我在这里遇到一个难题,不管感谢,我的意思是任何帮助=)

我是一名经验丰富的开发人员,我是Objective-C/iPhone/Cocoa的新手.

我想创建一个类控制器,我可以将NSMutableArray作为参数传递.

然后,我们有:

selTimeIntController = [[SingleSelectPickerViewController alloc] initWithSettings: listOfIntervals :kAlarmIntervalStr :myDataHolder.alarmInterval];
[self.navigationController pushViewController: selTimeIntController animated: YES];
[selTimeIntController release];

这个listOfIntervals是一个已经是alloc/init的NSMutableArray*.

在我的SingleSelectPickerViewController上,我们有:

-(id)initWithSettings:(NSMutableArray*)sourceArray :(NSString*)viewCurrentValue :(NSString*)viewTitle {

    if(self = [self initWithNibName: kNibName bundle: [NSBundle mainBundle]]) {

            listOfIntervals = [NSMutableArray arrayWithArray: (NSMutableArray*)sourceArray];
            currentValue    = [[NSString alloc] initWithString: viewCurrentValue];
            title           = [[NSString alloc] initWithString: viewTitle];
    }

    return self;
}

通过调试,我能够在SingleSelectPickerViewController上看到我的listOfIntervals.

这里我们有SingleSelectPickerViewController'dealloc:

- (void)dealloc {
    [super dealloc];

    [listOfIntervals release];
    [currentValue    release];
    [title           release];
}

但是,每次我实例化我的SingleSelectViewController时,我都会收到一个带有以下堆栈的EXEC_BAD_ADDRESS:

#0  0x96132688 in objc_msgSend ()
#1  0x00003ee2 in -[SingleSelectPickerViewController tableView:numberOfRowsInSection:] …
