翻页过渡效果 经纬度 NSData类型的数据转换成NSString

- (IBAction)backToMenus:(id)sender {

    CATransition *transition = [CATransition animation];

    transition.duration = 0.5;

    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];

    transition.type = kCATransitionFade;

    transition.delegate = self;

    [self.view.superview.layer addAnimation:transition forKey:nil];

    [self.view removeFromSuperview];

在iPhone中设置googlemap的经纬度

CLLocationCoordinate2D centerCoordinate;

centerCoordinate.latitude = 39.9097;

centerCoordinate.longitude = 105.3476;

MKCoordinateSpan span;

span.latitudeDelta = 30;

span.longitudeDelta = 30;

MKCoordinateRegion region;

region.center = centerCoordinate;

region.span = span;

[mapview setRegion:region animated:TRUE];

16、将NSData类型的数据转换成NSString：

1

NSString *theXML = [[NSString alloc] initWithBytes: [webData mutableBytes] length:[webData length] encoding:NSUTF8StringEncoding]; //webData为NSData类型

17、将NSString类型的数据转换成NSData：

1

NSData *webData = [NSMutableData dataWithBytes:[theXML UTF8String] length:[theXML length]];; //theXML为NSString类型
