有没有办法nslog您的应用程序当前正在使用多少内存?

最佳答案

#import <mach/mach.h>


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 used: %u", info.resident_size); //in bytes
  } else {
    NSLog(@"Error: %s", mach_error_string(kerr));
  }
}
