScreen mainScreen] setBrightness:slider.value];
}
slider.tag = 1;
[cell addSubview:slider];
...
// when you need..
indexPath = [NSIndexPath indexPathForRow:myRow inSection:mySecion];
UISlider* slider = (UISlider*) [[self.tableView cellForRowAtIndexPath:indexPath] viewWithTag:1];
