我正在为iOS设备编写静态库。使用xcode 3.2.6，选择最新的iOS 4.3进行编译，并选择iOS 3.1.2进行部署。保持所有设置默认，Library正在使用多个框架，如安全性。
为了测试，我首先将此lib作为应用程序编写，并仅在int retVal = UIApplicationMain(argc, argv, nil, nil);之前从主文件调用函数。所以这一切都完美无缺。
Now if I added UI components and calling functions as per user select an option, my application starts crashing randomly or aborted abnormally.
Latest crash Log is as follows:

以下是代码：
- (int) getInfo
{
@try{
Field *f = [self gField:F_NAME];
int index = [self getFIndex:f];
return [f findValAtIndex:index]; <=== 609
}
@catch (NSException * e)
{
MpDebugTrace(@"Exception : <%@> %@", [e name], [e reason]);
@throw; // re-throws exception
}
return -1;
}
- (int) findValAtIndex:(int) idx
{
NSString *key = [NSString stringWithFormat:@"%d", idx];
// vals is NSMutableDictionary
NSNumber *valForKey = [vals objectForKey:key];
return [valForKey intValue];
}
