Google Map WIth Path
Google Map Example :
Hi Friends !!! Here I am Trying My Best To explain how Use Google Map In IOS. So,I think its may be very helpful to you, Because here I am Trying so simple & easy language and method so that everyone can understand it very quickly.
Here Google map Example using the API .... |
Note :-
Adding the "-ObjC" Linker Flag
- Select the project file from the project navigator on the far left side of the window.
- Select the target for where you want to add the linker flag.
- Select the "Build Settings" tab
- Choose "All" to show all Build Settings.
- Scroll down to the "Linking" section, and double-click to the right of where it says "Other Linking Flags".
- A box will appear, Click on the "+" button to add a new linker flag.
- Type "-ObjC" (no quotes) and press enter.
1) First Of all Include This File:
* import Google Map SDK Which Include
- Google Maps.Bundle
- Google Maps.Framework
2) Import Following Framework :
- SystemConfiguration.framework
- QuartzCore.framework
- OpenGLEZ.framework
- libz.dylib
- libicucore.dylib
- libc++.dylib
- ImageIO.framework
- GLKit.framework
- CoreText.framework
- CoreLocation.framework
- CoreData.framework
- AVFoundation.framework
- CoreGraphics.framework
- UIkit.framework
- GoogleMaps.framework
- Foundation.framework
3) Import Google Map Framework in
Appdelegate :
#import <GoogleMaps/GoogleMaps.h>
and also Declare a Key in didFinishLaunchingWithOptions Method :
[GMSServices provideAPIKey:@"AIzaSyB8b2r8hg8AbxR6ONlLLYP-UDZfYdOh1a8"];
4) Write Coding in Different View Controller
Which is Given Below :
* First View Controller (For Data Parse and Show In Table) :
FirstViewController.h :
#import <UIKit/UIKit.h>
#import "ViewController.h"
@interface FirstViewController : UIViewController
{

}

@property(strong,nonatomic)NSMutableArray *arrobj;
@end

#import "FirstViewController.h"
#import "Container.h"
@interface FirstViewController ()
@end
@implementation FirstViewController

}

NSString *strlong = [diclocation objectForKey:@"lng"];
data.stringlong = strlong;
NSString *strname = [subdic objectForKey:@"name"];
data.stringname = strname;
NSString *stradd = [subdic objectForKey:@"vicinity"];
data.stringadd = stradd;
[arrobj addObject:data];
}
[tblobj reloadData];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return arrobj.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
Container *data1 = [arrobj objectAtIndex:indexPath.row];
UITableViewCell *cell = [tblobj dequeueReusableCellWithIdentifier:@"cell"];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"];
}
cell.textLabel.text = data1.stringname;
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
Container *mydata = [arrobj objectAtIndex:indexPath.row];
UIStoryboard *story = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
viewobj = [story instantiateViewControllerWithIdentifier:@"ViewController"];
viewobj.strlat = mydata.stringlate;
viewobj.strlong = mydata.stringlong;
viewobj.strname = mydata.stringname;
viewobj.stradd = mydata.stringadd;
[self.navigationController pushViewController:viewobj animated:YES];
