 # JXTAlertController
 基于UIAlertController的封装，利用链式语法，使得UIAlertController使用起来更简单。
+
+## JXTAlertController(>=iOS8)
+
+### 1.alert
+```objective-c
+[self jxt_showAlertWithTitle:@"title"
+                     message:@"message"
+           appearanceProcess:^(JXTAlertController * _Nonnull alertMaker) {
+    alertMaker.
+    addActionCancelTitle(@"cancel").
+    addActionDestructiveTitle(@"按钮1");
+} actionsBlock:^(NSInteger buttonIndex, UIAlertAction * _Nonnull action, JXTAlertController * _Nonnull alertSelf) {
+    if (buttonIndex == 0) {
+        NSLog(@"cancel");
+    }
+    else if (buttonIndex == 1) {
+        NSLog(@"按钮1");
+    }
+}];
+```
+
+### 2.添加textField
+```objective-c
+[self jxt_showAlertWithTitle:@"title"
+                     message:@"message"
+           appearanceProcess:^(JXTAlertController * _Nonnull alertMaker) {
+    alertMaker.
+    addActionDestructiveTitle(@"获取输入框1").
+    addActionDestructiveTitle(@"获取输入框2");
+    
+    [alertMaker addTextFieldWithConfigurationHandler:^(UITextField * _Nonnull textField) {
+        textField.placeholder = @"输入框1-请输入";
+    }];
+    [alertMaker addTextFieldWithConfigurationHandler:^(UITextField * _Nonnull textField) {
+        textField.placeholder = @"输入框2-请输入";
+    }];
+} actionsBlock:^(NSInteger buttonIndex, UIAlertAction * _Nonnull action, JXTAlertController * _Nonnull alertSelf) {
+    if (buttonIndex == 0) {
+        UITextField *textField = alertSelf.textFields.firstObject;
+        [self logMsg:textField.text];//不用担心循环引用
+    }
+    else if (buttonIndex == 1) {
+        UITextField *textField = alertSelf.textFields.lastObject;
+        [self logMsg:textField.text];
+    }
+}];
+```
