小编Nir*_*thi的帖子

它是什么意思,我该如何解决它:

pod install
/Library/Ruby/Site/2.0.0/rubygems.rb:250:in `find_spec_for_exe': can't find gem cocoapods (>= 0.a) (Gem::GemNotFoundException)
from /Library/Ruby/Site/2.0.0/rubygems.rb:278:in `activate_bin_path'
from /usr/local/bin/pod:22:in `<main>'

我使用 @IBInspectable 创建 UIView 扩展来设置角半径，但是当我旋转设备时它无法正常工作

import UIKit
import Foundation

extension UIView {

@IBInspectable
var cornerRadius: CGFloat {
     get {
        return layer.cornerRadius
     }
     set {
        layer.cornerRadius = newValue
     }
   }
}

我在以下限制下拍摄了图像视图

当我以纵向模式运行应用程序时，输出将为

但当我旋转设备时它不起作用

private func makeRequest<T where T:MappableNetwork>(method method: Alamofire.Method, url: String,
                         parameters: [String: AnyObject]?, keyPath: String, handler: NetworkHandler<T>.handlerArray) -> Request {

    let headers = [
        "Authorization": "",
        ]

    return Alamofire
        .request(method, url, parameters: parameters, encoding: .URL, headers: headers)
        .validate()
        .responseArray(keyPath: keyPath) { (response: Alamofire.Response<[T], NSError>) in
            if let error = response.result.error {
                if let data = response.data {
                    let error = self.getError(data)
                    if error != nil {
                        handler(.Error(error: error!))
                        return
                    }
                }
                handler(.Error(error: error))
            } else if let objects = response.result.value { …

我尝试在 UIWebView 中显示阿拉伯语内容。但出现屏幕截图所示的错误。那么如何解决呢
