UIButton的基本使用

常用方法

self.newBtn =  ({
UIButton * btn = [UIButton buttonWithType:UIButtonTypeCustom];
        btn.layer.cornerRadius = (48) / 2;
        btn.layer.borderWidth = 1;
        btn.layer.borderColor = [UIColor colorWithHexString:@"#CCCCCC"].CGColor;
        [btn setImage:[UIImage imageNamed:@"nav_wihet"] forState:UIControlStateNormal];
        [btn setImage:[UIImage imageNamed:@"nav_wihet"] 
forState:UIControlStateSelected];
      [btn setFrame:CGRectMake(0, 0, 48, 44)];
      [btn setImageEdgeInsets:UIEdgeInsetsMake(10, 10, 10, 10)]; //扩大响应区范围设置图片对应边距
        [btn setTitle:[NSString stringWithFormat:@"  %@",[@"Face Filter" localString]] forState:UIControlStateNormal];
        btn.titleLabel.font = [UIFont systemFontOfSize:15];
        [btn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
        [btn addTarget:self action:@selector(fullScreenAction) forControlEvents:UIControlEventTouchUpInside];

btn;
