Code implementation for iPhone Development

IPhone DevelopmentThe implementation of the Code is the content to be introduced in this article. Should you be interested in it? This article describes how to create a jiugongge bucket. Let's take a look at the details. Many people in CocoaChina are asking, but it's actually very simple.ImageThe Code is as follows.

:

The core is the two methods:

 
 

  
  
// Power by ieliwb.com
  
  
-(Void) viewDidLoad {
  
  
[Super viewDidLoad];
  
  
NSArray * imageNames = [NSArray arrayWithObjects:
  
  
@ "Ico_mobile.png ",
  
  
@ "Ico_idcard.png ",
  
  
@ "Ico_postcode.png ",
  
  
@ "Ico_flight.png ",
  
  
@ "Ico_translate.png ",
  
  
@ "Ico_phone.png ",
  
  
@ "Ico_car.png ",
  
  
@ "Ico_health.png ",
  
  
@ "Ico_bjxm.png", nil];
  
  
UIButton * Btn;
  
  
For (int I = 0; I <9; I ++ ){
  
  
CGRect frame;
  
  
Btn = [[UIButton buttonWithType: UIButtonTypeCustom] retain];
  
  
[Btn setImage: [UIImage imageNamed: [imageNames objectAtIndex: I] forState: UIControlStateNormal]; // set the button Image
  
  
Btn. tag = I;
  
  
Frame. size. width = 59; // you can specify the coordinate and size of a button.
  
  
Frame. size. height = 75;
  
  
Frame. origin. x = (I % 3) * (59 + 32) + 40;
  
  
Frame. origin. y = floor (I/3) * (75 + 24) + 40;
  
  
[Btn setFrame: frame];
  
  

  
  
[Btn setBackgroundColor: [UIColor clearColor];
  
  
[Btn addTarget: self action: @ selector (btnPressed :) forControlEvents: UIControlEventTouchUpInside];
  
  
[Self. view addSubview: Btn];
  
  
[Btn release];
  
  
}
  
  
}
  
  

  
  
// Response button event
  
  
-(Void) btnPressed :( id) sender {
  
  
UIButton * Btn = (UIButton *) sender;
  
  
Int index = Btn. tag;
  
  
Switch (index ){
  
  
Case 0:
  
  
If (mobileController = nil)
  
  
MobileController = [[MobileController alloc] init];
  
  
[Self. navigationController pushViewController: mobileController animated: YES];
  
  
Break;
  
  
// Several other controllers are similar
  
  
}
  
  
}
 
 

The following figure shows how to modify the jiugongge Background:

 
 

  
  
- (void)loadView {  
  
  
    UIImageView *contentView = [[UIImageView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];  
  
  
    [contentView setImage:[UIImage imageNamed:@"subview_9_bg.png"]];  
  
  
    [contentView setUserInteractionEnabled:YES];  
  
  
    self.view = contentView;  
  
  
    [contentView release];  
  
  
} 
 
 

UINavigationBar backgroundImageThis can be achieved as follows:

 
 

  
  
@implementation UINavigationBar (CustomImage)  
  
  
- (void)drawRect:(CGRect)rect {  
  
  
    UIImage *image = [UIImage imageNamed: @"top_bg.png"];  
  
  
    [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];  
  
  
}  
  
  
@end 
 
 

Summary:IPhone DevelopmentThe content of code implementation of jiugongge has been introduced. I hope this article will help you!
