这个相比定位简单, 还要引这个头文件, 但是, 不涉及定位, 只是对地址翻译成经纬度, 不用locationManager, info.plist也不需要添加什么
#import <CoreLocation/CoreLocation.h>
然后添加输入地址的textField, 显示经纬度的label各一个, 还有一个开始编译的按钮
然后在按钮点击事件里面写这些, 就完事啦
- (void)beginLocate:(UIButton *)button{
CLGeocoder *myGeocoder = [[CLGeocoder alloc] init];
[myGeocoder geocodeAddressString:_textField.text completionHandler:^(NSArray *placemarks, NSError *error) {
if ([placemarks count] > 0 && error == nil)
{
NSLog(@"Found %lu placemark(s).", (unsigned long)[placemarks count]);
CLPlacemark *firstPlacemark = [placemarks objectAtIndex:0];
NSLog(@"Longitude = %f", firstPlacemark.location.coordinate.longitude);
NSLog(@"Latitude = %f", firstPlacemark.location.coordinate.latitude);
_labelOfLonitude.text = [NSString stringWithFormat:@"经度: %lf", firstPlacemark.location.coordinate.longitude];
_labelOfLatitude.text = [NSString stringWithFormat:@"纬度: %lf", firstPlacemark.location.coordinate.latitude];
}
else if ([placemarks count] == 0 && error == nil)
{
NSLog(@"Found no placemarks.");
}
else if (error != nil)
{
NSLog(@"An error occurred = %@", error);
}
}];
}
