邮件、短信、相机、图库的使用
－.首先导入MessageUI.framework框架
二.导入头文件#import<MessageUI/MessageUI.h>和代理方FMailComposeViewControllerDelegate,
MFMessageComposeViewControllerDelegate,UIImagePickerControllerDelegate,UINavigationControllerDelegate
三. .h文件
#import <UIKit/UIKit.h> #import <MessageUI/MessageUI.h> @interface ViewController : UIViewController<MFMailComposeViewControllerDelegate,MFMessageComposeViewControllerDelegate,UIImagePickerControllerDelegate,UINavigationControllerDelegate> @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.
}
//发送邮件
- (IBAction)mailDelivery:(id)sender {
// 判断设备是否是否可以发送邮件
Class mailClass = (NSClassFromString(@"MFMailComposeViewController"));
NSString * feedbackMsg;
if (!mailClass) {
feedbackMsg = @"当前系统版本不支持应用内发送邮件功能";
UIAlertView *alertView =
[[UIAlertView alloc] initWithTitle:@"提示"
message:feedbackMsg
delegate:nil
cancelButtonTitle:@"确定"
otherButtonTitles:nil];
[alertView show];
}else if(![mailClass canSendMail])
{

UIAlertView *alertView =
[[UIAlertView alloc] initWithTitle:@"提示"
message:feedbackMsg
delegate:nil
cancelButtonTitle:@"确定"

}else{
[self sendFeedBackMail];
}
}
//发送短信
- (IBAction)noteDelivery:(id)sender {

}
//使用图库

#pragma mark--------------使用相机----------------
