郵件、短信、相機、圖庫的使用
－.首先導入MessageUI.framework框架
二.導入頭文件#import
和代理方FMailComposeViewControllerDelegate,
MFMessageComposeViewControllerDelegate,UIImagePickerControllerDelegate,UINavigationControllerDelegate
三. .h文件
#import
#import
@interface ViewController : UIViewController
@property (strong, nonatomic) IBOutlet UIButton *Email;
@property (strong, nonatomic) IBOutlet UIButton *note;
@property (strong, nonatomic) IBOutlet UIButton *camera;
@property (strong, nonatomic) IBOutlet UIButton *mapDepot;
- (IBAction)mailDelivery:(id)sender;
- (IBAction)noteDelivery:(id)sender;
- (IBAction)useTheCamera:(id)sender;
- (IBAction)galleryUse:(id)sender;
四. .m文件
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
UIImageView *imageView = [[UIImageView alloc] init];
imageView.frame = CGRectMake(100, 20, 120, 120);
imageView.backgroundColor = [UIColor greenColor];
imageView.tag = 101;
[self.view addSubview:imageView];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
//發送郵件
- (IBAction)mailDelivery:(id)sender {
// 判斷設備是否是否可以發送郵件
Class mailClass = (NSClassFromString(@"MFMailComposeViewController"));
NSString * feedbackMsg;
if (!mailClass) {
feedbackMsg = @"當前系統版本不支持應用內發送郵件功能";
UIAlertView *alertView =
[[UIAlertView alloc] initWithTitle:@"提示"
message:feedbackMsg
delegate:nil
cancelButtonTitle:@"確定"
otherButtonTitles:nil];
[alertView show];
}else if(![mailClass canSendMail])
{
feedbackMsg = @"您沒有設置郵件賬戶";
UIAlertView *alertView =
[[UIAlertView alloc] initWithTitle:@"提示"
message:feedbackMsg
delegate:nil
cancelButtonTitle:@"確定"
otherButtonTitles:nil];
[alertView show];
}else{
[self sendFeedBackMail];
}
}
//發送短信
- (IBAction)noteDelivery:(id)sender {

}
}
//使用相機功能
- (IBAction)useTheCamera:(id)sender {
// UIImagePickerControllerCameraDeviceRear 後置攝像頭
// UIImagePickerControllerCameraDeviceFront 前置攝像頭
BOOL isCamera = [UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceRear];

return ;
}

}
//使用圖庫

}
#pragma mark--------------使用相機----------------
// 選中照片
