Apple 在加载仅包含视图和背景颜色的笔尖时设法让我的应用程序崩溃。我似乎无法在我的设备上遇到崩溃。可能是内存问题还是我在代码中做了一些愚蠢的事情？报告和代码附在下面：

我在视图控制器中使用的代码：
#import "ThemesPopOverViewController.h"
@interface ThemesPopOverViewController ()
@end
@implementation ThemesPopOverViewController
@synthesize tableView;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
themes = [[NSArray alloc] initWithObjects:kRegexHighlightViewThemeArray];
self.tableView = nil;
self.tableView = [[UITableView alloc] initWithFrame:CGRectMake(20, 0, self.view.frame.size.width - 40, 350)];
[self.tableView setBackgroundColor:[UIColor clearColor]];
[self.tableView setDelegate:self];
[self.tableView setDataSource:self];
[self.view addSubview:self.tableView];
int item = [themes indexOfObject:theDelegate.codeView.currentTheme];
NSIndexPath *indexPath = [NSIndexPath indexPathForItem:item inSection:0];
[self.tableView selectRowAtIndexPath:indexPath animated:YES scrollPosition:UITableViewScrollPositionNone];
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1; //count of section
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
//NSLog(@"%d",themes.count);
return [themes count]; //count number of row from counting array hear cataGorry is An Array
}
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *MyIdentifier = @"MyIdentifier";
UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:MyIdentifier];
UIView *bgColorView = [[UIView alloc] init];
[bgColorView setBackgroundColor:[UIColor colorWithRed:25/255.0f green:185/255.0f blue:152/255.0f alpha:1.0f]];
[cell setSelectedBackgroundView:bgColorView];
}
[cell.textLabel setFont:[UIFont fontWithName:@"Helvetica" size:16]];
cell.textLabel.text = [themes objectAtIndex: indexPath.row];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
NSLog(@"%d", indexPath.row);
[theDelegate.codeView setHighlightThemeFromString:[themes objectAtIndex:indexPath.row]];
[theDelegate removePop];
}
@end
H 文件：
#import <UIKit/UIKit.h>
#import "AppDelegate.h"
@interface ThemesPopOverViewController : UIViewController <UITableViewDataSource, UITableViewDelegate>{
NSArray *themes;
}
@property (nonatomic, retain) UITableView *tableView;
