Even when I just use the Window-based application template, which does literally nothing, instruments (activity monitor) says my application's process is using 8.14MB of Real Memory! Even with this method:
void report_memory(void) {
struct task_basic_info info;
mach_msg_type_number_t size = sizeof(info);
kern_return_t kerr = task_info(mach_task_self(),
TASK_BASIC_INFO,
(task_info_t)&info,
&size);
if( kerr == KERN_SUCCESS ) {
NSLog(@"Memory in use (in bytes): %u", info.resident_size);
} else {
NSLog(@"Error with task_info(): %s", mach_error_string(kerr));
}
}
Its still ~8.14 MB! So it seems that instruments is right, but why would a UIWindow take up that much memory??
