in the 5.cell is best as large as uiimage, and if it is not the same, it will deform the uiimage. The cell shows a small map. The size of the small map and the ImageView click to enlarge, is to load larger images with large imageview. 6. Be sure to use the real machine when doing tableview. 7. If you are loading data from a network, be sure to do so in a sub-thread (asynchronous loading). 8. The loaded data must be cached locally. Do not add child controls dynamically in 9.cell.

=======================================================The similarities and differences between Java and C + +:Same point: Java and C + + have similar syntax and control structuresDifferent points: Java has no preprocessor or file contains;No pointers, no global variables;No structures and unions;All primitive types (basic types) have a definite size;No operator overloads;only single inheritance;A better definition of the exception, some exception handling is mandatory;No memory leaks;Security f

do not need to use the Futuretask class, it becomes very useful when we intend to rewrite some methods of the future interface and keep the original base implementation. We can just inherit from it and rewrite the methods we need. Read the Java futuretask example to learn how to use it.7. What is the implementation of concurrent containers?Java collection classes are fast failures, which means that when a collection is changed and a thread iterates through the collection using Iterators, the ne

, i.e., all of our training examples lie perfectly on some straigh T line. If J (θ0,θ1) =0, that means the line defined by the equation "y=θ0+θ1x" perfectly fits all of our data. For the To is true, we must has Y (i) =0 for every value of i=1,2,..., m. So long as any of our training examples lie on a straight line, we'll be able to findθ0 andθ1 so, J (θ0,θ1) =0. It is not a necessary that Y (i) =0 for all of our examples. We can perfectly predict the value o

technology operation characteristics: Multi-channel, macro-parallel, micro-serial. Concurrency: In the operating system, there are several programs in a period of time that are running from the start to completion, and the programs are running on the same processor, but only one program is running on the processor at any one time point. Throughput: throughput refers to the number of successful data transfers (measured in bits, bytes, packets, and so on) over a network, device, port, virtual cir

as follows:? 1 str.substring (M, N) + ""This creates an entirely new array of characters representing the new string. The method above sometimes makes the code faster because the garbage collector reclaims large unused strings, leaving only one substring.In Oracle JDK 7, SUBSTRING () creates a new character array without an existing array. The substring () Method in JDK 6 and JDK 7 shows the difference between JDK 6 and JDK 7 substring ().String vs StringBuilder vs StringBufferString vs Stringb

) The variable i indicates which person is reported by the report, each continued to count should be 8 after the touch plus 1, that is, i=i%8+1; 3) in the process of making a count, to skip the already out of the person, the implementation of the array value is set to its subscript, each row out of a position, the position of the element will be changed to 0, if a position corresponding to the array element value is 0, the change position is skipped. The position where the arr

How do I set a graded title for a topic in Word Quiz? In the paper, the general is divided into several major questions, each one will have some small problems. In this case the headline is generally below bold, the small title will be empty two lattice (empty out the big question of the title and punctuation part), the content of the small problem will be indented. As pictured. For this format, I usually handle it in a paragraph. 1, set
