iPhone等：如何判断设备是否有摄像头？

Question

版本3.1.3如果相关。

有这个建议现在可以运作，但将来会有效吗？

NSString *device = [UIDevice currentDevice].model;

if([device isEqualToString:@"iPhone"])

Answer 1

#define SOURCETYPE UIImagePickerControllerSourceTypeCamera

// does the device have a camera?
if ([UIImagePickerController isSourceTypeAvailable:SOURCETYPE]) {
  // if so, does that camera support video?
  NSArray *mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:SOURCETYPE];
  bool isA3GS = [mediaTypes containsObject:(NSString*)kUTTypeMovie];
}
