1、分享到Facebook连接。http://m.facebook.com/sharer.php?u=URL&t=标题
2、移除ABPeoplePickerNavigationController右边的Cancel按钮
ABPeoplePickerNavigationController *picker = [ init]; picker.delegate = self;.................- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated { // Here we want to remove the 'Cancel' button, but only if we're showing // either of the ABPeoplePickerNavigationController's top two controllers viewController.navigationItem.rightBarButtonItem = nil;}

3.ios multipart request related code:
- (void) uploadPicture{ UIImage *img = ; NSData *imageData = UIImageJPEGRepresentation(img, 90); //Here i tried 2 ways of getting the data for uploading, but both don't work. // create the URL NSURL *postURL = ; // create the connection NSMutableURLRequest *postRequest = ; // change type to POST (default is GET) ; // just some random text that will never occur in the body NSString *stringBoundary = @"0xKhTmLbOuNdArY---This_Is_ThE_BoUnDaRyy---pqo"; // header value, user session ID added NSString *headerBoundary = ; // set header ; // create data NSMutableData *postBody = ; // text part dataUsingEncoding:NSUTF8StringEncoding]]; dataUsingEncoding:NSUTF8StringEncoding]]; ]; ]; // media/image part dataUsingEncoding:NSUTF8StringEncoding]]; dataUsingEncoding:NSUTF8StringEncoding]]; ]; ]; ]; // final boundary dataUsingEncoding:NSUTF8StringEncoding]]; NSString *s = [ initWithData:postBody encoding:NSASCIIStringEncoding]; NSLog(@"%@", s); // add body to post ; // pointers to some necessary objects NSURLResponse* response; NSError* error; // synchronous filling of data from HTTP POST response NSData *responseData = ; completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) { if (error) { NSLog(@"Error: %@", ); } // convert data into string NSString *responseString = [ initWithBytes: length: encoding:NSUTF8StringEncoding]; // see if we get a welcome result NSLog(@"%@", responseString); }];}

4.Popup 效果弹出视图
CGAffineTransform transform = CGAffineTransformIdentity; ; ; } completion:^(BOOL finished) { ; } completion:^(BOOL finished) { ; } completion:^(BOOL finished) { //do nothing }]; }]; }];
5.上下摇晃动画效果
CALayer*viewLayer=; CABasicAnimation*animation=; animation.duration=0.1; animation.repeatCount = 4; animation.autoreverses=YES; animation.fromValue=; animation.toValue=; ;
6.检查ARC的宏
#if !__has_feature(objc_arc) ;#endif
