請解釋爲什麼如果您投票。 我的UIView的一個子類實現代碼如下節頭UIview調用autorelease的子類會導致崩潰
@interface ContactSectionHeaderView()
@property (nonatomic, retain) IBOutlet UILabel *headerTitle;
@end
@implementation ContactSectionHeaderView
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if(self){
id rootView = [[self class] viewSizedForDevice];
[rootView setFrame:frame];
self = rootView;
}
return self;
}
+ (id) viewSizedForDevice {
UINib* nib = [self nib];
NSArray * nibObjects = [nib instantiateWithOwner:self options:nil];
NSAssert2(([nibObjects count] > 0) &&
[[nibObjects objectAtIndex:0] isKindOfClass:[self class]],
@"Nib '%@' does not appear to contain a value %@",
[self nibName], NSStringFromClass([self class]));
id rootView = nibObjects[0];
return rootView;
}
+(UINib*)nib {
NSBundle * classBundle = [NSBundle bundleForClass:[self class]];
UINib * nib = [UINib nibWithNibName:[self nibName] bundle:classBundle];
return nib;
}
+ (NSString *)nibName {
return [self viewIdentifier];
}
+ (NSString *)viewIdentifier {
static NSString* _viewIdentifier = @"ContactSectionHeaderView";
_viewIdentifier = NSStringFromClass([self class]);
return _viewIdentifier;
}
-(void)setTitle:(NSString *)title {
self.headerTitle.text = [NSString stringWithFormat:@"%@",title];
}
- (void)dealloc {
self.headerTitle = nil;
[super dealloc];
}
@end
我在- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
ContactSectionHeaderView *sectionHeader = [[[ContactSectionHeaderView alloc] initWithFrame:[tableView rectForHeaderInSection:section]] autorelease];
這autorelease
使用這樣導致飛機失事的原因。如果我刪除了autorelease,那麼它完美的工作。我如何解決崩潰?
你的項目是ARC還是非ARC? –
您不需要使用'autorelease',因爲現在所有東西都是弧形的,它會自動完成,您正在使用石器時代代碼。 – iphonic
我的項目在非ARC @AshishThakkar – tausun
