Custom UIButton for Iphone

Question

I have an view in my App which has a number of buttons based on the number of items returned by the server. So if the server returns say 10 items, there should be 10 buttons

Answer 1

you can use individual class for custom Roundrect button which can be useful in whole project with your specific frame style as below

#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>
@interface CustomRoundRectButton : UIButton
@end


#import "CustomRoundRectButton.h"
@implementation CustomRoundRectButton
- (void)drawRect:(CGRect)rect
{
[[self layer] setMasksToBounds:YES];
[self.layer setCornerRadius:10.0f]; 
[self.layer setBorderColor:[UIColor grayColor].CGColor]; 
[self.layer setBorderWidth:1.0];
}
@end

In this you have to select button type custom and select its class as CustomRoundRectButton.

For Simple custom button we can use as below

-(UIBarButtonItem*)BackButton
{
UIButton*btn =  [UIButton buttonWithType:UIButtonTypeCustom];
[btn setImage:[UIImage imageNamed:@"back.png"] forState:UIControlStateNormal];
[btn setFrame:CGRectMake(0, 0, 30, 30)];
[btn addTarget:self action:@selector(actionBack) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem*barBtn = [[[UIBarButtonItem alloc] initWithCustomView:btn] autorelease];
return barBtn;
}

Answer 2

[sampleButton setFont:[UIFont boldSystemFontOfSize:20]]; 

setFont is now deprecated, use titleLabel.font property instead

sampleButton.titleLabel.font = [UIFont boldSystemFontOfSize:20];

Answer 3

Shouldn't you be calling initWithFrame: rect instead of:

    HopitalButton* hb = [[HopitalButton alloc] init];

Answer 4

You first start with a stretchable image with a border:

alt text http://grab.by/4lP

Then you make a button with the stretched image as the background and apply text.

INDEX_OFFSET = 82753; // random

UIButton *sampleButton = [UIButton buttonWithType:UIButtonTypeCustom];
[sampleButton setFrame:CGRectMake(kLeftMargin, 10, self.view.bounds.size.width - kLeftMargin - kRightMargin, 52)];
[sampleButton setTitle:@"Button Title" forState:UIControlStateNormal];
[sampleButton setFont:[UIFont boldSystemFontOfSize:20]];
[sampleButton setTag:<INDEX>+INDEX_OFFSET];
[sampleButton setBackgroundImage:[[UIImage imageNamed:@"redButton.png"] stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0] forState:UIControlStateNormal];
[sampleButton addTarget:self action:@selector(buttonPressed) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:sampleButton];

Obviously, you will need to adjust the frame origin and size to match your app, as well as the target, selector, and title. And
