Cocoa TouchでUIButtonを動的に作成するにはどうすればよいですか？

Answer 1

UIButton *myButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 
    myButton.frame = CGRectMake(20, 20, 200, 44); // position in the parent view and set the size of the button 
    [myButton setTitle:@"Click Me!" forState:UIControlStateNormal]; 
    // add targets and actions 
    [myButton addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside]; 
    // add to a view 
    [superView addSubview:myButton];

それは非常に簡単です

UIImage * buttonImage = [UIImage imageNamed：@ "タブバー - refresh.png"];

refresh = [UIButton buttonWithType:UIButtonTypeCustom]; 
refresh.frame = CGRectMake(frame values); 
[refresh setBackgroundImage:buttonImage forState:UIControlStateNormal]; 
[refresh addTarget:self action:@selector(refreshPressed:) forControlEvents:UIControlEventTouchUpInside];  
[self.view addSubview:refresh]; 

Answer 3

ここにコードがある...

UIButton *btnDone; 
btnDone = [UIButton buttonWithType:UIButtonTypeCustom]; 
[btnDone setFrame:CGRectMake(0, 0, 28, 29)]; 

// For setting an image to button.... 
[btnDone setImage:[UIImage imageNamed:@"done.png"] forState:UIControlStateNormal]; 
[btnDone setImage:[UIImage imageNamed:@"done_hover.png"] forState:UIControlStateHighlighted]; 

// Add target to button... 
[btnDone addTarget:self action:@selector(btnDoneAction:) forControlEvents:UIControlEventTouchUpInside]; 

//Method implementation.. 
-(void)btnDoneAction:(id)sender 
{ 
    //Your stuff.. 
} 

希望、これはあなたが....役立ちます:)

あなたがそのような何かを行うことができます。

int yOfs = 0; 
for (int index = 0; index<10; index++) { 
    UIButton *aButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
    [aButton setBackgroundImage:[UIImage imageNamed:@"buttonImage"] forState:UIControlStateNormal]; 
    [aButton setTitle:[NSString stringWithFormat:@"Button %d",index] forState:UIControlStateNormal]; 
    [aButton setFrame:CGRectMake(20, yOfs, 100, 50)]; 
    [aButton addTarget:self action:@selector(aButtonClicked:) forControlEvents:UIControlEventTouchUpInside]; 
    [aView addSubview:aButton]; 

    yOfs += 50; 
} 


- (IBAction)aButtonClicked:(id)sender 
{ 
    NSLog(@"Clicked on button with title %@",[sender titleLabel].text); 
}
