朋友们,

因为我们在android中有google api的地理编码器getfromlocation(locationname,maximumResults)功能.

我没有在iphone sdk中看到这样的功能来从城市名称获取经度和纬度值.

任何人都指导我如何实现这一功能？任何帮助,将不胜感激.

我需要与CA BASIC ANIMATION同时旋转和移动相同的图像,在iphone sdk中是否有任何出路

任何帮助将受到高度赞赏

这是我的代码

 imgview = (UIImageView *)[self.view viewWithTag:imagenumber];
 CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@"position"];
 anim.fromValue  = [NSValue valueWithCGPoint:CGPointMake(160 + x_movefrom, 240 + y_movefrom)];
 anim.toValue    = [NSValue valueWithCGPoint:CGPointMake(160 + x_moveto, 240 + y_moveto)];
 anim.duration   = 2;
 anim.removedOnCompletion = YES;

 //imgview = (UIImageView *)[self.view viewWithTag:imagenumber];

CABasicAnimation *opacityAnim = [CABasicAnimation animationWithKeyPath:@"alpha"];
opacityAnim.fromValue = [NSNumber numberWithFloat:1.0];
opacityAnim.toValue = [NSNumber numberWithFloat:0.0];
opacityAnim.removedOnCompletion = NO;

CAAnimationGroup *animGroup = [CAAnimationGroup animation];
animGroup.animations = [NSArray arrayWithObjects:opacityAnim,anim, nil];
animGroup.duration = 2;
animGroup.delegate = self;
animGroup.removedOnCompletion = NO; …
