有这样的控制,我真的很感激：
github link的问题是,现在我有一种情况,当我需要打开一行,所有以前的应该关闭,我只能有一个打开的行当时.
由于我对xcode不是很有经验,我需要一些关于我应该在哪里开始的信息,以及必要的步骤来使代码按照我现在的方式工作.
我设法做了一些测试,但不是一个可行的解决方案,这里是我现在所拥有的：
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
NSInteger row = indexPath.row;
if (indexPath.section == 0) {
NSLog(@"indexPath1 = %i",selectedRow);
NSDictionary *d = [self.firstForTable objectAtIndex:indexPath.row];
if([d valueForKey:@"Objects"]) {
NSArray *ar = [d valueForKey:@"Objects"];
NSUInteger count = indexPath.row +1;
NSMutableArray *arCells = [NSMutableArray array];
for(NSDictionary *dInner in ar ) {
[arCells addobject:[NSIndexPath indexPathForRow:count inSection:0]];
[self.firstForTable insertObject:dInner atIndex:count++];
}
[tableView insertRowsAtIndexPaths:arCells withRowAnimation:UITableViewRowAnimationLeft];
}
else {
NSLog(@"Leave Element:::%@ %@|",[d valueForKey:@"name"],[d valueForKey:@"book"]);
}
if (selectedRow == row) {
NSLog(@"selectedRow2 = %i",selectedRow);
NSDictionary *d=[self.firstForTable objectAtIndex:selectedRow];
if([d valueForKey:@"Objects"]) {
NSArray *ar = [d valueForKey:@"Objects"];
[self miniMizefirstsRows:ar];
}
selectedRow = -1;
return;
}
if (selectedRow >= 0) {
NSLog(@"selectedRow3 = %i",selectedRow);
NSDictionary *d=[self.firstForTable objectAtIndex:selectedRow];
if([d valueForKey:@"Objects"]) {
NSArray *ar = [d valueForKey:@"Objects"];
[self miniMizefirstsRows:ar];
}
selectedRow = row;
}
selectedRow = row;
[tableView beginUpdates]; [tableView endUpdates];
}
if (indexPath.section == 1) {
NSDictionary *d = [self.secondForTable objectAtIndex:indexPath.row];
if([d valueForKey:@"Objects"]) {
NSArray *ar = [d valueForKey:@"Objects"];
BOOL isAlreadyInserted=NO;
for (NSDictionary *dInner in ar) {
NSInteger index = [self.secondForTable indexOfObjectIdenticalTo:dInner];
isAlreadyInserted = (index > 0 && index != NSIntegerMax);
if (isAlreadyInserted) break;
}
if (isAlreadyInserted) {
[self miniMizeSecondsRows:ar];
}
else {
NSUInteger count = indexPath.row+1;
NSMutableArray *arCells = [NSMutableArray array];
for (NSDictionary *dInner in ar ) {
[arCells addobject:[NSIndexPath indexPathForRow:count inSection:1]];
[self.secondForTable insertObject:dInner atIndex:count++];
}
[tableView insertRowsAtIndexPaths:arCells withRowAnimation:UITableViewRowAnimationLeft];
}
}
else {
NSLog(@"Leave Element:::%@ %@|",[d valueForKey:@"book"]);
}
}
}
提前致谢.
解决方法
更新：
Expandable Rows JSON是您的项目,自动崩溃为所有行工作.
另外检查Expandable Rows,我打了这个项目来帮助诺瓦拉,并改进它.现在正在为所有部分工作,除了嵌套的行.
第一步
跟踪每个部分打开的行.当然这可以通过使用多个部分的打开的NSArray来完成.
@interface RootViewController : UITableViewController {
NSInteger tabOpened_1;
NSInteger tabOpened_2;
}
第二步
接下来使用“-1”值初始化那些,没有打开的选项卡.
- (void)viewDidLoad
{
........
[self.firstForTable addobjectsFromArray:self.firstArray];
tabOpened_1 = -1;
[self.secondForTable addobjectsFromArray:self.secondarray];
tabOpened_2 = -1;
}
第三步
更改didSelectRowAtIndexPath
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
if (indexPath.section==0) {
NSDictionary *d=[self.firstForTable objectAtIndex:indexPath.row];
if([d valueForKey:@"produtos"]) {
if (tabOpened_1 == -1) {
NSLog(@"No tab opened in first section");
tabOpened_1 = indexPath.row;
} else if(tabOpened_1 != indexPath.row && tabOpened_1 > indexPath.row){
NSDictionary *d_ = [self.firstForTable objectAtIndex:tabOpened_1];
NSArray *ar_ = [d_ valueForKey:@"produtos"];
[self miniMizefirstsRows:ar_];
tabOpened_1 = indexPath.row;
}
NSArray *ar=[d valueForKey:@"produtos"];
BOOL isAlreadyInserted=NO;
for(NSDictionary *dInner in ar ){
NSInteger index=[self.firstForTable indexOfObjectIdenticalTo:dInner];
isAlreadyInserted=(index>0 && index!=NSIntegerMax);
if(isAlreadyInserted) break;
}
if(isAlreadyInserted) {
[self miniMizefirstsRows:ar];
} else {
NSUInteger count=indexPath.row+1;
NSMutableArray *arCells=[NSMutableArray array];
for(NSDictionary *dInner in ar ) {
[arCells addobject:[NSIndexPath indexPathForRow:count inSection:0]];
[self.firstForTable insertObject:dInner atIndex:count++];
}
[tableView insertRowsAtIndexPaths:arCells withRowAnimation:UITableViewRowAnimationLeft];
}
if (tabOpened_1 == -1) {
NSLog(@"No tab opened in first section");
tabOpened_1 = indexPath.row;
} else if(tabOpened_1 != indexPath.row && tabOpened_1 < indexPath.row){
NSDictionary *d_ = [self.firstForTable objectAtIndex:tabOpened_1];
NSArray *ar_ = [d_ valueForKey:@"produtos"];
[self miniMizefirstsRows:ar_];
tabOpened_1 = indexPath.row - [ar_ count];
tabOpened_1 = (tabOpened_1 < 0) ? indexPath.row : tabOpened_1;
}
} else {
NSLog(@"Leave Element:::%@ %@|",[d valueForKey:@"nome"],[d valueForKey:@"numeroConta"]);
}
for (int i=0; i < [[self.rowsPerSection objectAtIndex:indexPath.section] integerValue]; i++) {
NSDictionary *d_ = [self.secondForTable objectAtIndex:i];
NSArray *ar_ = [d_ valueForKey:@"produtos"];
[self miniMizeSecondsRows:ar_];
}
}
if (indexPath.section==1) {
if (tabOpened_2 == -1) {
NSLog(@"No tab opened in second section");
tabOpened_2 = indexPath.row;
} else if(tabOpened_2 != indexPath.row && tabOpened_2 > indexPath.row){
NSDictionary *d_ = [self.secondForTable objectAtIndex:tabOpened_2];
NSArray *ar_ = [d_ valueForKey:@"produtos"];
[self miniMizeSecondsRows:ar_];
tabOpened_2 = indexPath.row;
}
NSDictionary *d=[self.secondForTable objectAtIndex:indexPath.row];
if([d valueForKey:@"produtos"]) {
NSArray *ar=[d valueForKey:@"produtos"];
BOOL isAlreadyInserted=NO;
for(NSDictionary *dInner in ar ){
NSInteger index=[self.secondForTable indexOfObjectIdenticalTo:dInner];
isAlreadyInserted=(index>0 && index!=NSIntegerMax);
if(isAlreadyInserted) break;
}
if(isAlreadyInserted) {
[self miniMizeSecondsRows:ar];
} else {
NSUInteger count=indexPath.row+1;
NSMutableArray *arCells=[NSMutableArray array];
for(NSDictionary *dInner in ar ) {
[arCells addobject:[NSIndexPath indexPathForRow:count inSection:1]];
[self.secondForTable insertObject:dInner atIndex:count++];
}
[tableView insertRowsAtIndexPaths:arCells withRowAnimation:UITableViewRowAnimationLeft];
}
if (tabOpened_2 == -1) {
NSLog(@"No tab opened in second section");
tabOpened_2 = indexPath.row;
} else if(tabOpened_2 != indexPath.row && tabOpened_2 < indexPath.row){
NSDictionary *d_ = [self.secondForTable objectAtIndex:tabOpened_2];
NSArray *ar_ = [d_ valueForKey:@"produtos"];
[self miniMizeSecondsRows:ar_];
tabOpened_2 = indexPath.row - [ar_ count];
tabOpened_2 = (tabOpened_2 < 0) ? indexPath.row : tabOpened_2;
}
} else {
//NSLog(@"Leave Element:::%@ %@|",[d valueForKey:@"book"]);
}
for (int i=0; i < [[self.rowsPerSection objectAtIndex:indexPath.section] integerValue]; i++) {
NSDictionary *d_ = [self.firstForTable objectAtIndex:i];
NSArray *ar_ = [d_ valueForKey:@"produtos"];
[self miniMizefirstsRows:ar_];
}
}
