IphoneUI那些细节

UITextView不可编辑，将UITextView中的editable属性设为NO。

UIButton 不可点击，将UIButton 中的enable属性设为NO。

UITextField 不可编辑， 将UITextField中的enable属性设为NO。

UITextField的输入提示将提示信息赋给placeholder属性中。

自定义一种颜色

UIColor *myColor = UIColor coloWithRed:0.8 green:0.3 blue:0.6 alpha:1];

通过RGB来配一种颜色。RGB的参数为0.0到1.0之间的float型的数据。

可以将空间对象设置一个Tag相当于android中的ID来标示唯一的一个对象。

如：

UITextField *verifyPasswordText = [[UITextField alloc] initWithFrame:CGRectMake(HC_Login_LabelWidth+10,                                                                                                         10+1*(HC_Login_LabelHeight+HC_Login_LabelSpace),                                                                                1.5*HC_Login_LabelWidth, 0.15*200)];
verifyPasswordText.tag = 1003;
verifyPasswordText.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
verifyPasswordText.placeholder = MORE_ENTERPASSWORDAGAIN;
verifyPasswordText.returnKeyType = UIReturnKeyDone;
verifyPasswordText.secureTextEntry = YES;
[verifyPasswordText addTarget:self action:@selector(textFieldDoneEditing:) forControlEvents:UIControlEventEditingDidEndOnExit];
verifyPasswordText.borderStyle = UITextBorderStyleRoundedRect;
verifyPasswordText.enabled = NO;
verifyPasswordField = verifyPasswordText;
[self.setPassword addSubview:verifyPasswordText];
[verifyPasswordText release];

UITextField *verifyWordTextField2 = (UITextField *)[self.view viewWithTag:1003];

可以通过viewWithTag这个函数来将该控件的对象赋值给另一个对象。

 

NSNotificationCenter 的使用

[[NSNotificationCenter defaultCenter] addObserver:self 
				selector:@selector(changeTheme:) 
				name:ThemeFlag object:nil];

其中changeTheme是一个方法名：

- (void)changeTheme:(NSNotification *)notification
{
	NSString *themeName = [MessageCenter shareInstance].themeSetName;
	NSDictionary *array = (NSDictionary *)[[DataCenter shareInstance] getTheme:themeName];
	if ([themeName isEqualToString:@"默认"]) {
		UIImage *icon = [array objectForKey:@"navBg"];
		self.navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque;
		self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:0.3 green:0.3 blue:0.3 alpha:1];
		self.navigationController.navigationBar.layer.contents = (id)icon.CGImage;
	}
	
	if ([themeName isEqualToString:@"绚黑"]) {
		UIImage *icon = [array objectForKey:@"navBg"];
		self.navigationController.navigationBar.barStyle = UIBarStyleDefault;
		self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:0.75 green:0 blue:0 alpha:1];
		self.navigationController.navigationBar.layer.contents = (id)icon.CGImage;
	}
}

发送改变主题的消息

//发送切换主题消息
	switch (indexPath.row)
	{
		case 0:
		{
			[[MessageCenter shareInstance].settingDic setObject:@"0" forKey:@"setTheme"]; 
			[MessageCenter NotificationCenterToChat:ThemeFlag userInfo:nil];
			NSDictionary *array = (NSDictionary *)[[DataCenter shareInstance] getTheme:ILIAO_THEME_PERMIT];
			if ([array count] > 0)
			{
				UIImage *icon = [array objectForKey:@"navBg"];
				self.navigationController.navigationBar.barStyle = UIBarStyleDefault;
				self.navigationController.navigationBar.tintColor = [UIColor colorWithHexString:@"#003892"];
				self.navigationController.navigationBar.layer.contents = (id)icon.CGImage;

				//tableView.backgroundColor = [UIColor darkGrayColor];
				//tableView.separatorColor = [UIColor grayColor];	
			}
			[self saveSettingPlist:[MessageCenter shareInstance].settingDic];
			break;
		}
		case 1:
		{
			[[MessageCenter shareInstance].settingDic setObject:@"1" forKey:@"setTheme"]; 
			[MessageCenter NotificationCenterToChat:ThemeFlag userInfo:nil];
			NSDictionary *array = (NSDictionary *)[[DataCenter shareInstance] getTheme:ILIAO_THEME_BRIGHT_BLACK];
			if ([array count] > 0)
			{
				UIImage *icon = [array objectForKey:@"navBg"];
				self.navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque;
				self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:0.75 green:0 blue:0 alpha:1];
				self.navigationController.navigationBar.layer.contents = (id)icon.CGImage;
				//self.navigationController.navigationBar.barStyle = UIBarStyleDefault;
				//tableView.backgroundColor = [UIColor darkGrayColor];
				//tableView.separatorColor = [UIColor grayColor];	
			}
			[self saveSettingPlist:[MessageCenter shareInstance].settingDic];
			break;
		}
		default:
			break;
	}

零零散散的写了一些在项目中遇到一些常用的UI，也是比较特殊一点。

不知道是否对大家有用。
