Question

chey I am working on a ipod and i wanted to make sure that the device supports multitasking for some features to run… is there any way? I tried with this –

   UIDevice* device = [UIDevice currentDevice];
   BOOL backgroundSupported = NO;
   backgroundSupported = device.multitaskingSupported;

but the above function not working properly its crashing on some devices… any idea?

Answer 1

Seems like you are using device.multitaskingSupported where it is not supported…
You should check if multitaskingSupported is available on device or in OS before using ..

You should do something like this –

- (BOOL) isMultitaskingCapable
{
    UIDevice* device = [UIDevice currentDevice];
    BOOL backgroundSupported = NO;
    if ([device respondsToSelector:@selector(isMultitaskingSupported)])
        backgroundSupported = device.multitaskingSupported;

    return backgroundSupported;
}
