ios中自定义button

自定义button

#import <UIKit/UIKit.h>
#define KFont 15

@interface DIYButton : UIButton

@property(nonatomic,copy)NSString *ctrlName;
@end

#import <UIKit/UIKit.h>
#define KFont 15

@interface DIYButton : UIButton

@property(nonatomic,copy)NSString *ctrlName;
@end

自定义 view

@protocol FirstNavViewDelegate;

@interface FirstNavView : UIView

@property(nonatomic,retain)NSArray *data;
@property(nonatomic,assign)id<FirstNavViewDelegate> delegate;
- (id)initWithFrame:(CGRect)frame data:(NSArray *)adata;
@end

@protocol FirstNavViewDelegate <NSObject>

-(void)FirstNavViewClick:(DIYButton *)btn;

@end

#import "FirstNavView.h"
#import "InvoiceInfo.h"
#define KPadding 50
#define KMinTag 10

@implementation FirstNavView

- (id)initWithFrame:(CGRect)frame data:(NSArray *)adata
{
    self = [super initWithFrame:frame];
    if (self) {

        CGFloat width=self.bounds.size.width/adata.count;
        CGFloat height=self.bounds.size.height;
        CGFloat center=width*0.5f;
        for (int i=; i<adata.count; i++) {
            DIYButton *btn=[[DIYButton alloc] init];
            btn.bounds=CGRectMake(, , width-KPadding, height);
            btn.center=CGPointMake(i*width+center, height*0.5f);
            btn.tag=KMinTag+i;
            [btn addTarget:self action:@selector(click:) forControlEvents:UIControlEventTouchUpInside];
            [self addSubview:btn];
            [btn release];
        }
        self.data=adata;//这一句是重点

    }
    return self;
}

-(void)click:(DIYButton *)btn{
    if (self.delegate &&[self.delegate respondsToSelector:@selector(FirstNavViewClick:)]) {
        [self.delegate FirstNavViewClick:btn];
    }
}

-(void)setData:(NSArray *)data{
    if (_data!=data) {
        [_data release];
        _data=[data retain];
        for (int i=; i<data.count; i++) {
            InvoiceInfo *info=data[i];
            int tag=KMinTag+i;
            UIView *view=[self viewWithTag:tag];
            if ([view isKindOfClass:[DIYButton class]]) {
                DIYButton *btn=(DIYButton *)view;
                [btn setImage:[UIImage imageNamed:info.imagUrl] forState:UIControlStateNormal];
                [btn setTitle:info.name forState:UIControlStateNormal];
                btn.ctrlName=info.iPad_ctrls;
            }
        }

    }
}

@end

使用 要实现

FirstNavViewDelegate这个协议

    //一级导航
    NSMutableArray *NavArrary=[NSMutableArray array];
    path=[[NSBundle mainBundle]pathForResource:@"Pad_Menu_First" ofType:@"json"];
    NSError *navError=nil;
    content=[NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:&navError];
    if (navError) {
        NSLog(@"读取%@错误",path);
        return;
    }
    NSArray *arr=[content JSONValue];
    for (NSDictionary *dic in arr) {
        InvoiceInfo *info=[InvoiceInfo Invoice:dic];
        [NavArrary addObject:info];
    }

    FirstNavView *navFirst=[[FirstNavView alloc] initWithFrame:tpRec data:NavArrary];
    navFirst.delegate=self;
    [self.view addSubview:navFirst];
    [navFirst release];

-(void)FirstNavViewClick:(DIYButton *)btn{

NSLog(@"一级导航__%@__%@",btn.titleLabel.text,btn.ctrlName);

[selfpushNavVc:btn.ctrlName];

}
