uitableview repoaddata 호출에서 exc_bad_access

Question

나는이 머리카락을이 머리 위로 끌어 당기는 시점에왔다. UitableView의 ReloadData를 호출 할 때 EXC_BAD_ACCESS를 계속받습니다. 여기에 당신을위한 토대를 마련하겠습니다.

MainViewController.h

#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>

@class iPROSAppDelegate;

@interface MainViewController : UIViewController <UIScrollViewDelegate, UITableViewDelegate, UITableViewDataSource> {
 iPROSAppDelegate *parent;

 ...

 NSMutableArray *contentSeqList;
 UITableView *contentSeqTable;
}

@property (nonatomic, retain) IBOutlet iPROSAppDelegate *parent;
...
@property (nonatomic, retain) NSMutableArray *contentSeqList;
@property (nonatomic, retain) IBOutlet UITableView *contentSeqTable;
...
- (IBAction)changeMainView:(id)sender;

@end

MainViewController.m

- (IBAction)changeMainView:(id)sender{
    //do logs to make sure we get here and grab an NSDictionary object from another class
 NSLog(@"got to a change of main view");
 NSDictionary *myContentSequences = [[parent csList] grabCSListandReturnJSON:[sender tag]];
 NSLog(@"got cs list for tag %@: %@", [sender currentTitle], myContentSequences);

    //set up table view
 contentSeqTable = [[UITableView alloc] initWithFrame:CGRectMake(40, 20, 240, 300) style:UITableViewStyleGrouped];
 contentSeqTable.separatorStyle = UITableViewCellSeparatorStyleSingleLine;
 [contentSeqTable setDelegate:self];
 [contentSeqTable setDataSource:self];
 NSLog(@"delegate: %@, data source: %@", [contentSeqTable delegate], [contentSeqTable dataSource]);
 contentSeqList = [[NSMutableArray alloc] init];

    //populate nsmutablearray contentseqlist using the nsdictionary mycontentsequences
 for (id dashboard in [myContentSequences objectForKey:@"dashboards"]){
  if ([dashboard objectForKey:@"error"] == nil){
   for (id contentsequence in [dashboard objectForKey:@"contentSequences"]){
    [contentSeqList addObject:[contentsequence objectForKey:@"name"]];
    NSLog(@"added object to content sequence list: %@", [contentsequence objectForKey:@"name"]);
   }
  }
 }
 [contentSeqTable reloadData];
 ...
}

ChangemainView는 기본보기에서 버튼을 클릭하면 호출됩니다. UitableView의 대의원 방법은 다음과 같습니다. NSLOG는이 방법의 첫 번째 줄이지만 EXC_BAD_ACCESS 전에 콘솔 로그에 표시되지 않습니다.

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
 NSLog(@"content seq list count: %@", [contentSeqList count]);
 return [contentSeqList count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ 
 NSLog(@"setting up the cells");
 NSUInteger index = [indexPath indexAtPosition:1];

 NSString *myId = @"id";
 if (tableView.editing) myId = @"idE";

 UILabel *name;

 UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:myId];

 if (cell == nil){
  cell = [[[UITableViewCell alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 20)  reuseIdentifier:myId] autorelease];

  float width = 260;
  if (tableView.editing) width = 240;

  name = [[[UILabel alloc] initWithFrame:CGRectMake(45, 1, width, 53)] autorelease];
  [name setBackgroundColor:[UIColor clearColor]];
  [name setTextColor:[UIColor blackColor]];
  [name setFont:[UIFont fontWithName:@"Helvetica" size: 18]];
  [name setAdjustsFontSizeToFitWidth:YES];
  [name setMinimumFontSize:11];
  [name setNumberOfLines:2];

  name.tag = 1;

  [cell.contentView addSubview:name];

 }
 else{
  name = (UILabel *)[cell.contentView viewWithTag:1];
 }

 if ([tableView indexPathForSelectedRow]){
  if (indexPath == [tableView indexPathForSelectedRow]){  
   [name setTextColor:[UIColor whiteColor]];
  }
  else{
   [name setTextColor:[UIColor blackColor]];
  }
 }
 else{
  [name setTextColor:[UIColor blackColor]];
 }

 [name setText:[contentSeqList objectAtIndex:index]];

 return cell;
}

대의원 방법은 동일한 클래스 MainViewController의 일부입니다. 또한 uitableview가 ReloadData 직전에 NSLOG를 통해 NIL이 아니 었는지 확인했습니다. 나는 여기서 작은 것을 놓치고 있어야한다는 것을 안다. 모든 제안은 대단히 감사 할 것입니다. 감사!

Answer 1

언제 콜 스택을 보여줄 수 있습니까? EXC_BAD_ACCESS 발생합니까?

btw,

NSUInteger index = [indexPath row];

보다 훨씬 더 읽기 쉽습니다

NSUInteger index = [indexPath indexAtPosition:1];
