IphoneUI那些細節

UITextView不可編輯，將UITextView中的editable屬性設爲NO。

UIButton 不可點擊，將UIButton 中的enable屬性設爲NO。

UITextField 不可編輯， 將UITextField中的enable屬性設爲NO。

UITextField的輸入提示將提示信息賦給placeholder屬性中。

自定義一種顏色

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

通過RGB來配一種顏色。RGB的參數爲0.0到1.0之間的float型的數據。

可以將空間對象設置一個Tag相當於android中的ID來標示唯一的一個對象。

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];

可以通過viewWithTag這個函數來將該控件的對象賦值給另一個對象。

 

NSNotificationCenter 的使用

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

其中changeTheme是一個方法名：

- (void)changeTheme:(NSNotification *)notification
{
	NSString *themeName = [MessageCenter shareInstance].themeSetName;
	NSDictionary *array = (NSDictionary *)[[DataCenter shareInstance] getTheme:themeName];
	if ([themeName isEqualToString:@"默認"]) {
		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:@"絢黑"]) {
		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;
	}
}

發送改變主題的消息

//發送切換主題消息
	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;
	}

零零散散的寫了一些在項目中遇到一些常用的UI，也是比較特殊一點。

不知道是否對大家有用。
