Custom Image View in iPhone

Introduction

In this article I will create an Empty View application. Here I will implement an Image View in iPhone. To do that we write code for the appdelegate.m Objective-C class.

To understand it we use the following.

Step 1

Open XCode by double-clicking on it.

Step 2

Create a New XCode Project by clicking on it.

Step 3

Now Select Empty View Application and click on Next.

Step 4

Now provide your Product Name and Company Identifier.

Step 5

Select the location where you want to save your project and click on Create.

Step 6

Now here we write the code.

AppDelegate.h

#import <UIKit/UIKit.h>
@interface testviewAppDelegate : UIResponder <UIApplicationDelegate>
@property (strong, nonatomic) UIWindow *window;
@end

AppDelegate.m

#import "testviewAppDelegate.h"
@implementation testviewAppDelegate
- (void)dealloc
{
[_window release];
[super dealloc];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
self.window.backgroundColor = [UIColor whiteColor];
CGRect myimagerect = CGRectMake(0, 0, 320, 480);
UIImageView *myimage = [[UIImageView alloc]initWithFrame:myimagerect];
[myimage setImage:[UIImage imageNamed:@"Sachin.png"]];
myimage.opaque = YES;
[self.window addSubview:myimage];
[myimage release];
[self.window makeKeyAndVisible];
return YES;
}
@end

Step 7

Finally we click on the run button to show the output.

Step 8

Output 1 in iPhone:
