看(kàn)到(dào)現(xiàn)在的(de)各式各樣的(de)應$★用(yòng)，好(hǎo)多(duō)應用←α<(yòng)都(dōu)可(kě)以每天更換啓動頁廣告，于是(shì)★↓™決定自(zì)己也(yě)做(zuò)一(yī)個(gè)。
首先打開(kāi)AppDelegate.m
大(dà)家(jiā)都(dōu)知(zhī)道(×¥₩ dào)啓動頁在加載完畢會(huì)自(zì)動執行(xíng)AppDele♣☆εgate didFinishLaunchingWithOpt∞Ωβ¶ions 函數(shù)：
- (BOOL)application:(UIA≤↑∏→pplication *)applica×★tion didFinishLaunchingWithOε∏↕≠ptions:(NSDictionary *)launchOpt§ ₹ions { ≥$
// Ov♠÷erride point for customδ×↓ ization after application&n φ"bsp;launch.
&n>β>§bsp; r↔₹∑eturn YES;
}所以直接将加載廣告代碼寫在這(zhè)個(gè)函數(shù)裡(lǐ)¥♦面就(jiù)對(duì)了(le)：
