ASIHTTPRequest类库
在练习Http请求的时候,希望通过Charles之类的功能能监控到请求状态
便于调试,但是搜了下相关文章,没有发现NSURLRequest配置http proxy的相关信息
倒是又推荐使用ASIHTTPRequest

接下来准备尝试下
selector
#ifdef __cplusplus 倒底是什么意思?
JSONKit
IOS对JSON数据的处理,大多推荐JSONKit

iOS Jsonkit 用法简要说明
http://blog.csdn.net/w237or45/article/details/7827796
不过放到工程里之后显示一串error
- 由于JSONKit没有使用ARC,所以使用时不要忘了在build phases -》compile sources 选择文件后面加-fno-objc-arc参数。
- Xcode升级出现的警告
array->isa = _JKArrayClass; 改成 object_setClass(array, _JKArrayClass);
dictionary->isa = _JKDictionaryClass; 改成 object_setClass(dictionary, _JKDictionaryClass);
- 消除Xcode 5中JosnKit类库的bit masking for introspection of objective-c 警告

[Cocos2dx]设置竖屏的方法
- 修改ios/RootViewController.mm 下函数
- (BOOL) shouldAutorotate{
return NO; //YES改成NO
}
UITextField 与 键盘的关闭
loadView内代码创建了一个textField,头文件内并没有声明
添加到view中
然后需要对呼出的键盘做一下关闭功能的配置
网上找了一圈,差不多就是在两种场景下需要关闭键盘
一是点击键盘上的return键,一是点击textField以外的区域
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
// 触摸背景,关闭键盘
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [touches anyObject];
UIView *view = (UIView *)[touch view];
NSLog(@"touch");
if(view == self.view){
// 如果textField使用局部对象,这里就需要采用ViewWithTag的方式来取到textView。从前端的角度来说可能是类似于dom选择器。
// 更好的方法是将textField控件再头文件进行声明。这样性能更好,代码简洁
// [self.textField resignFirstResponder];
}
}
掌握notification、KVO
制作framework
UITableView Crashed
self.tableView.dataSource = self;
self.tableView.delegate = self;
这两句在代码中出现警告提示:
~/IosSpace/Start/Start/ListViewController.m:57:31: Assigning to 'id' from incompatible type 'ListViewController *const __strong'
修改ListViewController.h文件中
@interface ListViewController : UIViewController
为
@interface ListViewController : UITableViewController后警告消失
但是在编译后模拟器中打开这个Controller时崩溃
实现在ios开发中的App滑动封面 UIScrollView
了解ViewWithTag并编写Demo
