我在 iPhone 应用程序中工作,使用 UITableView 开发我的应用程序。我有 3 个部分,每个部分有 1 行,当用户在 Section1 中按下 UIButton 调用 B1 方法以在此表视图中添加一个部分和行时。它工作正常。
我试图添加动画(添加更多的部分和行)。
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.2];
但是为所有行和部分设置动画,但我想在添加部分和行中添加动画。如何处理这个请帮助我?
提前致谢
我试过这个:
- (void)viewDidLoad
{
[super viewDidLoad];
ExpandActive = NO;
self.title=@"Expand Tables";
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
if(ExpandActive == YES)
{
return 4;
}
else
{
return 3;
}
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return 1;
}
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{
if(ExpandActive == YES)
{
if(section == 0)
{
return @"Header1";
}
else if(section == 1)
{
return @"Header1";
}
else if(section == 2)
{
return @"Header1";
}
else if(section == 3)
{
return @"Header1";
}
}
else
{
if(section == 0)
{
return @"Header1";
}
else if(section == 1)
{
return @"Header1";
}
else if(section == 2)
{
return @"Header1";
}
}
}
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
return 30;
